Answer:

Venus

Explanation:

Answer:

Explanation:

Force = mass * acceleration (Newton's second law of motion)

Given

Mass = 32kg

Get the acceleration using the expression d = 1/2at^2

3.5 = 1/2 (a)2.5^2

3.5 = 3.125a

a = 3.5/3.125

a = 1.12m/s^2

Get the net force;

F =  3.2 * 1.12

F = 35.84N

Hence the net force used to accelerate is 35.84N

The value of x, y, and z in the equation for F is x = 1, y = 1/2, and z = 2.

To use the method of dimensions, we need to first identify the fundamental dimensions involved in the problem. The fundamental dimensions in this problem are:

Length (L)

Mass (M)

Time (T)

Now let's consider each term in the equation for F:

K is non-dimensional, so it doesn't have any fundamental dimensions.

a has dimensions of length (L).

p has dimensions of mass per unit volume, or density, which is mass (M) divided by length cubed (L³).

v has dimensions of length per unit time, or velocity, which is length (L) divided by time (T).

Using these fundamental dimensions, we can write the dimensional formula for each term in the equation for F:

[F] = M L T⁻² (force)

[K] = 1 (dimensionless)

[a] = L

[p] = M L⁻³

[v] = L T⁻¹

Substituting these dimensional formulas into the equation for F, we get:

M L T⁻² = \((KL)^x (ML^{-3})^{y} (LT^{-1}})^{z}\)

Simplifying, we can rewrite this as:

M L T⁻² = K \(M^y L^{x-3y+z} T^{-z}\)

Equating the dimensions of both sides, we get the following system of equations:

\(M = K M^{y}\)

Solving for x, y, and z, we get:

x = 1

y = 1/2

z = 2

Answer:

All rocks hit the ground with the same speed.

Explanation:

The magnitude of the vertical velocity under gravity changes by approximately 9.81 m/s each second

The option that correctly relates the magnitude, \(v_{y}\), of the vertical velocity is the option;

\((v_{y1} = v_{y1}) \geq v_{y3}\)

Reason:

The possible question options are; \((v_{y1} = v_{y1}) \geq v_{y3}\), \(v_{y1}> v_{y3} > v_{y2}\), \(v_{y2}> v_{y3} > v_{y1}\), \(v_{y1}= v_{y2} = v_{y3}\)

Known parameters;

The speed of the rocks = u

The height of the platform from which the rocks are thrown = h₀

The given direction in which the balls are thrown are;

Rock 1; Direction  = 45° above the horizontal

Rock 2; Direction = 45° below the horizontal

Rock 3; Direction = 0° or in the horizontal direction

The vertical component of the speed of Rock 1= -u·sin(45°)

Vertical component of the speed of Rock 2 = u·sin(45°)

Vertical component of the speed of Rock 3 = u·sin(0°) = 0

The velocity of the rock is given by

v² = u² - 2·g·h₀

\(v = \pm \sqrt{u^2 - 2 \cdot g \cdot h_0}\)

Where g is taken as negative, we have;

\(v = \pm \sqrt{u^2 + 2 \cdot g \cdot h_0}\)

Therefore, the vertical velocity the rocks, Rock 1 and Rock 2, thrown with magnitude of velocity, \(|v_y| = |u \cdot sin(45^{\circ})|\) is the same during the vertical motion of the ball at the same height, but change only in sign

\(At \ a \ given \ height, \ h_0, \ v_{y1} = v_{y2}\)

\(Therefore, \ before \ the \ rocks \ hit \ the \ ground, \ v_{y1} = v_{y2}\)

The initial vertical velocity of Rock 3, \(v_{y3}\) = 0, therefore;

Therefore, for the correct option, we have;

Conductivity and ductility are properties of metals that determine their ability to conduct electricity and be molded into different shapes, respectively.

Conductivity refers to a metal's ability to conduct electricity. Metals are known for their high conductivity, meaning they allow electricity to flow through them easily. This property is due to the fact that metals have free electrons in their outer shell, which are free to move and carry an electrical charge. The conductivity of a metal can be affected by its temperature and impurities, as well as its atomic structure. Ductility, on the other hand, refers to a metal's ability to be stretched or drawn into a wire without breaking. This property is due to the way the atoms in a metal are arranged and the way they interact with each other. Ductile metals are malleable, meaning they can be bent, shaped, and molded without breaking. Metals with high ductility are ideal for shaping into wire, pipes, and other products that require flexibility and strength. In summary, conductivity and ductility are important properties of metals that determine their ability to conduct electricity and be shaped into various forms.

Given;

mass of the sports car, m = 500 kg

initial velocity of the sports car, u = 0

final velocity of the sport car, v = 30 m/s

time of motion of the car, t = 6 s

The distance traveled by the sports car is calculated as;

\(s = (\frac{u+v}{2} )t\\\\s = (\frac{0+30}{2} ) \times 6\\\\s = 15 \times 6\\\\s = 90 \ m\)

Therefore, the distance traveled by the sports car is 90 m

Answer: v = 40 m/5

Explanation:

40 J = 1/2 (105) v^2

1600 = v^2

v = 40 m/5

The velocity of the arrow weighing 50 g or 0.05 Kg to have a kinetic energy of 40 joules is 40 m/s.

Kinetic energy is the energy generated in a body by virtue of the motion of the body. It is dependent on the mass and velocity of the body by the relation written below:

Ke = 1/2 mv²

Given the mass of the arrow = 50 g = 0. 05 kg

kinetic energy = 40 J

Thus velocity of the arrow = √(2 Ke / m)

                                            = √(2 × 40 J / 0.05 Kg)

                                            = 40 m/s .

Therefore, the velocity of the arrow will be 40 m/s

Answer:approximately 4.67 m/s.

Explanation:To find the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s, we need to calculate the total distance traveled by the particle during this time interval and divide it by the elapsed time.

From the graph, we can see that the particle starts at x = 0 m and moves to the right until it reaches x = 8 m at t = 2.0 s. Then, it moves back to the left until it reaches x = 2 m at t = 4.0 s.

The total distance traveled by the particle during this time interval is the sum of the distances it traveled while moving to the right and while moving to the left. The distance traveled while moving to the right is 8 m, and the distance traveled while moving to the left is 6 m (from x = 8 m to x = 2 m). Therefore, the total distance traveled is 8 m + 6 m = 14 m.

The elapsed time is 4.0 s - 1.0 s = 3.0 s.

So, the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is:

average speed = total distance traveled / elapsed time

average speed = 14 m / 3.0 s

average speed ≈ 4.67 m/s

Therefore, the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is approximately 4.67 m/s.

the repulsive force between the two pith balls is approximately 1.79 x 10^-2 Newtons.

The repulsive force between two charged objects can be calculated using Coulomb's Law. Coulomb's Law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

The equation for Coulomb's Law is:

F = k * (q1 * q2) / r^2

where F is the force, k is the electrostatic constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the objects, and r is the distance between them.

In this case, both pith balls have equal charges, so q1 = q2 = 30.7 nC (nanoCoulombs) = 30.7 x 10^-9 C.

The distance between the pith balls is r = 12.1 cm = 12.1 x 10^-2 m.

Substituting the values into the equation:

F = (8.99 x 10^9 Nm^2/C^2) * ((30.7 x 10^-9 C)^2) / ((12.1 x 10^-2 m)^2)

Calculating this expression will give us the repulsive force between the pith balls.

F ≈ 1.79 x 10^-2 N

Therefore, the repulsive force between the two pith balls is approximately 1.79 x 10^-2 Newtons.

The acceleration of the baseball is 26 m/s², calculated by dividing the change in velocity by the time taken.

To determine the acceleration of the baseball, we need to use the formula for acceleration: acceleration (a) equals the change in velocity (Δv) divided by the time taken (t). In this case, the baseball's initial velocity is assumed to be zero since it starts from rest in the pitcher's hand.

The final velocity is given as 39 m/s, and the time taken is 1.5 seconds. Therefore, the change in velocity (Δv) is 39 m/s - 0 m/s = 39 m/s. Dividing this change in velocity by the time taken (1.5 s), we find that the acceleration of the baseball is 26 m/s².

Explanation:

The potential energy of an object has the following formula

         Potential energy = mgh

      where m = mass of the object

This means that the potential energy of an object depends upon its mass, acceleration due to gravity, and height.

In the given situation we have a bucket full of water. If the mass and acceleration due to gravity are not changed, the only way the potential energy can be decreased is by reducing the height of the bucket full of water.

This can be done by: -

         (i) Lifting the bucket full of water in such a way that you

             decrease its height as compared to the bench.

        (ii) Put the bucket full of water on a stool whose height is

All of the statements about the cosmic microwave background radiation (CMB) are true except for the statement: "The radiation comes from the center of the explosion of the big bang, and it is hoped that it will tell us where in the universe the big bang actually occurred."

The cosmic microwave background radiation is a pervasive form of radiation that fills the entire universe. It is not localized to a specific point or direction in space, so it does not come from the center of the explosion of the big bang. Instead, it is observed uniformly in all directions.

The CMB is considered the remnant radiation from the early universe, specifically from a time called recombination when the universe cooled down enough for neutral atoms to form. Prior to recombination, the universe was hot and dense, consisting of a plasma of charged particles that effectively scattered photons. However, as the universe expanded and cooled to a certain point, protons and electrons combined to form neutral hydrogen atoms, allowing photons to travel freely without being scattered. The CMB represents the light that was emitted at this pivotal moment and has been traveling through space ever since, gradually redshifting over billions of years.

The CMB provides important insights into the early universe. Its spectrum corresponds to a nearly perfect black body curve, with a temperature of approximately 2.7 Kelvin. This temperature measurement is consistent with the idea that the CMB originated from the recombination era, around 380,000 years after the Big Bang. By studying the CMB, scientists can gather valuable information about the composition, age, and evolution of the universe during its early stages, including the fluctuations that eventually led to the formation of galaxies and large-scale structures.

However, the CMB itself does not reveal the precise location or point of origin of the Big Bang. It provides valuable clues about the early universe but does not directly tell us where the Big Bang occurred within the universe. The Big Bang is generally understood to have occurred uniformly throughout space, initiating the expansion of the universe as a whole.

The **magnitude of the angular momentum** (in kg · m^2/s) of the car relative to the center of the racetrack is **50,000 kg · m^2/s**.

Angular momentum is given by the equation: L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity. In this case, the car is moving in a circular path, so its angular velocity can be calculated using the equation ω = v/r, where v is the linear velocity and r is the radius of the circular track.

Given that the mass of the car is 1000 kg, its linear velocity is 50 m/s, and the radius of the circular track is 100 m, we can calculate the angular velocity as follows: ω = 50 m/s / 100 m = 0.5 rad/s.

Next, we need to calculate the moment of inertia. For a point mass moving in a circular path, the moment of inertia is given by I = mr^2, where m is the mass of the object and r is the distance from the rotation axis (in this case, the center of the racetrack). Plugging in the values, we get I = 1000 kg × (100 m)^2 = 10,000,000 kg · m^2.

Finally, we can calculate the angular momentum: L = Iω = 10,000,000 kg · m^2 × 0.5 rad/s = 5,000,000 kg · m^2/s. Hence, the magnitude of the angular momentum relative to the center of the racetrack is 50,000 kg · m^2/s.

The probability density function of X is plotted for a=1/2 and a=2.

The expected value of X (E[X]) is determined.

The expected value of 1/X (E[1/X]) is determined.

The variance of X (V[X]) is determined.

The median of X is determined.

When a=1/2, the probability density function of X is given by p(X=x∣a)=((1/2)+1)x(1/2)^0=(3/2)x for x∈[0,1]. When a=2, the probability density function becomes p(X=x∣a)=(2+1)x^2=3x^2 for x∈[0,1]. To plot the probability density function, we can assign different values of x within the range [0,1], calculate the corresponding probabilities using the given formulas, and plot the points on a graph.

The expected value of X (E[X]) is calculated by integrating the product of X and its probability density function over the range [0,1]. For a=1/2, E[X] = ∫(x * (3/2)x) dx from 0 to 1. For a=2, E[X] = ∫(x * 3x^2) dx from 0 to 1. By evaluating these integrals, we can determine the expected values.

The expected value of 1/X (E[1/X]) is calculated similarly to E[X], but instead of integrating X, we integrate 1/X using the respective probability density functions for different values of a.

The variance of X (V[X]) can be computed by taking the second moment of X (E[X^2]) minus the square of the first moment (E[X]) squared. V[X] = E[X^2] - (E[X])^2. By calculating E[X^2] using the probability density function and the expected values obtained in step 2, we can determine the variances for different values of a.

The median of X is the value of X such that the cumulative distribution function (CDF) is equal to 0.5. To find the median, we integrate the probability density function from 0 to the median value and set it equal to 0.5. Solving for the median provides its value in terms of the parameter a.
