Is the sun making the side walk a chemical or phsical change

Answer:

The tiny object's acceleration will be much greater.

Explanation:

Because of Newton's second law of motion, (which is F=ma or Force= Mass*acceleration), then if the force maintains the same (which in this case it does, because it says 50 N to both obejcts) and  one mass was much greater than the other, then the ould be less for the more massive object and much greater for the lighter object.

For example:  If 50 N were applied to a 500 kg object and a 50 kg object, then theformulas for each (respectively) are:

50 = 500*acceleration

and

50 = 50*acceleration

(Because of Newtons Second Law of Motion)

Then, solving for the equations, we get for equation 1:

Acceleration = .1 m/s^2

And for equation 2:

Accleration = 1 m/s^2

Thus, you can see that more massive objects (when applied he same amount of force as the smaller object) clearly have less accleration than the smaller objects.

The variation of water depth at spreading centers (ridges) controlled by isostasy  as convective cooling cools the rocks much more effectively the than heat conduction.

When heat transfer takes place between the two fluids in direct or indirect contact.

The lithosphere cools when it moves away from the ridge axis by sea floor spreading. The cooler rocks have low density, so the sea floor gets deeper as the lithosphere gets more dense.

Thus, the convective cooling cools the rocks much more effectively the than heat conduction.

Answer:

5 m/s due West

Explanation:

​(a) The change in speed of the car can be found using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the change in speed is the magnitude of the change in velocity, and is given by:

change in speed = sqrt((25 m/s)^2 + (30 m/s)^2) = 39.05 m/s (rounded to two decimal places)

Therefore, the change in speed of the car is approximately 39.05 m/s.

(b) The change in velocity of the car can be found by subtracting the initial velocity from the final velocity. The initial velocity was 30 m/s due East, and the final velocity was 25 m/s due South. To subtract these velocities, we need to use vector subtraction. This involves breaking the velocities into their x and y components and subtracting the components separately. The x component of the initial velocity is 30 m/s, and the x component of the final velocity is 0 m/s. The y component of the initial velocity is 0 m/s, and the y component of the final velocity is -25 m/s. Therefore, the change in velocity of the car is:

change in velocity = final velocity - initial velocity = (-30 m/s) - (-25 m/s) = -5 m/s due West

Therefore, the change in velocity of the car is 5 m/s due West.

The value of each charge is 4.22 x 10⁻⁵ C

Explanation:

Given;

distance between the two identical charges, d = 2 m

the force of repulsion between these two charges, F = 4N

Apply Coulomb's law;

\(F = \frac{kq_1q_2}{r^2} \\\\but \ q_1 =q_2,then \ let \ q_1 =q_2 = q\\\\F = \frac{kq^2}{r^2}\\\\q^2 = \frac{Fr^2}{k}\\\\q^2 = \frac{4*2^2}{9*10^9} \\\\q ^2 = 1.7778*10^{-9}\\\\q = \sqrt{1.7778*10^{-9}}\\\\q =4.22 *10^{-5} C\\\\q= q_1=q_2= 4.22 *10^{-5} C\)

Therefore, the value of each charge is 4.22 x 10⁻⁵ C

Answer:kinetic

Explanation:

To determine the magnitude of the acceleration of the motorcycle, we need to know the force of friction acting on the wheels. The force of friction is equal to the coefficient of friction multiplied by the normal force acting on the wheels, which is equal to the weight of the motorcycle and rider. The weight of the motorcycle and rider can be calculated by multiplying the mass by the acceleration due to gravity (9.8 m/s^2). So, the force of friction acting on the wheels of the motorcycle is equal to 0.88 * 196 kg * 9.8 m/s^2 = 1661.28 N.

The acceleration of the motorcycle is equal to the force of friction divided by the mass of the motorcycle and rider. So, the acceleration of the motorcycle is equal to 1661.28 N / 196 kg = 8.45 m/s^2.

As we walk across a period from left to right, the effective nuclear charge rises, whereas it falls as we move down the group. The element with the lowest effective nuclear charge will be found on the left side of the periodic table. The periodic table's group 1 includes H, Li, and Na.

A fluorine atom's nucleus has a charge Z of 9, but the valence electrons are mostly screened by the core electrons—four electrons from the 1s and 2s orbitals—and to a lesser extent by the 7 electrons in the 2p orbitals. The cation of sodium thus has the highest effective nuclear charge.

In spite of being in the same period as sodium and phosphorus, chlorine has the most protons in its shell (the most inside the same period), giving it the highest effective nuclear charge.

The amount of shielding electrons may be calculated by deducting the amount of valence electrons from the overall number of electrons in the atom or ion.

The  force is  \(F = 3587.2 \ N\)

Explanation:

From the question we are told that

   The  diameter is  \(d = 1.4 \ mm = 0.0014 \ m\)

    The pressure is  \(P = 2.33*10^{9} \ N/m^2\)

Generally the radius is mathematically represented as

        \(r = \frac{0.0014}{2}\)

        \(r = 0.0007 \ m\)

 The  cross-sectional area of the nail is mathematically represented as

       \(A = \pi r^2\)

=>     \(A = 3.142 * 0.0007 ^2\)

=>    \(A = 1.54 *10^{-6}\)

Generally the pressure is mathematically represented as

        \(P = \frac{F}{A}\)

=>      \(F = P * A\)

=>       \(F = 1.54*10^{-6} * 2.33*10^{9}\)

=>      \(F = 3587.2 \ N\)

If a white dwarf gains sufficient mass , it can undergo a type I supernova. This occurs when the white dwarf reaches Chandrasekhar limit, which is approximately 1.4 times mass of the Sun.

If a white dwarf does not gain sufficient mass to undergo a type I supernova, it will eventually cool down and become a black dwarf. A brown dwarf is a failed star that is not massive enough to undergo nuclear fusion in its core, and so it emits very little light or heat.

A type II supernova occurs when a massive star runs out of fuel and its core collapses, leading to a catastrophic explosion. This is distinct from a type I supernova, which involves a white dwarf.

To calculate the magnitude of the force that would exactly counterbalance these three forces, we need to use the principle of vector addition. This involves combining the three forces vectorially to find the net force acting on the object.

First, we need to find the resultant of the two forces that are at an angle of 90 degrees to each other. This can be done using the Pythagorean theorem:

Resultant = √(25² + 12²) = √(625 + 144) = √769 = 27.74 N

Next, we need to find the net force acting on the object by adding the third force (4 N) to the resultant of the first two forces (27.74 N).

Net force = 4 N + 27.74 N = 31.74 N

Therefore, the magnitude of the force that would exactly counterbalance these three forces is 31.74 N.

I option 1 we unit as m/s  which simply shows the unit of Velocity. whereas option 2 is 2.4 kg/m which is not true as we already calculated as it must be kgm/s similarly in the case of option 3 2kg/s which again is not exactly the same SI unit of what we calculated before using equating the equation.

Explanation:

We can represent the situation with the following figure

Now, by the conservation of energy, we can write the following equation

Where m is the mass, vi is the initial velocity, g is the gravity, h is the height, Ff is the force of friction, d is the distance traveled by the sledge, and vf is the final velocity.

Using the free body diagram, we get that the force of friction is equal to

Now, we can replace the expression for Ff in the equation above and solve for the coefficient of friction μ

Replacing g = 9.8 m/s², d = 16 m, vi = 3 m/s, h = 8 m, and vf = 12 m/s, we get

Therefore, the coefficient of friction is 0.08
