if a large bust and small cardboard going the same speed which vehicle has more kinetic energy
Answers
Answer:
bust
Explanation:
At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.
Answer:
Bust
Explanation:
the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

A 6.00 volt battery is in a circuit with two resistors, A and B, connected in parallel. If the current flowing
out of the battery is 90.0 mA, what is the value in ohms of B if A is 100 ?
Answers
Answer: \(200\Omega\)
Explanation:
Given
The battery used is 6V in magnitude
The current flow is 90 mA
If the resistance of A is \(100\Omega\)
Net resistance of the circuit is
\(R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega\)
If A and B are in parallel then their net resistance must be \(\frac{200}{3}\)
\(\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega\)

Answers
Answer:

Explanation:
Given parameters:
M1 = 20kg
V1 = 2m/s
V2 = 0m/s
M2 = 10kg
Unknown:
V = ?
Solution:
As with all systems, the momentum must be conserved and it implies that the starting and ending momentum be the same.
M1 V1 + M2 V2 = V (M1 + M2)
M1 is the mass of the big red fish
V1 is the velocity of the big red fish
V2 is the velocity of the green fish
M2 is the mass of the green fish
V is the velocity after swallowing
(20 x 2) + (10 x 0) = V (20 + 10)
40 = 30V

The value of the electric field at a distance
of 60.7 m from a point charge is 61.9 N/C and
is directed radially in toward the charge.
What is the charge? The Coulomb constant
is 8.98755 × 10^9 N · m^2/C^2
.
Answer in units of C.
Answers
Answer:
Approximately \((-2.54) \times 10^{-5}\; {\rm C}\).
Explanation:
The magnitude of the electric field around a point charge can be found with the equation:
\(\begin{aligned} E &= \frac{k\,q}{r^{2}}\end{aligned}\), where:
\(E\) is the magnitude of the electric field,\(k = 8.98755 \times 10^{9}\; {\rm N\cdot m^{-2}\cdot C^{-2}}\) is the Coulomb constant, \(q\) is the magnitude of the point charge, and\(r = 60.7\; {\rm m}\) is the distance from the point charge.Rearrange this equation and solve for the magnitude \(q\) of this point charge:
\(\begin{aligned}q &= \frac{r^{2}\, E}{k} \\ &= \frac{(60.7)^{2}\, (61.9)}{8.98755}\; {\rm C} \\ &\approx 2.54\times 10^{-5}\; {\rm C}\end{aligned}\).
Note that the sign of electric charges can be either positive or negative. The direction of field lines around this point charge provides info on the sign of this electric charge.
By convention, the direction of electric field lines at a particular position is the same as the direction of the force on a positive electric test charge at that location. Since the electric field around this point charge points towards the charge, it means a positive charge would be attracted to this point charge.
Charges of opposite signs attract each other. For the point charge in this question to attract a positive test charge, it must be true that this point charge has a negative sign. Hence, this point charge would be \((-2.54) \times 10^{-5}\; {\rm C}\).
An overhead transmission cable for electrical power is 2000 m long and consists of two parallel copper wires, each encased in insulating material. A short circuit has developed somewhere along the length of the cable where the insulation has worn thin and the two wires are in contact. As a power-company employee, you must locate the short so that repair crews can be sent to that location. Both ends of the cable have been disconnected from the power grid. At one end of the cable (point A), you connect the ends of the two wires to a 9. 00-V battery that has negligible internal resistance and measure that 2. 26 A of current flows through the battery. At the other end of the cable (point B), you attach those two wires to the battery and measure that 2. 05 A of current flows through the battery.
Required:
How far is the short from point A?
Answers
The short in the overhead transmission cable is approximately 762.5 meters away from point A. To determine the distance of the short from point A, we can use the concept of resistance.
When the two wires are in contact, they effectively form a parallel circuit. The total resistance of the cable can be calculated using the formula:
\(\[\frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2}\]\)
where \(\(R_{\text{total}}\)\) is the total resistance, \(\(R_1\)\) is the resistance from point A to the short, and \(\(R_2\)\) is the resistance from the short to point B.
From Ohm's law, we know that the current I is equal to the voltage V divided by the resistance R. In this case, the current at point A is 2.26 A and the current at point B is 2.05 A. Since the battery has negligible internal resistance, the current at both ends of the cable is the same as the current flowing through the cable.
Using Ohm's law, we can write two equations:
\(\(2.26 = \frac{9}{R_1}\) and \(2.05 = \frac{9}{R_2}\)\)
Solving these equations, we find that \(\(R_1 = 3.982\)\) ohms and \(\(R_2 = 4.390\)\) ohms.
Since the resistances are inversely proportional to the distances, we can write:
\(\(\frac{R_1}{R_2} = \frac{d_2}{d_1}\)\)
Substituting the values, we have:
\(\(\frac{3.982}{4.390} = \frac{d_2}{d_1}\)\)
Simplifying, we find:
\(\(d_2 = \frac{4.390}{3.982} \times d_1\)\)
Given that the total length of the cable is 2000 meters, we can write:
\(\(d_1 + d_2 = 2000\)\)
Substituting the value of \(\(d_2\)\), we have:
\(\(d_1 + \frac{4.390}{3.982} \times d_1 = 2000\)\)
Simplifying, we find:
\(\(d_1 = \frac{2000}{1 + \frac{4.390}{3.982}}\)\)
Evaluating the expression, we find that \(\(d_1 \approx 762.5\)\) meters.
Therefore, the short in the overhead transmission cable is approximately 762.5 meters away from point A.

Suppose a spectral line of hydrogen, normally at 500 nm when measured in a lab on Earth, is observed in the spectrum of a star to be at 500.3 nm. This is called a red shift because the wavelength is longer (and red is on the long-wavelength side of the visible spectrum). How fast is the star moving away from Earth? Give your answer in m/s. Hint: follow example 5.6. Compare in particular to the "Check your learning" calculation, and note that larger Δλ means larger speed.
Answers
The star is moving away from Earth at a velocity of 1.8 x 106 m/s.
The Doppler Effect describes the shift in wavelength of a wave when the source is moving in relation to the observer. The shift can be observed in sound waves, light waves, and other waves.
The Doppler Effect can be used to determine the velocity of objects moving away from an observer, as in the case of stars moving away from Earth.
The velocity of a star moving away from Earth can be determined using the equation:
v = Δλ/λ x c, Where v is the velocity of the star, Δλ is the shift in wavelength of the spectral line, λ is the wavelength of the spectral line measured in the lab on Earth, and c is the speed of light (3.00 x 108 m/s).
In this case, the shift in wavelength of the spectral line is Δλ = 500.3 nm - 500 nm = 0.3 nm.
The wavelength of the spectral line measured in the lab on Earth is λ = 500 nm.
Plugging in these values to the equation above: v = Δλ/λ x cv = (0.3 nm / 500 nm) x (3.00 x 108 m/s) = 1.8 x 106 m/s.
Therefore, velocity of star 1.8 x 106 m/s.

velocity of 1,500 meters per second toward the other whale. How much time did it take the
sound wave to travel from one whale to the other?
Answers
The sound wave took 1.2 seconds to travel from one whale to the other.
Velocity is a physical quantity that describes the rate of change of an object's position with respect to time and includes both the speed and direction of motion. It is a vector quantity, meaning it has both magnitude and direction and is typically measured in meters per second (m/s) or other appropriate units.
The time it took for the sound wave to travel from one whale to the other can be calculated using the formula:
time = distance/velocity
In this case, the distance between the whales is 1,800 meters and the velocity of sound in water is 1,500 meters per second. Therefore:
time = 1,800 meters / 1,500 meters per second

A 19.7 kg sled is pulled with a 42.0 N force at a 43.0° angle, across ground where μ₁ = 0.130.
What is the normal force on the sled?
Answers
The following information is provided in the problem: A sled with a weight of 19.7 kg is pulled with a force of 42.0 N at an angle of 43.0° across ground where μ₁ = 0.130. We need to find out the normal force that is exerted on the sled.
Let us examine each of the forces acting on the sled.The weight of the sled is equal to its mass multiplied by the acceleration due to gravity. Therefore, the weight of the sled is:mg = 19.7 kg x 9.8 m/s² = 193.06 N.The force exerted on the sled can be divided into two components: one that is parallel to the ground and one that is perpendicular to the ground.The force parallel to the ground is:F₁ = 42.0 N x cos(43.0°) = 30.56 N.The force perpendicular to the ground is:F₂ = 42.0 N x sin(43.0°) = 28.30 N.The frictional force is equal to the coefficient of friction multiplied by the normal force. Therefore, we need to find the normal force on the sled in order to calculate the frictional force. Since the sled is not accelerating vertically, the normal force is equal to the weight of the sled plus the force perpendicular to the ground. Therefore, N = mg + F₂N = 193.06 N + 28.30 N = 221.36 N.The frictional force is:Fr = μ₁ x NFr = 0.130 x 221.36 N = 28.77 N.Thus, the normal force exerted on the sled is 221.36 N.For such more question on perpendicular

a) What is the y component of the vector given in the diagram? (120 N, 50 °) 120 N 50⁰ (C) 60 N (B) 92 N (D) 120 N (A) 77N
Answers
Answer: B
Explanation:
The y component of the vector is given by the formula:
y component = magnitude of the vector x sin(angle between the vector and the y-axis)
In this case, the magnitude of the vector is 120 N and the angle between the vector and the y-axis is 50 degrees. So we have:
y component = 120 N x sin(50°) ≈ 92 N
Therefore, the answer is (B) 92 N.
