Which statement best compares momentum and kinetic energy?

Physics

Answer:

Both variables depend on mass and velocity but momentum is a vector quantity while kinetic energy is a scalar quantity.

Explanation:

Momentum is directly proportional to the mass and velocity. To a greater mass or velocity a greater momentum while Kinetic Energy is inversely proportional to the object's mass. The smaller the mass the greater the Kinetic Energy.

A mass attached to a spring oscillates and completes 53 full cycles in 28 s. What is the time period (in s) and frequency (in Hz
ivann1987 [24]

Explanation:

It is given that, a mass attached to a spring oscillates and completes 53 full cycles in 28 s. Frequency of the system is given by the number of oscillations or vibrations per second. Here, the frequency of this system is given by :

f=\dfrac{no\ of\ oscillations}{time}

f=\dfrac{53}{28}

f = 1.89 Hertz

The relationship between the frequency and the time period of the spring is inverse i.e.

T=\dfrac{1}{f}

T=\dfrac{1}{1.89\ Hz}

T = 0.52 seconds

Hence, this is the required solution.

djverab [1.8K]
Below are the answers:

a. There is a constant magnetic Feld, which means B is constant, so we can rewrite the change in fux as above.Because ΔA is positive, there will be a negative emf in the loop, corresponding to an induced magnetic momentpointing to the left on the page. The current in the loop will be into the page at the top and out of the page at<span>the bottom

</span>V=-Δφ/ Δt = -B·ΔA/ Δ<span>t

b. </span>As the loop’s radius is increasing, we can think about individual electrons in the wire loop as moving radially<span>outward. We’ll consider one in the top of the loop (which is moving up the page). Using the Lorentz ²orce Law

</span>F=q(~v⇥~B)=qvB(ˆy⇥ˆx)=-qvB<span>ˆ

</span>Constant forces pointing into the center of the loop will result in circular orbits (around the wire). Because the<span>force is pointing into the center of the loop, we know we have positive current at that point (into the page).</span>

Cart 1 has an initial velocity and hits cart 2 which is stationary. after a perfectly inelastic collision, the combined carts ar
Tomtit [17]

Option(a)  the mass of cart 2 is twice that of the mass of cart 1 is the right answer.

The mass of cart 2 is twice that of the mass of cart 1  is correct about the mass of cart 2.

Let's demonstrate the issue using variables:

Let,

m1=mass of cart 1

m2=mass of cart 2

v1 = velocity of cart 1 before collision

v2 = velocity of cart 2 before collision

v' = velocity of the carts after collision

Using the conservation of momentum for perfectly inelastic collisions:

m1v1 + m2v2 = (m1 + m2)v'

v2 = 0 because it is stationary

v' = 1/3*v1

m1v1 = (m1+m2)(1/3)(v1)

m1 = 1/3*m1 + 1/3*m2

1/3*m2 = m1 - 1/3*m1

1/3*m2 = 2/3*m1

m2 = 2m1

From this we can conclude that the mass of cart 2 is twice that of the mass of cart 1.
