Answer:
8.0 Ns
Explanation:
Change in momentum is given as:
Final momentum - Initial momentum
= m*v - m*u
Where m = mass of ball
v = final velocity
u = initial velocity
Change in momentum = (2.0 * 3.0) - (2.0 * 7.0)
= 6.0 - 14.0 = -8.0 Ns
The magnitude will be |-8.0| = 8.0 Ns

Answer:
Frequency = 24 × 10⁸ Hz
Explanation:
Given the following data;
Speed = 3 × 10⁸ m/s
Wavelength = 0.125 meters
To find the frequency of the electromagnetic wave;
Mathematically, the speed of a wave is given by the formula;
Speed = Wavelength × frequency
Substituting into the formula, we have;
3 × 10⁸ = 0.125 × frequency
Frequency = (3 × 10⁸)/0.125
Frequency = 24 × 10⁸ Hz
Energy is the capacity to do some type of work
Answer:
b) one-third as great.
Explanation:
As we know that same heat is supplied in this experiment
so we will have

now we know that both are initially at same temperature
then their final temperatures are


now we have

so we have

so heat capacity of mystery metal is 1/3 times that of water
