Block 1, of mass m1 = 3.90 kg , moves along a frictionless air track with speed v1 = 31.0 m/s . It collides with block 2, of mas
Nostrana [21]
The energy would remain equal to that of the initial kinetic energy since it is a frictionless surface. However if it is an inelastic collision then energy would be lost due to sound and heat.

QveST [7]

Explanation:

(1) We have,

Wavelength of a wave is 2 meters

Frequency of a wave is 6 Hz

It is required to find the velocity of a wave. The velocity of a wave is given by :

v=f\lambda\\\\v=2\times 6\\\\v=12\ m/s      

So, the velocity of a wave is 12 m/s.

(2)

Number of waves passing are 100

Time taken to pass the wave is 5 seconds

The frequency of wave is given by total number of waves passing per unit time. So,

f=\dfrac{100}{5}\\\\f=20\ Hz

Frequency of a wave is 20 Hz.

If all else is constant, which would cause the greatest increase in kinetic energy of a moving object?
Maru [420]
When mass is doubled, KE is doubled.
When speed is doubled, KE becomes 4 times as great.
When both are doubled (last choice), KE is multiplied by 8 .
