The frequency of oscillation of the wave emit- ted by an FM radio station is 88.7 MHz.
Find the period of vibration. Radio waves travel at a speed of light; 3 × 108 m/s.
Answer in units of ns.

Explanation:

Period = 1 / frequency

T = 1 / (88.7×10⁶ Hz)

T = 11.3×10⁻⁹ s

T = 11.3 ns

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
