Answer:
Light is shown through air on a diamond n=2.42) and it partially reflects and reflects.
Based on the incident angle of 62.5 shown what is the angle of reflection of the light
question of options
21.5
Answer and Explanation:
The law of conversation of energy states that energy cannot be created or destroyed. The pendulum slows down and stops eventually not because the kinetic energy is destroyed, but it is transferred into sound and heat energy instead because there is air resistance and friction.
Kinetic energy => Gravitational potential energy (Loop but some energy transferring to heat and sound each time)
Answer:
you have to substitute the volume of the ballonn with no ruler
Answer:
62m/s
Explanation:
If the object accelerates at a constant rate of 2.5 m/s^2 for 20 seconds, then it will speed up by a total of 2.5*20=50m/s. Adding this to the initial velocity of 12m/s, you get a total velocity of 62m/s. Hope this helps!
