Answer:
<em>The statement is true</em>
Explanation:
<u>Energy Conversion
</u>
When an object starts to fall in free air, it speeds up as it falls. The force of gravity acting on the object causes energy to be transferred from its gravitational potential energy to its kinetic energy. We can safely say the height converts to speed and vice-versa. If no external forces act on the system, we can easily calculate heights and speeds by knowing the total mechanical energy (gravitational potential plus kinetic) is conserved.
Answer:
Answer:
After one half of the battery's useful life.
Explanation:
Batteries of the emergency locator transmitter (ELT) must be replaced or recharged after one half of the battery's useful life because if it is exposed to the high temperature for a long period of time such as the air plane parked in the sun will result in the deterioration of battery which may makes the transmitter out of order before the expiry date of the battery. So it will be safe to do that after the use of one half of the battery's life.
Answer:
Newton's first law
Explanation:
it says that an object will continue to be at rest or keep moving till any external for is applied to it to make it move or stop respectively.
Answer:
Explanation:
masie m = 20g = 20/1000 = 0.02kg
prędkość v = 50m/s
P.E = K.E = ½mv²
P.E = ½ × 0.02 × 50²
P.E = 25 J
pracę wykonana = P.E = 25J
