Thermal energy, radiant energy
Answer:
There are no gaps in space between the photons as they travel.
Yes, you can form the shadow of a fire
Explanation:
Answer:
-273°C = Absolute zero
Explanation:
Average Kinetic energy of particles in matter refers to the temperature of matter. This value is not arbitrary zero temperature. It explains the lowest kinetic energy of the particles in matter.
Answer:
The Moon revolves or moves around the Earth in a path called its orbit and rotates, or spins, in space.
Explanation: The Moon's movements cause the phases of the Moon and the Earth's ocean tides.
Answer:
F = W + ma a> 0
Explanation:
For this exercise let's use Newton's second law
we assume the upward direction as positive
F - W = m a
F = W + ma
F = m (g + a)
In this case they indicate that the speed is less and less as it goes down, therefore the acceleration must be opposite to the speed, that is, the acceleration is upwards, consequently it is positive
We can see that since a> 0 the force F must have greater than the weight of the elevator
