They both are objects u can get chocked by
Electric current is a stream of electrons in motion, so they have to gain an energy from outside. There are two possibilities: one of them is the photoeletric phenomenom which is based on striking electrons from their orbits with the photon's energy. Second options is the substraction od eletric potentials on the edges od material.
Answer:
radiation reaches the earth it must be absorbed by the different living organisms and when using part of its energy is transformed into radiation of greater wavelength (lower energy) that is irradiated by these organisms; This infrared radiation is absorbed by different gases in the atmosphere
Explanation:
The radiation that comes from the Sun has all wavelengths, due to the 5500K sun temperature its maximum emission is 550 nm (green), when this radiation reaches the earth it must be absorbed by the different living organisms and when using part of its energy is transformed into radiation of greater wavelength (lower energy) that is irradiated by these organisms; This infrared radiation is absorbed by different gases in the atmosphere and cannot escape, creating the so-called greenhouse effect.
If the initial wavelength does not change, it would be emitted into space whereby such temperature of the planet will decrease significantly
Answer:
0.5m
Explanation:
1m = 100cm 1×100 will give that answer so in converting 50cm into m you just need to do it vice versa ÷100 that will give you your answer which is 0.5m
The relevant equation we can use in this problem is:
h = v0 t + 0.5 g t^2
where h is height, v0 is initial velocity, t is time, g is
gravity
Since it was stated that the rock was drop, so it was free
fall and v0 = 0, therefore:
h = 0 + 0.5 * 9.81 m/s^2 * (4.9 s)^2
<span>h = 117.77 m</span>
