In the question it is already given that the football player is 80 kg.
Then the mass of the football player = 80 kg
Velocity at which the football player is running = 8 m/s
<span>Kinetic Energy = 0.5 • mass • square of velocity
Now we have to put the known data in this equation to find the actual velocity of the footballer.
</span> <span></span>So
Kinetic Energy of the footballer = 0.5 * 80 * (8 * 8)
= 0.5 * 80 * 64
= 2560
So the Kinetic energy of the footballer is 2560 joules
Answer:
Conductors:Aluminum, copper, car cables
Insulator: rubber, glass
Answer:
Carry energy and momentum ... 10€. Frequency (Hz). Visible Light not to scale). Viclei | Blue Green | Yellow ... An absorbed photon can have an effect on electrons in an atom: ... To convert between eV's and Joules use the conversion (1eV = 1.6x10-19), ... h. 6.63 x 16 34 = 723 x 10Hz. 350. The energy of a photon varies.
Explanation:
i searched it on gogle
At New Moon the percent illuminated is 0; at First and Last Quarters it is 50%; and at Full Moon it is 100%<span>. During the crescent phases the percent illuminated is between 0 and </span>50%<span> and during gibbous phases it is between </span>50%<span> and </span>100%<span>.
so it depends on the phase

Hi,
The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
