Answer:
Solar panels
sun light into electricity
Answer: 750Kg
Explanation:
Recall that force is the product of the mass M, of an object moving at a uniform acceleration.
i.e Force = Mass x Acceleration
In this case, Mass = ?
Force = 3.00 x 10^3 N = (3.00 x 1000N)
= 3000N
Uniform acceleration = 4.00m/s^2
Force = Mass x Acceleration
3000N = Mass x 4.00m/s^2
Mass = (3000N/4.00m/s^2)
Mass = 750Kg (The SI unit of mass is kilograms)
Thus, the mass of the car is 750Kg
If the ground is level, then the snowball can never have
any more kinetic energy than it hand when it left your hand.
If more mass sticks to it as it makes its way across the lawn,
then it must slow down, so that its
KE = (1/2) (present mass) (present speed)²
never exceeds the KE you gave it when you tossed it.
And we're not even talking yet about all the energy it loses
by scraping through the snow and mashing down the blades
of grass in its path.
Explanation:
When treating the electron as a wave, the concept of electrons orbiting the nucleus allows for the distinct energy levels.The diameter of electron orbits matches the orbit radii which also discrete the energy levels.
The small number of deflected particles were repelled from powerful heavy positively charged central cores which is known as the atomic nucleus.
