Yes, for example a plain is moving so it has kinetic energy, it is also high above the ground so it has gravitational potential energy
<span>F = GMm/r^2
but we don't want force we want acceleration.
F = ma
combining the two
ma = GMm/r^2
cancelling m from both sides
a = GM/r^2
where G is the universal gravitational constant M is the mass of Saturn and r is the radius of Saturn.
g(Saturn) = a = (6.67x10^-11m^3kg^-1s^-2)(5.68x10^26 kg)/(5.82x10^7m)^2
g = 11.18 m/s^2 round to 11.2 m/s^2</span>
Answer: B
White paper reflects some of the incoming waves,
while black absorbs all of the incoming waves.
Explanation:
Light is reflected off of white surfaces. Light is absorbed by opaque materials and transmitted through transparent objects.
In the case of a white paper, a white paper can be considered as a translucent material in which some of the light incident on it bounces off while some pass through it. Therefore, we can conclude that White paper reflects some of the incoming waves,
while black absorbs all of the incoming waves.
When you take a long piece of wire, form it into a coil of several loops, and run a current through it, you get a magnetic field that runs straight along the axis of the coil.
This arrangement of a conductor and the current through it is called a "<em>solenoid</em>". <em>(C) </em>
