Formulae for Kinetic energy is:
Kinetic Energy= 1/2xmassx(velocity)^2
For comparison we need to have same units,thus we convert 10g into Kg.
10g/1000=0.01Kg
Input the value of bullet in the formulae;
Kinetic Energy= 1/2x0.01kgx(400)^2
K.E=800J
Input value of the ball:
Kinetic Energy=1/2x80kgx(6.5)^2
K.E=1690J
Which means that th Energy of the ball is more than the bullet.
Answer:
<em>The first law states that</em> every planet describes an elliptical path about the sun as a single focus.
<em>The</em><em> </em><em>second</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The line joining the planet to the sun sweeps out equal areas in equal time intervals.
<em>The</em><em> </em><em>third</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The squares of the period of revolution is proportional to the cubes of the mean distance between the planet and the sun
Solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels
- Solar power; however provides much more energy than fossil fuel power
- Interestingly too, solar power resource can be used without releasing greenhouse gases compared to fossil fuels power
- Infact, solar energy is the most reliable
<h3>What is renewable energy?</h3>
Renewable energy simply refers to energy that is not depleted when used. An example of such is solar power.
So therefore, solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels

<span>Since frequency and wavelength have inverse relationship. It can be expressed by the equation:
ν.λ = c
Where,
v = frequency of the electromagnetic wave.
λ = it's wavelength
c = the speed of light in a vacuum.
v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz
that means that in one second it covers 2.00 x 10^9 cycles.
λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers</span>
