use the formula
v= u+ at
v is final velocity , u is initial velocity , a is acceleration and t is time
put the values
20 = 0+ a×5
a = 4 m/s²
In the modern atomic model the number of electrons in a neutral atom is the same as the number of protons.
An atom contain, three fundamental particles, electron, proton, and neutron, neutron is charge less, there the charge of the atom is determined by the number of proton, and number of electron, Atoms are electrically neutral, it is only possible when number of electrons in an atom is equal to the number of proton.
Kepler actually showed that the planets move around the sun in ellipses, not circles. So the answer is false.
Answer:
132 W
Explanation:
Efficiency = power out of generator / power into generator
0.6 = P / 220 W
P = 132 W
