Answer:
speed up
Explanation:
it's sound, not electromagnetic
Answer:
More than two million electron volts.
Explanation:
More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
Answer:
c. the hole in the plate and the opening in the ring get larger.
Explanation:
The hole in the plate and the ring both of them get enlarged.
The thermal expansion is very much similar to the optical expansion of the shadow of an object.
<em>The change in length of an object is given by the relation:</em>

where:
l = original length of the object
coefficient of linear expansion
ΔT = change in temperature
frequency of engine is given here




now we have angular speed as


similarly


now by the formula of angular acceleration we will have




Answer:
option (e) is correct.
Explanation:
mass of adult, M = 81 kg
Gravitational Potential energy of adult, U = 2000 J
Let the height raised is h.
U = mass of adult x g x h
2000 = 81 x 9.8 x h
h = 2.52 m
mass of adult, m = 18 kg
height raised, h = 2.52 m
Potential energy of child, U' = m x g x h
U' = 18 x 2.52 x 9.8 = 444.44 J
Thus, option (e) is correct.
