<span>Kinetic Energy means energy that a body possesses by virtue of being in motion. I hope this helps!!!</span>
Answer:
Plasma
Explanation:
For a fusion reaction to take place, there must be conditions in which the particles have extreme thermal kinetic energies, in this way the collisions that cause the nuclear fusion are generated. Therefore, it is necessary to reach very high temperatures, in which the state of matter will necessarily be plasma.
Answer:
speed is 4/3 × g × sin β
acceleration is g sin θ
Explanation:
Given data
mass = M
radius = R
distance = s
angle = β
to find out
final speed and the acceleration
solution
we know that cylinder is rolling on inclined plane
so from conservation of mechanical energy
energy at top = energy at bottom
energy at top will be
= m ×g×h
= m ×g×s sinβ ................1
and
energy at bottom will be
= 1/2 ×m × v² + 1/2 × z × ω²
= 1/2 ×m × v² + 1/2 × 1/2 ×m× r² × (v/r)²
= 3/4 × v² .................2
equating now equation 1 and 2
m ×g×s sinβ = 3/4 × v²
so v = 4/3 × g × sin β
so speed is 4/3 × g × sin β
and acceleration is
= mg sin θ ............3
and
acceleration = ma ............4
now equation equation 3 and 4
ma = mg sin θ
so acceleration is g sin θ
Answer:
F' = 162 units
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:
where,
F = gravitational force = 18 units
G = Gravitational Constant
m₁ = mass of object 1
m₂ = mass of object 2
r = distance between objects
Therefore,
Now, if we change the value of distance to one-third of original value, then:
r' = r/3
using eqn (1):
F' = 9(18 units)
<u>F' = 162 units</u>
