Turbine transformer generator⇆
Answer:
1.4s
Explanation:
Given parameters:
Mass of ball = 2kg
Force = 8N
Time = 0.35s
Unknown:
Change in velocity = ?
Solution:
To solve this problem, we use the expression obtained from Newton's second law of motion which is shown below:
Ft = m(v - u)
So;
Ft = m Δv
F is the force
t is the time
m is the mass
Δv is the change in velocity
8 x 0.35 = 2 x Δv
Δv = 1.4s
PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.
P.E = m * g * h OR P.E. = mgh
m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.
K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.
K.E = 1/2 mv² where m = mass of the body; v = velocity with which the body is moving.
The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. The smaller, inner planets include Mercury, Venus, Earth, and Mars. Inner planet's atmosphere is thin. (Mercury has no atmosphere). Outer Planets: Outer planets' atmosphere is very thick. The four inner planets, Mercury, Venus, Earth, and Mars, are warmer than the outer gas giants. However, the temperature of the planets does not follow a linear path from the Sun.
