Answer:
The quantities which do not depend on other quantities is called fundamental qiantity. For eg; time,current,lwngth etc...
Answer: Potential energy to kinetic energy
Explanation:
Potential energy is the energy by virtue of its position
P.E = mgh
While
Kinetic energy is the energy by virtue of motion.
K.E = 0.5mv^2
At the top of the hill the boulder has maximum height and thereby possess maximum P.E, as it rolls down the hill the height reduces and velocity increases, so the P.E reduces and K.E increases(P.E is directly proportional to height while K.E is directly proportional to velocity). So as the boulder rolls down the hill its potential energy is converted to kinetic energy (according to the rule of conservation of energy).
The temperature of the Ocean affects weather conditions. Because the Gulf Stream moves warmer water from the North Atlantic towards Europe they actually have warmer winters than other areas do.
Answer:
568.18 N
Explanation:
From the question,
The formula for gravitational potential is given as
Ep = mgh........................ Equation 1
Where Ep = Gravitational potential, m = mass of the diver,h = Height.
But,
W = mg.................... Equation 2
Where W = weight of the diver.
Substitute equation 2 into equation 1
Ep = Wh
Make W the subject of the equation
W = Ep/h................... Equation 3
Given: Ep = 25000 J, h = 44 m
Substitute into equation 3
W = 25000/44
W = 568.18 N.
Hence the weight of the diver = 568.18 N
