Which form of energy is involved in weighing fruit on a spring scale?
2 answers:
Answer:
d. gravitational potential energy and elastic potential energy
Explanation:
when fruits are weighed on the weighing scale using spring balance then the spring is stretched due to weight of the fruits
So here if the spring comes to rest just by stretching the spring by some amount of "x"
So here in that case we can say that the object will go down by same amount that is the amount of spring stretch
Now the gravitational potential energy of the spring will decrease as the height decreases and the same amount of spring potential energy will increase in that case.
So here we can say
loss in the gravitational potential energy = gain in the spring potential energy

First, let's put 22 km/h in m/s:
Now the radial force required to keep an object of mass m, moving in circular motion around a radius R, is given by
The force of friction is given by the normal force (here, just the weight, mg) times the static coefficient of friction:
Notice we don't use the kinetic coefficient even though the bike is moving. This is because when the tires meet the road they are momentarily stationary with the road surface. Otherwise the bike is skidding.
Now set these equal, since friction is the only thing providing the ability to accelerate (turn) without skidding off the road in a line tangent to the curve:
