Answer:
Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy. Potential energy is energy an object has because of its position relative to some other object.
Explanation:
Centripetal acceleration is given as
here we know that
v = speed of the car
R = radius of curvature of the car
now here we can see that the acceleration of car directly depends on the square of the speed
so here if speed of the car is tripled then centripetal acceleration will be increased by square times
so here centripetal acceleration is increased by 9 times if speed is tripled
With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
ANSWER:
a) 25.97 N
b) 47.53 N
STEP-BY-STEP EXPLANATION:
Given:
Beaker mass = 1.2 kg
Water mass = 2.5 kg
Water density = 1000 kg/m^3
Block mass = 3.8 kg
Block density = 3300 kg/m^3
a)
The first thing is to calculate the volume of the block, like this:
Mass of water displaced by the block is:
The block will receive a push from the water equal to the weight of the water displaced by the block, or the effective weight of the block will be reduced by the same amount:
Therefore, 25.97 N is the reading on the hanging scale.
b)
The bottom scale will gain by the same amount (1.15 kg). Therefore, the totalweight on the bottom scale is:
Therefore, 47.53 N is the reading on the lower scale.
