Answer:
The distance is 0.9681 m.
Explanation:
Given that,
Length = 0.95 m
Mass of block = 7.9 kg
Stretches spring length = 1.06 m
another mass = 1.3 kg
Magnitude of restoring force acting in the spring equal to the magnitude of applied force
We need to calculate the spring constant
Using Hook's law,
Put the value into the formula
Put the value into the formula
We need to calculate the distance
Using formula of spring constant
Put the value into the formula
We need to calculate the total distance
Using formula of distance
Hence, The distance is 0.9681 m.
Answer:
The amount of heat flows per second in given aluminium bar is 3.066 .
Explanation:
We know that , amount of heat flowing per second is given by
Where A = area =
K = Thermal conductivity =
L = Length =
Upon substituting these values in above equation we get ,
Heat flowing per second =
Answer:
The normal force the ground exerts on the block, F = -300 N
Explanation:
Given data,
The block pulled up with a tension force, T = 100 N
The weight of the block, W = 300 N
The weight of the block is due to the force of attraction of gravitation.
The surface exerts a force that is equal and opposite to the force acting on the block due to gravitation.
The weight of the block,
W = mg
300 N
The normal force the ground exerts on the block,
F = - mg
= - 300 N
Hence, the normal force the ground exerts on the block, F = -300 N
Answer:
A wave is a disturbance that transfers energy from one place to another without requiring any net flow of mass.
Answer:
Explanation:
Assuming the ground is level as well.
F = ma
a = F/m
a = (2000 - 350) / 1500
a = 1.1 m/s²
