This question involves the concepts of tension, weight, and centripetal force.
The maximum speed, the mass can have before the string breaks is "10.26 m/s".
First, we will find the maximum tension force:
Tension = Weight
T = W = mg = (32.4 kg)(9.81 m/s²)
T = 317.84 N
Now, this tension force must be equal to the centripetal force:
where,
v = maximum speed = ?
r = radius = 1.21 m
m = mass = 3.65 kg
Therefore,
<u>v = 10.26 m/s</u>

The attached picture shows the centripetal force.
Answer: multiply mass and acceleration, unit is N (newtons)
Explanation: law of dynamics: F = ma
Answer:
Explanation:
Given
Mass of big box is M and small box is m
Tension T will cause the boxes to accelerate
where a=acceleration of the boxes
Now smaller box will slip over large box if the acceleration force will exceed the static friction
i.e. for limiting value
thus maximum tension
Geothermal energy.
Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made.
I hope this answer and these explanations helped!
Explanation:
For this problem, use the first law of thermodynamics. The change in energy equals the increase in heat energy minus the work done.
ΔU=Q−W
We are not given a value for work, but we can solve for it using the force and distance. Work is the product of force and displacement.
W=FΔx
W=3N×2m
W=6J
Now that we have the value of work done and the value for heat added, we can solve for the total change in energy.
ΔU=Q−W
ΔU=10J−6J
ΔU=4J
Answer is 4J
i think this may help you very much
