Is proportional to the value of the normal force acting on the object.
The answer is A : 302 I really hope this helps!
Answer:
(C) T
The tension T at equilibrium will be equal to the Buoyant force.
The Buoyant force is given by:
Fb = density x acceleration due to gravity x volume displaced
The change in height doesn't affect the Buoyant force and hence the tension.
Note: The figure of question is added in the attachment
Coal is burned and is used to boil water, which in turn produces steam. Now this steam is passed through nozzles. The steam turns a steam turbine. Now the turbine is coupled to a generator. Generator is an electro magnetic device used for conversion of mechanical energy into electrical energy. So in the generator a voltage difference is created and converted into electrical.
Hope this help : )
But the fact is that an accelerating object is an object that is changing it’s velocity.. for this reason , it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing .
