luckyme said:the question doesn't say abt surface area. would you work out the upthrust first . don't know volume of water either, don't undstand the componetns.
luckyme said:maybe divide by a cubic meter.
Tension is a force that is exerted on an object by a string, rope, or cable when it is stretched or pulled. It is a pulling force that acts in the direction of the string.
To calculate tension in a string supporting a copper block, you need to know the weight of the block, the acceleration due to gravity, and the angle at which the string is being pulled. The formula for tension is T = m*g*cos(theta), where T is the tension, m is the mass of the block, g is the acceleration due to gravity, and theta is the angle between the string and the horizontal.
Calculating tension in a string is important because it helps determine the strength and stability of the string. It also allows us to understand the forces acting on an object and how they affect its motion. This information is crucial in engineering and physics applications, such as building structures or designing machines.
The weight of an object affects tension in a string because the greater the weight, the greater the force pulling down on the string. This results in a higher tension in the string. In other words, the tension in a string is directly proportional to the weight of the object it is supporting.
No, tension in a string can never be greater than the weight of the object it is supporting. This is because the string can only withstand a certain amount of force before breaking. If the tension exceeds the weight of the object, the string will break and the object will fall.
