A solid of mass 1kg suspended by a string is completely immersed in water. If the tension in the string is 5N, calculate the upthrust on the solid. (take g = 9.78m/s)
I don't understand what you tryna say.
To calculate the upthrust on the solid, we first need to determine the weight of the solid. The weight can be calculated using the formula:
Weight = mass * gravitational acceleration
Given that the mass of the solid is 1kg and the gravitational acceleration is 9.78m/s^2, we can calculate the weight:
Weight = 1kg * 9.78m/s^2 = 9.78N
Since the solid is completely immersed in water, it experiences an upthrust force equal to the weight of the volume of water displaced by the solid. This is known as Archimedes' principle.
The upthrust force is equal to the weight of the water displaced:
Upthrust = Weight of water displaced
Since the mass of the water displaced is equal to the mass of the solid (1kg), we can calculate the weight of the water displaced using the same formula:
Weight of water displaced = mass * gravitational acceleration
Weight of water displaced = 1kg * 9.78m/s^2 = 9.78N
Therefore, the upthrust on the solid is 9.78N.
What is mg-5N ?
tryna? I don't understand.
1*9.78 - 5
Does it really say g = 9.78 m/s and not g = 9.81 m/s^2 ???????
