Answer:
W =1562.53 N
Explanation:
It is given that,
Radius of the aluminium ball, r = 24 cm = 0.24 m
The density of Aluminium,
We need to find the thrust and the force. The mass of the liquid displaced is given by :
V is volume
Weight of the displaced liquid
W = mg
So,
So, the thrust and the force is 1562.53 N.
Answer: The current must be equal to amps, or ~0.9574 amps.
Explanation:
You can find the current in amperes using ohms and watts from this formula:
Where P represents power in watts, R represents resistance in ohms, and I represents current in amperes.
You can then substitute 60 and 55 into the equation to find I:
Then, simplify the denominator:
Rationalize the denominator:
Simplify the numerator by finding its factors:
The current must be equal to amps, or ~0.9574 amps.
