Answer: F = 106.72 N
Explanation: <u>Newton's</u> <u>Law</u> <u>of</u> <u>Universal</u> <u>Gravitation</u> states that two masses attract each other by a force pointing in a straight line to the center-of-mass of both masses.
It is directly proportional to the masses and inversely proportional to the square of their distance, represented as:
where
G is gravitational constant whose value is 6.67x10⁻¹¹ N(m/kg)²
m are masses in kg
r is distance in m
The force between the moon and a person with mass of 66kg is:
F = 106.72 N
The force between a person with mass of 66kg and the moon is 106.72 N.
Answer:
The current through the tube is 73.39A.
Explanation:
The relationship between the resistivity , the electric field , and the current density is given by
This equation can be solved for to get:
Since the current is
Now, for the tube of mercury , , and the area is ; therefore,
Hence, the current through the mercury tube is 73.39A.
No.
East-force can only be balanced by west-force.
North-force has no west-force in it, no matter how strong it is.
It is an instrument used to measure blood pressure.
