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.
I think the gravity doesn't affect the mass of an object. Only it's weight can be compared
Answer:
Explanation:
In our universe the unit of current used to be defined as the current that produces a certain force per unit of length between two wires separated by a certain length. This means:
Replacing force by its definition
And since current is charge over time
From this we can define length as a function of time, mass, and charge:
Constant speed along the inclined surface = 30 m / 4 s = 7.5 m/s
Vertical speed = inclined speed * sin(45) = 7.5 *√2 / 2 = 5.3 m/s
Answer: 5.3 m/s
