the force of attraction between two masses is 3.60 Newtons if one of the masses is tripled and the distance between the masses is quadrupled what is the new force of attraction
Answers
Answer: F = 19.2 N
Explanation: Given that the initial Force = 3.6N
The formula involved is
F = GMm/r^2
Substitute the force F
3.6 = GMm/r^2
If one of the masses is tripled and the distance between the masses is quadrupled. We have
3.6 = (G × 3Mm)/(4r)^2
Where G will be constant.
3.6 = 3GMm/16r^2
Separate the fraction of number
3.6 = 3/16 × GMm/r^2
Make GMm/r^2 the subject of formula
(3.6 × 16)/3 = GMm/r^2
19.2 = GMm/r^2
Therefore, the new force of attraction is 19.2 N
What do we call the quantity force multiplied by distance

Answer:
When the force is multiplied by the time of its application, we call the quantity impulse, which changes the momentum of that object.Explanation:
Answer:The quantity force multiplied by distance is called work
Explanation:This is because work is the measure of energy in applying force over a certain distance.

How is work related to force and displacement?
Answers
Answer:
Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd. OR Work is a scalar. The rate at which work is done or at which energy is transferred. Work is equal to the force parallel to the displacement.
Explanation:
Work is related to force and displacement as the work is the product of the displacement and the force.
What is work done?The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
The SI unit of work done by an object is Joules.
IJ is the work done when a force of 1 N displaces an object by 1 m .
work is the product of displacement and force.
Work Done = Force * Displacement
For example, let us suppose a force of 100 N is used to displace an object by a displacement of 50 m then the work done on the object can be calculated by the above-mentioned formula
work done = 100 N ×50 m
=5000 N m
Thus, we can say the work done on an object depend on the force as well as the displacement, as the work is the product of the force and the displacement

What is the average velocity of atoms in 1.00 mol of neon (a monatomic gas) at 465 K? For m, use 0.0202 kg.
Answers
Answer: 757m/s
Explanation:
Given the following :
Mole of neon gas = 1.00 mol
Temperature = 465k
Mass = 0.0202kg
Using the ideal gas equation. For calculating the average kinetic energy molecule :
0.5(mv^2) = 3/2 nRt
Where ;
M = mass, V = volume. R = gas constant(8.31 jK-1 mol-1, t = temperature in Kelvin, n = number of moles
Plugging our values
0.5(0.0202 × v^2) = 3/2 (1 × 8.31 × 465)
0.0101 v^2 = 5796.225
v^2 = 5796.225 / 0.0101
v^2 = 573883.66
v = √573883.66
v = 757.55109m/s
v = 757m/s
