Heya!!!

Answer to your question:
Gravity is the force of attraction between two objects with mass and is dependent on the distance between these objects.

Formula for gravitational force is: GMm/r^2

where M is the mass of planet, m is the mass of object and r is the distance between them.

Hope it helps ^_^

Gravity is the force of attraction between two objects with mass.
Its strength depends on the mass of both masses, and on the
distance between them.

An object carries a +15.5 µC charge. It is 0.525 m from a -7.25 µC charge. What is the magnitude of the electric force on the ob

lorasvet [3.4K]

Answer:

the force of attraction between the two charges is 3.55 N.

Explanation:

Given;

first charge carried by the object, q₁ = 15.5 µC

second charge carried by the q₂ = -7.25 µC

distance between the two charges, r = 0.525 m

The force of attraction between the two charges is calculated as;

$F = \frac{kq_1q_2}{r^2} \\\\F = \frac{(9\times 10^9)(15\times 10^{-6})(7.25\times 10^{-6})}{(0.525)^2} \\\\F = 3.55 \ N$

Therefore, the force of attraction between the two charges is 3.55 N.

An object of mass 3.4 kg is moving in a straight line with kinetic energy 59.177 J. A force is applied in the direction of its m

rusak2 [61]

Answer:

Its momentum is multiplied by a factor of 1.25

Explanation:

First, we calculate the initial velocity of the object:

K = 0.5 * m * v₁²

59.177 J = 0.5 * 3.4 kg * v₁²

v₁ = 5.9 m/s

With that velocity we can calculate the initial momentum of the object:

p₁ = v₁ * m

p₁ = 20.06 kg·m/s

Then we calculate the velocity of the object once its kinetic energy has increased:

(59.177 J) * 1.57 = 0.5 * 3.4 kg * v₂²

v₂ = 7.4 m/s

And calculate the second momentum of the object:

p₂ = v₂ * m

p₂ = 25.16 kg·m/s

Finally we calculate the factor:

p₂/p₁ = 1.25
