topjm [15]

90 km per hour = 25 metres per second

a=\frac{v-u}{t}

a=\frac{25-0}{8}

a=3,13m/s^2

Does gravity increase or decrease with greater mass???
xz_007 [3.2K]

Answer:

Increase

As the mass of either object increases, the force of gravitational attraction between them also increases.

Explanation:

The gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.

As the mass of either object increases, the force of gravitational attraction between them also increases.

The two spheres pictured above have equal densities and are subject only to their mutual gravitational attraction. Which of the
kiruha [24]

Answer:

Gravitational force

Explanation:

If two spheres have equal densities and they are subject only to their mutual gravitational attraction. We need to say that the quantities that must have the same magnitude for both spheres. So, the correct option is (E) i.e. gravitational force.

It is because of Newton's third law of motion. It states that the force due to object 1 to object 2 is same as force due to object 2 to object 1. The two forces act in opposite direction.  

Hence, the correct option is (E) "Gravitational force".

How do you determine the acceleration of an object?
Gelneren [198K]

Are you familiar with any basic calculus? If so, we can just look at this derivative and see what's happening with our units here..

a = \frac{dv}{dt}

Here it shows that acceleration is the derivative of velocity with respect to time. In other words, we can say that:

a=\frac{\Delta v}{\Delta t}

We can read that equation as: "acceleration is the change of velocity divided by the change in time (aka the time interval)."

If you're not familiar with calculus, we can use a simple equation of motion:

v_f = v_i+at

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = observed time interval

We can rearrange this equation to find:

a = \frac{v_f - v_i}{t}

This is the same exact thing we wrote before!
