Answer:

Explanation:

According to Newton's laws of gravitation force of attraction is given by

F = GMm/R²

G = 6.67 X 10⁻¹¹

,M = 2.5 Kg ,

m = 2.5 Kg ,

R = .14 m

=

F = 6.67 X 10⁻¹¹ X 2.5 X 2.5 / 0.14²

= 2126.9 X 10 ⁻¹¹ N.

Answer:

2.13 x 10^-8 N

Explanation:

m1 = 2.5 kg

m2 = 2.5 kg

r = 0.14 m

According to the Newton's law of gravitation, the force of attraction between them is given by

F = G m1 x m2 / r^2

Where, G is the Universal Gravitational constant and the value of G

is 6.67 x 10^-11 Nm^2/kg^2

So, the force between the text books is

F = (6.67 x 10^-11 x 2.5 x 2.5) / (0.14 x 0.14)

F = 2.13 x 10^-8 N

An object sits at rest at some position to the left of the origin. Draw what you expect the position vs time, velocity vs time,
Andru [333]

Answer:

  see below

Explanation:

The position graph will be a horizontal line (of constant position) located at the negative value representing the position to the left of the origin.

The velocity graph will be a horizontal line at 0, since the object is at rest.

The acceleration graph will be a horizontal line at 0, since the object's velocity is not changing.
