Answer:

The gravitational force between these two objects is around $F_{g}=6.674*10^{-11} N$

Explanation:

The gravitational force can be written as:

$F_{g}=G\frac{m_{1}m_{2}}{r^{2}}$

Here:

G is the gravitational constant $G = 6.674*10^{-11} m^{3}kg^{-1}s^{-2}$
m(1) is the first mass
m(2) is the second mass
r is the distance between two bodies.

If we see, the gravitational constant is a very small number, therefore the gravitational force is representative just when we have to massive bodies. Let's suppose that the mass of the pencil is 0.1 kg and the eraser is 0.1 kg too, the distance between them would be around 10 cm or 0.1 m, for instance.

Now let's calculate the gravitational force of these two bodies.

$F_{g}=G\frac{0.01*0.01}{0.1^{2}}$

$F_{g}=6.674*10^{-11} N$

As we see it is very small force, so it is negligible relation to the earth gravitational force. That is why these two objects do not move towards each other.

I hope it helps you!

A glass plate whose index of refraction is 1.66 is immersed in a liquid. The surface of the glass is inclined at an angle of 44º

Anna35 [415]

Answer:

C. 1.15

Explanation:

The formula for the critical angle is:

${sin\theta_{critical}}=\frac {n_r}{n_i}$

Where,

${\theta_{critical}}$ is the critical angle

$n_r$ is the refractive index of the refractive medium. ( Alcohol , ? )

$n_i$ is the refractive index of the incident medium. ( Glass, 1.66 )

<u>Critical angle = 44º</u>

Applying in the formula as:

${sin\theta_{critical}}=\frac {1}{1.523}$

${sin\ 44^0}=\frac {n_r}{1.66}$

${n_r}=1.15$

A bag is dropped from a hovering helicopter. After 42.4s, calculate the bag’s displacement.

Ann [662]

Answer:

8,809.024m

Explanation:

Displacement , y = (gt^2/2 )

g = 9.8 m/s^2

t = 42.4s

y = (9.8 (42.4*42.4)) / 2

y = 8,809.024m
