C. Newton’s Third Law of Motion.

Because...
Newtons third law implies conversation of momentum it can also be seen as following from the second law: when one object pushes a second object at some point of contact using an applied force, there must be an equation of opposite force from the second object that cancels the applied force. Otherwise, there would be a nonzero net force on a massless point which, by the second law, would accelerate the point of contact by an infinite amount.

If a planet has a radius 20% greater than that of the Earth but has the same mass as the Earth, what is the acceleration due to

Vaselesa [24]

Answer:

$g_2=6.8125 m^2/sec$

Explanation:

We know that

Acceleration due to gravity g is given by the formula

$g= \frac{GM}{r^2}$

G= gravitational constant

M= mass of the Earth

r= radius of the earth

$g_1 = GM/r_1^2$

Let acc. due to gravity after radius is 20% greater be g_2

then

$g_2=GM/r_2^2$

=> g1/g2 = (r_2/r_1)^2 => g2 = 9.81/1.2^2 = 6.8125

A piece of plastic with a mass of 15 g is

satela [25.4K]

Answer:

The density of plastic is equal to 0.6 g/mL.

Explanation:

Given that,

The mass of piece of plastic, m = 15 g

It is placed in a graduated cylinder. The water level in the graduated cylinder rises from 30 mL to 55 mL when the plastic is added.

We need to find the density of plastic.

Rise in volume = 55 mL - 30 mL

= 25 mL

The density of an object is given by :

$d=\dfrac{m}{V}\\\\d=\dfrac{15\ g}{25\ mL}\\\\d=0.6\ g/mL$

So, the density of plastic is equal to 0.6 g/mL.

Why can you get a shock if you touch a metal doorknob after walking across a wool carpet? (1 Point) You have gained electrons; t

GenaCL600 [577]

Why can you get a shock if you touch a metal doorknob after walking across a wool carpet is because you have gained neutrons; the doorknob has fewer electrons. This is further explained below.

<h3>What are electrons?</h3>

Electrons can be defined as a stable subatomic particles with a negative electrical charge that is found in all atoms and serves as the major carrier of electricity in solids.

In conclusion, You have an unbalanced charge, while the doorknob is neutral. you have gained neutrons; the doorknob has fewer electrons.
