Jerome has a tow truck, and he is in charge of moving several vehicles for the city. He wants to explain to his niece how towing vehicles relates to Newton's second law. Which statement should he use?
Answers
Answer:
Force = mass x acceleration
Explanation:
According to the Newton's second law, the net force acting on the object is proportional to the rate of change of momentum of the body.
So, Force is given by
F = m a
where, F is the force, m is the mass and a is the acceleration.
when the mass is more, the acceleration is less as the force applied by the truck is same.
1. Mineral in the earth's crust exists naturally in form of solid elements or compounds *
True
False
Answers
Answer:
True
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Furthermore, the chemical composition (property) of a mineral reflect the presence and arrangement of atoms in each.
Due to the fact that these molecules are structurally arranged (ordered) and are repeated by different symmetrical and translational operations, they determine the shape of minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
Additionally, inorganic-crystalline solid substances which are found naturally within earth are referred to as minerals.
In conclusion, a mineral in the earth's crust exists naturally in form of solid elements or compounds.

Explanation:
4) The net torque on the on the meter stick is equal to zero in order to have no rotation.
[tex]\tau_{1} = \tau_{2}[/tex]
[tex]F_{1}d_{1} = F_{2}d_{2}[/tex]
[tex](8 \:N)(0.3\: m) = F_{2}(0.1 \:m)[/tex]
[tex]F_{2} = \frac{(8 \:N)(0.3 \:m)}{(0.1 \:m)} = 24 \:N[/tex]
5) We are going the same equations in #4 here.
[tex]F_{1}d_{1} = F_{2}d_{2}[/tex]
[tex](500 \:N)(2.4 \:m) = F_{2}(3.0 \:m)[/tex]
[tex]F_{2} = \frac{(500 \:N)(2.4 \:m)}{(3.0 \:m)} = 400 \:N[/tex]
