Answer:

B). An unbalanced force is acting on the brick.

Explanation:

Here as we can see the given figure there are two forces acting on the block

1. F_1 = 7,205 N Upwards

2. F_2 = 7,210 N Downwards

so here as we can see that force downwards is more in magnitude while upward force is less.

So here since downward force is more so the box will accelerate downwards and net force is given as

F_{net} = F_2 - F_1

F_{net} = 7210 - 7205 = 5 N

so here net force on this box is 5 N downwards and since there is unbalanced force on the box so box can not remains at rest.

\text{Acceleration}=\frac{d^2}{dt^2}\text{displacement}
So the dimensions of acceleration is LT^{-2}
Any answer that comes under that definition is correct.

1) The energy held in the molecules that your lunch is composed of
Rasek [7]

Answer:

Chemical energy

Explanation:

The energy held in the foods molecules a lunch pack is composed of is chemical energy.

They occur within food substances which originates from plants and animals as giant organic molecules.

  • Since food is often derived from plants and animals.
  • Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
  • Animals takes up these food and build their own body through it.
  • Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
  • When the molecules are broken down, they released their chemical potential energy into heat energy.

krok68 [10]

A car that experiences a deceleration of -41.62 m/s² and comes to a stop after 10.99 m has an initial velocity of 30.60 m/s.

A car experiences a deceleration (a) of -41.62 m/s² and comes to a stop (final velocity = v = 0 m/s) after 10.99 m (s).

We can calculate the initial velocity of the car (u) using the following kinematic equation.

v^{2} = u^{2} + 2as\\\\u = \sqrt[]{v^{2}-2as} = \sqrt[]{(0m/s)^{2}-2(-42.61m/s^{2} )(10.99m)} = 30.60m/s

A car that experiences a deceleration of -41.62 m/s² and comes to a stop after 10.99 m has an initial velocity of 30.60 m/s.
