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.

What are 3 examples of elastic collisions?
Andre45 [30]
QUICK ANSWER

The collision between two gas molecules or billiard balls can be approximated as elastic collisions. Elastic collisions are exchanges of kinetic energy between two bodies having different reference frames in which the total kinetic energy of the two bodies after collision is equal to the energy before collision.'

The substances in the table are combined, and Substance 1 loses 40 calories of heat. How many calories of heat will Substance 2
Luda [366]

Over time, the substances will reach equilibrium, meaning the heat calories lost by Substance 1 will be gained by Substance 2. Therefore, Substance 2 will eventually gain 40 calories of heat.

What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2
Basile [38]

Answer:

\boxed {\boxed {\sf 252.5 \ Newtons }}

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

F=m*a

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

  • m= 50.5 \ kg
  • a= 5.0 \ m/s^2

Substitute the values into the formula.

F= 50.5 \ kg * 5.0 \ m/s^2

Multiply.

F=252.5 \ kg*m/s^2

  • 1 kilogram meter per square second is equal to 1 Newton.
  • Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.

F= 252.5 \ N

The force required is <u>252.5 Newtons</u>.

What is the relationship between power and voltage?
kipiarov [429]

<u>Answer:</u>

The power and voltage are related through Power Rule .

<u> Explanation : </u>

Power Rule  states  that the current I  that flows the element in the circuit  with a loss in voltage V,  then the amount of  power dissipated by that element in the circuit is the   multiplicative product of  voltage and the current.

Mathematically, power law  is

\boldsymbol{P}=\boldsymbol{I} \times \boldsymbol{V}

The rate of work done or the rate of energy consumption or production is  termed as power.Unit of power is denoted as W(watts).

Potential energy between  any two points on a circuit is called as  Voltage and is measured in volts (V) .

Receiver maxima problem. When the receiver moves through one cycle, how many maxima of the standing wave pattern does the receiv
shusha [124]

Answer:

Two.

Explanation:

  • A standing wave or stationary wave are the type of wave in which it oscillates with time but the amplitude does not move.
  • One complete wave consists of two loops.
  • It means that when the receiver moves through one cycle, two maxima of standing wave pattern the receiver pass through.
