If you exert a force of 10.0 n to lift a box a distance of 0.9 m how much work do you do

Physics
1 answer:
dalvyx [7]3 years ago
5 0

A bit vague since it's not clear whether the applied force is in the same direction as the box's displacement. But let's assume it is. Then the work done is:

W = Fd

W = work, F = force, d = displacement

Given values:

F = 10.0N, d = 0.9m

Plug in and solve for W:

W = 10.0(0.9)

W = 9J

1.) True or False.
eimsori [14]

Answer:

Explanation:

According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted. 1.True 2.falues 3.true 4. not really sure on this one

List the laws of thermodynamic and describe their relevance in the chemical reactions2. Define the standard reduction potential.
Alenkinab [10]
<h2>Energy remains constant </h2>

Explanation:

Thermodynamic Laws -

  • The primary law, otherwise called the Law of Conservation of Energy, expresses that energy remains constant in the overall reaction, it is not created or destroyed.
  • The second law of thermodynamics expresses that the entropy increases. after the completion of the reaction of any isolated system  
  • The third law of thermodynamics expresses that as the temperature reaches towards an absolute zero point the entropy of a system becomes constant.

Standard Electronic potential  -

  • The standard reduction potential may be defined as the tendency of a chemical species or the reactants to get into its reduced form after the overall reaction.
  • It is estimated at volts.
  • The more is the positive potential the more is the reduction of the chemical species

Aerobic grow is much more efficient at making ATP because of the presence of oxygen the cycles in the respiration are carried out at an efficient rate which forces the cell to undergo a much large amount of ATP production.

Please help 2.
Mariulka [41]

Answer:

The new volume of the balloon is 8.8 L

Explanation:

Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law establishes that the volume is directly proportional to the temperature of the gas, that is to say that if the temperature increases, the volume of the gas increases and that on the contrary if the temperature of the gas decreases, the volume decreases.

In other words, Charles's law states that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:

\frac{V}{T}=k

Having a certain volume of gas V1 that is at a temperature T1, by varying the volume of gas to a new value V2, then the temperature will change to T2, and it will be fulfilled:

\frac{V1}{T1}=\frac{V2}{T2}

In this case:

  • V1= 8.5 L
  • T1= 294 K
  • V2= ?
  • T2= 305 K

Replacing:

\frac{8.5 L}{294 K}=\frac{V2}{305 K}

Solving:

V2=305 K*\frac{8.5 L}{294 K}

V2=8.8 L

<u><em>The new volume of the balloon is 8.8 L</em></u>
