A 34.0 %-efficient electric power plant produces 800 MW of electric power and discharges waste heat into 20∘C ocean water. Suppo

se the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. A typical American house requires an average 20kW for heating.
How many homes could be heated with the waste heat of this onepower plant?

Answer:

77647

Explanation:

\eta = Efficiency = 34%

Power used in 1 home = 0.02 MW

Total power is

P=\dfrac{800}{\eta}\\\Rightarrow P=\dfrac{800}{0.34}\\\Rightarrow P=2352.94117\ MW

Waste of power

2352.94117-800=1552.94117\ W

Number of homes would be given by

n=\dfrac{1552.94117}{0.02}=77647.0585\ homes

The number of homes that could be heated with the waste heat of this one power plant is 77647

a 7.26kg bowling ball (16 pounds) is at rest at the end of the bowling lane. : how long did you push the ball in this situation
nlexa [21]

Let F be the force acting on the bowling ball.

Work done by force= change in KE

Let F be the force acting on the bowling ball

Work done by force = change in KE

F .d = 0.5 m V^2 + 0.5 x I x w^2

F d = 0.5 m ( 1+l) V^2

Solve accordingly to get the answer.

A block is at rest on the incline shown in the figure. The coefficients of static and ki- netic friction are μs = 0.62 and μk =
GREYUIT [131]

The frictional force is 218.6 N

Explanation:

The block in the problem is at rest along the inclined surface: this means that the net force acting along the direction parallel to the incline must be zero.

There are two forces acting along this direction:

- The component of the weight parallel to the incline, downward along the plane, of magnitude

mg sin \theta

where

m = 46 kg is the mass

g=9.8 m/s^2 is the acceleration of gravity

\theta=29^{\circ} is the angle of the incline

- The (static) frictional force, acting upward, of magnitude F_f

Since the block is in equilibrium, we can write

mg sin \theta - F_f = 0

And substituting, we find the force of friction:

F_f = mg sin \theta = (46)(9.8)(sin 29^{\circ})=218.6 N

Define quant......am physics​
Bas_tet [7]

Answer:

<h2><u>✍</u><u> </u><u>What is quantum physics?</u></h2>

  • ➳ It's the physics that explains how everything works; the best description we have of the nature of the particles that make up matter and the forces with which they interact.
  • Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.

<h2>ANSWER: </h2><h2>_____________________________________</h2><h2>TYPES OF CHEMICAL REACTIONS:</h2>

There are two types of Reactions,

<h3>Endothermic Reactions: </h3>

Endothermic reactions are the type chemical reaction in which the reactants absorb heat energy from the surroundings. The energy of reactants is more than the energy of product

<h3>Exothermic Reactions: </h3>

Exothermic reactions are the type of chemical reactions in which release of energy takes place in the form of heat or light. In an exothermic reaction, energy is released. The energy of the products is less than the energy of the reactants.

<h2>_____________________________________</h2><h3 /><h3>In Question number 5,</h3>

The key word is "RELEASE". The reaction in which energy is released is the Exothermic reaction thus the Option B that is EXOTHERMIC REACTION is correct.

<h2>_____________________________________</h2><h3 /><h3>In Question number 6</h3>

It is asking that which process stores the energy that means it is asking which process undergoes endothermic reaction. The answer is Option C that is PHOTOSYNTHESIS is correct.

<h3>__________________________________________________</h3><h3>WHY PHOTOSYNTHESIS?</h3>

Because, sunlight is being absorbed during the reaction and according to the definition of endothermic reaction if heat is being absorbed it is termed as an endothermic reaction.
