Potential energy is the energy an object has because of its __________.

Physics
1 answer:
jasenka [17]3 years ago
4 0

Answer:

option D

Explanation:                                    

The correct answer is option D  

Potential energy of an object is because of its location.

 Expression of potential energy      

     P E = m g H                                  

where H is the height of the object.            

           g is acceleration due to gravity, 9.8 m/s²

           m  is the mass of the object.          

Potential energy is directly proportional to the location of the object.    

If the height of the object is more than the potential energy of the object will also increase.

Why does the cyclist have less kinetic energy at position A than at position B?
Semmy [17]
Suppose that the cyclist begins his journey from the rest from the top of a wedge with a slope of a degree above the horizontal.
 At point A (where it starts its journey), the energy is:
 Ea = m * g * h
 In other words, energy is only potential.
 At point B (located at the bottom of the wedge), the energy is:
 Eb = (1/2) * (m) * (v ^ 2)
 In other words, the energy is only kinetic.
 For energy conservation we have:
 Ea = Eb
 That is, we have that all potential energy is transformed into kinetic energy.
 Which means that the cyclist has less kinetic energy at point A because that's where he has more potential energy.
 answer:
 the cyclist has less kinetic energy at point A because that's where he has more potential energy.

Electric resistance ____________ with a(n) ____________in the length of a wire and as a result current flow ___________.
maria [59]
The answer is D. Electric resistance increases with an increase in the length of a wire and as a result current flow decreases. There is a direct relationship between the length of the wire and the resistance. The longer the wire, the more resistance there will be. Additionally, from Ohm's Law, current is inversely proportional to resistance. This means as the current increases, resistance decreases or vice versa.

What are possible formulas for impulse? Check all that apply. J = Fdeltat J = StartFraction force over change in time EndFractio
Alex

<u>The possible formulas for impulse are as follows:</u>

J = FΔt

J = mΔv

J = Δp

Answer: Option  A, E and F

<u>Explanation:</u>

The quantity which explains the consequences of a overall force acting on an object (moving force) is known as impulse. It is symbolised as J. When the average overall force acting on an object than such products are formed and in given duration than the start fraction force over change in time end fraction J = FΔt.

The impulse-momentum theorem explains that the variation in momentum of an object is same as the impulse applied to it: J = Δp J = mΔv if mass is constant J = m dv + v dm if mass changes. Logically, the impulse-momentum theorem is equivalent to Newton second laws of motion which is also called as force law.
