Does a fan that is not spinning have energy?

Answers

Answer 1

Answer:

Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.

Answers

Answer:

It's D

Explanation:

because the kinetic energy of the turbines produces electric energy

The correct answer to the question is D). Kinetic to electrical.
EXPLANATION:
Hydro electric power plants are the electricity generation plants which capture the energy of falling water to produce current.
The water present at the top of a dam has potential energy. When the water is allowed to fall from certain height, the potential energy of the water is converted into kinetic energy.
The falling water moving with high speed is allowed to fall on a turbine. The kinetic energy of the water will rotate the turbine. The turbine is attached to a generator which will produce electricity due to the electromagnetic induction.
Hence, we see that the kinetic energy of the water is converted into electric energy.

When dropped from rest, any object will fall a total distance of 19.6 m in the first 2 seconds of its fall. How far
does the object fall just during the 2nd second (i.e., from time t= 1 s to t = 2 s)?

Answers

Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per

second. Answer B is wrong because velocity increases. Answer C is wrong because the

distance increases every second. Ans. E is wrong because the derivative of distance with

respect to time gives the velocity, not the acceleration.

Explanation:

ecent communication with the inhabitants of Neptune has revealed that they have a Celsius-type temperature scale, but based on the melting point (0oN) and boiling point (100oN) of their most common substance, hydrogen. Further communications have revealed that the Neptunians know about perfect gas behavior and they find that, in the limit of zero pressure, the value of pV is 28 dm3atm at 0oN and 40 dm3atm at 100oN. What is the value of the absolute zero of temperature on their temperature scale

Answers

The absolute zero temperature is the smallest thermodynamic thermal limit, which is considered as a zero kelvin when the enthalpy, as well as the entropy of a cooled ideal gas, are of minimal value.

It is expressed by using the formula:

[tex]\mathbf{T_{abs} = T_N + k}[/tex]

where;

[tex]\mathbf{T_{abs } = absoulte \ temperature}[/tex]

[tex]\mathbf{T_N = temperature \ at \Neptune \ Scale}[/tex]

k = factor to convert temperature from absolute scale to Neptunian scale

N:B: An absolute temperature = zero (0) kelvin

From the information given, Using Ideal gas since it is used in Neptune:

PV = nRT

where;

P = pressureV = volumen = no of molesR = rate(constant)T = temperature

From the question, provided that the gas is the same and no new mass is added;

Then, we can equate the moles of gas in the given conditions as;

[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}....\dfrac{P_nV_n}{T_n}}[/tex]

Using:

[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}}[/tex]

where the value of;

P₁V₁ = 28 dm³ atm

T₁ = 0⁰ N

P₂V₂ = 40dm³ atm

T₂ =  100⁰ N

[tex]\mathbf{\dfrac{28}{(0+K)}=\dfrac{40}{(K+100)}}[/tex]

By cross multiply;

28(K+100) = 40(0+K)

28K + 2800  = 0 + 40K

40K - 28K = 2800

12 K = 2800

K = 2800/12

K = 233.33° N

Recall that:

[tex]\mathbf{T_{abs} = T_N + k}[/tex]

[tex]\mathbf{0= T_N+ 233.33 ^0 N}[/tex]

[tex]\mathbf{ T_N= - 233.33 ^0 N}[/tex]

Therefore, we can conclude that the value of the absolute zero of temperature on their temperature scale is -233.33° N

A projectile is launched vertically with an initial velocity of 50 m/s. How long would it take to reach the top of the launch?

Answers

Answer:

Explanation:

Givens

vi = 50 m/s

vf = 0

a = - 9.81

t = ?

Formula

t = (vf - vi)/a

Solution

t = (0 - 50)/-9.81

t = 5.097

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.

Answer:

It'd take it 5.10 seconds

Explanation:

At the top of the launch, it is maximum height, h

formular derivation :

At maximum height, final velocity, v is zero

From first newtons equation:

[tex]{ \sf{v = u + gt}}[/tex]

v is the final velocity

u is the initial velocity

g is acceleration due to gravity

t is the time taken

but v is zero:

[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]

since it is vertical motion, u = usin(theta), where angle is 90°

[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]

t is the time taken to reach the top of the launch:

substitute, taking g to be 9.8 m/s²

[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]

Is a dog chasing its tail acceleration

Answers

No. A dog chasing its tail is just an animal running around in circles.

The dog's MOTION, however, IS accelerated motion, since the DIRECTION of its motion is constantly changing.

A a dog chasing its tail cannot be considered as acceleration.

What is acceleration?

Acceleration is the rate at which velocity changes over time, both in terms of speed and direction.

A point or object moving in a straight line is accelerated if it accelerates or decelerates. Even if the speed is constant, motion on a circle is accelerated because the direction is constantly changing.

For example, if a car accelerates as it turns a corner at constant speed, it is doing so because its direction is changing.

The faster you turn, the faster you accelerate. When velocity changes in magnitude (increase or decrease in speed), direction, or both, there is an acceleration.

Thus, as there is no change in either speed or direction in scenario in which a dog chases its tail, it is not considered as acceleration.

Four second after starting from rest, what will be the velocity of an object in free fall?

Answers

The velocity of the object in free fall is 39.2 m/s.

Given the following data:

Initial velocity, U = 0 m/s (since the object is starting from rest).Time, t = 4 seconds.

We know that acceleration due to gravity (a) for an object in free fall is equal to 9.8 meter per seconds square.

To find the final velocity (V) of the object, we would use the first equation of motion;

[tex]V = U + at\\\\V = 0 + 9.8(4)[/tex]

Final velocity, V = 39.2 m/s

Therefore, the velocity of the object in free fall is 39.2 m/s.

Answers

Answer:

Explanation:

Well mathematically it would look like this

E = k * I

k is the constant of proportionality.

As the voltage goes up, so does the current.

As the voltage goes down, so does the current.

In physics and engineering,, the formula is written somewhat differently.

E = I * R

The R is a device which limits the current. If R = 0 (like it is just a switch closing) then the first thing you will notice is that the lights go out and you better know where the circuit breakers are and have a flashlight to see which one you shorted out.

So R has a value > 0 in practice.
