PLSSSSSSSS SOMEONE HELP ME WITH THIS ONE!!

Answer:

measure what

Explanation:

?????????????

Answer:

B. Mass

Explanation:

Answer: Electrical energy

Explanation:

A power plant is considering an industrial facility that has the ability to generate electricity from its primary energy.

There could be used one or more generator when it comes to power plants and their function is to convert mechanical energy into electrical energy in order to supply power to the electrical grid for other people that are needing electricity and more.

Explanation:

A pendulum should be able to contain enough energy to constantly be moving

Answer:

rock of mass m is dropped to the ground from a height h. A second rock, with mass 2m, is dropped from the same height. When the second rock strikes the ground, what is its kinetic energy? (a) Twice that of the first rock, (b) four times that of the first rock, (c) same as that of the first rock, (d) half as much as that of the first rock, (e) impossible to determine.

If a  rock is dropped into a canyon that is 0.3 km deep, then the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, if a rock is dropped into a canyon that is 0.3 km deep.

By using the second equation of motion given by Newton,

S = ut + 1/2at²

300 = 0 + 0.5 × 9.8 × t²

t² = 300 / 4.9

t = 7.82 seconds

Thus,  the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

Answer:

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 300 × 10

We have the final answer as

Answer:

kinetic is the stored energy being released from being dormant

Explanation:

Answer:

kinetic is the stored energy being released from being dormant

Explanation:

i copied

Answer:

6.58m

Explanation:

The kinetic energy = Workdone on the roller

Workdone = Force * distance

Given

KE = Workdone = 362J

Force = 55N

Required

Distance

Substitute into the formula;

Workdone = Force * distance

362 = 55d

d = 362/55

d = 6.58m

Hence the student must push at a distance of 6.58m

Answer:

Explanation:

The area of the floor covered by his both feet can be found by using the formula

[tex]a = \frac{f}{p} \\ [/tex]

f is the force

p is the pressure

From the question we have

[tex]a = \frac{400}{400} = 1 \\ [/tex]

We have the final answer as

To Find :

Which element accumulates in the environment due to the use of  fertilizers.

Solution :

Most of the fertilizers used in daily practice are nitrogen fertilizers .

When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.

Also, nitrogen is very stable and did not participate in most of the reactions.

So, nitrogen is accumulates in the environment .

Therefore, option C. is correct.

Answer:

average speed - b

speed - d

acceleration- c

Instantaneous speed- a

Explanation:

I think I dont really remember

Answer:

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N

Answer:

Explanation:

The average speed of the car can be found by using the formula

[tex]s = \frac{d}{t} \\ [/tex]

d is the distance

t is the time taken

From the question we have

[tex]s = \frac{300}{6} = 50 \\ [/tex]

We have the final answer as

Hope this helps you

Answer:

50mph

Explanation:

Just do[tex]\frac{300}{6}[/tex] (aka 300 divided by 6)

And you'll get 50 as your answer!

Hope this helps! Ty!

Answer:

28 N

Explanation:

From the question given above, we were told that 10 N force and 18 N force act in the same direction on the object.

The net force acting on the object can be obtained by simply adding both forces together since they both act on the object in the same direction. This is illustrated below:

Force 1 (F₁) = 10 N

Force 2 (F₂) = 18 N

Net force (Fₙ) =?

Fₙ = F₁ + F₂ (since they both act in the same direction)

Fₙ = 10 + 18

Fₙ = 28 N

Therefore, the net force acting on the object is 28 N.

Answer:

A

Explanation:

The material that would best suit Hardin electronic corporation's need would be a non-metal.

Non-metals are naturally occurring substances or materials that lack the properties of metals. In other words, non-metals are poor conductors of heat and electricity, unlike metals.

Solid non-metals are, therefore, used as insulators in the design of materials. Hence, the best material for Hardin electronic corporation to use that will insulate the phone and protect their users from electric shock would be a non-metal.

The correct option is A.

Answer:

it's B

Explanation:

Elastic potential energy is energy stored as a result of applying a force to deform an elastic objects. The energy is stored until the force is removed and the object springs back to it's original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object

Answer: Elastic energy

Answer:

Friction force always acts tangent to the surface at points of contact. Friction force acts opposite to the direction of motion. There are 2 types of friction: Static friction: If the two surfaces in contact do not move relative to each other, one has static friction.
