Which set of terms best defines what affects kinetic energy to potential energy, respectively?

Answers

Answer 1

Answer:

Velocity and height are the terms that best describes what affects kinetic energy and potential energy.

Answer 2

Answer:

By definition, the kinetic energy is given by:

Where,

m: body mass

v: body speed

On the other hand, the potential energy is:

Where,

m: body mass

g: acceleration of gravity

h: height of the object

Therefore, a set of terms that affects kinetic and potential energy are speed and height, respectively.

Answer:

The set of terms is speed and height, respectively.

Answers

The term that describes a wave energy from the choice is periodic. Wave energy occurs at intervals thus periodic. The main properties of a wave energy are the amplitude, wavelength, frequency and speed. Also, period is a property where it is defined as the time it takes for one complete wave to pass a certain point.

Answer:

periodic

Explanation:

When preparing for a rocket launch, the mission control center uses the phrase "T minus" before liftoff. ...T minus 3, T minus 2, T minus 1, ... After the rocket has launched, "T plus" is used while the rocket is in flight. ...T plus 1, T plus 2, T plus 3, ... When does the rocket launch? What does "T" represent?

Answers

The rocket launches when the countdown reaches "T minus 0." "T" represents the time remaining until a specific event.

What does "T" symbolize in rocket launch countdowns?

In the context of rocket launches, "T" represents time. The countdown begins with "T minus" indicating the time remaining until liftoff. As the countdown progresses, the value of "T" decreases, counting down to zero, which marks the exact moment of launch.

Once the rocket is airborne, the countdown transitions to "T plus," denoting the time elapsed since liftoff. This standardized countdown terminology allows mission control to communicate crucial timing information precisely and efficiently during various phases of the rocket's journey.

The source of the centripetal force required for a car to round a curve is friction, I believe. This would be because the cars wheels are grinding across the ground while rounding a curve. It's not Tension, because the stretching of the wheels don't really help and although gravity/weight make the car stay on the ground, it's the fricition that makes it round a curve.

The Correct Answer Is Friction.

Answer:

Reproducibility

Explanation:

The results of an experiment should be reproducible. By repeating the experiment several times, a confidence interval can be determined that will help establish that the results are real, and not an artefact

A rock at the top of a 30 meter cliff has a mass of 25 kg. Calculate the rock’s gravitational potential energy when dropped off the cliff. Assuming that energy is conserved and there is no air friction and gravity is 9.8 m/sec., at the bottom of the cliff the rock’s potential energy is completely converted to kinetic energy. Use the formula for kinetic energy to calculate the rock’s speed at the bottom of the cliff. Show all calculations.

Answers

Potential energy =

   (mass) x (gravity) x (height above the reference level) .

Relative to the bottom of the cliff, the potential energy
at the top of the cliff is

   (25kg) x (9.8 m/s²) x (30 meters)

   = (25 x 9.8 x 30) kg-m²/s²

   = 7,350 joules .

Kinetic energy = (1/2) x (mass) x (speed²)

The rock's kinetic energy at the bottom is
the same as its potential energy at the top.

7,350 joules = (1/2) x (25 kg) x (speed²)

Divide each side
by 12.5kg : 7,350 joules/12.5 kg = speed²

   7,350 kg-m²/s² / 12.5kg = speed²

   (7,350 / 12.5) m²/s² = speed²

      588 m²/s² = speed²
Take the square root
of each side:
   Speed = √(588 m²/s²)

   = 24.248... m/s (rounded)

Lets see:-

We have our formula for potential energy, which we are trying to solve for,

PE = mgh or potential energy = mass * gravity * height

So we know that PE all depends on these.

Height : 30 meters
Mass : 25 kg
Gravity (which is always constant) : 9.8 m/s/s

Now add into formula.

PE = 25*30*9.8
PE = 7350 Joules

Answer: PE = 7350 Joules
