Arrange the balls in order from greatest amount of gravitational potential energy to least.

Size and weight doesn't matter, Galileo proved this.
All of them have the same potential energy

How much power does it take to move an object with a force of 200 Newton’s a distance of 25 meters and 10 seconds

Work = (force) x (distance)

Work = (200 N) x (25 m)

Work = 5,000 Joules

Power = (work done) / (time to do the work)

Power = (5,000 Joules) / (10 sec)

Power = 500 Joules/sec

Power = 500 watts

Two balls are thrown straight up. the first ball is thrown with twice the initial speed of the second. ignore air resistance. how much higher will the first ball rise?]

Ball 1: h1=U^2/2g Uo=U
ball 2: h2=(2U)^2/2g
4U^2/2g
h2=4h1

A particle is going into a nozzle at 10 m/s and then after 3m the particle is slowing down to 2 m/s. The particle travels through a straight path down the middle of the nozzle. How do you find average acceleration using eularian and then Lagrangian view point.

Explanation:

As we know that the initial speed of the particle when it enters the nozzle is given as

after travelling the distance d = 3 m it will have its final speed as

now we know that when acceleration is constant the equation of kinematics is applicable

so we will have

When ironing clothes, the primary method of heat transfer is

Conduction, since the iron is in direct contact with the clothes.
Heat transfer from a hot iron to a shirt during ironing is an example ofconduction

The right-hand rule predicts the direction of the force on a positively charged object moving in a gravitational field true false

The statement above is FALSE.
The right hand rule is used in physics to predict the direction of the force on a charged object moving in a MAGNETIC FIELD. The right hand rule is used to relate the relationship between the magnetic field and the forces that are exerted on the moving objects in the field. Using the right hand rule, for a positively charged object that is moving in an electric field, the pointer finger will point in the direction the charged object is moving, the middle finger will point in the direction of the magnetic field and the thumb will point in the direction of the magnetic force that is pushing the charged object.

False

Explanation:

The right-hand rule doesn't predicts the direction of the force on a positively charged object moving in a gravitational field true false

What is the difference between linear motion and circular motion?

Linear motion is a movement in a straight path, but circular motion is a motion in a circular path.

PLEASE HELPPPPPP this is really important and I wanna understand it!! It's just too complicated for me... A physics student carries a model rocket from his car 150. m N along a sidewalk and 200. m E into a field to the launch site. He then launches the rocket to an altitude of 500. m. Find the rocket’s distance from the car when it reaches its highest altitude.

559 m

Explanation:

You can use distance formula for 3 dimensions:

d = √((x₂ − x₁)² + (y₂ − y₁)² + (z₂ − z₁)²)

d = √(150² + 200² + 500²)

d ≈ 559

700 is the answer i think
