Jacob is riding his bike down a tall hill. At the top of the hill, he has 2800J of potential energy. At the bottom of the hill,

when he is going the fastest, his kinetic energy measures 2650J. Which statement below is true? Question 5 options: The total amount of energy at the bottom of the hill cannot equal the amount at the top, because some of the energy is gained. The total amount of energy at the bottom is equal to the amount at the top, but some energy was converted into other forms due to friction. The total amount of energy at the bottom of the hill cannot equal the amount at the top, because some of the energy is destroyed. The total amount of energy at the bottom is equal to the amount at the top, but he gained some energy as he traveled due to a higher speed.

The highest freefall jump on record is from a height of almost 38,000 m. At this height, the acceleration of gravity is slightly
lina2011 [118]

Increasing his acceleration will impact his velocity and rate of displacement covered in that as the speed increases due to the increased rate of acceleration, the rate of air resistance also increases.  

<h3>What is air resistance?</h3>

Air resistance is a force created by air. When an item moves through the air, the force operates in the opposite direction.

When a diver descends, the force of air resistance acts to counteract the force of gravity. As the skydiver falls faster and faster, the quantity of air resistance grows until it equals the magnitude of gravity's force.

A balance of forces is achieved when the force of gravity equals the force of air resistance, and the skydiver no longer accelerates. The skydiver reaches what is known as terminal velocity.

A proton is located at &lt;3 x 10^-10&gt; m. What is r, the vector from the origin to the location of the proton
Eduardwww [97]

Complete Question

A proton is located at <3 x 10^{-10}, -5*10^{-10}  , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton

Answer:

The  vector position is   \=r=

Explanation:

From the question we are told that

  The  position of the proton is m

Generally the vector location of the proton is mathematically represented as

       \= r =

So substituting values

Why do you think the combined wave is more powerful than either the transverse or longitudinal wave with the same amplitude
liq [111]

Answer:

Explanation:

The combined wave only end up been more powerful than the Longitudinal wave. This means, the transverse wave is more powerful than the combined wave. In transverse wave, the oscillation is perpendicular to the direction of the wave, while in longitudinal wave, the motion of the movement of the object is parallel to the movement of the wave. And in combined wave, the movement of the medium is in a circular manner,

The current through a 10 ohm resistor connected to a 120 volt power supply is
Leno4ka [110]

Answer:I=12 A

Explanation:

Given

Resistance R=10 \Omega

Voltage V=120 V

According to ohm's law current through a conductor is directly proportional to the voltage applied.

V\propto I

V=IR

where V=Voltage

I=Current

R=resistance

I=\frac{V}{R}

I=\frac{120}{10}

I=12 A
