Answer: B An action-reaction force pair

Explanation: Took the exam

The arrows in this photograph represent: An action-reaction force pair. Hence, option (B) is correct.

When two bodies interact, they exert an equal and opposite force on one another in accordance with Newton's third law of motion. Action-reaction forces are made up of these forces.

"When one body exerts a force on the other body, the first body experiences a force that is equal in magnitude in the opposite direction of the force which is exerted," according to Newton's third law of motion.

According to the above assertion, there are always two forces operating on the objects involved in an interaction. The forces are of identical magnitude, but the direction of the force acting on the first object is different from the direction acting on the second.

Explanation:

280 x 11 =3,080 J

Answer:

0.78 m

Explanation:

us the formula

speed = frequency x wavelength

343 = 440 x wavelength

343 / 440 = wavelength

wavelength = 0.78 m

I think the last option, you wrote wrongly, it is supposed to be 0.78 not 0.078 .

Boiling a kettle is an example of both thermal and kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object.

Explanation:

Answer:

The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. ... The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill.

Potential energy, also known as energy of position, is a pretty straightforward idea. As the roller coaster rises in the air, gravity has a greater ability to pull it down.

An easy illustration involves a stopped car at the summit of a hill. The car drives faster as it goes down the hill, which results in an increase in kinetic energy and a decrease in potential energy. The vehicle changes kinetic energy into potential energy as it ascends the hill.

They are higher up at the top of the hill, thus they have more potential energy. Moving down a slope transforms potential energy into kinetic energy, while moving up a hill transforms kinetic energy into potential energy.

Therefore, You can release the potential energy you accumulate while climbing a hill as kinetic energy, which is the energy of motion that propels you down the hill.

Answer:

187.5 m/s (i think)

Explanation:

If you use the formula V= T times displacement you can find this out by doing the following-

Displacement equals 75 m

T equals 2.5 hrs

75x2.5= 187.5

and since velocity is measured in m/s, it becomes

187.5 m/s

The basketball's angular velocity ω at time t is

ω = 27 rad/s + (-0.15 rad/s²) t

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

t = (27 rad/s) / (0.15 rad/s²)

t = 180 s

In this time, the ball would undergoes an angular displacement θ of

θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²

Plug in t = 180 s and solve for θ :

θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad

One complete revolution corresponds to a turn of 2π rad, so the ball makes

(2430 rad) / (2π rad/rev) ≈ 386.747 rev

or about 387 revolutions as it slows down.

Answer:

Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.

Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.

The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).

Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.

Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

Answer:A:The track pushes back on Clinton's shoe with the same force.

Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

Momentum is the product of mass and velocity. The two types of momentum are angular and linear.

Explanation:

Answer:

Explanation: (Momentum is mass * velocity. Its units, in the SI system are kilogram meter per second) What is Inertia?

In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.
