A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a forceA)of zero
b) of less than 600 N is the truck is slowing down
c) equal to 600 N only if the truck is moving at constant velocity
d) equal to 600 N no matter what the acceleration of the truck
e) greater than 600 N if the truck is accelerating

Answers

Answer 1

Answer:

A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force equal to 600 N no matter what the acceleration of the truck. Option c is correct.

What is Newton's third law of motion?

According to Newton's third law of motion, every action has an equal and opposite reaction. As well as the action and reaction are always acted in pairs.

Based on the law of action-reaction,

A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force greater than 600 N if the truck is accelerating.

If the truck is moving at constant velocity the acceleration is zero resulting in no force exerted by the truck on the trailer

The force by which the transport truck pulls on a trailer is equal to the force by which the trailer pulls the truck.

F₁ is the force by which the transport truck pulls on a trailer

F₂ is the force by which the trailer pulls the truck

F₁=F₂

A 600N [E] pulling force is applied by a transport vehicle to a trailer. Regardless of the transport truck's acceleration, the trailer pulls on it with a force of 600 N.

A soccer player kicks a ball with a speed of 30 m/s at an angle of 10. How long does the ball stay in the air?

Answers

"10" is not a very satisfying description of an angle.
I'll assume it's 10 degrees, and that it's the angle of the initial trajectory
above the horizontal.

The vertical component of the ball's speed is 30 sin(10°) = 5.209 meters per second.

The acceleration of gravity is 9.8 meters per second² downward.

The ball continues to rise for 9.8/5.209 = 1.881 seconds after the kick.
At that time, it reaches the peak of its arc, and if nobody else has contacted it yet,
it begins to fall, and takes the same length of time to return to the ground whence
it was kicked.

So the time between the kick and return to the ground is (2 x 1.881) = 3.763 seconds.

Note: As is customary and necessary at the high school level,
we assume no air resistance.

The picture above shows 3 sets of balloons, all with a particular charge. Which of the picture(s) is true? Explain. Then explain why the other 2 pictures are incorrect. Make sure to explain all 3 sets.

Answers

Among all of the others Picture 3 is correct.

We know, Like charges repel each other whereas unlike charges attract each other, In picture 3 they are like charges (both are positive) so, we can repulsion hence, picture is correct!

In picture 1, they are unlike charges, & showing repulsion which is wrong, same In picture 2, they are like charges & showing attraction so they are wrong as well

A proton moves along the x axis according to the equation x = 38 t + 14 t2, where x is in meters and t is in seconds. Calculate (a) the average velocity of the proton during the first 3.0 s of its motion, (b) the instantaneous velocity of the proton at t = 3.0 s, and (c) the instantaneous acceleration of the proton at t = 3.0 s.

Answers

Answer:

a) 240 m

b) 122 m/s

c) 28 m/s²

Explanation:

Given:

Equation for motion

x = 38t + 14t²

a) average velocity during first 3 seconds

average velocity = $\frac{\textup{change in displacement}}{\textup{cahnge in time}}$

now,

distance, at t = 0 s

x = 38 × 0 + 14 × 0² = 0 m

distance, at t = 3 s

x = 38 × 3 + 14 × 3² = 240 m

therefore,

average velocity = $(240-0)/(3-0)$ = 80 m/s

b) instantaneous velocity of the proton at t = 3.0 s

Instantaneous velocity, v = $(dx)/(dt)=38+28* t$

Instantaneous velocity, v = $(dx)/(dt)=38+28* 3$

= 122 m/s

c) instantaneous acceleration of the proton at t = 3.0 s

Now,

Acceleration = $(dv)/(dt)$ = 0 + 28 = 28 m/s²

How does an antenna’s receiving circuit select electromagnetic radio waves of a certain frequency and reject all others?

Answers

An antenna’s receiving circuit select electromagnetic radio waves of a certain frequency and reject all others. This is because an antenna IS an electromagnetic radiator that creates an electromagnetic field that scatters from the transmitting antenna to the receiver’s antenna.
