Answer:

The direction of the resulting force on this current is due east.

Explanation:

Given;

direction of the magnetic field to be due north

Applying right hand rule which states that: to determine the direction of the magnetic force on a positive moving charge point the thumb of the right hand in the direction of velocity v, the fingers in the direction of magnetic field B, and a perpendicular to the palm points in the direction of magnetic force.

Since the magnetic force must be perpendicular to the magnetic field, and direction of the magnetic field is due north, then the magnetic force must be due East.

Therefore, the direction of the resulting force on this current is due east.

yaroslaw [1]

Answer:

The astronaut's acceleration is 155.1 times the vehicle's acceleration

Explanation:

These effects due to Newton's third law of action and reaction. Since the forces are equal but in the opposite direction and each acting on a different body. We distance that the Force is F let's calculate the acceleration of the vehicle and the astronaut  

Astronaut

        F = m_{ast}  a₁

Vehicle

        F = m_{veh} a₁

F = 555.1 m_{ast} a₂

Let's match the equation

m_{ast} a₁ = 155.1 m_{ast} a₂

a₁ = 155.1 a₂

a₁ / a₂ = 155.1

The astronaut's acceleration is 155.1 times the vehicle's acceleration

We see that even when the acceleration of the vehicle is small, there is a very high multiplicative factor.

One method to improve this situation is that the vehicles fear some small retro-rocket vehicles to reduce their acceleration. This would have a very favorable impact on the astronaut's mission.

Another method would be for the astronaut himself to have the retro-rocket and control his acceleration.

A 500 kilogram marlin and a 20 kilogram salmon are swimming at the same velocity. How does the momentum of the two fish compare?
ElenaW [278]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Below are the choices that can be found from other sources:

A. The marlin has more momentum. 

<span>B. The salmon has more momentum. </span>

<span>C. Both have the same momentum. </span>

<span>D. Both have no momentum.
</span>
Velocity is speed. Momentum is the product of velocity and mass. Because the Marlin has a much greater mass that means that it's momentum would also be greater. 

<span>Lets look at this. momentum = mass x velocity </span>

<span>lets say that velocity for both fish is at 2 meters per second </span>
<span>Marlin : momentum = 500 x 2 = 1000 </span>
<span>Salmon : momentum = 20 x 2 = 40 </span>

<span>Therefore the answer is A</span>

A rebuttal that Rousseau would use to counter the King’s argument?
ankoles [38]

Is this your Question:

Read the hypothetical situation below and answer the question that follows.

In response to criticisms that the King of Mordor has failed to gain the consent of his people, the King claims that he does in fact represent the consent of the people because without their King, society would crumble into chaos.

Which statement BEST represents a rebuttal that Rousseau would use to counter the King's argument?

A. Absolute chaos is preferable to the absolute power of the King.

B. The King of Mordor should establish a system of checks and balances.

C. If the King of Mordor were to represent the will of his people, then he would at least provide the public services demanded by his people.

D. It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.

If this is your question.. Here is your Answer:

Answer:  D. It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.

Explanation:

Rousseau believed that sovereignty (the power to make laws) belonged to the people, not one person, and that it should be carried out by a representative body of the people who are elected by them on their behalf. While he agreed society requires a ruler(s), he thinks they should be chosen by the people.

Is mass on a ramp related to acceleration?
Verdich [7]
Yes it may or may not be depending  on the angle of the ramp. But if nothing is specified then it must be related to acceleration as friction is neglected.
