Write Newton's 3rd law. How would this law relate to a rocket ship taking off from the earth? Would this law affect the rocket s
irina1246 [14]

Answer:

Part A

Newton's 3rd law states that action and reaction are equal and opposite, mathematically, we have;

F_A = -F_B

Where;

F_A = The action force

F_B = The reaction force

Part B

The law indicates that the force with which a rocket ship uses in taking off from the Earth, F_A is equal in magnitude, and opposite in direction to the reaction force of the Earth to the motion of the rocket, (-)F_B

Part C

The law is a universal law, and it will also affect the rocket ship in space, as the force of the jet from the exhaust is directed towards Earth while in space, the rocket is propelled deeper into space

What is the net force on a car moving in a straight line with a constant velocity
guapka [62]

Answer:

For example, when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts. The resultant force on the car is zero.

An electron travels through a particular point in an experimental apparatus with a velocity of 0.949 \times 10^6×10 ​6 ​​ m/s an
Rzqust [24]

Answer:

The magnitude of the acceleration of the electron at this point is 3.94\times10^{14}\ m/s^2.

Explanation:

Given that,  

Velocity v= 0.949\times10^{6}\ m/s

Angle = 61.5°

Magnetic field = 0.01 T

We need to calculate the magnetic force

Using formula of magnetic force

F=Bev\cos\theta

Where, B = magnetic field

v = velocity

e = charge of electron

Put the value into the formula

F=0.01\times1.6\times10^{-19}\times0.949\times10^{6}\cos61.5

F=3.59\times10^{-16}\ N

We need to calculate the acceleration

Using newton's second law

F= ma

a = \dfrac{F}{m}

Put the value into the formula

a=\dfrac{3.59\times10^{-16}}{9.1\times10^{-31}}

a=3.94\times10^{14}\ m/s^2

Hence, The magnitude of the acceleration of the electron at this point is 3.94\times10^{14}\ m/s^2.
