An airplane flies horizontally at constant speed in a straight­line direction. Its state of motion is unchanging. In other words
Alex_Xolod [135]

Answer:

sum of all forces on the air plane must be ZERO

So both forces must be of same magnitude

Explanation:

As we know that airplane is moving with uniform speed is horizontal plane is a straight line

so the motion of the air plane is uniform without any acceleration

So we will have

a = 0

acceleration must be zero

now by Newton's law

F_{net} = 0

F_1 + F_2 = 0

so sum of all forces on the air plane must be ZERO

An electron moving at right angles to a 0.1 T magnetic field experiences an acceleration of 6 × 1015 m.s-2. What is the speed of
GaryK [48]

Explanation:

It is given that,

Magnetic field, B = 0.1 T

Acceleration, a=6\times 10^{15}\ m/s^2

Charge on electron, q=1.6\times 10^{-19}\ C    

Mass of electron, m=9.1\times 10^{-31}\ kg    

(a) The force acting on the electron when it is accelerated is, F = ma

The force acting on the electron when it is in magnetic field, F=qvB\ sin\theta

Here, \theta=90

So, ma=qvB

Where

v is the velocity of the electron

B is the magnetic field

v=\dfrac{ma}{qB}

v=\dfrac{9.1\times 10^{-31}\ kg\times 6\times 10^{15}\ m/s^2}{1.6\times 10^{-19}\ C\times 0.1\ T}

v = 341250  m/s

or

v=3.41\times 10^5\ m/s

So, the speed of the electron is 3.41\times 10^5\ m/s

(b) In 1 ns, the speed of the electron remains the same as the force is perpendicular to the cross product of velocity and the magnetic field.

Question 5
Alekssandra [29.7K]

Answer:

Question 5: The outer core has a lower temperature and lower pressure than the inner core

This is because the outer core is not as hot as the inner core. It is also under slightly less pressure. Due to this, the outer core is liquid and less dense than the inner core.

Question 6: I'm not sure what the answer to that is.. but I believe you'll figure it out!
