Answer:

7.401 * 10^(-15) N

Explanation:

30 electrons will have a charge:

30 * -1.6022 * 10^(-19) C

= - 4.806 * 10^(-18) C

The relationship between electric field and electric force is:

E = F/q

This means that force, F, is

|F| = |E|*|q|

|F| = |1540| * |-4.806 * 10^(-18)|

|F| = |-7401.24 * 10^(-18)|

|F| = 7.401 * 10^(-15) N

Consider the following system, where F = 80 N, m = 1 kg, and M = 11 kg M m F What is the magnitude of the force with which one b
Lorico [155]

Answer:

Force exerted by the lighter block on the heavier block is 6.63 N

Explanation:

Given Data

F = 80N

m = 1kg

M = 11kg

Solution:

*We assume that there is no friction

Calculating the acceleration of the system

a = \frac{F}{m+M}

a = \frac{80}{1+11}

a = \frac{80}{12}

a = 6.67ms^{-2}

Let's write the Equation of Motion of the heavier block  

F_{1} = F - F_{2}

Ma = F - F_{2}

force exerted by the lighter block on the heavier block is calculated as

 F_{2} = F - Ma

 F_{2} = 80 - (11 x 6.67)  

 F_{2} = 6.63 N

An airplane flies 12 m/s due north with a velocity of 35.11 m/s. how far east does it fly?
goblinko [34]
The plane's velocity of 35.11 m/s is actually due in a north-eastward direction. The 12 m/s velocity is the vertical component of the plane's velocity, hence it is pointing northwards. We will use the formula:

Vy = Vsin∅

To determine the angle ∅ at which the plane is flying. This is:

12 = 35.11 * sin∅
∅ = 20.0 degrees

The eastward velocity is:

Vx = Vcos∅
Vx = 35.11 * cos(20)
Vx = 33.0 m/s

The plane's eastward velocity is 33.0 m/s
