I suppose the answer would be C. Kepler's three laws talk about planetary orbit.

Number c is right answer because it doesn't talk about forces rather it talks about planetary motions and orbits

What electric force would a stationary 3.8 C charge experience if it were far away from any other charges

MAVERICK [17]

Answer:

The electric force will be 0 N

Explanation:

From the question we are told that

The magnitude of the charge is $q_1 = 3.8 \ C$

Generally from Coulombs law the electric force between two charges is mathematically represented as

$F = \frac{ k * q_1 q_2 }{r^2}$

Here r is the distance of separation between that two charges.

Now from the question we are told that the charge is far away from any other charge hence we can say that the distance between the charge and any other charge is $r = \infty$

$F = \frac{ k * 3.8 * q_2 }{\infty^2}$

=> $F =0 \ N$

Hence the electric force will be 0 N

A car travels at a constant speed up a ramp making an angle of 28 degrees with the horizontal component of velocity is 40 kmh^-1

Hoochie [10]

Answer:

Vx = 35.31 [km/h]

Vy = 18.77 [km/h]

Explanation:

In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.

$v_{x} = 40*cos(28)\\V_{x} = 35.31 [km/h]$

In order to find the vertical component, we must use the sine function of the angle.

$V_{y}=40*sin(28)\\V_{y} = 18.77 [km/h]$

I need the answer to this question what has the student plotted on the vertical axis?

expeople1 [14]

Answer:

The correct option is D

Explanation:

In trying to achieve what the student wanted to see, which is to see the relationship between the weight the cord can hold and how long the cord will stretch. Since the origin of the graph is from zero, the value plotted on the vertical axis would be just the length caused by each weights. Thus, <u>the original length would have to be subtracted from the measured length to determine the actual length caused by the weight added to the cord</u>.
