As you illustrate the problem, you may come up with the same diagram as the one shown in the attached picture. The relative velocity is the linear velocity between the two velocities. This is calculated by simply finding the difference of their velocities. Since, the velocity is with respect to Jane relative to Mary, the solution is as follows:
Relative velocity = Velocity of Jane - Velocity of Mary
Relative Velocity = 4.67 m/s - 3.59 m/s =
1.08 m/s
ANSWER

EXPLANATION.
To write in scientific notation means , we write in form,

Where n is an integer and

The given number is,

We move the decimal point backward to obtain our k, the n here is 9, because we moved backward 9 times.
This implies that,

The correct answer is D
Considering that Work, W, is:
W=F·d
You have: 224=F·32
So that F=7 N
All scientists on Earth are human beings. That's the only thing you can say that applies to ALL of them.
Answer:
option b
Explanation:
There is an object pulled inward in an electric field.
We have to find out of the four options given which is true.
a) The object has a neutral charge is false since when electric field pulls the object inward, there is a charge inside.
b) The object has a charge opposite that of the field, this option is correct since there will be an equal and opposite charge created by the object
c) The object has a negative charge will be correct only if the original charge was positive hence wrong
d) The object has a charge the same as that of the field is incorrect since this would be opposite the charge
So only option b is right
