Answer:
The charge on point A is 
= 2.4 × 
C
The charge on point B is 
= 1.2 × C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.
F = 46 N
We know that force between the charges is given by
= 1.2 × C
= 2 ×
= 2 × 1.2 ×
= 2.4 × C
Therefore the charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
In order to change the frictional force between two solid surfaces, it can be changed by shorter distances and by the amount of weight it has or the amount of force that is pushing that object to go however distance it can.
The net magnetic field between the two parallel wires is determined as 1775 nT.
<h3>Magnetic field at wire 2 due to current 1</h3>
The magnetic field is calculated as follows;
<h3>Magnetic field at wire 1 due to current 2</h3>
The magnetic field is calculated as follows;
<h3>Net magnetic field</h3>
B = BZ1 + BZ2
B = 1.2 x 10⁻⁶ + 5.75 x 10⁻⁷
B = 1.775 x 10⁻⁶ T
B = 1775 x 10⁻⁹ T
B = 1775 T nT

Answer:
900
Explanation:
v = s / t = 9000m / 10 s = 900m/s
Answer: D. Albedo
Explanation:
The proportion of total light incident on surface that is reflected back is called its albedo. These are typical features of an astronomical body. It is a dimension less quantity and its value ranges from 0 to 1. Light surfaces reflect larger amount of light than dark surfaces. This feature can be clearly seen on planet Mars and the Moon.
Thus, the fraction of the total radiation that is reflected by any surface is called its <u>Albedo.</u>
