The charge on each coin is equal to
Given the following data:
Force = 2.0 Newton
Radius = 1.5 meters
To determine the charge on each coin, we would apply the law of electrostatic forces:
Mathematically, the law of electrostatic forces is given by the formula:
Note: (since the coin carry identical electric charges).
Therefore, the formula becomes:
Making q the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Answer:
The kinetic theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. When an object is heated the motion of the particles increases as the particles become more energetic
Answer:
4.38 × 10⁻³ A
0.395mΩ
452 µΩ
Explanation:
(a)the current in each strand is = the total current/ number of strand
0.876/ 200 = 4.38 × 10⁻³ A
(b) potential difference = IR
the total resistance = 2.26 µΩ × 0.876
= 0.395mΩ
c) resistance of the cable = 2.26 µΩ × 200
=452 µΩ
Answer:
Product,
P = 639619.091888
Explanation:
In this case, we need to find the product of two numbers. These are as follows :
On doing calculation, we get the product of two numbers as :
P = 639619.091888
In scientific notation the product of two number is given by :
Hence, this is the required solution.
Answer:
Given:
Initial velocity (u) of the object = 0 m/s (Body starts from rest)
Height above the ground (h) = 36 m
Accelration due to gravity (g) = 10 m/s²
To Find:
Time taken (t) by the object to hit the ground
Explanation:
From equation of motion for object under gravity we have:
Substituting values of h, u & g in the equation we get:
