Answer:
The ratio (U₁/U₂) = 6
Explanation:
U, the potential energy is given as
U = kqQ/r
k = Coulomb's constant
q = charge we're concerned about
Q = charge of the negative plate of the capacitor
r = distance of q from the negative plate of the capacitor.
For charge q₁
U₁ = kq₁Q/s
U₂ = kq₂Q/2s
But q₂ = q₁/3
U₂ becomes U₂ = kq₁Q/6s
U₁ = kq₁Q/s
U₂ = kq₁Q/6s
(U₁/U₂) = 6
Answer:
gathered by using measurement tools and math
Explanation:
Quantitative data is often gathered by using measurement tools and math.
A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.
- Each data set has a unique numerical value and can be counted.
- Qualitative data set does not use numerals and numbers.
- It engages the senses to make some scientific deductions.
- Examples are measurement of volume, distance, length, time, number of moles e.t.c
- Qualitative data sets include taste, smell, color e.t.c
Answer:
(a) Magnitude of force is 262.51 N
(b) Angle with East direction is 
Explanation:
Force by Jack in vector form
Force by Jill in Vector form is given by

Force by Jane is

Net force is:

Hence

The net force will be given by

Since
and 

The direction of net force is:

Since
and

The angle with East direction is 
Net force exerted on the donkey is in the south-east direction. So, the angle of net force from the east direction is
and it is
from the south.
Answer:

Explanation:
From the question we are told that
The number of turns is 
The radius is 
The position from the center consider is x = 3.45 cm = 0.0345 m
The induced emf is 
Generally according to Gauss law

=> 
Where A is the cross-sectional area of the solenoid which is mathematically represented as

=> 
=>
ggl;
Here
is the permeability of free space with value

=> 
=> 
For this question, you must divide 48 million by two hundred thousand to get your answer. The quotient of these number is 240, which if reduced to days, is exactly ten days.
