The movement of the earth is so small, especially compared to you, that you don't realize it. This is because the earth's mass is so much greater than your mass.
Answer:
F' = 162 units
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:

where,
F = gravitational force = 18 units
G = Gravitational Constant
m₁ = mass of object 1
m₂ = mass of object 2
r = distance between objects
Therefore,

Now, if we change the value of distance to one-third of original value, then:
r' = r/3

using eqn (1):
F' = 9(18 units)
<u>F' = 162 units</u>
Answer:
I = 2.33 µA
Explanation:
given,
Effective resistance (R)= 300 Ω
Voltage of signal (V)= 700 µV
current flow in the antenna = ?
Using ohm's law
V = I R
where I is the current flow


I = 2.33 x 10⁻⁶ A
I = 2.33 µA
Hence, the current flow in the antenna downloaded is equal to I = 2.33 µA
Answer:
The charge on the bead is 
Explanation:
From the question we are told that
The mass of the bead is 
The magnitude of the electric field is 
The acceleration of the bead is 
Generally, the electric force on the bead is mathematically represented as

Where q is the charge on the bead
Now the gravitational force opposing the upward movement of the bead is mathematically represented as

Generally the net force on the bead is mathematically represented as

=> 
Now substituting values
