Answer:
Capacitive Reactance is 4 times of resistance
Solution:
As per the question:
R = 
where
R = resistance

f = fixed frequency
Now, 
For a parallel plate capacitor, capacitance, C:

where
x = separation between the parallel plates
Thus
C ∝ 
Now, if the distance reduces to one-third:
Capacitance becomes 3 times of the initial capacitace, i.e., x' = 3x, then C' = 3C and hence Current, I becomes 3I.
Also, 

Also,
Z ∝ I
Therefore,




Solving the above eqn:

 
 
        
             
        
        
        
Answer:
42244138.951 m
Explanation:
G = Gravitational constant = 6.667 × 10⁻¹¹ m³/kgs²
r = Radius of orbit from center of earth
M = Mass of Earth = 5.98 × 10²⁴ kg
m = Mass of Satellite
The satellite revolves around the Earth at a constant speed
Speed = Distance / Time
The distance is the perimeter of the orbit

The Centripetal force of the satellite is balanced by the universal gravitational force

The radius as measured from the center of the Earth) of the orbit of a geosynchronous satellite that circles the earth is 42244138.951 m

Answer:
d. 2 hours
Explanation:
because if it travels 100 miles per hour in 1 hour it would travel 200 miles in 2 hours and so fourth.
 
        
             
        
        
        
<u>Answer:</u>
   Ball will move 92.8125 meter along the cliff in 7.5 seconds.
<u>Explanation:</u>
 We have equation of motion ,  , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this case initial velocity = 0 m/s, acceleration = 3.3  , we need to calculate displacement when time = 7.5 seconds.
, we need to calculate displacement when time = 7.5 seconds.
Substituting
   
   So ball will move 92.8125 meter along the cliff in 7.5 seconds.
