<span>You can start with the equations you know 
a=v^2/r = (2pi*r/T)^2/r = 4pi^2r/T^2 
Radius of earth (R) = 6378.1 km 
Time in one day (T) = 86400 seconds 
Latitude = 44.4 degrees 
If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r. 
r=Rcos(44.4) 
r=6378.1cos(44.4) 
r= 4556.978198 km or 4556978 m 
Now you can plug this value into the acceleration equation from above... 
a= 1.8*10^8/7.47*10^9 
a= .0241 m/s^2 </span>
        
             
        
        
        
It means you can do 550 Newton Meters of work every second. Power is the rate of doing work, I hope this helps
        
             
        
        
        
<h2><u>Question</u><u>:</u><u>-</u></h2>
Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the work done by Ryan?
<h2><u>Answer:</u><u>-</u></h2>
<h3>Given,</h3>
=> Force applied by Ryan = 10N
=> Distance covered by the book after applying force = 30 cm 
<h3>And,</h3>
30 cm = 0.3 m (distance)
<h3>So,</h3>
=> Work done = Force × Distance
=> 10 × 0.3
=> 3 Joules

 
        
        
        
Answer: 0.42 Amperes
Explanation:
Given that:
Current, I = ?
Electric charge Q = 100 coulomb 
Time, T = 4.0 minutes
(The SI unit of time is seconds. so, convert 4.0 minutes to seconds)
If 1 minute = 60 seconds 
4.0 minutes = 4.0 x 60 = 240 seconds 
Since electric charge, Q = current x time
i.e Q = I x T
100 coulomb = I x 240 seconds 
I = 100 coulomb / 240 seconds 
I = 0.4167 Amperes (round to the nearest hundredth which is 0.42 amperes)
Thus, 0.42 Amperes of current flows in the circuit.
 
        
             
        
        
        
Explanation:
The kinetic energy is said to be possessed due to the motion of the object. An object at rest will have zero kinetic energy and if it is in motion it will have some kinetic energy. The mathematical expression for kinetic energy is given by :
 ...........(1)
...........(1)
Where
m is the mass of the object
v is the velocity of object
It is clear form expression (1) that the kinetic energy of the object is directly proportional to the mass and velocity of an object.
So, the hypothesis for the mass and kinetic energy can be written as " when the mass of the object increases, its kinetic energy also increases because there exists a direct relationship between the mass and the kinetic energy of the object".
