Answer:
The answer to your question is: C. -9.81 m/s²
Explanation:
A. 9.81 m/s² acceleration is considered positive when it goes to the center of the earth, so this option is incorrect.
B. 0 m/s² This option is incorrect because acceleration is 0 for a linear motion without acceleration.
C. -9.81 m/s² If a projectile goes to the sky, then the acceleration will be negative.
D. It is not constant. Acceleration is constant.
Answer:
Yes.
Explanation:
A negative power would just represent a loss of power. So in your case it lost -1252.16 W
Answer:
The time rate of change of flux is 
Explanation:
Given :
Current 
A
Area of plate 
Plate separation 
m
(A)
First find the capacitance of capacitor,
Where 
F
But 
Where 
Now differentiate above equation wrt. time,
Therefore, the time rate of change of flux is
The heat is transferred to one material to another, however insulators minimize that transfer, keeping it in the area, warming it.
