Answer:
2.35 x 10^{5} J
Explanation:
force (f) = 1080 N
distance (d) = 218 m
find the work done
work is said to be done when force applied to an object moves the object, therefore work done = force x distance
work done = 1080 x 218 = 235,440 J = 2.35 x 10^{5} J
Answer:
E=Ur/2E_{0}
Explanation:
Consider a long cylindrical charge distribution of radius R with a uniform charge density rho. (a) Find the electric field at distance r from the axis where r R.
to find the electric point inside the cylinder
r=radius of the cylinder
A=curved surface area of the cylinder
∪=charge density
Q=is the net charge
V=volume of the cylinder
Q=UV
volume of the gaussian cylinder =
Q=U
area A=
Write the expression Gaussian law
∅=∫EdA=Q/..........................1
E_{0} is the permittivity of free space and Eois the electric field
rewriting the equation 1 , we have
EA=Q/E_{0}
substituting for A and also for Volume V in the equation above
E*=U/E_{0}
E=Ur/2E_{0}
Explanation:
Boyles law is the pressure of a fixed mass of gas which is inversely proportional to its volume provided that the temperature is kept constant.
The average power produced by the rocket is the product of force exerted by the rocket and the velocity of the rocket.
<h3>Average power produced by the rocket</h3>
The average power produced by the rocket is calculated as follows;
P = FV
where;
- P is the average power
- F is the force exerted by the rocket
- V is the velocity of the rocket
Thus, the average power produced by the rocket is the product of force exerted by the rocket and the velocity of the rocket.
