Answer:
Explanation:
The beam of positively charged particles would not be deflected if the electric force acting on them is equal to the magnetic force:
where
q is the charge of the particles
E is the magnitude of the electric field
v is the speed of the particles
B is the intensity of the magnetic field
is the angle between the direction of v and B
Since the beam of particles travels perpendicular to the magnetic field, we have 
. So, we can rewrite the equation as
where
Substituting into the formula,
I think that it would help him so it can slide and help him move his furniture faster
Answer:
A gas is not used in hydraulic machines as the fluid because gas is easily compressible and so if a gas is used, the energy would mostly go into compressing a gas. Therefore a liquid is used in hydraulic machines as the fluid.
Explanation:
I got you bro:)
It is the force applied to a machine
in order to accomplish work.
Explanation:
Let us assume that the separation of plate be equal to d and the area of plates is 
. As the capacitance of capacitor is given as follows.
C = 
It is known that the dielectric strength of air is as follows.
E = 
Expression for maximum potential difference is that the capacitor can with stand is as follows.
dV = E × d
And, maximum charge that can be placed on the capacitor is as follows.
Q = CV
= 
= 
= 
= 
or, = 10.62 nC
Thus, we can conclude that charge on capacitor is 10.62 nC.
