Answer:
E = 401.3 eV
Explanation:
As we know that the thinnest gap in the direction of metal is given as
so here we can say that lowest energy of photon will not able to break this electron from above thickness
so we will have
here we have
also we have
so we will have
Answer:
8.3 x 10⁻⁷ C
Explanation:
Electric flux will enter the face at x=0 and exit at face x= 25 m
On the other faces , field lines are parallel so no flux will enter or exit .
Flux entering the face at x = 0
= electric field x face area
= 560 x 25 x 25 = 350000 weber
Flux exiting the face at x = 25
= 410 x 25 x25
= 256250 weber
Net flux exiting from cube ( closed face )
350000 - 256250 = 93750 web
Apply gauss'es theorem
Q / ε = Flux coming out
Q is charge inside the closed cube
Q / ε = 93750
Q = 8.85 x 10⁻¹² x 93750
= 8.3 x 10⁻⁷ C
Answer:
If you’re going to be shooting a lot, get a surplus flak jacket. This isn’t a bulletproof vest, it just stops fragmentation or shrapnel. More importantly, it absorbs shock. You can fire a 12 gauge shotgun all day long and you won’t feel sore at all.

<span>1. Frictional force</span>
A naturally occurring force related
to two bodies in motion is frictional force. Friction is a type of force which
includes two bodies resisting each other –either motion of solid surfaces,
fluid layers, material elements and compounds gliding against each other. They
key point of this frictional force is that the two forces are in the opposite point
of direction with each other. For example, when you are cold, as you rub your
hands together notice that when your right hand is going upward, your left hand
is downward and thus creates heat. That is one type of friction force outcome,
the heat.
Answer:
is applied to
Explanation:
An input force is push or pull that is applied to the machine and causes work to be done on it.
Input force for every machine should be lesser than the output force. The output force is the resulting force which produces work.
The force produced by any machine is a function of the input force and the design of the machine.
Any force applied to a machine is the input force.
