Answer:
The potential difference across a given given wire of an circuit is directly proportional to the current flowing through it provided it's temperature remains the same. This is known as ohm's law
V is proportional to I
V/I = constant
V/I = R
V = IR where R is the constant of proportionality and resistance of the wire
Hope this helps!
Answer:
(a) Magnetic force 
(b) Acceleration 
(C) Speed will remain same
Explanation:
We have given velocity of alpha particle v = 520 m/sec
Magnetic field B = 0.034 T
Charge on alpha particle 
Mass of alpha particle 
Angle between velocity and magnetic field 43°
(a) Force acting on the particle is equal to



(B) According to newton's law
F = ma. here m is mass and a is acceleration.
So acceleration

(c) As the magnetic force is always perpendicular to velocity so speed will remain same neither decreases nor increases.

Hey I up for a good time with the wrestling tournament and I have a tournament couple of minutes early and we are
Answer:
a) the number of particles increases
b) average distance between them should decrease
c) the number of particles decreases, the pressure must also decrease
Explanation:
a) When the girl pumps to increase the pressure inside the tire she introduces more particles. Therefore the number of particles increases
b) as the volume of the tire does not change and there are more particles, the average distance between them should decrease
c) When a hole is opened, some of the particles inside the tire come out, so as the number of particles decreases, the pressure must also decrease
