Option 4 ( R2 and R3 ) is the correct answer.

Explanation:

In the below given diagram, we can see a circuit diagram that has four resistors such as R1, R2, R3, and R4.
The opening of the circuit is noted as "a" and the ending is noted as "b".
By observing the above diagram, we can clearly see that R2 and R3 are the pair of resistors that are connected in a parallel manner.
Where all the other resistors such as R1 and R4 are neither connected in parallel nor in series.

Hence we can conclude that Resistor R2 and R3 are the ones that are connected in parallel.

M1 = 750Kg, v1 = 10m/s
m2 = 2500Kg , v2= 0 (because in problem say cuz that object don t move).

The momentum before colision is equal with the momentum after colision:

m1v1 + m2v2 = (m1+m2)v3 => v3 is the velocity after colison and that s u want to caluclate for your problem

=> m1v1 = (m1+m2)v3 => v3 = m1v1/(m1+m2) now u should do the math i think v3 prox 2,4 but not sure u should caculate

A long, straight metal rod has a radius of 5.75 cm and a charge per unit length of 33.3 nC/m. Find the electric field at the fol

PIT_PIT [208]

Answer:

Explanation:

From the question;

We will make assumptions of certain values since they are not given but the process to achieve the end result will be the same thing.

We are to calculate the following task, i.e. to determine the electric field at the distances:

a) at 4.75 cm

b) at 20.5 cm

c) at 125.0 cm
