What’s the resistance in the circuit
inna [77]

Answer:

I = 0.75 A

Explanation:

The question is not to calculate the resistance, but to calculate the current. (The resistance is already given by the value of 2 Ohm).

U = I * R

I = U / R

with U = 1.5 V and R = 2 Ohm

I = 1.5 / 2

I = 0.75 A

I am Lyosha [343]
Thank you for posting your question here at brainly. I think your question is incomplete. Below is the complete question, it can be found elsewhere:

What is the probability of finding an electron within one Bohr radius of the nucleus?<span>Consider an electron within the 1s orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by 1-a0^2[a0^2-e^(-2R/a0)(a0^2+2a0R+2R2)]. Where a0 is the Bohr radius (for a hydrogen atom, a0 = 0.529 Å.). What is the probability of finding an electron within one Bohr radius of the nucleus? What is the probability of finding an electron of the hydrogen atom within a 2.30a0 radius of the hydrogen nucleus?

Below is the answer:

A car has an acceleration of 1.5 m/s2. A net force of 2100 N is acting on the car. What is the mass of the car?
gulaghasi [49]

Answer:

Given

acceleration (a) =1.5ms2

Force(F) =2100N

R. t. c mass (m) =?

Form

F=ma(divided by m both sides)

m=F/a

m=2100/105

m=1400kg

mass of car =1400kg
