You are making an electric circuit with a battery providing 3.0 V, and two resistors of resistance of 2.0 Ohm and 8.0 Ohm connected in parallel to the battery. What is the current out of the battery in A?
part2: knowing the potential difference across both resistors is 3.0 V, calculate the current going through the
2.0-Ohm resistor in A.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
