When a 1.50V battery is shorted by a copper wire whose resistance can be ignored, the current through the copper wire is 2.75 A.
viva [34]

Answer:

Internal resistance = 0.545 ohm

Explanation:

As per ohm's law we know that

V = iR

here we know that

i = electric current = 2.75 A

V = potential difference = 1.50 Volts

now from above equation we have

1.50 = 2.75 ( R)

now we have

R = \frac{1.50}{2.75}

R = 0.545 ohm

A car accelerates at a rate of 8.8 m/s² with a force from the tires of 15,840 N.
dezoksy [38]

Answer:

1,800kg

Explanation:

Force = Mass x Acceleration

F = m x a

15840N = m x 8.8

8.8 x m = 15840

m = 15840/8.8

= 1,800kg
