When a potential difference of 20 V is applied to a given wire, it conducts 0.25 A of current.?

1 answer:

4 0

Well if the wire has an insane length or is made out of a high resistance material. But, you're probably looking for a resistor : R = U / I ; R = 20V / 0.25A

a runner covers the last straigjt stretch of a race in 4 s. during that time, he speeds up from 5m/s to 9m/s.

During that final period of time,
his acceleration is
(9 m/s - 5 m/s) / (4 sec) = 1 m/s² .

A 10.00-kilogram block slides along a horizontal, frictionless surface at 12.0 meters per second for 6.00 seconds. The magnitude

earnstyle [38]

Answer:

120 kg m/s

Explanation:

The magnitude of the momentum of an object is given by

$p=mv$

where

m is the mass of the object

v is its speed

For the block in this problem,

m = 10.0 kg (mass of the block)

v = 12.0 m/s (speed of the block)

Therefore the magnitude of the block's momentum is

$p=(10.0 kg)(12.0 m/s)=120 kg m/s$
