A3.5 kg object has a momentum of 26 kg-m/s. calculate the speed of the object.

7.43 m/s

Explanation:

p = mv

26 kg m/s = (3.5 kg) v

v = 7.43 m/s

7.4 m/s

Explanation: Momentum is expressed in p = mv

We derive the equation to have  v = p / m

Substitute the values:

v= 26 kg m/s / 3.5 kg

  = 7.4 m/s

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

the higher the current the higher the mag field around it the higher the influence on the compass
