Objects can be charged by the transfer of electrons.<br> True<br> False

Sveta_85 [38]

Answer:

True

Explanation:

Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.

I tried, hope this helps :)

A crane lifts a car with 9023 J of kinetic energy. The crane lifts the car with a speed

lapo4ka [179]

Answer:

m = 2301.8 [kg]

Explanation:

This problem can be solved in an easy way using the definition of kinetic energy, in this way you can clear the mass, depending on the known variables.

$E_{k}=0.5*m*v^2\\replacing\\\\9023 = 0.5 *m*(2.8)^2\\m = 2301.8[kg]$
