Answer:

they can do work easier for an example a car a car make things easier by going some were far it can also be used to help people travel instead of a plane it can also be used for carriying things like a boat. (you can put it in a diffrent way)

Explanation:

hope it helps! :)

Answer:

Machines reduce the time of work hence reducing the rate of doing work ( power ).

Machines e.g pulleys carry heavy loads with a less and reasonable effort.

Machines e.g generators induce current in a limited amount of time

I NEED THIS A SOON AS POSSIBLE

Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.

ball A of mass 5.0 kg moving at 20 meters per second collides with ball B of unknown mass moving at 10. meters per second in the

antiseptic1488 [7]

Answer:The mass of ball B is 10 kg.

Explanation;

Mass of ball A = $M_A=5 kg$

Velocity of the ball A before collision: $U_A=20 m/s$

Velocity of ball A after collision= $V_A=10 m/s$

Mass of ball B= $M_B$

Velocity of the ball B before collision: $U_B=10 m/s$

Velocity of ball B after collision= $V_B=15 m/s$

$M_AV_A+M_BV_B=M_AU_A+M_BU_B$

$5 kg\times 10 m/s+M_B\times 15=5 kg\times 20m/s+M_B\times 10m/s$

$M_B=10kg$

The mass of ball B is 10 kg.

Differentiate scalar & vector quantity?

Keith_Richards [23]

$\textbf{Hello Friend}$

Scalar Quantity :-

→ These are the quantities with magnitude only . These quantities doesn't have to be mentioned with direction

eg.)=> Mass , Temprature .

Vector Quantity :-

→ These quantities are described with both Magnitude and Direction . These quantities follow special type of algebra called Vector algebra .

eg.)=> Force , Displacement
