Answer:
Net Force = mass x acceleration
Explanation:
Using Newton's second law we can easily see that Net force is the scalar product of mass and acceleration.
Answer:
The average power is
Explanation:
From the question we are told that
The energy of the appliance is
The time considered is
Generally the average power consumption is mathematically represented as
=>
=>
Answer:
Potential energy is converted into kinetic energy by a force. For example, when you pick up a rock, you work against gravity to give it some potential energy. And then when you drop it, the gravitational force causes the rock to accelerate towards the ground
Explanation:
Answer:
B. 3.75 meters/second2
Explanation:
The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car;
acceleration = (change in velocity)/(change in time)
acceleration = ( 30 - 0)/(8)
acceleration = 3.75 meters/second2
