What if your body applies force to the ground as weight If you weigh 450 newtons and carry a backpack that weighs 45 newtons what is the net force applied downward to the ground

495 n

What term describes the transfer of energy between objects that have different average kinetic energies

The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.

What instrument can be used to calculate specific heat capacity

A calorimeter can be used to calculate specific heat capacity.

What does the law of conservation of energy explain

The total energy in the universe is constant.

A+ :)

Which factors must be known to calculate an object's gravitational potential energy

height and mass

What is the factor described by Bernoulli's principle that allows airplanes to fly

speed of fluide flo

Which SI unit for energy is also called the newton-meter

The newton metre is a unit of torque (or moment).

What is the method used to produce nuclear energy in power plants

nuclear fission

What is the term used to describe the rate of an object's movement

The term used to describe the rate of an object's movement is speed or velocity. Velocity is the same as speed but also measures direction.

Which term defines something that transfers thermal energy efficiently

Something that transfers thermal energy efficiently is called a conductor.

What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²

In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second.

The magnitude of velocity increases by that amount, while the direction of velocity

doesn't change.

Which of these statements is true about the middle coloines

They had a large variety of farm products
