Brittney can run 100 meters in 12 seconds at a constant speed What is her speed in meters per second

8.3 m/s

Resultant velocity is calculated using which two math functions

"addition and subtraction"
Resultant velocity refers to the sum of all vectors in an equation. The two math functions that are used to calculate the resultant velocity are addition and subtraction.

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 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 of the following objects will float on a fluid that has a density of 2 grams cm³

a 5 gram object that is 5 cm³ :)

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.
