A jogger runs at an average speed of 5 ms for 3 minutes then finishes with an average speed of 4 ms for 2 minutes What is his average speed in ms for the run

4.6ms

All objects change velocity as they move toward earth at a rate of 9.8 ms2 due to which factor of gravity

acceleration

Force can be calculated as pressure x area Which of the following will produce the most force

10 p over 10 m2

What does the law of conservation of energy explain

The total energy in the universe is constant.

A+ :)

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

speed of fluide flo

Which fundamental force contributes to pressure in both water and the atmosphere

gravity

When the potential energy of gasoline is converted to the kinetic energy of a moving car what has occurred

Energy transformation has occurred.

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.

For which of these would the buoyant force of air be greatest a bird hotair ballon an airplane

it would be the same for all

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 :)

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

In Pressure can be calculated as forcearea. How much force is exerted by 1000 P over an area of 10 m and sup2 (Hint 1 pascal 1 N exerted over 1 m and sup2)

100 N
