PLEASE HELP I REALLY NEED IT

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
3 0

Answer:

9. Force is required to change an object velocity.Force is equal to mass times acceleration.

10.  Force acting on object are paired with equal and opposite forces

Step-by-step explanation:

9.

Newton's 2nd law states that force is a product of mass and acceleration.In this case, the force of friction is causing deceleration of the ball.This is an example of rolling friction.Acceleration of the ball depends directly on this friction but indirectly on its mass.

10.

From Newton's 3rd Law ,for every action there is an equal and opposite reaction.The astronaut throwing the ball will experience the effect of an external force againts his own which is equal  and  in the opposite direction to the force she applied.This is why the astronaut moves backward but slower.

By looking at this scatter plot you can see that 2 people bowled above their average, 1 person bowled the same number for their average and their highest score (this person bowled 200 as their highest score as well as their average), and the biggest difference between someones high score and their average is one person has 200 for their bowling average, but only 175 for their high score. Everyone else's high scores and averages are about the same.

musickatia [10]

Answer:

7,897.30 miles

Step-by-step explanation:

It is given that the North Pole is at a distance of 3,949 miles from the center of the earth.

We also know that the sea floor is below 2.4 miles from the sea level.

It is given that a submarine is located at the sea floor near North Pole. Hence, the distance of the submarine from the center of the earth would be

3949 - 2.4 = 3946.6 miles.

On the other hand, the South Pole is given to be at an elevation of 1.7 miles from the sea level.

Since we know that the sea level is at a distance of 3949 miles from the center of the earth, we can immediately calculate the distance of the South Pole from the center of the earth to be

3949 + 1.7 = 3950.7 miles.

Putting all of this together, we see that the center of the earth is at a distance of 3946.6 miles from the submarine near the North Pole, and the center of the earth in turn is 3950.7 miles from the South Pole.

Hence, the distance between the submarine and a person on the South Pole = 3946.6 + 3950.7 = 7897.3 miles.

HELPPP QUICKKK PLSSSS PEOPLE I NEED HELP NOW PLSSSSS Which of the following equations describes the line shown below? Check all
Sav [38]

Let there exists a point (x, y) on the given line.

Slope of all points must be same, as they lie on the same line.

=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)

=> (y - 1)/(x - 2) = - 1/2

=> y - 1 = (-½) (x - 2)

Option 1 is the correct option
