A ball falling though the air has ?

Physics
1 answer:
Sav [38]3 years ago

It has both potential and kinetic energy.

Since the ball is falling through the air its going to keep going faster and faster since gravity is pulling it downward so its not going to stop unless it hits something or someone catches it.

The polynomial 0.041h - 0.018A - 2.69 can be used to estimate the lung capacity, in liters, of a female with height h centimeter
Elden [556K]

Answer:

5 liters.

Explanation:

We are being given the expression

V = 0.041h - 0.018A - 2.69

The height h is 165 cm.

The Age A is 65 years old.

So we replace the values of h and A in the equation given:

V = 0.041 * 165 + 0.018 * 65 - 2.69 = 5.245 liters.

Rounding, we notice that 5.245 liters is closer to 5 than 6. So the answer would be 5 liters.

The box is pushed to the right with a force of 40 Newtons and it just begins to move what is the maximum static frictional force
Vesnalui [34]

Answer:

The maximum static frictional force is 40N.

Explanation:

When an object of mass M is on a surface with a coefficient of static friction μ, there is a minimum force that you need to apply to the object in order to "break" the coefficient of static friction and be able to move the object (Called the threshold of motion, once the object is moving we have a coefficient of kinetic friction, which is smaller than the one for static friction).

This coefficient defines the maximum static friction force that we can have.

So if we apply a small force and we start to increase it, the static frictional force will be equal to our force until it reaches its maximum, and then we can move the object and now we will have frictional force.

In this case, we know that we apply a force of 40N and the object just starts to move.

Then we can assume that we are just at the point of transition between static frictional force and kinetic frictional force (the threshold of motion), thus, 40 N is the maximum of the static frictional force.

Low-pressure areas tend to ____ before occluding and ____ after occluding
alexgriva [62]

Out of the following given choices;

a. decelerate; accelerate

b. accelerate; decelerate

c. stop; accelerate

d. decelerate; stop

<span>The answer is B.  This is because the cold front usually rotates around the warm front as cold air mass coverage in the low-pressure system. This causes the cold air mass to accelerate to catch up with the warm front. When an occluded front ( that is the boundary that separates the older cool air mass already in place from new incoming cold air mass), that the system decelerates. </span>
