It is gravity. As a sky diver falls (ignoring air resistance for now) he increases in acceleration due to gravity, or 9.81m/s^2 (Earth's gravitational acceleration). Inertia is, by definition, <span>a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force (credit to Google). However, if the sky diver has some kind of webbing on his suit, a drag force opposite to gravitational weight cancels it, and it moves at a constant drag velocity.

Sorry I got carried away... physicist...

It is gravity. Hope this helps!</span>

Explanation :

When an object moves under the action of gravity. Then the object is said to be moving under free fall.

We know that the acceleration due to gravity is denoted by g and it is equal to 9.8\ m/s^2.

If the body is accelerating towards the gravity the value of g is positive while when it is accelerating against the gravity it is negative.

As the skydiver falls to Earth, she experiences positive acceleration due to gravity.

So, the correct option is (a) gravity.

Two forces act on an object. One force has a magnitude of 10 N directed north, and the other force has a magnitude of 2 N direct
xeze [42]

Answer:

8 N North.

Explanation:

Given that,

One force has a magnitude of 10 N directed north, and the other force has a magnitude of 2 N directed south.

We need to find the magnitude of net force acting on the object.

Let North is positive and South is negative.

Net force,

F = 10 N +(-2 N)

= 8 N

So, the magnitude of net force on the object is 8 N and it is in North direction (as it is positive). Hence, the correct option is (d) "8N north".

What distance should be used to pattern a shotgun hunter ed?
Murljashka [212]
I think the distance that should be used is the distance that one expects to be from the game you are hunting. Before taking a shotgun for a gobbler or even for ducks or other animals, you need to see how your gun performs by patterning it at various ranges with the load you want to use.

A car maintains a constant speed v as it traverses the hill and valley as shown below. Both the hill and valley have a radius of
Zigmanuir [339]

Answer:

As given that the car maintains a constant speed v as it traverses the hill and valley where both the valley and hill have a radius of curvature R.

(i) At point C, the normal force acting on the car is largest because the centripetal force is up. gravity is down and normal force is up. net force is up so magnitude of normal force must be greater than the car's weight.

(ii) At point A, the normal force acting on the car is smallest because the centripetal force is down. gravity is down and normal force is up. net force is up so magnitude of normal force must be less than car's weight.

(iii) At point C, the driver will feel heaviest because the driver's apparent weight is the normal force on her body.

(iv) At point A, the driver will feel the lightest.

(v)The car can go that much fast without losing contact with the road at A can be determined as follow:

Fn=0 - lose contact with road

Fg= mv²/r

mg=mv²/r

v=sqrt (gr)

A bullet leaves a gun with a horizontal velocity of 100 m/s. Calculate the distance it would travel in 1.3 seconds.
salantis [7]

Answer:

130m

Explanation:

You just have to multiply velocity by the time traveled:

100m/s * 1.3s = 130m!
