During a free fall Swati was accelerating at -9.8m/s2. After 120 seconds how far did she travel? Use the formula =1/2 * t2 to so

lve your answer. (Do not forget to keep units in your answer.)

I think the formula should be x=1/2at^2. This means the answer would be 70560m

newtons 3rd law of motion states that "every action has an equal and oppisite reaction" A golf ball was hit with a force of 200

jolli1 [7]

This relates to newtons law of motion because that golf ball hit so hard that it went the same speed. because its force the more u like hit it your gonna get that force.
hope this makes sense

Four identical particles of mass 0.514 kg each are placed at the vertices of a 4.70 m x 4.70 m square and held there by four mas

Alona [7]

In order to solve the problem it is necessary to take into account the concepts related to the moment of inertia, and the center of mass of the object.

Our values are given by:

m = 0.514kg

I = 4.7m (each side)

A) For the case when the axis passes through the midpoints of opposite sidesand lies in the plane of the square. The formula is given by,

$I = 4m (\frac{l}{2})^2\\I = 4*(0.514)(\frac{4.7}{2})^2\\I = 11.35kgm^2\\$

B) For the case when the axis passes through the midpoint of one of the sides and is perpendicular to the plane of the square. The formula is given by,

$I = 2m(\frac{l}{2})^2+2m(\frac{l}{2}^2+l^2)\\I = 2*(0.514)*(\frac{4.7}{2})^2+2*(0.514)*((\frac{4.7}{2})^2+4.7^2)\\I = 34.06Kgm^2$

C) For the case when the axis lies in the plane of square f passes through two diagonally opposite particles,

$I = \frac{1}{2}*l^2$

$I = \frac{1}{2}*(4.7)^2$

$I = 11.045kgm^2$

Which is not a property of a mineral?<br>O magnetism<br>o cleavage<br>O color<br>o reflection

yKpoI14uk [10]

Reflection. I used the process of elimination. Cleavage and color are properties of a mineral and magnetism is a property as well you just can’t find strong traces of it in all minerals. But it’s there no matter how weak or strong it’s attraction is drawn to magnetic fields.

A car is traveling in a circular curve on a horizontal road at constant speed. Name the force that is responsible for causing it

boyakko [2]

The correct answer is
<span>c the friction force from the road

In fact, the friction force between the road and the tires of the car acts as centripetal force, keeping the car in circular motion.</span>
