you throw an object straight up at 15m/s. how fast is it going when it gets back to the height from which you threw it?

1 answer:

8 0

At the same speed because it will slow down as it approaches the peak then speed up as it goes down again

it will be going 15m/s when it gets to the same height if we neglect air resistance and the object doesn't hit something

Consider two solid spheres of radius R with uniformly distributed charge throughout their volumes. Point

8090 [49]

The ratio of the total charge on the charges, Q2/Q1 is; 9

<h3>Electric field and Total Charge</h3>

The electric field due to a charge is directly proportional to its magnitude and inversely proportional to the square of the distance to such point;

Since, E1 = E2, it follows that;

Q1/(d1)² = Q2/(d2)²

Where, d1 = 0.5 and d2 = 1.5

Q1/(0.5)² = Q2/(1.5)²

Q1/0.25 = Q2/2.25

Hence, Q2/Q1 = 2.25/0.25

Q2/Q1 = 9.

Describe the forces acting on an object that is moving at a constant velocity.

Serhud [2]

Answer:

0 Newton

Explanation:

If the velocity becomes constant the acceleration will be zero and the net force will be zero because:

force = mass x acceleration

Since acceleration is 0:

force = mass x 0

force = 0
