which of the following objects is considered negatively charged A - one with excess electrons on the surface B - one with excess
Ne4ueva [31]
An object that could be considered as negatively charged would be when it has an excess of an electron in its atom. However, when it loses an electron, it could go back to its stable state which is "uncharged" or when there is an excess proton, it could be a positively charged object.

Runner A is initially 6.0 km west of a flagpole and is running with a constant velocity of 9.0 km/h due east. Runner B is initia
sergejj [24]

Answer:

0.176m from the flagpole, westward.

Explanation:

Let the Eastward be the positive direction. So initially runner A is at position -6km, running with velocity of 9km/h while runner B is at position 5km running at a velocity of -8km/h. We can conduct the following equation for their distances over the same time t

s_A = -6 + 9t

s_B = 5 - 8t

When A an B meets, they are at the same position and at the same time. So

s_A = s_B

-6 +9t = 5 - 8t

17t = 5 + 6 = 11

t = 11/17 = 0.647 s

s_A = -6 + 9*0.647 = -0.176 m

So where they meet is 0.176m from the flagpole, westward.

A light-year is the distance that light can travel in one year. If the sun is 1.5 x 10⁸ km away, how many light years is the sun
photoshop1234 [79]

Answer:

0.00001581 light years

Explanation:

distance divided by speed of light= 150,000,000/300,000= 500 seconds 8.3333

8.3 minutes

now divide this by 60 x 24 x 365.25. so you will get answer=  

.000015823 light years.

What direction does centripetal acceleration point?
Nesterboy [21]

Answer:

Inward

Explanation:

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced. hope this helps :)
