Answer:the velocity is zero, the acceleration is directed downward, and the force of gravity acting on the ball is directed downward.
Explanation:
When a ball is tossed vertically upwards, it reaches its maximum point. This maximum point is known as the maximum height of the ball. At this maximum height, its velocity is zero, its acceleration is directed downwards and the force of gravity acting in the ball is directed downwards towards the earth.
Answer:
At a distance of 1376.49 candle emits 0.2 watt power
Explanation:
Distance between Sun and earth 
Sun emits a power of 
Power emitted by candle = 0.20 watt
We know that brightness is given by
So 
So at a distance of 1376.49 candle emits 0.2 watt power
To see what causes a change in experiment. If they kept everything the same what would be the point of experiment? One thing has to be different to test and get a result ! They have to see how that one variable changes the experiment. If they change so many things then the experiment will be messed up. They have to focus on that one variable during experiment to get the proper result. Hope this helps you. Think about it if you want to know how antibiotic effects bodies. You choose two people and you give antibiotic to one. And you don't give any other drug to the people you are testing. Because you truly want to know the effect of antibiotic alone.
