Answer:

2. A baseball

4. A javelin thrown

Explanation:

In projectile motion all the objects will have two components of motion under gravity.

Horizontal component of motion must remains constant as there is no force in that direction while in vertical direction due to gravity the speed must change.

So whenever an object is projected at some angle with the horizontal which is less than 90 degree then in that case the motion must be projectile motion.

So here the correct options are

2. A baseball

4. A javelin thrown

Could someone help me with these few problems

ivolga24 [154]

1. Pressure = Force/Area

When a ballon is pressed against many pins then the area is increased as compared to when it is pressed against a single pin. The force by which the balloon is pressed remains the same. Less the area, more the pressure. So, the balloon pops when it is pressed against one pin.

2. The candle goes off when covered with a glass because for burning the candle need oxygen. When glass on placed on the candle then the oxygen supply is stopped. So, when available oxygen is finished, the candle goes off. Water rises in the glass, because when the candle is burning, it expands the air inside the glass due to its heat. But when candle wents off, the air is cooled again and it contracts. So, a vacuum is created. That's why the water rises in the glass to fill the vacuum and to balance the air pressure inside and outside the glass.

3. Objects tend to maintain their state of motion or rest unless subjected to an external force. This property is called Inertia. More the mass more the inertia. When sudden brakes are applied, then our body still tends to remain in motion. That's why our body go forward.

White light is shining on a green grape. The grape _____.

Marat540 [252]

The grape absorbs all colors except green, and green light is the

This is a big part of the reason why, whenever somebody looks at
the grape, they remark "Oh look ! The grape is green !"
