The force of the car increases because it is proportional to the acceleration of the object (as stated in the second law). If the object accelerates then the force accelerates, if the acceleration decreases then the force decreases. Same for mass. The force of the car would have changed from 315 newtons of force to 1,260 newtons of force.
<span>Bakers making fruit pies face the problem of the fruit juices running out into the oven and having a soggy crust. An ingenious way of preventing this is to put a paper cone made of thick brown paper in the hole at the center of the top
crust as you put the pie in the oven. When the fruit juice boils, it rises into this funnel and then goes back down into the pie, preventing the juice from overflowing all over the crust. Pinching together the upper and lower crusts will prevent the juice from seeping out from the edges.</span>
Answer:
They all hit at the same time
Explanation:
Let the time of flight is T.
The maximum height is H and the horizontal range is R.
The formula for the time of flight is
..... (1)
Te formula for the maximum height is
.... (2)
From equation (1) and (2), we get


here, we observe that the time of flight depends on the maximum height and according to the question, the maximum height for all the three balls is same so the time of flight of all the three balls is also same.
Answer: That would be the first step of the scientific method. After that, the scientist would research the problem and form a hypothesis
Liquid is not a solid object so make sure you define them
