The leg's force forward on the foot= 500NThe foot's force forward on the ball= 500N
The ball's force back on the foot= 500N
What is the net force on the ball?
What is the net force on the foot?

Answers

Answer 1

Answer:
There's so much going on here, in a short period of time.

Before the kick, as the foot swings toward the ball . . .

-- The net force on the ball is zero. That's why it just lays there and
does not accelerate in any direction.

-- The net force on the foot is 500N, originating in the leg, causing it to
accelerate toward the ball.

During the kick ... the 0.1 second or so that the foot is in contact with the ball ...

-- The net force on the ball is 500N. That's what makes it accelerate from
just laying there to taking off on a high arc.

-- The net force on the foot is zero ... 500N from the leg, pointing forward,
and 500N as the reaction force from the ball, pointing backward.

That's how the leg's speed remains constant ... creating a dent in the ball
until the ball accelerates to match the speed of the foot, and then drawing
out of the dent, as the ball accelerates to exceed the speed of the foot and
draw away from it.

Answers

Answer:

B. Precipitation.

Explanation:

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow.

Answer:

Precipitation

Explanation:

Precipitation occurs when water vapour in the atmosphere condenses and falls back to the earth as rainfall or precipitation. Water vapour is gaseous, when it is cooled, it condenses to the liquid state. Hence precipitation has to do with cooling of water vapour that escapes from the earth surface. This cooling occurs in the cloud and then precipitation follows. See image attached for more details.

Adam's dad takes the parkway to work. It takes him 45 minutes to travel from mile marker 145 where he enters the parkway to his exit at mile marker 98. What is his average speed?1. 62.7 mph

2. 47 mph

3. 1 mph

4. 193.3 mph

Answers

speed=distance/time

see his distance

distance is from 145 to 98
145-98=47 miles

time
60 mins per hour
45 mins =time
time=45/60 hours=0.75 hours

47 miles per 0.75 hours
47/0.75=62.6666666 mph

What will happen to the mass and volume of a block if their is two blocks, three, blocks or four blocks? For example, if the mass of a block is 7g and the volume is 15.625, what will that be if more blocks are added? Please help it is much apreciated!

Answers

To solve this problem, it would be helpful to know the density of 1 block Density is defined as the mass of the substance per volume. From the example given, The density of the block is (7g)/(15.625 units^3) or 0.448 g/units^3. So, if a block is added, the new mass is 7g + 7g = 14 g And the volume 14 g /(density) = 1 unit^3

observation

They utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data

These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.

The wavelength of sound wave is 30 m. Frequency is 7 Hz. What is the wave speed

Answers

Thewave speed will be 210 m/sec. The wave speed is found as the product of the wavelength and frequency of the wave.

What is wavelength?

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The relationship between the wave's wavelength, time, and speed is given as;

Wavelength = speed of wave / time period

$\rm \lambda = (c)/(v) \n\n \rm 30 = (C)/(7 ) \n\n C= 30 * 7 \n\n C=210 \ m/sec$
