You kick a ball with a speed of 14 m/s at an angle of 51 degrees. How far away does the ball land?A. 21.3 m
B. 19.6 m
C. 1.8 m
D. 3.96 m

Answers

Answer 1
Answer:

Answer: The ball will land at 19.6 m

Explanation:

To calculate the horizontal range of the ball, we use the formula:

R=(v^2\sin 2\theta)/(g)

where,

v = velocity of the ball = 14 m/s

\theta = angle at which the ball is thrown = 51°

g = acceleration due to gravity = 9.8m/s^2

Putting values in above equation, we get:

R=((14)^2* \sin (2* 51))/(9.8)\n\nR=19.6m

Hence, the ball will land at 19.6 m
Answer 2
Answer: d may be the correct answer because speed is very low so ball should cover less distance  but angle is not very high so it can cover little much distance

In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge 2e and mass 6.64 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is in a very small nucleus, with electrons in orbit around it. Assume an alpha particle, initially very far from a stationary gold nucleus, is fired with a velocity of 1.50 107 m/s directly toward the nucleus (charge 79e). What is the smallest distance between the alpha particle and the nucleus before the alpha particle reverses direction?

Air is forced through the water to remove gases is called?

Answers

The process through which air is forced through water to remove gases is called aeration. Aeration is often used as a major step in water treatment plants to remove unwanted gases such as carbon dioxide, odors, and other impurities in water. The process also allows dissolved metals such as iron to oxidize.

Answer:

d. aeration

How far can a bike rider traveling at 5.2 m/s go in 15 seconds

Answers

If he's traveling at 5.2 m/s, then he covers
5.2 meters in the 1st second
5.2 meters in the 2nd second
5.2 meters in the 3rd second
5.2 meters in the 4th second
.
.
.
.
5.2 meters in the 14th second, and
5.2 meters in the 15th second.

He covers 5.2 meters 15 times in 15 seconds.
To find the total distance, you could write down 5.2 meters
15 times and add them all up.  Or you could use the newly-
discovered, labor-saving process called 'multiplication' to do
the same thing.  With multiplication, it can be done in one line:

        (5.2 m/s) x (15 sec)  =  78 meters .
