Answer: a. To control all of the people in the community
Explanation:
The sport organization help in bring people of different communities together. It removes any kind of discrimination based on caste, gender, race, and others. People are united in a single team to bring about unity in them. The sport organization does not control the people in the community instead can bring change in their thinking and opinion about people of the other community. The sports activities are recreational in nature, they build social interaction between people of different communities, control good health, make communities safer.

The graph shows the amplitude of a pausing wave over time in secondo (o).
What is the approximate frequency of the wave shown?
A. 0.5 Hz
B. 0.1 Hz
C. 9 Hz
D. 20Hz
Answer:
its B
Explanation:
i just took the test
0.1 Hz the approximate frequency of the wave shown.
What is Frequency?In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.
After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also basic harmonic motion and angular velocity.
The frequency is 2 per second if the period, or time interval, needed to complete one cycle or vibration is 1/2 second; it is 100 per hour if the duration is 1/100 of an hour.
Therefore, 0.1 Hz the approximate frequency of the wave shown.

Explanation:
If a velocity-time graph is horizontal, then acceleration is
a
zero.
b
positive
С
less than 1.

A dolphin can hear sounds with frequencies up to 280 kHz. What is the
speed of sound in water if a wave with this frequency has a wwavelength
of 0.51 cm?
Answer:
1428 m/s
Explanation:
Given that,
The frequency hear by a dolphin, f = 280 kHz
We need to find the speed of sound in water if a wave with this frequency has a wavelength of 0.51 cm.
The formula for the speed in terms of wavelength and frequency is given by :
[tex]v=f\lambda\\\\v=280\times 10^3\times 0.51\times 10^{-2}\\\\v=1428\ m/s[/tex]
So, the speed of sound in water is 1428 m/s.
1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:
Answer:
12125.42 Lbs.
Explanation:
The weight of the elephant is 53,900 N
The given parameters;
mass of the elephant = 5,500 kg
The weight of the elephant is calculated as;
Weight = mg
where;
m is the mass of the elephant
g is acceleration due to gravity = 9.8 m/s²
The weight of the elephant is calculated by substituting the given parameters;
Weight = 5,500 x 9.8 = 53,900 N
Thus, the weight of the elephant is 53,900 N

Explanation:
Everything is made up of blank and all matter is made of blank. There are three basic parts of atom: protons,neutrons, and blank. The blank and blank are located in the center of the atom; this area is called the blank. The electrons are found orbiting around the nucleus in an area we call the blank. They are organized into levels within the electron cloud, and the outermost level is referred to as the blank level.

How do you calculate the magnitude of the resultant force of two
forces acting on an object in the same direction?
Answer:
Two forces that act in opposite directions produce a resultant force that is smaller than either individual force. To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force.
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.

What will be
the gravitational force between
two bodies if the mass of each is doubled and
the distance between them is
is halved?
Answer:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
