Explanation:
(i thought you could find this in google)
Answer:
Socialism is a political, social, and economic philosophy encompassing a range of economic and social systems characterized by social ownership of the means of production. ... Social ownership can be public, collective, cooperative, or of equity. Socialism is an economic and political system. It is an economic theory of social organization. It states that the means of making, moving, and trading wealth should be owned or controlled by the workers. This means the money made belongs to the workers who make the products, instead of groups of private owners.Socialist government is a form of government in which the means of production are owned by the government of the country. Social systems in this form of government are the ones are divided into the market and the non market forms. The means of transportation are controlled by the government here.
A 0,34-kg volleyball is flying west at 1,98 m/s when it strikes a stationary 0,60-kg basketball dead centre. The volleyball rebounds east at 0,79 m/s. What will be the velocity of the basketball immediately after impact? Choose the east direction as positive.
Explanation:
use the law of conservation of momentum
M1U1+M2U2=M1V1+M2V2
m-mass
u-initial velocity
v-final velocity
1-volleyball
2-basket ball dead center
so using the above formula
0.34×1.98+0.64×0=0.34×0.79+0.64×V2
to get
0.6732+0 = 0.2686+0.64V2
0.4046=0.64V2
divide both sides by 0.64 to get V2 which is the final velocity of basketball
0.6322m/s=V2
The final velocity of the basketball after the impact is 1.643 m/s west.
The given parameters;
mass of the volleyball, m = 0.34 kginitial velocity of the volleyball, u₁ = 1.98 m/smass of the stationary basketball, m₂ = 0.6 kgfinal velocity of the volleyball, v₁ = 0.79 m/sThe final velocity of the basketball after the impact is calculated by applying the principle of conservation of linear momentum;
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.34(-1.98) + 0.6(0) = 0.79(0.34) + 0.6(v₂)
-0.673 = 0.316 + 0.6v₂
-0.989 = 0.6v₂
[tex]v_2 = \frac{- 0.989}{0.6} \\\\v_2 = -1.643 \ m/s\\\\v_2 = 1.643 \ m/s \ west[/tex]
Thus, the final velocity of the basketball after the impact is 1.643 m/s west.

Answer:

A
Explanation:
17. The weight of an object on a given planet can be found by using the formula W = mg, where W is the weight of the object measured in newtons, m is the mass of the object measured in kilograms, and g is the acceleration due to gravity on the planet measured in meters per second squared. An object on Earth has a weight of 150 newtons. If the acceleration on earth is 9.8 m/sec?, on Mercury it is 3.6, on Saturn it is 11.1 and on Jupiter it is 26, on which planet would the same object have an approximate weight of 170 newtons?
Answer:
Saturn
Explanation:
W = mg
150 N = m (9.8 m/s²)
m = 15.3 kg
W = mg
170 N = (15.3 kg) g
g = 11.1 m/s²
The planet is Saturn.
Explain why there is a delay between the arrival of the sound transmitted through the steel pipe and the sound transmitted by the air in the pipe.
Answer: RATE ME AND MAKE ME BRAININESS AND THANK ME
Explanation:Sound waves are pressure waves that travel through Earth's crust, water bodies, and atmosphere. Natural sound frequencies specify the frequency attributes of sound waves that will efficiently induce vibration in a body (e.g., the tympanic membrane of the ear) or that naturally result from the vibration of that body.
Sound waves can potentiate or cancel in accord with the principle of superposition and whether they are in phase or out of phase with each other. Waves of all forms can undergo constructive or destructive interference. Sound waves also exhibit Doppler shifts—an apparent change in frequency due to relative motion between the source of sound emission and the receiving point. When sound waves move toward an observer the Doppler effect shifts observed frequencies higher. When sound waves move away from an observer the Doppler effect shifted observed frequencies lower. The Doppler effect is commonly and easily observed in the passage of planes, trains, and automobiles.
The speed of propagation of a sound wave is dependent upon the density of the medium of transmission. Weather conditions (e.g., temperature , pressure, humidity , etc.) and certain geophysical and topographical features (e.g., mountains or hills) can obstruct sound transmission. The alteration of sound waves by commonly encountered meteorological conditions is generally negligible except when the sound waves propagate over long distances or emanate from a high frequency source. In the extreme cases, atmospheric conditions can bend or alter sound wave transmission.
The speed of sound in steel is about 17 times as fast as it's speed in air.
Naturally, when a sound starts out at one end of a pipe, it reaches the other end thru the steel before it reaches the other end thru the air in the pipe.
The longer the pipe is, the longer will be the delay between the arrival of the two sounds at the other end.

A student walks to the right 25-m along the 800 hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. Calculate the average speed and the average velocity
Answer:
Explanation:
Total distance covered = 25 + 15 = 40 m
Total time = 15 + 8 = 23 s
Average speed = total distance covered / total time
= 40 / 23
= 1.74 m / s
Total displacement = 25 - 15 = 10 m
Total time = 15 + 8 = 23 s
Average velocity = total displacement / total time
= 10 / 23
= .434 m / s to the right .
The average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left).
Given:
Distance to the right = 25 m
Time taken to the right = 15 s
Distance to the left = 15 m
Time is taken to the left = 8.0 s
To calculate the average speed and average velocity, we need to use the following formulas:
Average speed = Total distance traveled ÷ Total time taken
Average velocity = Displacement ÷ Total time taken
Calculate the total distance traveled:
Total distance = Distance to the right + Distance to the left
Total distance = 25 + 15 = 40 m
Calculate the total time taken:
Total time = Time taken to the right + Time taken to the left
Total time = 15 + 8.0 = 23 s
Calculate the average speed:
Average speed = Total distance ÷ Total time
Average speed = 40 ÷ 23 = 1.74 m/s
Calculate the displacement:
Displacement = Final position - Initial position
Displacement = (-15 ) - 25 = -40 m
Calculate the average velocity:
Average velocity = Displacement ÷ Total time
Average velocity = -40 ÷ 23 ≈ -1.74 m/s
So, the average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left). The negative sign in the average velocity indicates that the student's net direction is to the left.

If a bullet with an acceleration of 1.5 m/s2 takes 2 seconds to leave the muzzle of a rifle (starts at rest), what was the length of the rifles barrel?
Answer:
The length is [tex]D =3 \ m [/tex]
Explanation:
The velocity of the bullet is mathematically evaluated as
[tex]v = a * t [/tex]

d. 9.8 m/s
e. 17.5 m/s
Given :
Height from which rock is dropped, h = 17.5 m.
Initial velocity, u = 0 m/s.
To Find :
Speed does the rock strike the water.
Solution :
We know, by equation of motion :
[tex]v^2-u^2=2as[/tex] ......( 1 )
Here , a = g = 9.8 m/s² ( Acceleration due to gravity )
Putting all given values in 1 , we get :
[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]
Therefore, speed with rock strike the water is 18.5 m/s.
Hence, this is the required solution.

- 2.4cos32 + 4.9cos27 = 2.3306
Resolving into y - component
- 2.4sin32 - 4.9sin27 - 1.6 = - 2.553
The vector sum of the displacement will be
Sqrt( 2.3^2 + 2.6^2) =

A 3.00 kg mass is traveling at an initial speed of 25.0 m/s. What is the
magnitude of the force required to bring the mass to rest in a distance of 62.5m?
Answer:
The magnitude of the force required to bring the mass to rest is 15 N.
Explanation:
Given;
mass, m = 3 .00 kg
initial speed of the mass, u = 25 m/s
distance traveled by the mass, d = 62.5 m
The acceleration of the mass is given as;
v² = u² + 2ad
at the maximum distance of 62.5 m, the final velocity of the mass = 0
0 = u² + 2ad
-2ad = u²
-a = u²/2d
-a = (25)² / (2 x 62.5)
-a = 5
a = -5 m/s²
the magnitude of the acceleration = 5 m/s²
Apply Newton's second law of motion;
F = ma
F = 3 x 5
F = 15 N
Therefore, the magnitude of the force required to bring the mass to rest is 15 N.
