Two billiard balls move toward each other on a table. The mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. The mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. After the balls collide, they bounce off each other. The number three ball moves off with a velocity of 5 m/s. What is the final velocity and direction of the eight ball? 8. 6 m/s 5. 7 m/s â€"5. 7 m/s â€"8. 6 m/s.

Answers

Answer 1

This question involves the concepts of the law of conservation of momentum and velocity.

The velocity of the eight ball is "5.7 m/s".

According to the law of conservation of momentum:

[tex]m_1u_1+m_2u_2=m_1v_1+m_2v_2[/tex]

where,

m₁ = mass of number three ball = 5 g

m₂ = mass of the eight ball = 6 g

u₁ = velocity of the number three ball = 3 m/s

u₂ = velocity of the eight ball = - 1 m/s (negative sign due to opposite direction)

v₁ = final velocity of the three number ball = - 5 m/s

v₂ = final velocity of the eight ball = ?

Therefore,

(5 g)(3 m/s) + (6 g)(- 1 m/s) = (5 g)(- 5 m/s) + (6 g)(v₂)

[tex]v_2=\frac{34\ g.m/s}{6\ g}\\\\[/tex]

v₂ = 5.7 m/s

Two gravitational forces act on a
given object. How do you determine the total gravita-
tional force acting on the object?

Answers

Answer:

Explanation:

Depends on the location of the two forces.  If they are aligned on the same side of the object, you would simply add.

X -----------F1 -------F2

X is the object. F1 and F2 are both masses which create a gravitational force. They both are the form of Fx = G * m1 * m2 / r^2. The total force is F1 + F2

If they are are on either side of the object, you subtract.

F1 ---------X ---------F2

Fx = F1 - F2

Any other location of F1 and F2 is much more complicated by the use of trigonometry.

how to find velocity of center of mass before and after the collision

Answers

Hey there! I'll try to provide you with my best answer.

Answer: In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

A number line goes from 0 to 30. Closed circles are at 6 and 25. A line is drawn from point 6 to point 25. Ari is swimming a 25-meter race. After swimming 6 meters, she catches up to Amanda in a ratio of 7:3 from the 6-meter mark. At what meter mark does Ari catch up to Amanda? Round to the nearest tenth, if necessary. Ari catches up to Amanda at meters.

Answers

The position on the meter mark where Ari catches up with Amanda is 19.3 m.

The given parameters:

Range of the number line, = 0 to 30Position of the closed circles, = 6 and 25The ratio between the initial position and final position of Ari = 7:3

The distance between 6 m mark and 25 m mark is calculated as follows;

[tex]d = 25 \ m - \ 6 \ m\\\\\d = 19 \ m[/tex]

The distance traveled by Ari before catching up with Amanda is calculated as follows;

total ratio = 7 + 3 = 10

[tex]distance = \frac{7}{10} \times 19 \ m\\\\distance = 13.3 \ m[/tex]

The position of Ari from the 6 m mark is calculated as follows;

[tex]position = 6 \ m \ + \ 13.3 \ m\\\\position = 19.3 \ m[/tex]

Thus, the position on the meter mark where Ari catches up with Amanda is 19.3 m.

The relationship between the number of moles and the volume of gas is determined by the Avogadro's law in this equation.

Avogadro's law:

It states that at constant temperature and pressure, gases with same volume has the same number of molecules.

For an ideal gas with with constant  temperature and pressure, the volume of the gas is directly proportional to the amount or number of molecules.

Charle's law states that at constant pressure, volume (V) and temperature (T) are directly proportional.Boyle's law states that at constant temperature, the volume of gas is inversely proportional to the gas pressure.Gay-Lussac's law states that pressure (P) and absolute temperature (T) of the gas are directly proportional.

Therefore, the relationship between the number of moles and the volume of gas is determined by the Avogadro's law in this equation.

Ans- resistance by 9975Ω

By adding an external resistor of  287.5 Ω in series with the meter, the conversion of the moving coil meter to have a full-scale deflection for a current of 50 mA.

Current sensitivity (S) is the ratio of full-scale deflection current to full-scale deflection voltage.

S = I(fsd) / V(fsd).

S = 4.0 / 25

S = 0.16 mA/Ω

Desired current sensitivity for 50 mA (S(new)) = 50 mA / V(fsd)

(S(new)) = 50 mA / V(fsd)

(S(new)) =  50  / 0.16

(S(new)) =  312.5 Ω

Add External Resistor:

Add an external resistor (R(ext)) in series with the meter. Calculate R(ext) as the difference between R(new) and the internal resistance of the meter

(R(internal) = 25 Ω:

R(ext) = R(new) - R(internal)

R(ext) = 312.5 Ω - 25 Ω

R(ext) = 287.5 Ω

By adding an external resistor of  287.5 Ω in series with the meter, the conversion of the moving coil meter to have a full-scale deflection for a current of 50 mA. This will achieve the desired result.
