Answer:

2 electrons in energy level 6

The amount of energy needed to power a 0.20 kW bulb for one minute would be just sufficient to lift a 2.5 kg object through a vertical distance of approximately 0.49 meters.

To determine the amount of energy needed to power a 0.20 kW bulb for one minute, we first need to calculate the total energy consumption.

The power (P) of the bulb is given as 0.20 kW (0.20 kilowatts). Since power is defined as energy per unit time, we can calculate the energy consumption using the formula:

Energy (E) = Power (P) * Time (t)

Converting the time to seconds (since power is given in kilowatts):

Time (t) = 1 minute = 60 seconds

Substituting the values into the formula:

Energy (E) = 0.20 kW * 60 s

Energy (E) = 12 kilojoules (kJ)

Therefore, the amount of energy needed to power the 0.20 kW bulb for one minute is 12 kJ.

To determine the vertical distance through which a 2.5 kg object could be lifted using this energy, we can use the formula for potential energy:

Potential energy (PE) = m * g * h

Where m is the mass of the object, g is the acceleration due to gravity, and h is the vertical distance.

Rearranging the formula to solve for h:

h = PE / (m * g)

Given that the mass of the object (m) is 2.5 kg and the acceleration due to gravity (g) is approximately 9.8 m/s²:

h = 12 kJ / (2.5 kg * 9.8 m/s²)

h = 0.49 meters (rounded to two decimal places)

Therefore, the amount of energy needed to power a 0.20 kW bulb for one minute would be just sufficient to lift a 2.5 kg object through a vertical distance of approximately 0.49 meters.

As comparison to 15°C water, 85°C water allows the food coloring to spread out more quickly. Due to convection currents, the food coloring will only disperse halfway through the water in each beaker.

Adding a few drops of food coloring to a glass of water causes it to spread out and eventually color the water. Diffusion, a process, is typically to blame for this. The blending of components in a liquid is caused by diffusion.

The food coloring spreads slowly through cold water as it diffuses. Food coloring diffuses more quickly in hot water. Particles travel more quickly when temperatures are higher.

Answer:

I think B) is uncorrect

Explanation:

As A) p=w/t so it's correct relation

C) power depend on time and work as work is distance multiple force so it refer to velocity

D) the powerful mean much work in a few time

In a 4.0-m diameter tank, initial velocity from the 10-cm orifice is 9.92 m/s, taking about 3.57 hours to empty. If draining through a 100-m pipe, initial velocity is 19.02 m/s, taking approximately 11.32 minutes to empty.

(a) To calculate the initial velocity from the tank and the time required to empty the tank, we can use Torricelli's law and the principles of fluid dynamics.

Torricelli's law states that the velocity of fluid flowing out of an orifice is given by the equation v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height of the fluid above the orifice.

Given that the tank is initially filled with water 5 m above the center of the 10 cm (0.1 m) diameter orifice, the height h can be calculated as 5 m + (0.1 m/2) = 5.05 m.

Using g = 9.81 m/s², the initial velocity v is given by v = √(2 * 9.81 * 5.05) = 9.92 m/s.

To calculate the time required to empty the tank, we can use the equation t = V/A, where t is the time, V is the volume of the tank, and A is the cross-sectional area of the orifice.

The volume of the tank can be calculated using V = (π/4) * h * D², where D is the diameter of the tank.

Using D = 4.0 m, the volume V is given by V = (π/4) * 5.05 * 4.0² = 100.71 m³.

The cross-sectional area of the orifice can be calculated using A = (π/4) * d², where d is the diameter of the orifice.

Using d = 0.1 m, the cross-sectional area A is given by A = (π/4) * 0.1² = 0.00785 m².

Thus, the time required to empty the tank is t = 100.71 m³ / 0.00785 m² ≈ 12848 seconds (approximately 3.57 hours).

(b) If the orifice drains into a 100 m long horizontal pipe, we need to consider the frictional losses in the pipe.

To calculate the initial velocity and the time required to empty the tank, we can use the Darcy-Weisbach equation for head loss.

The head loss due to friction in the pipe is given by hL = (f * L * v²) / (2 * g * D), where hL is the head loss, f is the friction factor, L is the length of the pipe, v is the velocity, g is the acceleration due to gravity, and D is the diameter of the pipe.

Given that the friction factor f = 0.0050, the length of the pipe L = 100 m, and the diameter of the pipe D = 0.1 m, we can substitute these values into the equation.

Using the initial velocity v calculated in part (a) as v = 9.92 m/s, the head loss hL is given by hL = (0.0050 * 100 * 9.92²) / (2 * 9.81 * 0.1) ≈ 25.32 m.

The effective head driving the flow is the initial height of the tank minus the head loss, which is 5.05 m - 25.32 m ≈ -20.27 m. The negative sign indicates that the flow is going uphill.

To calculate the time required to empty the tank, we can use the equation t = V / (A * v), where V is the volume of the tank, A is the cross-sectional area of the orifice, and v is the initial velocity considering the head loss.

Using the same values for V and A as in part (a), and v = √(2g * |h_eff|) = √(2 * 9.81 * 20.27) ≈ 19.02 m/s, the time required to empty the tank is t = 100.71 m³ / (0.00785 m² * 19.02 m/s) ≈ 679 seconds (approximately 11.32 minutes).

To answer your question, we need to use the conservation of momentum and conservation of energy principles. Since the collision between the two pendula is elastic, the total momentum and total energy before and after the collision remains the same.

Let's assume that the initial velocity of the bowling ball pendulum is v and the final velocity of both pendula after the collision is v'. According to conservation of momentum,
(m_bowlingball * v) = (m_bowlingball * v') + (m_golfball * v')
where m_bowlingball and m_golfball are the masses of the bowling ball and golf ball pendula respectively.
Similarly, using conservation of energy,
(1/2 * m_bowlingball * v^2) = (1/2 * m_bowlingball * v'^2) + (1/2 * m_golfball * v'^2) + m_golfball * g * h
where g is the acceleration due to gravity and h is the maximum height reached by the golf ball after the collision.
Solving these two equations for v' and h, we get:
v' = (m_bowlingball - m_golfball)/(m_bowlingball + m_golfball) * v
h = (m_bowlingball^2/(m_bowlingball + m_golfball)^2) * (v^2/2g)
Substituting the values given in the problem, we get:
v' = (16/21) * v
h = (256/441) * (v^2/2g)
Therefore, the approximate maximum height that the golf ball reaches after the collision is (256/441) * (v^2/2g), which is approximately 0.58 times the height from which the bowling ball was released.
Note: The exact height reached by the golf ball may vary slightly due to friction and air resistance.

The boy can get as close as 1.25 meters from the right end of the beam without it falling over.

What is Torque?

Torque is a measure of the twisting force that causes rotation or angular acceleration of an object. It is often referred to as the moment of force or the turning effect of force. Mathematically, torque is defined as the cross product of the force vector and the lever arm vector, where the lever arm is the perpendicular distance from the point .

To solve this problem, we need to find the point at which the torque due to the boy's weight is equal and opposite to the torque due to the weight of the beam. This will be the point at which the beam is in equilibrium and will not fall over.

First, we can calculate the weight of the beam using the formula:

weight = mass x gravity

where the mass is 44 kg and gravity is 9.8 m/s^2 (acceleration due to gravity)

weight of beam = 44 kg x 9.8 m/s^2 = 431.2 N

Next, we can calculate the torque due to the weight of the beam about the left post. Since the beam is symmetric, this torque will be halfway between the two posts, or 2.6 m from the left post. The torque is given by:

torque = force x distance

torque due to beam = 431.2 N x 2.6 m = 1121.1 Nm

Now, we can consider the torque due to the boy's weight. Let's assume that the boy's weight can be considered as acting at the midpoint of his position on the beam. If he is x meters from the right end of the beam, then his position on the beam is 2.6 + x meters from the left post. The torque due to his weight is then:

torque due to boy = force x distance

torque due to boy = 24 kg x 9.8 m/s^2 x (2.6 + x) m = 235.2 (2.6 + x) Nm

For the beam to be in equilibrium, the torque due to the boy's weight must be equal and opposite to the torque due to the weight of the beam:

235.2 (2.6 + x) = 1121.1

Solving for x, we get:

x = (1121.1 - 235.2 x 2.6) / 235.2 = 1.25 m

Therefore, the boy can get as close as 1.25 meters from the right end of the beam without it falling over.

To determine the total distance traveled when t = 9.00 s, we need to find the displacement between the initial and final positions of the particle.

Given:
s = t³ - 6t² - 15t + 7

To find the initial position, substitute t = 0:
s(0) = (0³) - 6(0²) - 15(0) + 7
s(0) = 7 ft

To find the final position, substitute t = 9.00 s:
s(9) = (9³) - 6(9²) - 15(9) + 7
s(9) = 729 - 486 - 135 + 7
s(9) = 115 ft

The displacement between the initial and final positions is:
Δs = s(9) - s(0)
Δs = 115 - 7
Δs = 108 ft

Therefore, the total distance traveled when t = 9.00 s is 108 ft.

To calculate the average velocity at time t = 9.00 s, we need to find the instantaneous velocity at that time.

The velocity function is the derivative of the position function:
v = ds/dt

Given:
s = t³ - 6t² - 15t + 7

Differentiating s with respect to t:
v = ds/dt = 3t² - 12t - 15

Substitute t = 9.00 s:
v(9) = 3(9²) - 12(9) - 15
v(9) = 243 - 108 - 15
v(9) = 120 ft/s

Therefore, the particle's average velocity at time t = 9.00 s is 120 ft/s.

To calculate the average speed at time t = 9.00 s, we need to find the total distance traveled divided by the time taken.

Average speed = total distance / time

Given:
Total distance = 108 ft
Time = 9.00 s

Average speed = 108 ft / 9.00 s
Average speed = 12 ft/s

Therefore, the particle's average speed at time t = 9.00 s is 12 ft/s.

Total distance traveled when t = 9.00 s: 108 ft
Particle's average velocity at time t = 9.00 s: 120 ft/s

To make the sounds match in pitch while making sound wave 1 louder than sound wave 2 : Increase the frequency for wave #1 while setting their amplitudes at the same value

The wavelength of a sound wave is inversely proportional to its frequency therefore when the frequency of wave 1 is increased its wavelength decreases with equal proportion.

Since the increase in frequency results to a decrease in wavelength. therefore to make wave 1 louder, both waves we will have to set the amplitude values of the waves at the same amplitude.
