The average force on the puck by the stick is 448 N

To find the average force on the hockey puck, we can use the impulse-momentum theorem:

Impulse = Change in momentum

The impulse on the puck can be calculated as:

Impulse = mass x change in velocity
Impulse = 0.16 kg x (9 m/s - (-5 m/s))
Impulse = 0.16 kg x 14 m/s
Impulse = 2.24 N*s

The change in velocity is negative because the puck is moving in the opposite direction after the impact.

The impulse on the puck is equal to the average force multiplied by the time of contact:

Impulse = average force x time
2.24 N*s = average force x 0.005 s
average force = 2.24 N*s / 0.005 s
average force = 448 N

Therefore, the average force is 448 N.

Because of Earth's motion in its orbit, a synodic month takes about 2.2 days longer than a sidereal month.

Because of Earth's motion in its orbit as the moon circles around it, a synodic month takes longer than a sidereal month.

A synodic month, also known as a lunar month, is the time it takes for the moon to complete a full cycle of phases, from new moon to new moon. This cycle lasts approximately 29.5 days.

On the other hand, a sidereal month is the time it takes for the moon to complete one orbit around the Earth relative to the stars. This period lasts about 27.3 days.

The reason a synodic month takes longer is due to Earth's own motion around the sun. As Earth moves along its orbit, it takes extra time for the moon to catch up to the same phase relative to the sun.

To put it simply, imagine you and a friend are running in circles around a tree. If your friend is running slower than you, it will take them longer to reach a specific point on the tree, even though they are moving at a constant speed.

In summary, because of Earth's motion in its orbit, a synodic month takes about 2.2 days longer than a sidereal month.

Answer:

Approximately \(2.69\; {\rm A}\).

Explanation:

Ensure that all values are measured in standard units. Charge should be measured in coulombs, while time should be measured in seconds:

\(\begin{aligned}t &= 3.0\; {\rm hr} \times \frac{3600\; {\rm s}}{1\; {\rm hr}} = 10800\; {\rm s}\end{aligned}\).

Electric current \(I\) is the rate of flow of electric charge.

In order to find the electric current, divide electric charge \(q\) by the time \(t\) required to transfer these charge. If charge \(q\!\) is measured in coulombs and time \(t\!\) is measured in seconds, the unit of current \(I\)would be amperes:

\(\begin{aligned}I & = \frac{q}{t} \\ &= \frac{29000\; {\rm C}}{10800\; {\rm s}} \approx 2.69\; {\rm A}\end{aligned}\).

A distinction between thermal energy and internal energy is : Thermal energy emphasizes heat flow, whereas internal energy is the grand total of all energies inside a substance. Physicists prefer internal energy. Option(d).

Thermal energy refers to the energy associated with the temperature of a substance or a system. It is related to the kinetic energy of the molecules or particles within the system. Internal energy, on the other hand, encompasses all forms of energy present within a substance, including kinetic energy, potential energy, and the energy associated with the molecular structure.

Physicists generally prefer the term "internal energy" because it encompasses all energy components within a system, whereas "thermal energy" specifically refers to the energy associated with temperature and heat flow. Internal energy is a more comprehensive term that takes into account various types of energy and their interactions within a substance.

The kinetic energy of the electron moving at 6.00 × 10^6 m/s is approximately 1.6347221 × 10^(-18) joules (J).

To calculate the kinetic energy of an electron moving at a given velocity, we can use the formula for kinetic energy:

KE = (1/2) * m * v^2

where:

KE is the kinetic energy,

m is the mass of the electron, and

v is the velocity of the electron.

The mass of an electron (m) is approximately 9.10938356 × 10^(-31) kilograms.

Given the velocity (v) as 6.00 × 10^6 meters per second, we can now calculate the kinetic energy:

KE = (1/2) * (9.10938356 × 10^(-31) kg) * (6.00 × 10^6 m/s)^2

KE = (1/2) * (9.10938356 × 10^(-31) kg) * (3.6 × 10^13 m^2/s^2)

In waste treatment plants, there are several common types of sedimentation tanks .some of the most common sedimentation tanks and their purposes: Primary Sedimentation Tank , Secondary Sedimentation Tank ,Tertiary Sedimentation Tank:

1. Primary Sedimentation Tank: The primary sedimentation tank, also known as a primary clarifier or primary settling tank, is designed to remove settleable solids and heavy particles from wastewater. It allows the heavier particles to settle at the bottom of the tank, forming sludge, while the lighter particles float to the top and are skimmed off. The primary sedimentation tank helps in the removal of large suspended solids and organic matter.

2. Secondary Sedimentation Tank: The secondary sedimentation tank, also called a secondary clarifier or final settling tank, is used in biological treatment processes. It receives the treated wastewater from the biological reactor, such as an activated sludge process or a trickling filter, and allows the remaining suspended solids, microorganisms, and flocs to settle. This tank separates the treated wastewater from the biological sludge or biomass before the water is discharged or subjected to further treatment.

3. Tertiary Sedimentation Tank: Tertiary sedimentation tanks, also known as tertiary clarifiers or polishing basins, are used for additional treatment after the secondary sedimentation tank. These tanks further remove fine suspended solids, residual organic matter, and nutrients, such as phosphorus or nitrogen, from the wastewater. Tertiary treatment is often required to meet strict effluent quality standards before the wastewater is discharged into the environment.

4. Imhoff Tank: An Imhoff tank is a type of sedimentation tank used for the treatment of sludge or sewage solids. It consists of two chambers: an upper chamber for settling and a lower chamber for anaerobic digestion of the settled sludge. The Imhoff tank allows for the natural decomposition of organic solids in the lower chamber, reducing the volume of sludge and producing biogas.

These sedimentation tanks play a crucial role in wastewater treatment by allowing the separation and removal of solids from the wastewater, improving the overall quality of the treated effluent. The specific design and purpose of each tank may vary depending on the treatment process and the requirements of the wastewater treatment plant.

The total distance traveled by the car is 12.25 km To calculate the total distance traveled by the car, we need to use the Pythagorean Theorem as the car is changing direction. This theorem states that for a right-angled triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side.

In this case, we can consider each section of the car's journey as the side of a right-angled triangle. The total distance is the length of the longest side, also known as the hypotenuse. We can calculate this as follows: Distance traveled to the east = 5 km, Distance traveled to the north = 10 km, Distance traveled to the west = 5 km

To calculate the total distance, we need to combine the first two legs of the journey into a single right-angled triangle. We can then use the Pythagorean Theorem to calculate the length of the hypotenuse. The hypotenuse of this triangle represents the distance from the starting point to the point where the car turned west.

Distance traveled to the east and north = √(5² + 10²)

= √(25 + 100)

= √125 = 11.18 km

Now, we can combine this distance with the final leg of the journey, which runs in the opposite direction. We can consider this section as another right-angled triangle and use the Pythagorean Theorem once again to calculate the hypotenuse. Distance traveled to the west = 5 km

Total distance traveled by the car = √(11.18² + 5²)

= √(125 + 25)

= √150

= 12.25 km

Therefore, the total distance traveled by the car is 12.25 km.

Answer:

4200 J/°C/kg

Explanation:

The formula for heat transfer is given by :

Q= m*c*ΔT  where;

Q= heat transferred = 6930 J

m=mass of the liquid = 0.330 kg

c= specific heat capacity=?

ΔT = 25-20 = 5.0°C

Applying the values in the formula as;

Q= m*c*ΔT

6930 = 0.330 * c * 5

6930 = 1.65 c

6930/1.65 = c

4200 = c

c= 4200 J/°C/kg

Answer:

43.3 m/s.

Explanation:

Assuming the potential energy is due to the gravitational potential energy, we can use the conservation of energy to find the kinetic energy:

Total energy = Potential energy + Kinetic energy

Kinetic energy = Total energy - Potential energy

Kinetic energy = 300 J - 40 J = 260 J

However, we need to know the mass of the object to convert the kinetic energy to velocity. We can use the potential energy to find the mass:

Potential energy = mgh

40 J = m(9.81 m/s^2)(300 m)

m = 0.137 kg

Now we can use the kinetic energy to find the velocity:

Kinetic energy = (1/2)mv^2

260 J = (1/2)(0.137 kg)v^2

v^2 = (2*260 J) / 0.137 kg

v = 43.3 m/s (rounded to one decimal place)

Therefore, the kinetic energy is 260 J and the velocity of the object when it reaches the ground is 43.3 m/s.
