1.00 kg of ice at -24.0°C is placed in contact with a 1.00 kg block of a metal at 5.00°C. They come to equilibrium at -8.88°C.

We can use the principle of conservation of heat to solve this problem. The heat lost by the metal must equal the heat gained by the ice.

The heat lost by the metal is given by

Q1 = m1c1ΔT1

Where m1 is the mass of the metal, c1 is its specific heat, and ΔT1 is the change in temperature.

The heat gained by the ice is given by

Q2 = m2c2ΔT2

Where m2 is the mass of the ice, c2 is its specific heat, and ΔT2 is the change in temperature.

Since the two objects come to thermal equilibrium, we can set Q1 equal to Q2

m1c1ΔT1 = m2c2ΔT2

Solving for c1, we get

c1 = m2c2ΔT2 / (m1ΔT1)

By putting these values we get

c1 = (1.00 kg)(2.06 kJ/kg·K)(-24.0°C - (-8.88°C)) / [(1.00 kg)(5.00°C - (-8.88°C))]

c1 = 0.902 kJ/kg·K

Hence, the specific heat of the metal is 0.902 kJ/kg·K.

Answer

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ... Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. ...

To Find :

Total force acting on \(q_3\) .

Solution :

Total force acting on \(q_3\) is :

\(F_3=\dfrac{kq_1}{r_1^2}+\dfrac{kq_2}{r_2^2}\\\\F_3=k[(\dfrac{1.95\times 10^{-9}}{0.550-0.435})+(\dfrac{3.6\times 10^{-9}}{0.550-0})]\\\\F_3=9.0 \times 10^9 \times [(\dfrac{1.95\times 10^{-9}}{0.550-0.435})+(\dfrac{3.6\times 10^{-9}}{0.550-0})]\\\\F_3=211.52\ N\)

Therefore , force applied on \(q_3\) is 211.52 N .

Its averaged kinetic energy of the a sample containing matter reduces as it continues to cool. The temperature during which particles should theoretically stop moving is absolute zero.

This is because of Heisenberg's uncertainty principle, according to which it is possible to know less about a particle's momentum and more about its position the more information one has about it. The exact position or momentum of a particle could be determined, hence it cannot be entirely halted.

According to Albert Einstein, atoms in stationary molecules can collide and combine to form a single atom.

Answer:Position is an object’s location in relation to a reference point.

Yes. As in the movie theater example, an object can be one unit positive from the reference point and a different object can be one unit negative from the reference point. Both objects are one unit away (the same distance), but they occupy different locations in space because they are in different directions.

Distance is the total amount an object has traveled, while displacement is the shortest distance between the object’s starting and finishing point.

Distance does not have direction. Objects can be one unit away from a point in every direction. However, displacement does have a direction. Displacement is defined as a specific distance in a specific direction.

Answer:

Approximately \(-1.58\; \rm rad \cdot s^{-2}\).

Explanation:

This question suggests that the rotation of this object slows down "uniformly". Therefore, the angular acceleration of this object should be constant and smaller than zero.

This question does not provide any information about the time required for the rotation of this object to come to a stop. In linear motions with a constant acceleration, there's an SUVAT equation that does not involve time:

\(v^2 - u^2 = 2\, a\, x\),

where

The angular analogue of that equation will be:

\((\omega(\text{final}))^2 - (\omega(\text{initial}))^2 = 2\, \alpha\, \theta\), where

For this object:

The question is asking for an angular acceleration with the unit \(\rm rad \cdot s^{-1}\). However, the angular displacement from the question is described with the number of revolutions. Convert that to radians:

\(\begin{aligned}\theta &= 76.8\; \rm \text{revolution} \\ &= 76.8\;\text{revolution} \times 2\pi\; \rm rad \cdot \text{revolution}^{-1} \\ &= 153.6\pi\; \rm rad\end{aligned}\).

Rearrange the equation \((\omega(\text{final}))^2 - (\omega(\text{initial}))^2 = 2\, \alpha\, \theta\) and solve for \(\alpha\):

\(\begin{aligned}\alpha &= \frac{(\omega(\text{final}))^2 - (\omega(\text{initial}))^2}{2\, \theta} \\ &= \frac{-\left(39.1\; \rm rad \cdot s^{-1}\right)^2}{2\times 153.6\pi\; \rm rad} \approx -1.58\; \rm rad \cdot s^{-1}\end{aligned}\).

The cost of operation for an A.C for 10 hours per day for a month will be 71,100 francs.

Power is the amount of energy transferred or converted per unit time. The unit of power is the watt, equal to one joule per second. Power is a scalar quantity.

Cost of operation for 10 hours a day;

Daily consumption = 3kW x 10 hours

Daily Consumption = 30kW

Since 1kWH = 79 francs;

Daily consumption amount = 30 x 79 francs

Daily consumption amount = 2,370 francs

Therefore, the monthly consumption (using 30days) will be;

2,370 francs x 30 = 71,100 francs

In conclusion, 71,100 francs will be spent in a month (30 days) to run the 3kW rated A.C for 10 hours a day at 1kWH.

The Moon's gravity is less than Earth's.

STEP-BY-STEP EXPLANATION:

When you jump, you fall back to the ground. Apples or leaves also fall: we are all attracted to the Earth. It is the terrestrial attraction due to the force of gravity.

The force of gravity also exists on the Moon. But since the Moon is smaller than the Earth, the attraction felt on the Moon is smaller than the Earth's attraction.

As the gravity is less, you can do things such as the one shown in the image.

As the force of attraction is less, the weight is less on the Moon, which can cause things that would be impossible on Earth.

ANSWER and EXPLANATION

The relationship between the motion of the magnet and the current produced can be described by using Faraday's law. It states that:

This law implies that when a coil is in the presence of a changing magnetic field (which may be due to a moving magnet), an electric current is produced in the coil. It is the same when the coil is moved relative to the magnetic field due to the magnet.

The faster the magnetic moves, the greater the magnitude of the current produced, which also means that if there is no motion of the magnet, the current is 0.

That is the relationship between the motion of the magnet and the current produced.

Explanation:

A force of 1.5 x 10⁴ N must be applied to the small piston to support the weight of the car.

The hydraulic lift works on the principle of Pascal's law, which states that pressure applied to an enclosed fluid is transmitted uniformly throughout the fluid and acts with equal force on all surfaces of the container. Therefore, the pressure applied to the small piston will be transmitted to the large piston and support the weight of the car.

The pressure applied to the fluid is given by the formula:

pressure = force / area

Since the area of both pistons is the same, the pressure applied to the fluid will be the same on both pistons. Therefore, we can write:

pressure = force on small piston / area of small piston = force on large piston / area of large piston

We know the area of both pistons, so we can rearrange this equation to solve for the force on the small piston:

force on small piston = pressure x area of small piston

The force on the large piston is equal to the weight of the car, which is 1.5 x 10⁴ N. The pressure applied to the fluid is the same on both pistons, so we just need to calculate the pressure using the formula:

pressure = force on large piston / area of large piston

pressure = (1.5 x 10⁴ N) / (0.50 m²) = 3.0 x 10⁴Pa

Now we can calculate the force on the small piston using the formula we derived earlier:

force on small piston = pressure x area of small piston

force on small piston = (3.0 x 10⁴Pa) x (0.50 m²) = 1.5 x 10⁴ N

Therefore, a force of 1.5 x 10⁴ N must be applied to the small piston to support the weight of the car.
