It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper

Explanation:

390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C

From the given information,

The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.

The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.

Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

The energy required to heat 600g of iron from 25°C to 60°C is 8,760 Joules. to calculate this, we can use the equation:

Energy = mass × specific heat capacity × temperature change

Given:

Mass (m) = 600g

Specific heat capacity (c) = 0.41 J/g°C

Temperature change (ΔT) = 60°C - 25°C = 35°C

Plugging these values into the equation, we get:

Energy = 600g × 0.41 J/g°C × 35°C = 8,760 Joules.

Therefore, 8,760 Joules of energy is required to heat 600g of iron from 25°C to 60°C.

In the calculation, we use the formula for calculating the energy required to heat a substance: Energy = mass × specific heat capacity × temperature change. We are given the mass of iron (600g), the specific heat capacity of iron (0.41 J/g°C), and the temperature change (35°C). By substituting these values into the equation, we find that 8,760 Joules of energy is needed to heat the iron from 25°C to 60°C.

Mass of silver required = density of silver * volume of silver

volume of silver = surface area of teapot * height of silver layer

volume = 700 cm² * 1 m²/ 10⁴ cm² * 0.133 * 1 m/1000 mm

volume = 9.31 * 10⁻⁶ m³

mass of silver = 10.5 * 10³ kg/m³ * 9.31 * 10⁻⁶ m³

mass of silver = 9.7755 * 10⁻² kg * 1000 g/ 1 kg = 97.755 g

1 mole of Ag⁺ will be discharged by 96500 C of charge

molar mass of silver 108 g/mol

97.755 g of silver will be discharged by = 96500 C * 97.755/108 = 87345.9 C of charge

Explanation:

The value of the normal force is 3.9 x 10² newtons.

The correct answer is option C.

The coefficient of static friction between the crate and the floor is 0.11. The crate just starts moving after the force of 43 N is applied by Mary and Anne. Therefore, the force of friction that acts on the crate is equal to the maximum value of static friction, which is given by the product of the coefficient of static friction and the normal force.

The force of friction is given by: f = μN

where f is the force of friction, μ is the coefficient of static friction and N is the normal force acting on the crate.

Since the crate just starts moving, the applied force must overcome the maximum force of static friction.

Therefore, we have:

f = μNmax

and F applied = F required to overcome friction

= μNmax= 0.11 N

Thus, the maximum value of the normal force acting on the crate is given by:

Nmax = F/f = 43/0.11 = 390.9 N ≈ 3.9 x 10² N

Therefore, the value of the normal force is 3.9 x 10² newtons.

The correct order of the structures through which inhaled air moves during inhalation is 4, 3, 1, 2 (terminal bronchiole, respiratory bronchiole, alveolar ducts, and alveolus, respectively). The correct option is (c).

The process of inhalation involves the movement of air through a series of structures within the respiratory system, starting from the nose or mouth and ending in the alveoli, where gas exchange occurs.

The terminal bronchioles are the smallest airways in the lungs that are responsible for directing air to the respiratory bronchioles.

The respiratory bronchioles are the site where gas exchange begins to occur, as they contain small air sacs called alveoli. The alveoli are thin-walled structures that are highly permeable to gases and are the site of gas exchange between the lungs and the blood.

The alveolar ducts are a series of narrow tubes that lead to the alveoli and are responsible for transporting air from the respiratory bronchioles to the alveoli.

The alveoli are the final destination for inhaled air and are the site where oxygen and carbon dioxide are exchanged between the lungs and the bloodstream.

It is important to note that this sequence is for inhalation only, and during exhalation, the order of the structures is reversed.

In exhalation, air moves out of the alveoli into the alveolar ducts, then to the respiratory bronchioles, terminal bronchioles, and finally out of the nose or mouth.

True. Energy of motion, or kinetic energy, must be understood and counteracted when driving.

Reducing your speed and always wearing a safety belt will indeed lessen the kinetic energy and potential impact should a collision occur.

Kinetic energy is directly proportional to the mass of an object and the square of its velocity. When driving, the kinetic energy of a vehicle increases significantly as the speed increases.

This means that even a small increase in speed can result in a substantial increase in the vehicle's kinetic energy.

By reducing your speed, you effectively decrease the kinetic energy of your vehicle. This reduction in kinetic energy can significantly impact the outcome of a collision.

A lower kinetic energy means that the vehicle will require a shorter stopping distance and will generate less force upon impact.

Additionally, wearing a safety belt is vital for mitigating the effects of kinetic energy during a collision. Safety belts are designed to restrain occupants and prevent them from being thrown forward or out of the vehicle in the event of a sudden stop or collision.

By wearing a safety belt, the occupants' deceleration is controlled, reducing the risk of severe injuries caused by the abrupt change in kinetic energy.

It's important to note that while reducing speed and wearing a safety belt can help lessen the effects of kinetic energy, they are not the only factors to consider for safe driving.

Other factors, such as maintaining a safe following distance, being aware of road conditions, and obeying traffic rules, also play critical roles in preventing collisions and minimizing the impact of kinetic energy.

The materials that are likely to be good conductors of electric current are Copper, Aluminium and Gold.

Copper, Aluminium, and Gold are the best electrical conductors.

Copper is the most widely used electrical conductor, while aluminium is the second-most commonly used.

Gold is the third-most commonly used electrical conductor.

The amount of electrical current that a conductor can carry is determined by its conductivity.

Resistance is the opposite of conductivity, and it restricts the flow of current through a conductor.

Because resistance generates heat, conductors must have the ability to dissipate heat to prevent it from melting or burning.

In general, materials that are good electric conductors are also good thermal conductors.

Copper, aluminium, and gold are all good electrical conductors and have high thermal conductivity because they can carry electrical current without losing energy in the form of heat.

Answer:

TRUE.

Explanation:

Option a is correct.

F=GMm/R²

where F is the gravitational force or weight

G is the universal constant of gravitation

M is the mass of Earth

m is the mass of the object

R is the distance between the center of the earth and the object

Given,

initial distance R =4000miles

weight at surface of the earth F=400lb

Let the force be F' for a distance R' from earth's center.

Here R' = radius+ height of the tower = R+4000 miles = 4000 + 4000 = 8000 miles.

Since the other terms in the formula remain constant, the new weight F' can be calculated as follows:

F'/F = R²/R'(otherwise the inverse square law in gravitation)

F'/400=(4000)²/(8000)²

F' = 100 lb

The weight of the body on a 4000-mile high tower would still be 400 lbs.

The weight of an object depends on the gravitational acceleration at its location. On the surface of the Earth, the gravitational acceleration is approximately 32 ft/s2. Therefore, a 400 lb body on the Earth's surface would weigh 400 lbs. If the body were placed on a 4000-mile high tower, it would be much farther from the center of the Earth and experience a weaker gravitational pull. The weight of the body would decrease as the square of the ratio of the radii of the tower and the Earth. So, the weight on the tower would be:

Weight on the tower = (400 lb) * (4000 mi/4000 mi)2 = 400 lb * 1 = 400 lb
