Each of the five friends needs to pay £12 to cover the cost of their own meals and contribute towards the birthday person's meal. Using mean allows us to distribute the cost equally among the friends, ensuring a fair division of expenses for the meal.

To determine how much each of the five friends needs to pay, we can use the concept of averages (mean) and divide the total cost by the number of people paying.

In this scenario, the total cost of the meal for 6 people is £12 per person. Since the other 5 friends have decided to pay for the birthday person's meal, they will collectively cover the cost of their own meals plus the birthday person's meal.

To calculate the total cost covered by the five friends, we can subtract the cost of one person's meal (since the birthday person's meal is being paid by the group) from the total cost. The cost of one person's meal is £12.

Total cost covered by the five friends = Total cost - Cost of one person's meal

= (£12 x 6) - £12

= £72 - £12

= £60

Now, to find out how much each of the five friends needs to pay, we divide the total cost covered by the five friends (£60) by the number of friends (5).

Amount each friend needs to pay = Total cost covered by the five friends / Number of friends

= £60 / 5

= £12

Answer:

333.5 MJ

Explanation:

ΔV = m·g·Δh

     = 8500 · 9.81 · (15000-11000)

     = 8500 · 9.81 · 4000

     = 333 540 000

     ≈ 333.5 ·10⁶J = 333.5 MJ

The change in potential energy is 333.5 MJ

Potential energy is defined as the energy possessed by an object because of its position relative to other objects, tension within itself, its electric charge, or other factors. Any object that is raised above its rest position has energy stored in it, so it is called potential energy because it has the potential to do work when released.

It can be expressed as:

P.E.= mgh

where, m is the mass of an object measured in grams 'g'

g is the acceleration due to gravity which is \(9.8 m/s^2\)

h is the height measured in meter 'm'

Here,

the given information is

m= 8500kg

Δh= \(h_2 - h_1\) = 15000-11000 = 4,000m

So, P.E. = 850 x 9.8 x 4000 = 333 540 000=  333.5 ·10⁶J = 333.5 MJ

Thus, the change in potential energy is 333.5 MJ

The net work done per cycle for 1.00 mol of gas initially at 0°C is 4.88 kJ.

An isothermal process is a thermodynamic process in which the temperature of the system remains constant, while other state variables such as pressure and volume may change. An adiabatic process is a thermodynamic process in which there is no exchange of heat between the system and its surroundings, while other state variables such as pressure and volume may change.

a) The net work done by the gas per cycle is equal to the area enclosed by the cycle on the PV diagram. From the given figure, the cycle can be divided into two parts: the first part is an isothermal expansion from volume V0 to volume 5V0 and the second part is an adiabatic compression from volume 5V0 to volume V0.

For the isothermal expansion, the pressure decreases from P0 to P0/4. Using the equation for the work done during an isothermal process, the work done by the gas during this part of the cycle is:

W1 = nRT0 ln(5) = 4RT0 ln(5)

For the adiabatic compression, the pressure increases from P0/4 to P0. Using the equation for the work done during an adiabatic process, the work done by the gas during this part of the cycle is:

W2 = (P0V0^m/P0/4*(5V0)^m)^(1 - m)/1-m - (P0/4*(5V0)^m/P0/4)^(1 - m)/1-m = 4P0V0/3(1 - 1/5^(4/5))

The net work done by the gas per cycle is the sum of the work done in each part of the cycle:

W = W1 + W2 = 4RT0 ln(5) + 4P0V0/3(1 - 1/5^(4/5))

b) Since the cycle is closed, the net energy added to the system per cycle must be equal to the net work done by the gas per cycle:

Q = W = 4RT0 ln(5) + 4P0V0/3(1 - 1/5^(4/5))

c) To obtain a numerical value for the net work done per cycle for 1.00 mol of gas initially at 0°C, we need to substitute the appropriate values for R, T0, P0, V0, n, and m. Assuming the gas is an ideal gas, R = 8.314 J/mol K. At 0°C (273 K), the pressure of 1.00 mol of gas in a volume of V0 = 22.4 L (molar volume of ideal gas at STP) is P0 = 1 atm. Therefore,

W = 4(8.314 J/mol K)(273 K) ln(5) + 4(1 atm)(22.4 L)/3(1 - 1/5^(4/5))) = 4.88 kJ

Therefore, the net work done per cycle for 1.00 mol of gas initially at 0°C is 4.88 kJ.

Answer: False

Explanation:

because according to universal law of gravitation, every object attracts every other object in the universe.

according to the newton's third law, for every action there is equal and opposite reaction.

So, both the saturn and pan exerts same force on each other

But from the newton's second law we have, F = ma   &   a = F/m

so, from the above equation acceleration produced by pan is high compared to the acceleration produced by saturn.

Therefore, acceleration produced by saturn is lower than the acceleration produced by pan

but force exerted by saturn is equal to the force exerted by pan

So, the answer is false

Hope it helped u,

pls mark as the brainliest

^_^

The statement is false. Saturn does not exert a much greater force on the moon Pan than Pan exerts on Saturn.

Newton's law of gravitation states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

According to Newton's third law, there is an equal and opposite response to every action. As a result, both Saturn and Pan exert the same force on one another.

But, according to Newton's second law,

F = ma

a = F/m.

As a result of the preceding equation, the acceleration generated by the pan is greater than that caused by Saturn. As a result, the acceleration generated by Saturn is less than that produced by Pan.

So that the power exerted by Saturn is equivalent to that of Pan.

Hence the statement is false.

Answer:

acceleration = 16 m/s²

Explanation:

According to Newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it keeping the mass of the object constant.

Mathematically,

F ∝ a

It means that When there is no net force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions. When the net force is increased or decreased by a factor of X, then acceleration also increased or decreased by a factor of X respectively according to Newton's 2nd law of motion. In our case, net force increased by a factor of 2, So acceleration must also increased by a factor of 2.

F = ma

F = 8m N

2F = 16m N

So,

acceleration = 16 m/s²

The pressure exerted by a rectangular block on the ground is 8 Pascal (Pa) when its weight is 320 N and its dimensions are 4 meters by 10 meters. The greatest pressure occurs when the block is vertically placed at 20 Pa, while the least pressure occurs when it is horizontally placed at 8 Pa.

To calculate the pressure exerted by the rectangular block on the ground, we need to consider the formula for pressure:

Pressure = Force / Area

Given that the weight of the block is 320 N and the dimensions of the block are 4 meters by 10 meters, we can calculate the area of the block in contact with the ground. In this case, it is the length multiplied by the width of the block.

Area = length * width

Area = 4 meters * 10 meters

Area = 40 square meters

Now, we can calculate the pressure exerted by the block on the ground:

Pressure = 320 N / 40 square meters

Pressure = 8 N/m^2 (Pascal)

Therefore, the pressure exerted by the rectangular block on the ground is 8 Pascal (Pa).

To determine the greatest pressure and the least pressure that can be exerted on the ground, we need to consider the orientation of the block.

The greatest pressure occurs when the block is placed vertically on one of its smallest faces. In this case, the entire weight of the block (320 N) is concentrated on a smaller area.

The area in contact with the ground is given by the length multiplied by the width of the smallest face.

Area = 4 meters * 4 meters = 16 square meters

Greatest Pressure = 320 N / 16 square meters = 20 \(N/m^2\)(Pascal)

The least pressure occurs when the block is placed horizontally on one of its largest faces. In this case, the weight of the block is distributed over a larger area.

The area in contact with the ground is given by the length multiplied by the width of the largest face.

Area = 4 meters * 10 meters = 40 square meters

Least Pressure = 320 N / 40 square meters = 8 \(N/m^2\)(Pascal)

Therefore, the greatest pressure that can be exerted on the ground is 20 Pascal (Pa), and the least pressure is 8 Pascal (Pa).
