The final temperature of the bath water is 25.77 C.

Temperature is a measure of the average kinetic energy of the particles in a substance. It is measured in degrees on the Celsius, Fahrenheit and Kelvin scales. Temperature is an important physical quantity that is used to describe a wide range of phenomena in science, engineering and everyday life. Temperature influences everything from the rate of chemical reactions to the growth of living organisms. Hotter objects have higher temperatures than cooler objects and when two objects of different temperatures come into contact, heat will flow from the hotter to the colder object until both reach the same temperature. This process of heat transfer is known as thermal equilibrium.

The final temperature of the bath water can be calculated using the equation:
Tfinal = (mass1*T1 + mass2*T2) / (mass1 + mass2)
where T is the temperature, mass is the mass of water.
In this case, the mass1 is 5.0 L of water (5.0 kg) at 95 C, and the mass2 is 60 L of water (60 kg) at 20 C. So the equation becomes:
Tfinal = (5.0 kg*95 C + 60 kg*20 C) / (5.0 kg + 60 kg)
Tfinal = (475 kg*C + 1200 kg*C) / (65 kg)
Tfinal = (1675 kg*C) / (65 kg)
Tfinal = 25.77 C
Therefore, the final temperature of the bath water is 25.77 C.

The bulb will use 584 kW per year.

An electronic bulb is a small and simple light source that uses a wire filament to glow when electricity is applied.

The filament, which is a coiled thin wire, is made of tungsten.

The filament is enclosed in a ball-shaped glass socket and is connected by copper and lead wires attached to the base of the lamp.

The wires and filament are enclosed in a glass bulb that is filled with an inert gas such as argon.

Thin glass is used to make the bulb, which prevents air from reaching the filament and protects it from burning.

Conversion of watts to kilo-watts

1 Watts = 0.001 kW

400 Watts = 0.4 kW

Average working of the bulb = 4 hours

a heat engine operates in a carnot cucl4 between 80 c and 350 c it absorbs 21000 heat per cycle from a hot reservoir.

Maximum power output of the engine = (21000 J/s) / (350-80) C) = 215.79 W.

An engine is a machine designed to convert one form of energy into mechanical energy. It is most commonly used to convert energy produced from burning fuel into rotational energy used to power a vehicle, machine, or device.

The amount of heat expelled in each cycle = 21000 J - (215.79 W x (350-80) C) = 20,838.21 J

The maximum power output of the Carnot cycle engine is determined by the temperature difference between the hot and cold reservoirs. The power output of the engine is equal to the amount of heat absorbed by the engine (21000 J) divided by the temperature difference (350-80 C).

To find the maximum speed the car can travel without slipping, you can use the formula:

v = sqrt(μ * g * r)

where v is the maximum velocity, μ is the coefficient of friction, g is the acceleration due to gravity (9.8 m/s^2), and r is the radius of the turn.

Plugging in the given values, you get:

v = sqrt(0.60 * 9.8 m/s^2 * 75 m) = sqrt(45.9 m^2/s^2) = 6.8 m/s

The final velocity of the block can be calculated by dividing the force by the mass and multiplying by the distance, which yields a final velocity of 16 m/s.

Velocity is a measure of how fast an object is moving, or how fast it changes its position. It is expressed as distance per unit of time and is typically represented in m/s, km/h, or mph. Velocity is a vector quantity, meaning it has both magnitude (a numerical value) and direction. Velocity can be determined by measuring the speed of an object and the direction in which it is moving. It is important to consider velocity when calculating the motion of an object, as it can affect the final position of the object.

The final velocity of the block can be calculated using the equation of motion, which states that the change in momentum of an object is equal to the applied force multiplied by the time over which it is applied. Since the block starts from rest, its initial momentum is zero. Therefore, the final velocity of the block can be calculated by dividing the force by the mass and multiplying by the distance, which yields a final velocity of 16 m/s.

Given:

The mass of the block, m = 5 kg,

The horizontal force, F = 80 N,

Firstly, acceleration (a) = F/m

or, a = 80/5

or, a = 14 m/sec²

Next, we know, v² = u² + 2as

or, v² = 0 + (2 × 14 × 5)    [the block starts from rest, so u = 0]
