The speed of the small stone lodged in the tire's tread is approximately 10.47 m/s, and its acceleration is approximately 219.35 m/s².

We need to find the speed and acceleration of a small stone lodged in the tread of a tire with a 0.500 m radius, rotating at 200 revolutions per minute.

First, let's convert the revolutions per minute (rpm) to radians per second (rad/s):
200 rpm * (2π radians/1 revolution) * (1 minute/60 seconds) ≈ 20.94 rad/s

Now, we can find the linear speed (v) of the stone using the formula:
v = rω, where r is the radius, and ω is the angular velocity in rad/s.
v = 0.500 m * 20.94 rad/s ≈ 10.47 m/s

Next, we'll find the centripetal acceleration (a_c) of the stone using the formula:
a_c = rω²
a_c = 0.500 m * (20.94 rad/s)² ≈ 219.35 m/s²

The increase in power needed for the boat to move through the lake at a constant speed of 12ms is 4.4 kW.

Power can be defined as the amount of work completed in a given amount of time. Watt (W), which is derived from joules per second (J/s), is the SI unit of power.

We know that:

Power = force × speed

For 1st case:

10000 = k × 10 × 10

k = 100

Hence, the increase in power needed for the boat to move through the lake at a constant speed of 12ms is =  100 ( 12² - 10²) watt

= 4400 watt

The radius of the output cylinder is 0.11 m.

Radius of the input cylinder, r₁ = 0.01 m

Input force applied, F₁ = 200 N

Mass of the output cylinder, m₂ = 2500 kg

Since more collisions with the piston occur when the area is increased but the number of molecules per cubic centimetre remains constant, the force is proportional to the area.

Force applied on the output cylinder = Weight of the output cylinder

F₂ = m₂g

F₂ = 2500 x 9.8

F₂ = 245 x 10²N

We know that the force applied on an object is directly proportional to the area of the object.

F ∝ A

So, F₁/F₂ = A₁/A₂

F₁/F₂ = (r₁/r₂)²

200/24500 = (r₁/r₂)²

Therefore, the radius of the output cylinder is,

r₂ = r₁√(24500/200)

r₂ = 0.01 x√122.5

r₂ = 0.01 x 11.06

r₂ = 0.11 m

A ball which is most likely to topple the bowling pin is: 2. the rubber ball.

The law of conservation of momentum states that the total linear momentum of an isolated (closed) system would always remain constant (the same) with respect to time, unless an external force is applied.

Additionally, the law of conservation of momentum states that the total momentum of two interacting objects in an isolated (closed) system would be the same or remain constant, provided no external force is applied.

In this scenario, we can logically deduce that momentum is conserved in the interaction between the large wooden bowling pin and a ball, but more momentum would be transferred from the rubber ball to the bowling pin, rather than from the putty ball to the rubber ball.

In conclusion, the rubber ball is more likely to topple the bowling pin over because it acts as an external force.

The equivalent of a one ounce force in Newtons = 0.278N

Ounce is a unit of mass used in the imperial and US measurement systems. Shorthand: oz. A slice of bread weighs about the same as one ounce. The actual weight is 28.349523125 grammes. In some systems of measurement, such as English engineering units and British gravitational units, an ounce-force is a unit of force.

The ounce-force is equivalent to the force produced by a mass of one ounce in a typical gravitational field. Meanwhile, the SI-derived unit of force is the newton (N). It is equal to the force necessary to accelerate a mass of one kilograms at a rate of one meter per second squared, according to Newton's second law of motion. Consequently, 1 N = 1 kg/m/s2.

Given:

Electrical energy is transformed into thermal energy in the toaster     energy Q = 231 J

The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process. The increase in temperature caused by heating a substance causes these particles to accelerate and collide.

The energy that arises from a heated substance is referred to as thermal energy. The more the substance's thermal energy and the more its particles travel at higher temperatures.

When the block and table are in an elevator moving upward at a constant speed, the magnitude of the normal force (Fn) is equal to the weight (mg) of the block.

This is because there is no net force acting in the vertical direction, so Fn balances out the weight of the block.

If the elevator is moving upward at an increasing speed, the magnitude of the normal force (Fn) will be greater than the weight (mg) of the block. The additional upward acceleration of the elevator requires an additional upward force to accelerate the block. The normal force must be greater than mg to provide this extra force and maintain equilibrium.

Explanation: ):

The wavelength of the sound waves with a constant frequency of 250 Hz traveling through air at STP (Standard Temperature and Pressure) is 1) 0.76 m.

The speed of sound in air at STP is approximately 343 m/s. The relationship between wavelength (λ), frequency (f), and speed of sound (v) is given by the formula:

v = λ * f

Rearranging the formula to solve for λ, we have:

λ = v / f

Substituting the values, we get:

λ = 343 m/s / 250 Hz = 1.372 m

Rounding to the nearest tenth, the wavelength is approximately 0.76 m. Therefore, option 1) 0.76 m is the correct answer.

When you are next to a space shuttle and your buddy of equal mass is moving at a speed of km/h with respect to the ship and collides with you, the speed at which both of you will move with respect to the ship can be determined as follows.If you are stationary next to the space shuttle and your buddy is moving towards you with a velocity of km/h, then the relative velocity between you and your buddy is km/h.the resulting speed with respect to the ship would be the average of your initial velocities.

This means that if you are stationary, your buddy will move with a velocity of km/h relative to you.Now, if you and your buddy hold onto each other after the collision, the velocity of the two of you will combine. Since you both have the same mass, the velocity of the combined system will be the average of your initial velocities. Thus, the speed at which both of you move with respect to the ship will be km/h / 2 = km/h. This is because you and your buddy had equal mass and equal velocities, and you collided and held onto each other. Therefore, the resulting speed with respect to the ship would be the average of your initial velocities.

#SPJ4

Answer:

If it is a true mixture, the mixing enthalpy is negligible, and there is no reaction or phase change, then you can do this using exclusively the temperatures of the individual compounds and their heat capacities. Any other process that takes place needs to be taken into account separately.

The solution can be found by understanding that we’re only using state variables. You can design any complicated process that starts with the starting situation and ends up at the ending situation, and the state variables will be the same. And sometimes a complicated process is easier to calculate than the simple one-step process, like here when mixing multiple components.

One way that will work is to start by bringing all compounds to the lowest temperature of either of the compounds. All but one of the compounds must be cooled down for this; make sure to calculate for each of the components how much energy is released. Now, mix all the components together. In the simplest situation sketched above you can calculate the heat capacity of the mixture by adding all the heat capacities of the components. Use this total heat capacity to calculate how much you can heat up the mixture using the energy you saved in cooling down the components earlier. This will be your desired end situation.

In case there are any phase changes or other processes in between, you need to take the energy needed for those into account too but in very similar ways.
