total stopping distance is the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It consists of two main components: the thinking distance and the braking distance.

total stopping distance refers to the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It is composed of two main components: the thinking distance and the braking distance.

The thinking distance is the distance the vehicle travels during the driver's reaction time. It is the time it takes for the driver to perceive a hazard and apply the brakes. Factors that can affect the thinking distance include the driver's alertness, distractions, and the speed of the vehicle.

The braking distance is the distance the vehicle travels while the brakes are applied and the vehicle decelerates. It depends on factors such as the speed of the vehicle, the condition of the road, and the efficiency of the brakes.

Therefore, the total stopping distance is influenced by both the thinking distance and the braking distance. It is important for drivers to maintain a safe following distance and be aware of their vehicle's stopping capabilities to ensure they can stop in time to avoid collisions.

Total stopping distance includes b. The distance the car travels during the driver's reaction time

The distance a car travels during the driver's reaction time and the distance it travels while the driver is braking are included in the total stopping distance. It's possible that a driver's foot isn't on the brake when they realise they need to stop the car. The car, for instance, is going at a constant speed.

The moment the driver realises that the vehicle needs to be stopped, his or her foot is moved to the brake pedal. The reaction distance is what we refer to as. The car slows down as soon as the brakes are deployed. The braking distance is the length of time needed to stop. Total stopping distance is calculated by summing reaction distance and braking distance.

The weigh of an object is given by:

P = mg

Solving for m:

m = P/g

We see that for the same weight, if gravity is less, then the amount of mass is greater, because they are inversely proportional. So we conclude that the answer is:

Available options are:

A. –4500 N

B. –2500 N

C. 2500 N

D. 4500 N

Answer:

-4500 N

Explanation:

Given that we have F₁ = 3000N? (force of the barge)

the force of the tugboat is F '

To pull the barge, the force of the tugboat must be greater than or equal to the force of the barge.

Hence, according to Newton's third law which states that for every action or force in nature, there is an opposite reaction.

Therefore considering the available option the correct answer is "- 4500N, " this is because it is greater than the force of the barge and it's in opposition to the force exerted.

Answer:

The answer is -4500 N

Explanation:

If energy is conserved, then initial (PE + KE) = final (PE + KE). So, the correct option is A.

The law of conservation of energy states that, energy can neither be created nor be destroyed, but can be transformed from one form to another.

Here,

According to law of conservation of energy,

The total energy of an isolated system remains constant. That means, the total energy of the system in the initial state will be same as that in the final state.

The total mechanical energy is the sum of kinetic energy and potential energy.

TE = KE + PE

Therefore, the energy to be conserved in the system,

Initial TE = Final TE

So, Initial (KE + PE) = Final (KE + PE)

Hence,

If energy is conserved, then initial (PE + KE) = final (PE + KE).

Answer:

B. The refridgerant

Explanation:

this allows the refrigerant to absorb or release heat

When a block slides on a frictionless horizontal surface, two forces of equal magnitude, F, act on it. These forces can be explained using Newton's laws of motion.

According to the first law, an object will continue moving with a constant velocity unless acted upon by a net external force. In this case, the block is initially at rest, so the net force acting on it is zero. However, when the forces of magnitude F are applied, there is a net external force acting on the block, causing it to accelerate. This acceleration is described by the second law, which states that the net force acting on an object is equal to its mass multiplied by its acceleration. Therefore, the block will experience an acceleration when the forces of magnitude F are applied to it.

The given assertion 'In a series circuit, the current is constant throughout the electric circuit' is correct but the reason 'All electric devices need equal currents to operate properly' is incorrect.

A circuit is said to be connected in series when the same current flows through all the components in the circuit. The current in these circuits only travels along one route.

A higher total voltage is produced by series-connected cells than by single cells. Voltage increases if the number of cells increases. Series circuits do not overheat easily.

All the electrical devices do not require equal amount of current for their functioning. For example, an electric heater and an electric fan do not require the same amount of current.

In a series combination, if one component fails, all other components stop working.

Series connection is not suitable for domestic circuits.

Velocity is vector quantity because it has both magnitude and direction.

Explanation:

velocity is a vector quantity because the person always returns to the original position,the motion would never result in a change in a position.

Main answer:

The separation between the slits on the diffraction grating is 0.001 cm.

Supporting answer:

The diffraction grating has 1000 lines per cm, which means that there are 1000 slits per cm. The separation between adjacent slits is therefore:

d = 1 cm / 1000 = 0.001 cm

We can use the grating equation to determine the angles at which the light diffracts:

d(sin θ) = mλ

where d is the slit separation, θ is the diffraction angle, m is the order of the diffraction maximum, and λ is the wavelength of the light.

We can rearrange this equation to solve for the diffraction angle:

sin θ = mλ/d

For the first-order maximum, m = 1. Plugging in the given values, we get:

sin θ = (1)(600 nm)/(0.001 cm) = 0.6

Taking the inverse sine of both sides, we get:

θ = sin^(-1)(0.6) = 36.9°

Now that we know the diffraction angle, we can use trigonometry to find the distance between adjacent diffraction maxima on the screen. The distance between adjacent maxima is given by:

y = l*tan(θ)

where y is the distance between adjacent maxima on the screen, and l is the distance between the grating and the screen.

Plugging in the given values, we get:

y = 2 m * tan(36.9°) = 2.6 m

Therefore, the distance between adjacent maxima on the screen is 2.6 m.

It's important to note that diffraction gratings are an important tool for studying the properties of light and other wave phenomena.

Answer:

Im pretty sure its kingdom

Explanation:

I have a test with the same question and I got it right putting the answer as kingdom.

The currents after a long time are:

I₁ = 0 (since the circuit is open)

I₂ = (eR₃)/(R₂R₃ + L)

I₃ = - (I₂*R₂)/R₃ = -(e/(R₂ + L/R₃))

When the switch is closed for a long time, a steady-state is reached, and the inductor behaves as a short circuit. Using Kirchhoff's voltage law (KVL) in the outer loop of the circuit,

e = I₂R₂ + I₃R₃ --- (1)

Using KVL in the inner loop of the circuit,

I₂R₂ = I₃R₃ + L*dI₃/dt --- (2)

After the switch is reopened, the inductor will oppose the change in the current flowing through it, and initially, the current through the inductor will continue to flow in the same direction as before.

Using KVL in the outer loop of the circuit,

0 = I₂R₂ + I₃R₃ --- (3)

Using KVL in the inner loop of the circuit, we have:

I₂R₂ = I₃R₃ + L*dI₃/dt --- (4)

Since the inductor opposes any change in current, the current through it will decrease exponentially with time. Therefore, we can assume that after a long time, the current through the inductor will be zero.

Thus, from equation (3), we get I₃ = - (I₂*R₂)/R₃.

Substituting this value in equation (4) and solving for I₂, we get:

I₂ = (eR₃)/(R₂R₃ + L)

Therefore, the currents after a long time are:

I₁ = 0 (since the circuit is open)

I₂ = (eR₃)/(R₂R₃ + L)

I₃ = - (I₂*R₂)/R₃ = -(e/(R₂ + L/R₃))

Hence, the expressions for the currents after a long time are in terms of the variables e, R₁, R₂, R₃, and L.

Answer:

F. The length of day would be longer

Explanation:

The root-mean-square velocity of an ideal gas is given by:

v_rms = √(3kT/m)

where k is the Boltzmann constant, T is the absolute temperature, and m is the molecular mass of the gas.

Since the gases are at thermal equilibrium, they have the same temperature T. Therefore, the ratio of their root-mean-square velocities is:

vX,rms/vY,rms = √(3kT/mX) / √(3kT/mY)

Canceling the common factors of 3kT in the numerator and denominator, we get:

vX,rms/vY,rms = √(mY/mX)

Substituting the given ratio of molecular masses, we get:

vX,rms/vY,rms = √(mY/9mY) = 1/3

Therefore, the ratio of root-mean-square velocities of the two gases is 1/3, or vX,rms/vY,rms = 1/3.

The ultraviolet (UV) radiations in the stratosphere are primarily absorbed by a layer of gas called the ozone layer.

The ozone (O3) molecules in the ozone layer have the ability to absorb UV radiation, particularly in the UV-C and most of the UV-B regions of the electromagnetic spectrum. When UV radiation interacts with ozone molecules, it can cause the breaking and reformation of ozone bonds, resulting in the absorption of UV energy.

This absorption process is important because it prevents a significant amount of UV radiation from reaching the Earth's surface. It acts as a protective shield against harmful UV rays that can have detrimental effects on living organisms, including increased risk of skin cancer, cataracts, and damage to marine ecosystems.

It's important to note that not all UV radiation is absorbed by the ozone layer. Some UV-B and a majority of UV-A radiation reach the Earth's surface, but they are less harmful compared to the shorter wavelength UV-C radiation that is almost entirely absorbed by the ozone layer.

The volume of one mole of an ideal gas at 25°C and 0.915 kPa is approximately 0.2709 cubic meters.

We can use the ideal gas law equation:

PV = nRT

Where

The provided temperature must first be converted from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 25 + 273.15

T(K) = 298.15 K

Now, we can rearrange the ideal gas law equation to solve for V:

V = (nRT) / P

The pressure (P) is given to us as 0.915 kPa. The ideal gas law, however, calls for pressure to be expressed in Pascals, thus we must convert it:

P(Pa) = 0.915 kPa * 1000

P(Pa) = 915 Pa

Now, we can substitute the values into the equation:

V = (1 mol * 8.314 J/(mol·K) * 298.15 K) / 915 Pa

Calculating the expression:

V ≈ 0.2709 cubic meters

So, the volume of one mole of an ideal gas at 25°C and 0.915 kPa is approximately 0.2709 cubic meters.

Velocity is a fundamental concept that describes the rate of change of an object's position with respect to time. It is a vector quantity, meaning that it has both magnitude and direction. The magnitude of velocity is the speed of an object, while the direction is the path that the object takes as it moves. Velocity is calculated by dividing the displacement of an object by the time it takes to cover that distance.

The displacement is the difference between an object's final position and its initial position. The time interval is usually measured in seconds, and the displacement is measured in meters. The SI unit of velocity is meters per second (m/s). Velocity can be positive or negative depending on the direction of motion. Positive velocity indicates that the object is moving in the positive direction, while negative velocity indicates that the object is moving in the negative direction.

One and a half miles of distance  is required for a train to stop when traveling 50 miles per hour.

Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate.

Rearranging the formula,

Speed = distance / time.

Distance = speed × time.

Time = distance / speed.

Hence,

Distance = Speed × Time

⇒ Distance = 50 × 60 / 2000
