Explanation:

Around 3 p.m., when the sun is sufficiently low in the sky, more heat is lost than is received.

Even though the sun's beams are most direct around noon, the afternoon is the warmest part of the day because air temperatures close to the earth's surface will continue to rise as long as incoming solar radiation outweighs outgoing longwave earth radiation.

Around 3 p.m., it gets the warmest. When the sun is at its zenith in the sky, or after midday, heat continues to accumulate as long as more heat is entering the earth than is leaving. When the sun is low enough in the sky, around 3 p.m., more heat is lost than is gained.

Many people believe that noon is when it gets the warmest. We receive the maximum energy from the sun at noon, which may make it feel hotter. But during the day, Earth is accumulating heat or energy from incoming sources. The air becomes warmer as the day goes on.

Answer: Dog's speed = (20 + 35) /12 = 4.583 m/s

Dog's velocity = (20-35)/12 = -1.25 m/s

Explanation: Speed is a scalar quantity so we don't care about direction which means we add the magnitude of both the directions i.e. east and west.

About the velocity, it's a vector quantity. So, we must be very careful with the directions and signs. In cartesian coordinates system, we generally take the right side of origin as the positive x-axis and the left side of origin as the negative x-axis. So, considering the same fact, we consider east as positive side and west as the negative side.

Therefore, when we add 20m + (-35m), we get = -15m and you already have the time period of  12 s.

Most passenger vehicles are engineered to have a very low center of gravity to ensure stability and reduce the risk of rollovers. This design feature enhances safety while driving and contributes to a more controlled driving experience.

Most passenger vehicles are engineered to have a very low center of gravity. The center of gravity refers to the point at which the weight of the vehicle is evenly distributed. In a vehicle with a low center of gravity, the weight is concentrated closer to the ground, making it more stable and less prone to tipping over.

Having a low center of gravity is important for safety and stability while driving. When a vehicle takes a turn, the centrifugal force tries to push it outward. A high center of gravity would make the vehicle more likely to roll over due to this force. However, a low center of gravity helps keep the vehicle stable by keeping the weight closer to the ground, reducing the chances of rollovers.

To achieve a low center of gravity, car manufacturers design vehicles with certain features. For example, they may place heavy components like the engine and battery lower in the vehicle, lowering the overall center of gravity. They may also design the suspension system to keep the vehicle lower to the ground.

The higher the relative humidity, the lower the vapor pressure gradient between the skin and the environment.

The relative humidity is a measure of the amount of moisture in the air compared to the maximum amount it can hold at a specific temperature. When the relative humidity is high, it means the air is already saturated with moisture, leaving less room for additional evaporation. As a result, the vapor pressure gradient between the skin and the environment decreases. In other words, there is less of a driving force for moisture to evaporate from the skin into the surrounding air. Conversely, when the relative humidity is low, the air has a greater capacity to hold moisture, creating a larger vapor pressure gradient and promoting faster evaporation from the skin.

The Bohr atom The Rutherford–Bohr model of the hydrogen atom. In this view, electron orbits around the nucleus resemble that of planets around the sun in the solar system.

Steam, Heat Exchange, Natural Gas, Throttle The steam is extracted between the high and low pressure turbines at a pressure to be determined, which is then isobarically heat exchanged with the process hot water, exiting the heat exchanger as a saturated liquid. This liquid is then throttled to the condenser pressure and mixed with the fluid exiting the low-pressure turbine.

To calculate the power output of the system, the energy and mass balances for the process must be established. These balances can be used to calculate the mass flow rate of the natural gas, the mass flow rate of the steam, the heat input and the power output. In addition, the properties of the natural gas can be used to calculate the enthalpy of the inlet gas, the enthalpy of the steam, and the enthalpy of the inlet air.

The energy balance equation states that the total energy entering the system is equal to the total energy leaving the system. The mass balance equation states that the total mass entering the system is equal to the total mass leaving the system. From these two equations, the enthalpy of the steam and the mass flow rate of the natural gas can be calculated.

The heat input to the system is equal to the total enthalpy of the steam plus the enthalpy of the natural gas. The power output of the system is equal to the heat input multiplied by the efficiency of the generator. This can be used to calculate the power output of the system.

For the right block to balance the forces and remain steady, it needs to weigh 7.9 kg.

The force is an external agent which is applied to the body or an object to move it or displace it from one position to another position.

When there is no net force acting on the system, the two blocks stay in place. In this instance, the strain in the rope holding the two blocks together balances the pull of gravity on them. The sine of the angles, along with the masses of the blocks, can be used to calculate the tension in the rope.

\(T= (m_1 \times g) \times sin(\theta_1) + (m_2\times g) \times sin(\theta_2)\)

Substituting the known values:

\(T = (10 \times 9.8 )\times sin(23^o) + (m_2\times 9.8 )\times sin(40^o)\)

Solving for m₂:

The constant angular deceleration of the centrifuge is 225 rad/s².

Given data:

Now, we need to find the constant angular deceleration of the centrifuge.

Since the angular deceleration is constant, we can use the formula of angular displacement:θ = ω1t - (1/2)αt²

Where:

Let's calculate the total time taken by the centrifuge to come to rest.Number of revolutions made by the centrifuge after the motor is switched off = N = 50 revolutions.

The time period of one revolution = T = 60 s / 3600 rev. = 1/60 s/rev. The time taken to complete N revolutions = t = N × T = 50 × 1/60 = 5/6 s

Let's plug in the given values in equation (1):0 - 3600(5/6) = (1/2)α(5/6)²

To achieve an average speed of 25 km/h for the entire 18 km distance, you need to drive your car with an average speed of 37 km/h for the additional 13 km.

The total time taken to cover the 18 km distance can be calculated by dividing the total distance by the average speed. The total time is given by:

Total time = Total distance / Average speed

For the first 5 km, you jog at 9.1 km/h, which takes approximately 0.5495 hours. For the additional 13 km, you drive at an unknown average speed, which we'll call V. This takes 13/V hours. The total time is the sum of these two times:

0.5495 + 13/V = 18 / 25

Solving this equation, we find that V ≈ 37 km/h. Therefore, to achieve an average speed of 25 km/h for the entire 18 km, you need to drive your car with an average speed of 37 km/h for the additional 13 km.

The average temperature of the coffee during the first 16 minutes can be determined by finding the average value of the temperature function T(t) = 17 + 80\(e^{-t/47}\) over the interval [0, 16]. The average temperature is approximately 28.33°C.

To find the average temperature of the coffee during the first 16 minutes, we need to calculate the average value of the temperature function T(t) = 17 + 80\(e^{-t/47}\) over the interval [0, 16].

The average value of a function f(x) over an interval [a, b] is given by the integral of f(x) over that interval divided by the length of the interval (b - a):

Average value = (1 / (b - a)) * ∫[a, b] f(x) dx.

Applying this concept to the temperature function T(t) over the interval [0, 16], we have:

Average temperature = (1 / (16 - 0)) * ∫[0, 16] (17 + 80\(e^{-t/47}\)) dt.

Evaluating the integral, we get:

Average temperature = (1 / 16) * [17t - 80 * 47\(e^{-t/47}\)] from 0 to 16.

Plugging in the values, we have:

Average temperature = (1 / 16) * [17 * 16 - 80 * 47\(e^{-16/47}\)) - (17 * 0 - 80 * 47\(e^{-0/47}\))].

If the frequency of wave 'a' is one-third of that of wave 'b', then the time period of wave a will be three times as compared to the time period of wave 'b'

The frequency of a wave is inversely proportional to its time period, and it is defined as the number of oscillations per second.

which means F ∝ 1/T

If we remove the proportionality we will need to add a constant.

which makes the relation F = k/T

Time period is defined as the total time taken by a wave to complete one oscillation.

Now as per the data we have,

let the frequency of wave b be 'F', and the time period of b be 'T'

\(F_{a}\) = F/3 and \(T_{a}\) = T/3

Arranging the data into the formula we get
