What force causes centripetal acceleration of a car making a turn on a flat road?

The correct answer is the most likly factor that contribute to this difference is angle of solar radiation and temprature.

Seasonal temperatures of sites at various latitudes are influenced by the angle of incoming solar radiation. The incoming solar energy is more direct (almost perpendicular or closer to a 90° angle) when the sun's rays hit the surface of the Earth close to the equator. Warmer temperatures result from the solar radiation being concentrated over a smaller surface area. Higher latitudes have narrower solar radiation angles, which spread energy across a broader region of the surface and result in cooler temperatures. Surface temperatures are typically warmer at lower latitudes and cooler at higher latitudes because the angle of radiation varies with latitude (even though higher latitudes have more hours of daylight during the summer months).

The power that the brakes/friction produce to bring the car to rest in 3 seconds is 86,666.667 W

This is how it is works:

Mass = 1300 kg

Speed = 20 m/s

Time = 3 seconds

Power to stop the car = ?

We can use the formula of kinetic energy to solve this problem. Let's take a look:

K.E = ½ m × v²

K.E = ½ 1300 × 20²

K.E = 650 × 400

K.E = 260,000 J

We got the kinetic energy that valued 260,000 J but we do not finished yet. In the question, we should stop the car in 3 seconds then we should find the power produced by the brakes. Here it is:

Power = Work : Time

Power = 260,000 : 3

Power =  86,666.667 W

Kinetic energy refers to the energy of a body due to its motion. The kinetic energy can be calculated as follows:

Answer:

The velocity of the bird is 2 m /sec.

Explanation:

The formula for kinetic energy is given.

Where m is mass, and v is the velocity.

As given

A 4.0 kg bird has 8.0 joules of kinetic energy.

m = 4.0 kg

K.E =  8.0 joules

Putting in the formula

Thus

v = 2 m/sec

Therefore the velocity of the bird is 2 m /sec.

The speed of the aircraft relative to the ground is 606.9 km/h.

Solution:

x-y coordinate system:

x is positive east. Similarly, y is positive north.

Now let's decompose each vector into x-y

500 km/h due east = (500, 0)

120 km/h at 30 north of east

= (120cos(30), 120 x sin(30)

= (120 x [tex]\frac{\sqrt{3} }{2} , 120*\frac{1}{2}[/tex])

= (60 x [tex]\sqrt{3}[/tex], (60)

Adding the vectors.

= (500,0)+(60 x [tex]\sqrt{(3)}[/tex],(60)

= (500 + 60 x [tex]\sqrt{(3)}[/tex],60

= (500 + 60 x 1.73,60)

= (500 + 103.8,60)

= (603.8,60)

Returning back to polar form

Magnitude = [tex]\sqrt{603.923^{2}+60^{2} } = 606.9[/tex]

The speed of the aircraft relative to the ground is equal to the speed of the aircraft relative to the air plus the velocity of the air relative to the ground.

Acceleration refers to any process where velocity changes. There are only two ways to accelerate: either by speeding up your acceleration or by reversing your acceleration. Because velocity consists of both a speed and a direction, this is the case.

You cannot possibly be accelerating if you don't also change your direction and speed, regardless of how quickly you are moving. As a result, a jet does not experience acceleration even when moving at a high speed—in this case, 800 miles per hour—because its velocity is constant.

The calculated efficiency of heat engine during each cycle is 25%.

A heat engine is a machine that transforms heat energy into usable mechanical work for people. The process is carried out using a straightforward apparatus. The ratio of the work a heat engine performs to the heat it absorbs throughout each cycle is referred to as the heat engine's efficiency. It can also be referred to as the heat engine's thermal efficiency. If there is the greatest difference between the hot and cold reservoirs, a heat engine can operate at its maximum efficiency. There is no unit for efficiency.

A formula and a symbol can be used to indicate the efficiency of the heat engine, which is a fraction of the heat and useful work produced. The formula for heat engine efficiency is,

where,

η= Thermal efficiency, W= Acquired useful work, Q1= Given heat energy

The energy given to the heat engine= 400 Joule

And the energy exhausted by the heat engine= 300 Joule

So, during each cycle of operation, the engine's efficiency can be calculated by:

η= [tex]\frac{Q1-Q2}{Q1}[/tex]

η= [tex]\frac{400-300}{400}[/tex]
