write about any five form of energy with example​

Answer:

During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.

Explanation:

Luck For You!

The process, in which conduction, convection, and radiation drive the water cycle in Earth’s system, is discussed in the answer.

The energy from the sun is what largely drives the water cycle. By evaporating water from the oceans, lakes, rivers, and even the soil, this solar energy powers the cycle. Through the process of transpiration, more water is transferred from plants to the atmosphere. Water droplets gradually acquire enough mass to fall back to Earth as precipitation as liquid water evaporates or transpires, forming clouds and water vapour.

The precipitation eventually transforms into runoff or groundwater and makes its way back into the surface reservoirs across a variety of periods. The hydrosphere currently contains the same amount of water as it has always contained in the Earth system since the water cycle is essentially a closed system.

Solar heat energy comes on earth's surface via radiation to the ponds, lakes, oceans, seas, rivers and other water resources and then the waterbodies get heated via conduction and evaporation happens. During evaporation time temperature water vapor goes to high altitude via convection of heat and cloud forms.

Explanation:

The uniform movement allows to find the average speed, for which the correct answer is:

        B) 1.3 m / s

Kinematics studies the movement of bodies, establishing relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is called uniform motion.

        v = [tex]\frac{\Delta x}{\Delta t}[/tex]

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

In this case

         v = [tex]\frac{2.0 - (-2.0)}{4.0\ -1.0}[/tex]

          v = 1.33 m / s

In conclusion using the uniform motion ratios we can find that the correct answer for the average velocity is

        B) 1.3 m / s

In a distance time graph, when the x and y values are positive (in first quadrant), the runner is moving forward.

While, if the distance value ( in the y axis) is negative, the runner is moving backwards ( towards the start) .

Hope it helps :)

A distance-time graph shows how far an object has travelled in a certain time. This is a simple line graph that plots observations by distance versus time.

 The distance is transferred to the Y axis.

Time is plotted on the X-axis.

The distance-time graph when we study the motion of bodies. If you set the distance and time of the movement of the object and transfer the same data to a rectangular graph, you will get a distance-time graph corresponding to the movement of the object.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  B

Explanation:

From the question we are told that

  The terminal  velocity of both balls is  [tex]v_t  =  32 \ m/s[/tex]

   The speed with which ball A is thrown up at t =0 s is  [tex]v__A}}  =  16\sqrt{2}[/tex]

   The speed with which ball B is thrown 30° below the horizontal  at t =0 s is  

[tex]v__{B}} =  32\sqrt{2}[/tex]

Generally the acceleration of ball A is (g i.e acceleration due gravity)given that it is thrown straight up  

Generally the vertical  acceleration of ball B is mathematically represented as

    [tex]a  = gcos (90 - 30)[/tex]

      [tex]a  = gcos (60)[/tex]

Generally the ratio of both acceleration is  

     [tex]\frac{a__{{A}}}{a__{{B}}}} =\frac{g}{gsin(60)}[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{sin (60)}[/tex]

=>  [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{\frac{\sqrt{3} }{2} }[/tex]

=>[tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} }[/tex]

Rationalizing

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2 \sqrt{3} }{3}[/tex]

=>[tex]a__{B}} = \frac{2\sqrt{3} }{3} * a__{A}}[/tex]

Answer:

one of a set of unrelated units of measurement, which are arbitrarily defined and from which other units are derived. For example, in the SI system the fundamental units are the meter, kilogram, and second.

Explanation:

Answer:

Let's define:

The position zero will be in the first point where the truck and police car meet. (So the initial position of both vehicles is zero)

Then, the position equation for the truck is:

T(t) = 20m/s*t

Where t is our variable, time in seconds.

Now, at t = 5s, the car starts accelerating.

Ac(t) = 2m/s^2                    for( t ≥ 5s)

For the velocity of the car, we must integrate that.

V(t) = (2m/s^2)*(t - 5)           for (t ≥ 5s)

Where i introduced a little change in the variable because the velocity of the car starts to increase for t larger than 5 seconds.

For the position of the car we integrate again.

C(t) = (1m/s)*(t - 5)^2            for (t ≥ 5s)

Now, let's answer the questions:

Determine the time at which the speed of the truck is equal to the speed of the police car.

Then we must have:

V(t) = (2m/s^2)*(t - 5)  = 20m/s.   (Remember that we only can use times requal or larger than 5 seconds).        

2m/s^2*t - 10m/s = 20m/s

2m/s^2*t = 30m/s

t = (30/2) s = 15s

The velocities of both vehicles will be the same after 15 seconds.

t1 = 15s

How the positions will compare at this time?

The easier thing will be to evaluate the position equation of each vehicle in this time:

T(15s) = 20m/s*15s = 300m

C(15s) = (1m/s^2)*(15s - 5s)^2 = (1m/s^2)*(10s)^2 = 100m.

Then we can see that the truck is 200m ahead of the car.

But remember that the police car is accelerating, so the velocity will keep increasing meaning that eventually, the car will catch the truck.
