The statement ' The hemisphere tilted towards the Sun experiences summer and the hemisphere tilted away from the Sun experiences winter.' is true.

The variation in seasons is due to the slight tilt of the earth on its axis towards the sun. This tilt is approximately equal to 29 and 1/2 degrees.

Due to this tilt of the earth, the north pole or the south pole of the northern or the southern hemisphere respectively never directly faces the sun.

But when the respective hemisphere is tilted towards the sun, it is as close to the sun as it is physically possible, and therefore that hemisphere experiences the summer season.

Whereas the other hemisphere which is tilted away from the sun is as far from it as possible and receives very little sunlight and hence experiences the winter season.

In the context of the above discussion, the statement ' The hemisphere tilted towards the Sun experiences summer and the hemisphere tilted away from the Sun experiences winter.' is true.

V(rc) = 50 km/h x sin(60)

V(rc) = 43.3 km/h

Velocity of the rain with respect to the earth

V(re) = speed of the car =  50 km/h

All animals with cloven hooves, including cattle, sheep, goats, came lids, deer, and pigs, are susceptible to the deadly and contagious foot-and-mouth disease (FMD). Animals with divided hooves are known as cloven-hoofed animals. Zebras and horses are unaffected.

Humans, not animals, are affected by the hand, foot, and mouth disease (HFMD), which is common in young children. FMD is a different illness. People cannot contract FMD by eating infected beef.

(A) Your walking time during the journey is 180 seconds.

(B) Your average speed during the journey is 2.8 m/s.

The time of motion is the time taken for an object to travel a given distance.

V(average) = displacement / time of motion

time of motion = displacement / average velocity

time of motion = (360 m) / (2 m/s)

time of motion = 180 seconds

Since Joe is running towards the goal line and slowing down, the option that describes this motion is negative velocity, negative acceleration.

A negative velocity occurs when an object moves in the negative direction.

Example of negative velocity;

If a car is moving away from you (reference point) then the velocity is positive.

If a car is coming towards you (reference point) then the same vector reverses direction and hence the velocity is negative.

If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion. Thus, the acceleration of the object will be negative.

The magnitude and direction of the object's displacement is 7 m and west direction respectively.

The displacement of an object is the change in the position of the object. Displacement is a vector quantity because it has both magnitude and direction.

To find the sum of the vectors, we find the displacement of the vectors.

Initial position of the vector = 10 m east

final position of the vector = 3 m west

displacement of the vector = final position - initial position

displacement of the vector = 3 m - 10 m

displacement of the vector = - 7 m

magnitude of the displacement = 7 m

direction of the displacement = west

(a) The distance traveled by the driver before stopping is 20.57 m.

(b) When you have traveled only half the distance in part (a), your speed is greater than 6.0 m/s.

(c) The speed of your car when you have traveled half the distance in part (a) is 8.49 m/s.

The distance traveled by the driver before stopping is calculated as follows;

v² = u² + 2as

when the car stops, the final velocity, v = 0

0 = u² + 2as

0 = 12² + 2(-3.5)s

0 = 144 - 7s

7s = 144

s = 144/7

s = 20.57 m

v² = (12²) - 2(3.5)(0.5 x 20.57)

v² = 72.005

v = √72.005

The 15 km/s velocity is equivalent to 15000 m/s and 54000 km/h.

Velocity is a vector quantity. It consist both a direction and a magnitude. The magnitude of velocity is called speed. Its S.I. unit is a meter/second. It also has other units like Km/h and Km/s. Its dimensional formula is [[tex]LT^{-1}[/tex]].

Given in the question

Velocity is 15 Km over a second

We can infer from the given value that the body moves 15 km per second.

1 Km = 1000 m

1 Km × 15  = 15 × 1000 m

So 15 Km = 15000 m

Hence we can say that the body travels 15000 meters in a second.

As a result, its velocity in m/s is 15000 m/s.

Now

15 kilometers can be covered in 1 second.

Distance traveled in 3600 seconds = 3600 × 15 Km

So the total distance traveled in 3600 seconds is 54000 kilometers.

Also 3600 seconds = 1 hour

In other words, The body travels 54000km in 1 hour, hence its velocity is 54000 km/h.

The velocity of a projectile is the rate of change of displacement of the projectile.

The velocity of a projectile can be vertical or horizontal.

The vertical velocity of a projectile is affected by force of gravity. When an object is thrown upwards, the speed of the object decreases because the force of gravity acts in opposite direction to the motion of the object.

The speed of the object decreases and eventually becomes zero when the object reaches maximum height.

As the object begins to descend, its velocity increases because the object is moving in the same direction as the force of gravity, and the velocity of the object eventually becomes maximum before the object hits the ground.

Repeated trials are when a measurement is performed more than once at least three times, most often five but the more the better.

The likelihood that a measurement made once will yield an accurate result is substantially smaller. However, if you measure it multiple times, you may average the results to produce a value that is considerably more accurate.

In repeated trials, the same thing is measured repeatedly to increase the accuracy of your results. This is essential since data in the actual world frequently varies and nothing is flawless. Your average will get more closely to the genuine value as you perform more trials.

The maximum distance covered by the car from point A to B will be 120 meters, and the minimum distance covered by the car will be 25 meters.

Measuring is the most important scientific concept. Many different types of quantifiable quantities can be measured using base or physical fundamental units. One such quantifiable quantity is speed, which computes the proportion of a moving object's distance travelled to its travel time.

According to the question,

Point A and B are taken on X-axis and point B,C and D are taken on y-axis.

On going from point A to B,

Time taken= 10 seconds

Speed= 12 m/s

Distance covered will be : Speed × time

=12 × 10 sec

Distance= 120 meters

On going from Point B to C,

Time taken= 5 Seconds

Speed= 5 m/s

Distance covered by car will be : Speed × Time

=5 × 5 sec

Distance= 25 meters.

Now, On going from point C to D,

Time taken= 15 seconds

Speed= 2 m/s

Distance covered = speed × time

= 2 × 15 sec

Distance= 30 meters

The generally accepted boundary where space begins, which is also the point where the atmospheric pressure is assumed to be zero, is called the Kalman line. Simply put, gases move from areas of high pressure to areas of low pressure. And the greater the pressure difference, the faster air moves from high pressure to low pressure. This draft is the wind we experience.

As the air rises the surface pressure decreases. As the air rises, it expands and cools adiabatic cooling that is, it cools by changing volume rather than by increasing or decreasing heat.
