Answer:
T = 4 sec / 2 = 2 sec period of revolution
S = 2 pi R = 2 * pi * 1.75 m = 11 m
V = S / T = 11 m / 2 sec = 5.5 m/s speed of object
We have,
- Mass of both students is 60 kg
- Surface area of heels of one student say A is 0.45 cm² = 0.45/10000 m²
- Surface area of heals of another student say B is 74 cm² = 74/10000 m²
And we know that,
Here, area is provided but the force applied will be due to the acceleration of gravity so,
- F = ma
- F = 60 × 9.8
- F = 588
Now, let us calculate the pressure applied by both students;
Pressure(Student A)
- P = 588/0.45 × 10000
- P = 58800 × 10000/45
- P = 1306.6 × 10000
- P = 1306000.0 pascal
Pressure(Student B)
- P = 588/74 × 10000
- P = 5880000/74
- P = 7837.83
From the above two solutions we can say that, Pressure(Student A) > Pressure(student B)
And thus we can also say that,

<h2>
Distance traveled in 1 second after drop is 4.9 m</h2><h2>
Distance traveled in 4 seconds after drop is 78.4 m</h2>
Explanation:
We have s = ut + 0.5at²
For a free falling object initial velocity u = 0 m/s and acceleration due to gravity, g = 9.8 m/s²
Substituting
s = 0 x t + 0.5 x 9.8 x t²
s = 4.9t²
We need to find distance traveled in 1 s and 4 s
Distance traveled in 1 second
s = 4.9 x 1² = 4.9 m
Distance traveled in 4 seconds
s = 4.9 x 4² = 78.4 m
Distance traveled in 1 second after drop = 4.9 m
Distance traveled in 4 seconds after drop = 78.4 m
Explanation:
water? if that what the question means
A comet speeds up as it approaches the Sun. Which statement about its kinetic energy is correct option is - (1) The comet has no kinetic energy because it is in outer space.
- Large ice and dust-based bodies known as comets circle the Sun. These ancient objects, which are best known for their long, streaming tails, are relics from the solar system's birth 4.6 billion years ago. The majority of comets are located outside of our solar system. Some are found in the Kuiper Belt, a vast disc that extends past Neptune's orbit. These are known as short-period comets. They orbit the Sun in lesser than 200 years.
- The Outermost Layer, the solar system's sphere-shaped outer edge, which is nearly 50 times further from the Sun than the Kuiper Belt, is home to additional comets. Because of how much longer it takes them to orbit the Sun, these are known as long-period comets. The comet with the longest known orbit completes one orbit in excess of 250,000 years.
