Answer: Option D: 5.5×10²Joules

Explanation:

Work done is the product of applied force and displacement of the object in the direction of force.

W = F.s = F s cosθ

It is given that the force applied is, F = 55 N

The displacement in the direction of force, s = 10 m

The angle between force and displacement, θ = 0°

Thus, work done on the object:

W = 55 N × 10 m × cos 0° = 550 J = 5.5 × 10² J

Hence, the correct option is D.

So, the initial altitude of the parachuter is approximately <u>(C). 123 m</u>.

<h2>Introduction</h2>

Hi ! In this question, I will help you. In this question, you will learn about the fall time of the free fall motion. Free fall is a downward vertical motion without being preceded by an initial velocity. When moving in free fall, the following equations apply:

<h3>The equation for calculating the height (h)</h3>

\boxed{\sf{\bold{h = \frac{1}{2} \cdot g \cdot t^2}}}

<h3>The equation for calculating the time (s)</h3>

\boxed{\sf{\bold{t = \sqrt{\frac{2 \cdot h}{g}}}}}

<h3>The equation for calculating the velocity (v)</h3>

\boxed{\sf{\bold{v = \sqrt{2 \times g \times h}}}}

With the following condition :

  • t = interval of the time (s)
  • h = height or any other displacement at vertical line (m)
  • g = acceleration of the gravity (m/s²)
  • v = velocity (m/s)

<h2>Problem Solving</h2>

We know that :

  • t = interval of the time = 5 s
  • g = acceleration of the gravity = 9.81 m/s²

What was asked :

  • h = height or displacement at vertical line = ... m

Step by Step :

\sf{h = \frac{1}{2} \cdot g \cdot t^2}

\sf{h = \frac{1}{2} \cdot 9.81 \cdot 5^2}

\sf{h = \frac{245.25}{2}}

\boxed{\sf{h = 122.625 \: m \approx 123 \: m}}

<h3>Conclusion</h3>

So, the initial altitude of the parachuter is approximately 123 m (C.)

When is your weight is equal to mg?<br>​
Vinil7 [7]

Answer:

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.

Carbonation, Hydrolysis and Oxidation all relates to chemical reactions with the rocks - so these are forms of Chemical weathering

Frost wedging is where the rocks and earth is broken apart by water freezing and turning to ice. It has nothing to do with rocks themselves changing in their chemical composition. So this is a type of physical weathering.

------------------------------------------------------

Answer:

<u>Frost wedging</u> is a type of physical weathering.
