The pressure exerted by Clive in N/cm² when he stands on one foot, given that one foot is 180 cm² and he has a mass of 72 Kg, is 3.92 N/cm²

We'll begin by obtaining the weight of Clive. This is shown below:

Weight (W) = mass (m) × Acceleration due to gravity (g)

W = mg

W = 72 × 9.8

W = 705.6 N

Finally, we shall determine the pressure exerted. Details below:

Pressure exerted  = Weight of Clive  / Area

Pressure exerted = 705.6 / 180

Pressure exerted = 3.92 N/cm²

Thus, from the calculation made above, we can conclude that the pressure exerted is 3.92 N/cm²

The potential energy of the roller coaster is 176,400 J (joules).

The potential energy of an object is given by the formula PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or vertical position of the object.

In this case, the roller coaster is at a peak of 20m and has a mass of 900kg. The acceleration due to gravity, g, is approximately 9.8 \(m/s^2\).

Using the formula, we can calculate the potential energy:

PE = mgh

= (900 kg)(9.8 \(m/s^2\))(20 m)

= 176,400 J

Therefore, the potential energy of the roller coaster is 176,400 J (joules).

Answer:

The type of lens involved is a convex lens and the object is positioned at the center of the curvature of the convex lens.

According to the question, a real, inverted, and same-sized image of the object is formed.

A concave lens is a diverging lens and always forms virtual images. But convex lenses are converging lenses and are the only type of lens that produce real and inverted images of the corresponding objects.

When an object is placed at the center of the curvature of a convex lens, its corresponding image is formed on the opposite side of the convex lens. The image formed is real and inverted.

The distance of the image from the lens is equal to the distance of the object from the lens.

For a convex lens, the distance of the center of curvature from the lens is double the focal length of the lens.

That's why the convex lens and center of curvature are the correct answer to this question.

Explanation:

The resistance band's elasticity (stretchiness) dictates how easily it can be stretched or can be flexible.

It is the proportion of tensile stress to strain, where strain is the amount of deformation and tensile stress is the tension force applied to a surface area (amount of stretch of the resistance band).

Instead than requiring you to hold additional weight per se, resistance bands function by providing an external resistance force that can be imposed. They are flat, occasionally looping bands that might be thin or thick.

Both rubber bands and springs have a unique quality. The stretch distance affects how hard a band pulls back. The spring constant, denoted by the symbol k (in units of N/m), is a proportionality constant.

It will take the Hubble Telescope 94,247 seconds or 26.18 hours to complete one full rotation around the Earth.

The Hubble Telescope is in a circular orbit around the Earth at a constant speed of 20 m/s. The distance between the telescope and the center of the Earth is:

300 km + 100 m = 300,100 m.

Orbital period T of the Hubble Telescope = T = 2πr / v

where

In this case, r = 300,100 m and v = 20 m/s, so:

T = 2π(300,100 m) / (20 m/s) = 94247 seconds

Thus, it will take the Hubble Telescope approximately 94,247 seconds, or about 26.18 hours, to complete one full rotation around the Earth.

The maximum speed in the simple harmonic motion is given by the following formula:

The expressions of the simple harmonic movement allows to find the maximum speed of the swing is:

The simple harmonic movement is a periodic movement where the restoring force is proportional to the elongation, in the case of a swing it can be approximated to a simple pendulum which is a mass with an inextensible chord., For small oscillations (θ <15º), is described by the expression.

                θ = θ₀ cos (wt + Ф)

                w² = L / g

Where θ are the angles, θ₀ the initial angle, w the angular velocity, t the time and Ф a phase constant that is determined by the initial conditions, g the acceleration of gravity and L the length of the pendulum.

Speed ​​is defined in kinematics.

          w =\(\frac{d \theta}{dt}\\\)

           w = \(- \theta_o w \ \frac{d \theta }{dt}\)  

The speed is maximum when the sine function is equal to ±1

          w =  \(\theta_o w\)  

The angular velocity is related to the period.

          w = \(\frac{2\pi }{T}\)  

Let's replace.

        w = \(\theta_o \ \frac{2 \pi }{T}\)

In rotational motion the eels must be in radians y  and the linear and angular variables are related.

         \(\theta = s/R\\s = R\theta\)

         v = w R

         w = \(\frac{v}{R}\)

We substitute.

        v = \(\frac{2 \pi \ s}{T}\)  

Let's calculate

        v = \(2 \pi \frac{0.290}{2.20}\)2pi 0.290 / 2.20

        v = 0.828 m / s

In conclusion using the expressions of the simple harmonic motion we can find the maximum speed of the swing is:

If A box of mass 210 kg is pulled from rest with a string of tension 1300n inclined at 35° to the horizontal. if the box moved with a speed of 10m/s and the frictional force between the box and surface is 100 n, Then the distance covered by the box is 10.89 meters.

To calculate the distance covered by the box, we need to analyze the forces acting on it and apply the work-energy principle.

Given:

Mass of the box, m = 210 kg

Tension in the string, T = 1300 N

The angle of inclination, θ = 35°

Frictional force, f = 100 N

Initial speed, u = 0 m/s

Final speed, v = 10 m/s

First, let's resolve the tension force into components parallel and perpendicular to the incline. The parallel component of the tension force can be calculated as:

T_parallel = T * cos(θ)

Next, let's calculate the net force acting on the box along the incline. The net force is given by:

Net force = T_parallel - f

Now, using Newton's second law, we can calculate the acceleration (a) of the box:

Net force = m * a

From the given information, we have the final velocity (v), initial velocity (u), and acceleration (a). We can use the following kinematic equation to calculate the distance covered (s):

v^2 = u^2 + 2as

Rearranging the equation, we get:

s = (v^2 - u^2) / (2a)

Now, let's plug in the given values and calculate the distance covered:

T_parallel = 1300 N * cos(35°) ≈ 1067.35 N

Net force = 1067.35 N - 100 N = 967.35 N

a = (967.35 N) / (210 kg) ≈ 4.61 m/s^2

s = (10 m/s)^2 - (0 m/s)^2 / (2 * 4.61 m/s^2) ≈ 10.89 m

Therefore, the distance covered by the box is approximately 10.89 meters.

Chemical energy is a type of energy that is stored in the bonds of a chemical. It is converted into thermal energy when people burn wood or burn gasoline in the engine of a car. Mechanical energy is a type of energy that is stored in objects by tension. Compressed springs and stretched bands are examples of mechanical energy.

Mechanical energy i.e. kinetic energy or potential energy is the energy that is present in an object in motion or the energy that is stored in objects due to their position. Mechanical energy is a type of renewable energy.

The moment of the force about point A found using the moments formula, \(|M| = |F| \cdot \: d \perp\) is 67.695 ft–lb.

The moment of a force is the turning effect of the force about a point.

The moment of the force is given by the formula;

\(|M| = |F| \cdot \: d \perp\)

Where;

d = The perpendicular distance from the point to the line of action of the force.

The length of the sides of ∆ABC are;

AB = √(20.5²+4.38²) ≈ 20.9626907

BC = √(17.2²+7.62²) ≈ 18.812347

AC = √((7.62+4.38)²+(20.5-17.2)²) ≈ 12.4454811

The semi–perimeter of triangle ABC = (20.9626907 + 18.812347 + 12.4454811)/2 ≈ 26.1102594

The area, A, of triangle ∆ABC found using Heron's formula is therefore;

A = √((26.1102594×(26.1102594-20.9626907)×(26.1102594-18.812347)×(26.1102594-12.4454811)) ≈ 115.773

The perpendicular distance, d, from point A to BC is therefore;

d = A/(BC)

Which gives;

d = 115.773/18.812347 ≈ 6.15409696

The magnitude of the moment about point A is therefore;

M = 132 lb × 0.51284138 ft. ≈ 67.695 ft.–lb
