Calculate the temperature increase ΔT in a 1.40 kg sample of water that results from the conversion of 19% of the gravitational potential energy directly to heat energy in the world's tallest waterfall, the 807-m ‑tall Salto Angel in Canaima National Park, Venezuela.

Answers

Answer 1

According to the given statement As a result, the water's temperature increased by 0.36°C.

What does increase in temperature mean?

Higher temperatures raise the likelihood that heat waves may occur more frequently and last longer. Extreme heat can be deadly, resulting in conditions like heat exhaustion and heat stroke as well as actual mortality. Additionally, increased temperatures have the potential to trigger a variety of additional alterations globally.

Briefing:

The formula below is used to determine the temperature rise (T).

ΔT = 0.19gh/c............. Equation 1

Where:

T stands for temperature rise.

g = Gravitational acceleration

Height is h,

While water's specific heat capacity is c.

From the question,

Given:

h = 807 m

g = 9.8 m/s²

c = 4184 J/kgK

Substitute these values into equation 1

ΔT = (0.19×807×9.8)/4184

ΔT = 0.36°C

As a result, the water's temperature increased by 0.36°C.

What is an electromagnetic wave?

An electromagnetic wave is awave that does not require a medium to propagate

What is an electric field?

An electric field is a region in which the effect of an electric force is felt.

How to find the magnitude of the electric field?

Since a nonsinusoidal electromagnetic wave like that described in section 32.2 has uniform electric and magnetic fields. the magnitude of the poynting vector for this wave is 11.0 W/m².

What is the poynting vector?

The magnitude of the poynting vector is given by

S = E²/μ₀c where

E = electric field, μ₀ = permeability of free space = 4π × 10⁻⁷ H/m and c = speed of electromagnetic waves = 3 × 10⁸ m/s

Since we require the electric field, making E subject of the formula, we have

E = √(Sμ₀c )

Given that S = 11.0 W/m²,

Substituting the value sof the variables into the equation, we have

E = √(Sμ₀c )

E = √(11.0 W/m² × 4π × 10⁻⁷ H/m × 3 × 10⁸ m/s)

E = √(44π × 3 × 10WH/s)

E = √(1320π WH/s)

E = √(4146.9 WH/s)

E = 64.4 V/m

Answers

Cannon A reaches a higher elevation when two cannonballs, a and b, are fired from the ground with identical initial speeds, but with ua larger than ub.

Because elevation rises with increasing angle, Cannon A fires at a higher altitude. Finding the vertical velocity will yield the elevation. The velocity increases as the angle increases. Cannon A's elevation is higher than Cannon B's because the angle from which the projectile was fired from Cannon A was greater. Due to its higher elevation, Cannon A flies higher for a longer period of time. The formula for time is t = (2y)/g, meaning that the larger y is, the larger time will be. Cannon A is in the air for a longer period of time because elevation and vertical velocity affect time.

A closed kinetic chain exercise, according to Steindler, occurs when the distal section encounters "substantial" external resistance that prevents unrestricted movement. As a result, neither the proximal nor the distal portions can move in this system.

Unfortunately, Steindler did not provide a numerical value for the word "substantial" in his original definition, which causes misunderstanding and disagreement over what constitutes a true closed kinetic chain movement. Except during isometric exercises, where there is no movement, true closed kinetic chain movement patterns never happen in the extremities.

However, in clinical practise, "resistance is imposed through the distal portion of the extremity and remains fixed to the extremities" is the definition of a closed kinetic chain. The standing squat is the best illustration of this since the feet stay firmly planted and the surface encounters significant resistance from the athlete's bodyweight or additional weight.

Due to the brass weight's existence, the rod's torque about the pivot is 8.44 N.m.

What is torque?

A force that may rotate an object about an axis is known as a torque. In linear kinematics, force is what drives the acceleration of an object. The same is true for angular acceleration, which is caused by torque. Thus, torque can be seen as the rotating counterpart of force. The term "axis of rotation" refers to the straight line around which the item rotates.

Given parameters:

We have to find, the brass weight's presence causing  torque on the rod about the pivot; ζ = ?

Force applied by the brass weight; F = mass × acceleration due to gravity  = 1.5 × 9.8 N =  14.7 N.

So, the brass weight's presence causing torque on the rod about the pivot; ζ = Fl sinθ
