if you set out to explore the surface of the moon, you would wear a thermally insulated space suit. in such activity, you might expect to generate roughly 4 kj of heat per kilogram of mass per hour. if all this heat were retained by your body, how much would your body temperature increase per hour owing to this rate of heat production? (assume that your heat capacity is roughly that of water) what time limit would you recommend for a moon walk under these conditions?

Answers

Answer 1

Temperature rise hourly = 0.956 degree Celsius

2.3245 hours are the time limit for the process.

How would you define specific heat?

The amount of heat needed to raise a substance's temperature by one degree Celsius in one gram is known as specific heat. Calories or joules per gram per degree Celsius are frequently used as the units of specific heat. For instance, water has a specific heat of 1 calorie (4.186 joules) per gram per degree Celsius.

Heat produced per hour per 1kg = 4 KJ

Heat absorbed per kg per hour = temperature rise x specific heat of body

4 = temp rise x 4.184 KJ/kgK

temperature rise per hour = 4/4.184 = 0.956 C

For calculation of time limit

increase of C = ( increase in F) x 5/9

                        = 4 x 5/9 = 2.22

Now per hour rise = 0.956 C

time required to rise per 2.22 C = ( 2.22 /0.956)

                                                     = 2.3245 hours

Hence time limit = 2.3245 hours

6) A spring with a spring constant k = 800 N/m has been compressed, and 196 J of
potential energy is stored. What distance from equilibrium has the spring been
compressed?

Answers

Answer:

[tex]0.7\; {\rm m}[/tex].

Explanation:

If spring with spring constant [tex]k[/tex] is compressed by [tex]x[/tex] relative to the equilibrium, the elastic potential energy [tex]E[/tex] stored in that spring will be [tex]E = (1/2)\, k\, x^{2}[/tex].

For the spring in this question, it is given that [tex]E = 196\; {\rm J}[/tex] whereas [tex]k = 800\; {\rm N \cdot m^{-1}}[/tex]. The displacement [tex]x[/tex] needs to be found.

Note that [tex]\begin{aligned}E &= 196\; {\rm J} = 196\; {\rm N \cdot m} \end{aligned}[/tex] (one joule is the work done when a force of [tex]1\; {\rm N}[/tex] is applied over a distance of [tex]1\; {\rm m}[/tex].)

Rearrange the equation [tex]E = (1/2)\, k\, x^{2}[/tex] to find displacement [tex]x[/tex] in terms of potential energy [tex]E[/tex] and spring constant [tex]k[/tex]:

[tex]\begin{aligned} x^{2} = \frac{2\, E}{k}\end{aligned}[/tex].

[tex]\begin{aligned} x &= \sqrt{\frac{2\, E}{k}} \\ &= \sqrt{\frac{2 \times 196\; {\rm N \cdot m}}{800\; {\rm N\cdot m^{-1}}}} \\ &= \sqrt{0.49\; {\rm m^{2}}} \\ &= 0.7\; {\rm m} \end{aligned}[/tex].

In other words, the spring has been compressed by [tex]x = 0.7\; {\rm m}[/tex] from the equilibrium.

There are electrons present in the atoms and molecules of objects. A visible light wave will have certain frequency. If the frequency of the light wave matches with the frequency that causes the electron to vibrate, the electrons will absorb the energy of light for vibrational motion. During the vibrational motion, the vibrational energy is converted into thermal energy. This is how light is absorbed.

a ball of mass 0.140 kg moving with speed of 1.72 m/s hits a wall and bounces back with the same speed in the opposite direction. what is the change in the ball's kinetic energy?

Answers

Answer:

[tex]0\; {\rm J}[/tex].

Explanation:

The speed of an object is a scalar quantity and is independent of the direction in which the object is moving.

The kinetic energy of an object depends only on the mass and speed of this object. If an object of mass [tex]m[/tex] is moving at a speed of [tex]v[/tex], the kinetic energy of this object will be [tex](1/2)\, m\, v^{2}[/tex].

As a result, as long as the speed of the object stays unchanged, changes in the direction of motion of the object will not affect the kinetic energy of the object.

In this question, the speed of this ball was initially [tex]1.72\; {\rm m\cdot s^{-1}}[/tex]. The kinetic energy of this object was initially [tex](1/2)\, (0.140\; {\rm kg})\, (1.72\; {\rm m\cdot s^{-1}})^{2} \approx 0.207\; {\rm J}[/tex].

The speed of this ball stays the same after the ball bounces back from the wall: [tex]1.72\; {\rm m\cdot s^{-1}}\![/tex]. As a result, the kinetic energy of this object would still be [tex](1/2)\, (0.140\; {\rm kg})\, (1.72\; {\rm m\cdot s^{-1}})^{2} \approx 0.207\; {\rm J}[/tex].

As a result, the change in the kinetic energy of this object would be [tex]0.207\; {\rm J} - 0.207\; {\rm J} = 0\; {\rm J}[/tex].

What is meant by kinematic equation?

When an object has either a constant velocity or constant acceleration, kinematic equations can be used to help in problem-solving.

A branch of physics called kinematics, which originated in classical mechanics, defines how points, bodies, and systems of bodies move without taking into account the forces that are responsible for their motion.

Generally from the kinematic equation

v = u - g × t/2

So v exists the velocity at maximum height and the value is v = 0 m/s

substitute the values in the above equation, we get

0 = u - 9.8 × 3.7/2

simplifying the above equation, we get

⇒ u = 18.13 m/s

Here u exists the initial velocity of the dart as it leaves that gun.

Generally the horizontal range of the dart is mathematically represented as

[tex]$R=\frac{u^2 \sin 2 \theta}{g}$$[/tex]

For maximum horizontal range the value of θ = 45°.

So, R max = [tex]$\frac{18.13^2 \sin 2(45)}{9.8} \\[/tex]

assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32°f. suddenly, the wind speed increases and remains gusty throughout the night. the minimum temperature will most likely be .

Answers

Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32°f. suddenly, the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be higher than predicted due to mixing.

As wind speed increases, it moves the air molecules at a greater frequency due to collisions, and hence, the overall kinetic energy of the molecules increases making them move at a higher speed.

When the night is calm and clear then the surface of earth will be cooler than usual as the air molecules move at normal speed. However, when the wind speed increases, it draws warmer air from the surrounding which is mixed downward on the earth's surface preventing the temperature from dropping. Therefore, on a such night, the temperature will be slightly warmer than usual.

What is the principle of moments?

The principle of moments is the principle that describes the turning effect produced by forces.

The principle of moments states that for a system of balanced forces, the sum of the clockwise moment about a point equals the sum of the anticlockwise moment about the same point.

The formula for calculating moments about a poit is given below:

Moment = force x perpendicular distance from the fulcrum

Considering the given questions:

1. Assuming the fulcrum is the balance point of the plank balance.

Taking left as anticlockwise and right as clockwise motion

Anticlockwise moment = 30 * 3

Anticlockwise moment = 90

Clockwise moment = 45 * 2

Anticlockwise moment = 90

Therefore, the plank balance is balanced.

2. Assuming the fulcrum is the balance point of the plank balance.

Taking left as anticlockwise and right as clockwise motion

Clockwise moment = 500 * 50

Anticlockwise moment = 25000

Anticlockwise moment = 200 * d

Anticlockwise moment = 200d

200d = 25000

d = 125 cm to the left of the fulcrum

3. Assuming the fulcrum is the balance point of the plank balance.

Taking left as anticlockwise and right as clockwise motion

Clockwise moment = 10 * 4

Answers

The boot and incline have 0.859 as their static and kinetic friction coefficients.

How to simplify the equations of kinetic and mechanical energy?

We start for the first angle where the given angle is 36.5 ° and the acceleration is zero.

The force equations would be given by:

F = m g sin θ

N = m g cos θ

Fr = μs N

Where μ is coefficient of friction (static)

If we make a sum of forces in the direction in which the block moves we will have the sin θ Component and that of the friction force, so

∑ F = 0

F - Fr = 0

F = Fr

mg sin θ = μ N

m g sin θ = μ m g cos θ

solving for the coefficient, then

μ = sin θ / cos θ = tan θ

substitute the value in the above equation, we get

μ = tan (36.5)

μ = 0.740

We apply the same consideration for the angle of 30.5°, then we know that

μk = tan θ

substitute the value of θ, in the above equation, we get

μk = tan (30.5)

μk = 0.859

In 1–2 sentences, explain how you would determine the constant k for a spring.

PLS help! ASAP

Answers

To determine the force constant (k) of a spring, we need to perform an experiment which requires a retort stand and clamp, a spiral spring, a meter rule and different weights.

Force constant of the spring or the spring constant can be defined as the stiffness of the spring.

Also it is the defined as the force require to cause displacement.

The setup is arranged as shown in the image attached as Fg.1.

The natural length of the spring is first recorded. Different weights are added to the spring one after the other and the extension is recorded, each time when the different weights are added simultaneously

The weight is now plotted on the vertical axis and the extension is plotted on the horizontal axis. The slope of the graph is the force constant of the spring.

The graph is shown in the image attached as Fig.2

Vertical part of The F Sign theater will be equal to F. Our result is 76.4 degrees. I apologize, 76.4 Newton. This completes the vertical element of the solution.

In this issue, a luggage handle is pushed while inclined 46 degrees from vertical. 110 Newtons of force, parallel to the handle, are applied. Additionally, we must determine the magnitudes of the horizontal and vertical components of the applied force. so make a vertical angle. 46 degree force is additional.

As a result, the angle with the horizontal will be equal to 44 3 degrees, or roughly 93 - 46 degrees. Therefore, the title to 40 40 is the angle with the positive x-axis of the force. Therefore, fx's horizontal component is F.

Cost information 110 Newton times 44 degrees of force. This results in F. X. about 79.1 Newtons. We must determine the vertical component in section B. Because of this, the vertical component F. I will equal the F Sign theater. Our result is 76.4 degrees. I apologize, 76.4 Newton. This completes the vertical element of the solution.
