Earth has a radius R = 1.5 x 1011 m, T= 365.3 days, and m= 5.97 x 1024 kg. Calculate the
speed of Earth around the sun, assuming a circular orbit.

Answers

Answer 1

Answer:

[tex]29861.23\ \text{m/s}[/tex]

Explanation:

[tex]R=\text{Radius of Earth's orbit}=1.5\times10^{11}\ \text{m}[/tex]

[tex]T=\text{Time taken by the Earth to complete the orbit}=365.3\ \text{days}[/tex]

Assuming the orbit is of circular shape the distance the Earth has to travel is the circumference

[tex]C=2\pi R\\\Rightarrow C=2\pi\times 1.5\times10^{11}\\\Rightarrow C=942477796076.938\ \text{m}[/tex]

Velocity is given by

[tex]v=\dfrac{C}{T}\\\Rightarrow v=\dfrac{942477796076.938}{365.3\times 24\times 60\times 60}\\\Rightarrow v=29861.23\ \text{m/s}[/tex]

The speed of the Earth around the Sun is [tex]29861.23\ \text{m/s}[/tex]

if 270 watts of power is used in 42 seconds, how much work was done

Answers

Answer: W = 11340J

Explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

So this is the Formula: Power = Work / Time.

Step 1: Find the Formula

P = W / T

Step 2: Make W the subject of the equation.

W = PT

Step 3: Given.

P = 270 Watts, T = 42 seconds

Step 4: Substitute these values into equation 2 .

W = 270(42)

Step 5: Simplify.

W = 11340J

The amount of work done was 11340.

To celebrate a victory, a pitcher throws her glove straight up into the air with an initial velocity of 6.0 m/s. What is the maximum height of the glove? (Show work)

Answers

Answer:

h = 1.8 m

Explanation:

The initial velocity of the glove, u =- 6 m/s

We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0

[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g

[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]

Hence, it will go up to a height of 1.8 m.

When you cook a marshmallow on a metal poker tool over an open flame, energy is transferred. Identify the three different ways thermal energy is transferred in this situation. Be sure to name the specific places or phenomenon in this system where each of the types of thermal energy transfer is occurring and the direction the energy is being transferred (from what to what).

Answers

Answer:

The three ways thermal energy is transferred are;

1) Conduction

2) Convection

3) Radiation

Explanation:

1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow

2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame

3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.

A student weighs 530 N. The walk to the top of a 3m staircase. It takes them 5 seconds. How

Answers

Answer:

W = 1590 J

Explanation:

We could use the formula of potential energy to find work as both have the same units,

                    W = mgh

since weight = mg so,

                     Work = weight x height

                               = 530 x 3

                               = 1590 J

Answer:

The work will be 1590 J

since the formula is W = F x D so I cancel the time

Explanation:

Given:

(Force) F = 530N

(Distance)D = 3m

Unknown:

W or Work

Formula and Solution:

W = F x D

W = (530N) (3m)

Final Answer:

W = 1 590 N·m or simplify as 1590 J

it takes 275n to set a stationary 77.3 crate in motion. what is the coefficient of static friction?

Answers

Note: I'm assuming the data 77.3 is the mass of the crate.

Answer:

[tex]\mu_s =0.36[/tex]

Explanation:

The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).

[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]

The normal force is numerical equivalent to the weight of the body if no other external forces are acting.

[tex]N=m\cdot g[/tex]

The mass of the crate is m=77.3 Kg, thus its weight and normal force is:

[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]

[tex]N= 757.54\ Nw[/tex]

Now we calculate the coefficient:

[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]

[tex]\boxed{\mu_s =0.36}[/tex]

Spring A has a spring constant of 5 N/m and spring B has a force constant of 9 N/m. A weight of 2 kg is applied to spring A and a weight of 10 kg is applied to spring B. Which of the following is true for the final displacements of springs A and B?
a) Spring B has a larger displacement than spring A. b) Spring A has a larger displacement than spring B. c) Spring A and spring B have the same displacement.

Answers

Answer: Option A.

Spring B has a larger displacement that spring A.

Explanation:

Spring B has a larger displacement that spring A .

By using Hooke's law.

F=-Kx

Where F is force, K is spring constant and x is displacement.

For spring a

Weight / force is 2 kg

Spring constant (K) is 5/nm

Therefore,

F=-Kx

2=-5x

X=2/-5

X= -0.4m

For spring B.

Weight is 10Kg

Spring constant is 9N/m

F=-Kx

10=-9x

X=-10/9

=-1.1m

Therefore Spring B have larger displacement than spring A.

In Hooke's law, negative sign that is present on the spring's force indicate that the force exerted by the spring opposes the spring's displacement.

A car traveling initially at the speed of 30 m/s slows down at the rate of -2m/s^2 for a distance of 60 meters. What is the car’s velocity after covering this distance?

Answers

Answer:

Vf = 25.7 [m/s]

Explanation:

To solve this problem we must use the following kinematics equation:

[tex]v_{f} ^{2}= v_{i} ^{2}-(2*a*x)[/tex]

where:

Vf = final velocity [m/s]

Vi = initial velocity = 30 [m/s]

a = desacceleration = 2 [m/s^2]

x = distance = 60 [m]

Note: the negative sign in the equation means that the car slows down.

Now replacing:

[tex]v_{f}^{2}=(30)^{2}-(2*2*60)\\ v_{f}^{2} = 660\\v_{f} =\sqrt{660} \\v_{f}=25.7[m/s][/tex]

How long does it take a dropped object to fall 45 meters?

Explanation:

In the paragraph, Jefferson states defending the rights of states is one of the fundamental, or most significant, policies of our administration. Did that get you to remember the Tenth Amendment?

Unlisted authorities belong to the states.

The conflict has already claimed more than 500,000 lives and displaced huge numbers of people. Among these were at least 20,000 children, mostly boys, between 7 and 17 years of age who were separated from their families. These lost boys of the Sudan trekked enormous distances over a vast unforgiving wilderness, seeking refuge from the fighting. Hungry, frightened and weakened by sleeplessness and disease, they crossed from the Sudan into Ethiopia and back, with many dying along the way. The survivors are now in camps in Kenya, the Sudan and UgandaQuestion 1: What's the main idea,detail 1 and detail 2?TEXT 2:This extraordinary exodus has its origins in traditional forms of migration. After being initiated into manhood, young adolescent boys in southern Sudan have generally been quite mobile. Organized into small groups of their peers, they would leave home for a period to look after cattle.

In addition, at times of stress families all over Africa send their children elsewhere to find safety, food, work and schooling.Question 2: What's the main idea,detail 1 and detail 2?TEXT 3:But during the war this process has escalated dramatically.
