You have selected the correct answer and blobbed over it with your pencil.

I assume you must have looked at Saturn's average distance, found 1427,
divided that number by 6, got 237 and change, then looked at the others,
and found that 228 was the only one that's anywhere close.

Answer:

Mars

Explanation:

The distance between Sun and Saturn = 1427 Million km

one sixth of the distance between Sun and Saturn will be

$= \frac{1427\times 10^{6} }{6} km$

= 237.83 Million km

From the given data it is evident that the right answer will be Mars.

As the distance between Mars and Sun is 228 million km which is the closest value to the one sixth of the distance between Sun and Saturn.

How many joules of gravitational potential energy does a person have after they went up stairs that are 10 meters tall? Assume t

Sonja [21]

Answer:

P = 5880 J

Explanation:

Given that,

The mass of a person, m = 60 kg

The height of the stairs, h = 10 m

We need to find the gravitational potential energy of the person. The formula is as follows :

$P=mgh$

Substitute all the values,

$P=60\times 9.8\times 10\\\\P=5880\ J$

So, the required gravitational potential energy is equal to 5880 J.

If he completes the 200 m dash in 23 s and runs at constant speed throughout the race, what is his centripetal acceleration as h

Blababa [14]

Incomplete question.The complete one is here

A runner taking part in the 200m dash must run around the end of a track that has a circular arc with a radius curvature of 30m. The runner starts the race at a constant speed. If she completes the 200m dash in 23s and runs at constant speed throughout the race, what is her centripetal acceleration as she runs the curved portion of the track?

Answer:

$a_c=2.523m/s^2$

Explanation:

Given data

$L_{length}=200m\\r_{radius}=30m\\t_{time}=23s$

Required

Centripetal acceleration

Solution

According to the motions equation the velocity given by:

$V_{velocity}=\frac{L_{length}}{t_{time}}\\V_{velocity}=\frac{200m}{23s}\\V_{velocity}=8.7m/s$

The centripetal acceleration is given by:

$a_{c}=\frac{V_{velocity}^2}{r_{radius}}\\ a_c=\frac{(8.7m/s)^2}{30m}\\ a_c=2.523m/s^2$

The humber bridge in england has the world's longest single span, 1410 m . calculate the change in length of the steel deck of t

Pepsi [2]

Applicable linear expansion equation:
ΔL = αΔTL
In which
ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length

Therefore,
ΔL = 12*10^-6*(18.5-(-3))*1410 = 0.36378 m

A bungee-jumping company operates on a bridge 200 m above the ground. They use bungee cords that are 100 m when they are unstret

zubka84 [21]

Answer:

m = 63.7 kg

Explanation:

As we know that when mass connected to the bungee cord stretch the string then the gravitational potential energy of the person will convert into potential energy of the string at the end

now here we know that when person jump from the top and reach at the end then loss in gravitational potential energy is given as

$U = mgH$

$U = m(9.81)(200)$

$U = 1962 m$

now when it is at the end of the motion stretch in the string will be

$x = 200 - 100 = 100 m$

now potential energy of string is given as

$U_{spring} = \frac{1}{2}kx^2$

$U_{spring} = \frac{1}{2}(25)(100^2)$

now by energy conservation we have

$1962 m = \frac{1}{2}(25)(100^2)$

$m = 63.7 kg$

Answer: The correlation between all of these examples would be They are all earths natural energy balance. To maintain a constant global average temperature, all of the sun’s radiation that enters Earth’s atmosphere must eventually be sent back to space. The greenhouse effect plays a significant role in Earth's energy budget. With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth. However, with the greenhouse effect being enhanced by humans, the energy budget of the Earth is shifted to an imbalance. It is important to understand that a certain amount of energy being retained due to the greenhouse effect is necessary, but too much results in conditions that account for increased global temperatures and climate change.
