URGENT!! An astronaut on the International Space Station is doing a spacewalk to fix a solar panel that has malfunctioned. While

he is completing his task, a piece of space junk flies past and cuts the line that has him tethered to the space station. He begins to float away and must think quickly in order to get himself back to safety. All the astronaut has with him on his suit are some small tools and a can of compressed air.
What would be the most effective way for the astronaut to get himself back to safety?
A. use a swimming motion to move himself back to the space station
b. toss his tools in the direction of the space station
c. shoot gas from his compressed air canister towards the space station
d. shoot gas from his compressed air canister away from the space station

Answer:

D. Shoot gas from his compressed air canister away from the space station

Explanation:

Isacc Newton's 3rd law states "For every action, there is an equal and opposite reaction." The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Why do you need to evaluate claims made on product labels?
KATRIN_1 [288]

Answer:

Option D, The claims may be biased, is the right answer.

Explanation:

Option D is the correct answer because the primary motive of a company is to earn more profit and it can misguide the consumer by making false and biased claims. Therefore, the evaluation of the claims is the responsibility of the buyers which help them to buy the product beneficial to them. For example, if a product claims that it will glow your skin within seconds then it is the awareness or activeness of the consumer to evaluate such claims which are written on the label and cross verify the ingredients that are used in it because such claims can be false to sell the product.

A)Calculate the effective value of g, the acceleration of gravity, at 7900 m above the Earth's surface.
arsen [322]

The solution for the acceleration of gravity is given as

  • g_{1}=9.789 \mathrm{~m} / \mathrm{s}^{2}$
  • g_2=1.955 \mathrm{~m} / \mathrm{s}^{2}$

This is further explained below.

<h3>What is the effective value of g, the acceleration of gravity, at 7900 km above the Earth's surface.?</h3>

Generally,

Mass of earth $M=5.97 \times 10^{24} \mathrm{~kg}$

Radius of earth $R=6371 \mathrm{~km}$

Gravitational const. $G=6.67 \times 10^{-11} \mathrm{Nm}^{2} \mathrm{~kg}^{-2}$

height $h_{1}=7900 \mathrm{~m}=7.9 \mathrm{~km}$$$

R+h_{1}=6371+7.9 &\\\\R+h_{1}=6378.9 \mathrm{~km} \\\\&R+h_{1}=6378.9 \times 10^{3} \mathrm{~m}\end{aligned}

In conclusion, acceleration due to gravity at this point will be

g_{1}=\frac{G M}{\left(\bar{R}+\overline{h_{1}}\right)^{2}}$\\\\$g_{1}=\frac{6.67 \times 10^{-11} \times 5.97 \times 10^{24}}{\left(6378.9 \times 10^{3}\right)^{2}}$\\\\$g_{1}=9.789 \mathrm{~m} / \mathrm{s}^{2}$

for $h_{2}=7900 \mathrm{~km}$

R+h_{2}=6371+7900\\\\R+h_{2}=14271 \mathrm{~km}\\\\$g_{2}=\frac{6.67 \times 10^{-11} \times 5.97 \times 10^{24}}{\left(14271 \times 10^{3}\right)^{2}}$\\\\$g_2=1.955 \mathrm{~m} / \mathrm{s}^{2}$

The absolute potential at a distance of 2.0 m from a negative point charge is-100. V. What is the absolute potential 4.0 m away
jolli1 [7]

Answer:

The absolute potential 4.0 m away from the same point charge is -50 V.

(A) is correct option.

Explanation:

Given that,

Distance = 2.0 m

Potential = -100 V

Absolute potential = 4.0 m

We need to calculate the charge

Using formula of potential

V=\dfrac{kq}{r}

Where, V = potential

q = charge

r = distance

Put the value into the formula

-100=\dfrac{9\times10^{9}\times q}{2.0}

q=\dfrac{200}{9\times10^{9}}

q=-22.2\times10^{-9}\ C

We need to calculate the potential

Using formula of potential

V=\dfrac{9\times10^{9}\times(-22.2\times10^{-9})}{4.0}

V=-49.95\ V

V=-50\ V

Hence, The absolute potential 4.0 m away from the same point charge is -50 V.
