The new gravitational attraction will be 1/4 as much

Explanation:

The magnitude of the gravitational force between two objects is given by

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

In this problem, the original force between the two objects is F, when they are separated by a distance r.

Later, the distance between the two objects is doubled, so the new distance is

$r'=2r$

Therefore, the new force will be

$F'=G\frac{m_1 m_2}{(2r)^2}=\frac{1}{4}(\frac{Gm_1 m_2}{r^2})=\frac{F}{4}$

Therefore, the new force will be one-fourth as much.

Answer:

The answer is "Location Y"

Explanation:

Please find the complete question in the attachment.

As we show in the graph when the marble rolling with the full force it will stop on the y location because it is curved, and the marble can't move to another location, that's why the maximum kinetic energy of the marble is at the y location.

Three strategies which local municipality is implementing in addressing the issue

siniylev [52]

Having and drinking hygienic water is human right and is vital to life. The water should be tested, treated and filtered to remove any contaminants that can lead do sickness. Some of the strategies in which local municipality is implementing in addressing the topic of lack of clean water are:
1. Good monitoring of the water supplies
2. Desalination – this is removal of mineral components from saline water especially salt. The procedure is more expensive but is a way to reuse water 
3. Campaign for more proficient and more wisely usage of the water in order to make the people conscious of the fact how important the natural resource water is.

You could heat the syrup, grease the spoon with shortening, because if you do, then the molasses won't stick when you pour it out of the spoon into the batter.

Please help me with this question

Answer: m∠P ≈ 46,42°

because using the law of sines in ΔPQR

=> sin 75°/ 4 = sin P/3

so ur friend is wrong due to confusion between edges

+) we have: sin 75°/4 = sin P/3

=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16

=> m∠P ≈ 46,42°
