Tides are influenced by the force of gravity exerted by the earth, moon and the sun. The sun has a larger mass than the moon and as such has a greater gravitational pull on the earth. the moon however has greater influence over the tides because they are caused by the difference in gravity fields. This means that the moon is the dominant influence due to the fact that the fractional difference in its force across the earth is greater than that seen from the sun.
Answer:
A. recycling allows resources to be reused, instead of dumped in landfills.
Explanation:
To solve the problem it is necessary to apply the concepts related to Chvorinov's Law, which states that
Where,
= Volume cube
= Superficial Area from Cube
= Volume Rectangle
= Superficial Area from Rectangle
Our values are given as (I will try to develop the problem in English units for ease of calculations),
Applying the Chvorinov equation we have to,
The stipulated time for the cube is 14.5 then,
Answer:
115.6 J
Explanation:
= mass of the block = 3.7 kg
= final speed of the block = 0 ms⁻¹
= initial speed of the block = 7.9 ms⁻¹
= work done on the block
Using work done - change in kinetic energy theorem, we have
I have no clue that’s confusing
