It's gotta be C b/c the the graph shows a displacement of 600m at the 5 minutes mark.
I believe the answer is B, as you get closer to a planet moon etc it's gravity starts drawing you closer, so the closer you are to a planet moon etc the stronger it's gravity acts on you
Answer:
Oh I had this question before! :)
Explanation:
Acid - citrus products - the classic one is lemon juice
Anything with a sour taste is acidic
Base - soap, oven cleaner, drain cleaner, baking soda

Answer: The soil will be warmer than the water.
Explanation:
The heat (thermal energy) absorbed can be found using the following equation:
Where:
is the heat
is the mass of the element
is the specific heat capacity of the material.
is the variation in temperature
<u>In the case of soil we have:</u>
(1)
Where:
<u>In the case of water we have:</u>
(2)
Where:
Isolating from both equations:
(3)
(4)
(5)
(6)
Comparing (4) and (6) we can find the soil will be warmer than the water.
Answer:
–625 J
Explanation:
So, we got this formula for the work
W=mgd(Cosθ)
but remember when it's liftin somethin, its work gon be against the work of gravity, so
Cos180°= –1
W=500×1.25×(–1)
W= –625 J
