Yes it does.
On the periodic table, tin is #50 and Mercury is # 80.
Answer:
2 m/s²
Explanation:
the equations of motion are
S= ut +½at²
v² = u²+ 2as
v = u + at
s = (u+v)/2 × t
From the parameters given
u = 0m/s this is because it starts from rest
Distance (s) = 9m
Time (t) = 3s
Based on this the first equation would be used
s = ut + ½at²
Input values
9 = 0×3 + ½ × a x 3²
9 = 0 + 9a/2
9 = 4.5a
Divide both sides by 4.5
a = 9 / 4.5 m/s²
a = 2 m/s²

The following choice that is NOT a way that machines provides a mechanical advantage is to change direction. The correct answer is A.
The increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
5000 = 225 × 0.385 × ∆T
5000 = 86.63∆T
∆T = 5000/86.63
∆T = 57.72°C
Therefore, the increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.
