Answer:
Two scientists in a lab examining vials of urine they are analyzing for levels of excreted protein.
Explanation:
i think its b cause if you were talking about ice it freezes the melts the evaporates to gas
<span>Our equation 1 would be
m*v=M*V1+m*V2
v=V1+V2
v-V1=V2
the equation 2 would look like this
</span>V^2=V1^2+V2^2
V^2-V1^2=V2^2
(V-V1)*(V+V1)=V2^2Dividing with the 1
V+V1=V2
The velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.
<h3>
Velocity of the boy at the bottom of the slide</h3>
The velocity of the boy when he hits the water at the bottom of the slide is calculated from the principle of conservation of energy.
K.E = P.E
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of the boy
- g is acceleration due to gravity
v = √(2 x 9.8 x 10)
v = 14 m/s.
Thus, the velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.

Answer:
-88 °C
Explanation:
Charles' law is derived from the ideal gas law. The ideal gas law says:
PV = nRT
If n and P are constant, then we get Charles' law:
V₁ / T₁ = V₂ / T₂
Plugging in values and solving:
(125 L) / (35 + 273 K) = (75 L) / T
T = 185 K
T = -88 °C
