The value of v; initial velocity is determined as, v = h/t + gt.
<h3>What is initial velocity of an object?</h3>
The initial velocity of an object is the velocity of the object before the effect of acceleration, which causes the change of velocity.
h = vt - gt²
to solve for v (the initial velocity) we will make v the subject of the formula.
h + gt² = vt
divide both sides of the equation by t
h/t + gt = v
Thus, the value of v; initial velocity is determined as, v = h/t + gt.

Answer:
Grams of water can be heated from 20.0°C to 75°C using 12500.0 Joules = 54.3 g
Explanation:
Heat required to increase temperature
H = mcΔT
m = mass of material
C = specific heat of material
ΔT = Change in temperature.
Here we need to find how many grams of water can be heated from 20.0°C to 75°C using 12500.0 Joules
That is
H = 12500 J
Specific heat of water, C = 4186 J/kg°C
ΔT = 75 - 20 = 55
Substituting
12500 = m x 4186 x 55
m = 0.0543 kg
m = 54.3 g
Grams of water can be heated from 20.0°C to 75°C using 12500.0 Joules = 54.3 g
Answer:
When boiling water is poured into a thick tumbler its inner surface expands. However, due to low thermal conductivity of glass, the expansion of outer surface of the tumbler is quite small. Due to uneven expansion of the outer and inner surfaces, the tumbler breaks.
