Answer:
f = pl / (l + p)
Explanation:
1/f = 1/p + 1/l
Find the common denominator of the right hand side.
1/f = l/(pl) + p/(pl)
Add:
1/f = (l + p) / (pl)
Take the inverse of both sides:
f = pl / (l + p)
Answer:d
Explanation: oil would form droplets but only tiny ones because it’s surface tension is lower than that of water
<span>V² = 2*a*y = 1.17 m²/s² at 0.45 mm height
H = V²/(2g) + 0.00045 = 0.0597 + 0.00045 = 0.06014 m = 6.014 cm </span>
Answer:
F = 10 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = forces [N]
m = mass = 0.05 [kg]
a = acceleration = 200 [m/s²]
Answer: Because of the amount of energy
Explanation: Heat is an energy, and small amounts of it does not effect large areas, whereas a very large blast of heat energy can greatly effect the air
