The answer Is B! Good luck
Answer:
it bc the adults are bigger then us kid so when they dip in the pool it makes bigger splashes
Explanation:
When water changes into vapor, it is called evaporation. BONUS: This is formed by the boiling point of water, which is 230°F (Fahrenheit) or 110°C (Celsius).
Answer:
A.C. Generator
Explanation:
The device designed to convert chemical energy into kinetic energy is an A.C generator.
The generator uses fuel to cause the mechanical motion of the pistons in the device.
- Chemical energy is a form of energy found between the bonds of compounds and molecules.
- When the bonds are broken, energy is released.
- The heat energy produced drives pistons and cause mechanical motion of the body.
- This is a form of kinetic energy which causes the motion of a body.
Answer:
y₁ = 37.2 m, y₂ = 22,6 m
Explanation:
For this exercise we can use the kinematic equations
For the globe, with index 1
y₁ = y₀ + v₁ t
For the shot with index 2
y₂ = 0 + v₂ t - ½ g t²
At the point where the position of the two bodies meet is the same
y₁ = y₂
y₀ + v₁ t = v₂ t - ½ g t²
14 + 8.40t = 27.0 t - ½ 9.8 t²
4.9 t² - 18.6 t + 14 = 0
t² - 3,796 t + 2,857 = 0
Let's look for time by solving the second degree equation
t = [3,796 ±√(3,796 2 - 4 2,857)] / 2
t = [3,796 ± 1,727] / 2
t₁ = 2.7615 s
t₂ = 1.03 s
Now we can calculate the distance for each time
y₁ = v₂ t₁ - ½ g t₁²
y₁ = 27 2.7615 - ½ 9.8 2.7615²
y₁ = 37.2 m
y₂ = v₂ t₂ - ½ g t₂²
y₂ = 27 1.03 - ½ 9.8 1.03²
y₂ = 22,612 m
