Heat is transferred when a substance changes phases. Substances can be made to change phases by fluctuating the temperature, the pressure, or both. I hope I could help!
im pretty sure this is right 4. true 5. force
Answer:
Vf = 41.6 [m/s]
Explanation:
To solve this problem we must use the equations of kinematics.
Vf² = Vo² + (2*g*y)
where:
Vf = final velocity [m/s]
Vo = initial velocity = 0
g = gravity acceleration = 9.81 [m/s²]
y = height = 88.2 [m]
Note: The positive sign of the equation tells us that the acceleration of gravity goes in the direction of motion.
Vf² = Vo² + (2*g*y)
Vf² = 0 + (2*9.81*88.2)
Vf = (1730.48)^0.5
Vf = 41.6 [m/s]
False because they can be really big
sorry for the explanation on how bad it was LOL
Answer:
engineering teaches you how to think creatively and be able to strategize in real life situations.
