Yes, you need to use the chain rule. Also you need to use the derivative of arcsin which is in tables.
Derivative of y = arcsin(x) = 1 / [√(1 - x^2)]
Chain rule: Derivative of archsin(cos(2x)) =
y' = 1 / [√(1 - (cos(2x))^2)] * derivative (cos(2x) =
y' = 1 / [√(1 - (cos(2x))^2)] * (- sin (2x)) * 2
y' = -2(sin(2x)) / [√( 1 - (cos(2x))^2]
Hot air always goes for the top of air and its making pressure on piston which makes piston move up.
Answer:
1.38 s
Explanation:
Use the free falling formula
T = √(L)/ g
T = √18.75/9.8
T = 1.38 s
1) the object would change color (start to rust or just chnage color)
2) The new substance is ireversable (cant chnage back to original form)
3)theres gas formations (its can change into a gas property)
