An effective early childhood curriculum can be learning how to read and write. Without learning how to read, we wouldn’t be able to communicate through this app, or through online school. We wouldn’t know directions, and we wouldn’t be able to enjoy stories. If we didn’t know how to write, I would not be able to help you figure out the answer to this problem, and your teacher wouldn’t be able to grade anything. Think about it, you ir entire education is based of being able to read and write.
Hope this helps :)
Part a
Just use v=d/t
d = vt
d = 7 x 1.5
For part b
Vf=Vi +at
Vf=0 + (9.8)(1.5)
d= ((Vi + Vf) /2) x t
d = ((0 + Vf) /2) x 1.5
In second equation, use Vf found in first equation
Answer:
in the downward movement of the movement when the constant is lost
Explanation:
When the coin is on the piston it has a relationship given by
a = d²x / dt²
the piston position is
x = A cos wt
a = - A w² cos wt
the maximum acceleration is
a = - A w²
When the piston raises the acceleration of gravity and that of the piston go in the same direction, when the piston descends they relate it is contrary to gravity, therefore when the frequency increases, the point where the acceleration of the piston is greater than gravity arrives and the coin loses contact.
The point where you lose contact is
a = g
g = A w²
In short, in the downward movement of the movement when the constant is lost
Answer:
72% = output / 300j * 100
output = 216 joules
300j - 216j = 84joules remains in the water
