Answer:
0.962 s
Explanation:
Speed = frequency × wavelength
v = fλ
2.60 m/s = f (2.50 m)
f = 1.04 Hz
Period = 1 / frequency
T = 1/f
T = 1 / (1.04 Hz)
T = 0.962 s
Answer:
what is the full question
Explanation:
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:
The speed of Lilac is 0.422 times of the speed of light.
Explanation:
Given that,
Length of the spaceship Lilac at rest, 
When Lilac passes Earth, observers there measure its length to be 688 m, L = 688 m
We need to find the speed of light is Lilac moving with respect to Earth. The formula of length contraction is given by :

So, the speed of Lilac is 0.422 times of the speed of light.
Answer:
The water acts like a lubricant therefore has a smooth motion over the ice.
