Answer:
The mass of the fish is 18.1 kg.
Explanation:
Given;
weight of the fish, F = 108 N
extension of the spring by the given weight, x = 14 cm = 0.14 m
First, determine the elastic constant of the spring by applying Hook's law;
F = kx
where;
k is the spring constant
k = F/x
k = 108 / 0.14
k = 771.43 N/m
When the spring is stretched to 23cm, the mass of the fish is calculated as follows;
Therefore, the mass of the fish is 18.1 kg.
Answer:
b. 18m/s
Explanation:
Vi(initial velocity) = 30m/s
a(acceleration) = -4m/s^2
t(time) = 3 sec
i dont understand wat ur tryna say ma dude but whatever it is its.............PIZZA
Answer:
<em>1988.05 rad/s^2</em>
<em></em>
Explanation:
The angular speed of the optical disk ω = 998.0 rad/s
the time taken to come to rest t = 0.502 s
The magnitude of the average angular acceleration ∝ = ω/t
∝ = 998.0/0.502 = <em>1988.05 rad/s^2</em>
A continuous spectrum contains all the wavelengths
A discontinuous spectrum has strips of specific colors and can be used to identify the elements making it.
hope this helps
