You have been given the storm's velocity.
Answer:
50 Hz is the answer because 60 m/s divided by 1.2 meters is 50.
Hope that helps you!!! Please give me Brainliest!!!!
Answer:
318.3 nm
Explanation:
We approximate the circular film as a cylinder of height h and radius, r. Its volume V = πr²h. Since this volume equals the volume of the oil drop, the height of the circular film is thus h = V/πr²
V = 10⁻¹⁰ m³ and r = 10 m
Substituting into h, we have
h = 10⁻¹⁰ m³/π(10)²
= 0.3183 × 10⁻¹² m
= 3183 × 10⁻⁹ m
= 318.3 nm
Based on radiometric dating of Apollo rock samples, the rocks have been detected to be about 4.5 Billion years old.

Answer:
Explanation:
The missing image of the figure slide is attached in below.
However, from the model, it is obvious that it is in equilibrium.
As a result, the relation of the force and the torque is said to be zero.
i.e.
and 
From the image, expressing the forces through the y-axis, we have:
Also, let the force 
be the pivot and computing the torque to determine 
:
Then:
For the force equation:
where:
Then:
