The F Ring, the Cassini Division, and the C Ring are bright ring features. They are bright due to the low concentration of materials within them, which allows sunlight to shine through.
Answer:
The mechanical advantage is 1.
Explanation:
Given;
input force, F₁ = 10 N
output force, F₀ = 10 N
mechanical advantage is called force ratio and it is given as;
M.A = output force / input force
M.A = 10 N / 10 N
M.A = 1
This is an ideal machine scenario.
Therefore, the mechanical advantage is 1.
Answer:
c
Explanation:
c. This can be either a converging or diverging lens, as more information is needed for a final determination.
A) 222 N/m
Explanation:
Hook's law gives us the relationship between force (F), displacement with respect to the original length (x) and spring's constant (k):
In this part of the problem, we have:
F = 120 N - 100 N = 20 N is the new force applied
x = 9.0 cm = 0.09 m is the displacement relative to the initial stretched position
Solving the equation for k, we find the spring constant
B) 45 cm
We can use Hook's law also for this part of the exercise:
where this time we have
F = 100 N (the original pull applied)
k = 222 N/m
Solving the equation for x, we find the original displacement:
