Yes Darter eats plankton and mussels.
I'm afraid you're not paying attention. This question is loaded with
all the important words, and you don't recognize Newton's second
law of motion. Didn't you notice the "force", "acceleration", and
"mass" all over the place in there ?
Newton's 2nd law: Force = (mass) x (acceleration)
The answer is going to be 'mass', so let's divide
each side of Newton's law by 'acceleration':
Mass = (force) / (acceleration)
Now, just write in the numbers that the question gave you:
force = 60 newtons
acceleration = 4 m/s²
Here's the equation again: Mass = (force) / (acceleration)
= (60 N) / (4 m/s²)
= 15 kg .
Answer:
The compression of the spring is 24.6 cm
Explanation:
magnitude of the charge on the left, q₁ = 4.6 x 10⁻⁷ C
magnitude of the charge on the right, q₂ = 7.5 x 10⁻⁷ C
distance between the two charges, r = 3 cm = 0.03 m
spring constant, k = 14 N/m
The attractive force between the two charges is calculated using Coulomb's law;

The extension of the spring is calculated as follows;
F = kx
x = F/k
x = 3.45 / 14
x = 0.246 m
x = 24.6 cm
The compression of the spring is 24.6 cm
