Using the impulse-momentum theorem and taking this down as positive, we will get:
FΔt = Δp
F = Δp / Δt
= m(v - v₀) / t
= 0.056kg [13m/s - (- 20m/s) / 0.00125s
= 1478.4 N when properly rounded off is the answer we are looking for in this problem.
Answer:
The larger constant goes to the spring with the largest F/x ratio, this is by measuring a larger Force or by displacing less from the equilibrium position
Explanation:
Using Hooke's Law we have that for each spring the following relations is fulfilled:
Where F is the restoring force (opposite to displacement ergo the negative sign), k is the constant and x is the displacement.
All we need to do is to compare the following:
The larger constant goes to the spring with the largest F/x ratio, this is by measuring a larger Force or by displacing less from the equilibrium position
If you have numerical data we can run the calculations
Answer:
The charge is
Explanation:
From the question we are told that
The mass of each ball is
The distance of separation is
Generally the weight of the each ball is mathematically represented as
where g is the acceleration due to gravity with a value
substituting values
Generally the electrostatic force between this balls is mathematically represented as
given that the the charges are equal we have
So
Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force
So we have
=>
