Answer:
The combined speed of the woman and the skateboard is 6.67 m/s.
Explanation:
It is given that,
Mass of woman, m₁ = 60 kg
Speed of woman, v = 10 m/s
The woman jumps onto a giant skateboard of mass, m₂ = 30 kg
Let V is the combined speed of the woman and the skateboard. It can be calculated using the conservation of momentum as :
On solving the above equation we get V = 6.67 m/s
So, the combined speed of the woman and the skateboard is 6.67 m/s. Hence, this is the required solution.

Below is an attachment containing the solution.
Answer:
Explanation:
The volume charge density is given by:
where
q is the charge
V is the volume of the sphere
In this problem, we have:
is the charge
is the radius of the sphere, so its volume is
So, the volume charge density is
