Answer:
a_total = 2 √ (α² + w⁴)
, a_total = 2,236 m
Explanation:
The total acceleration of a body, if we use the Pythagorean theorem is
a_total² = a_T²2 + 
²
where
the centripetal acceleration is
a_{c} = v² / r = w r²
tangential acceleration
a_T = dv / dt
angular and linear acceleration are related
a_T = α r
we substitute in the first equation
a_total = √ [(α r)² + (w r² )²]
a_total = 2 √ (α² + w⁴)
Let's find the angular velocity for t = 2 s if we start from rest wo = 0
w = w₀ + α t
w = 0 + 1.0 2
w = 2.0rad / s
we substitute
a_total = r √(1² + 2²) = r √5
a_total = r 2,236
In order to finish the calculation we need the radius to point A, suppose that this point is at a distance of r = 1 m
a_total = 2,236 m
Explanation:
Photovoltaic energy is a clean, renewable source of energy that uses solar radiation to produce electricity. It is based on the photoelectric effect—the emission of electrons when electromagnetic radiation (i.e. light) hits a material.

Answer:
7. Net force: 14 N
Direction: Right
8. Net force: 360 N
Direction: Right
Explanation:
For Nm 7 the most force is on the right side so it has more power then left side and so its gonna pull towards the right side cancelling the force on the left. So it becomes 26-12 N = 14N
For Nm 8 all the force is on the right side so they add up.
