Answer:
The total charge Q of the sphere is
.
Explanation:
Given that,
Radius = 5 cm
Charge density 
We need to calculate the total charge Q of the sphere
Using formula of charge

Where,
= charge density
V = volume
Put the value into the formula

Put the value into the formula


Hence, The total charge Q of the sphere is
.
Answer:
Her average speed is 0.25 miles / hour.
Explanation:
I did 0.5 divided by 2 = 0.25 miles / hour.

Answer:
α = 0
, w = w₀
Explanation:
Torque is related to angular acceleration by Newton's second law for rotational motion.
τ = I α
Where τ is the torque, I the moment of inertia and α the angular acceleration.
If we apply an external torque for the sum of all torques to be zero, the angular acceleration must fall to zero
α = 0
Since the acceleration is zero, the angular velocity you have at that time is constantly killed.
w = w₀ + α t
w = w₀ + 0
Im not exactly sure but I think the answer is techtonic plates collide
Answer:
Explanation:
Solar energy production encompasses several power sources, both passive and active. It’s important to differentiate among the different types of solar energy production systems since it’s not uncommon for the average homeowner to confuse them. We’ll start with a diagram of solar energy hitting the earth surface.
Then we’ll present diagrams and discuss photovoltaic solar, solar hot water, and concentrated solar power. The easiest way to think about these is: am I using solar energy to heat water (solar hot water and CSP) or am I converting sunlight directly into electricity (photovoltaic cells)?
