Answer:
hope it helps you.................
The ball should take twice as long to return to its original position as it took to reach its maximum height, so it should return to its original position at 
.
Answer:
D) the difficulty in expanding capacity by adding servers and clients
Explanation:
The limitation of the current Internet are as follows
1.The speed of the internet.When the number of user used the same internet then the speed of the internet decrease.
2.The band with is limited.
3.Continued reliance on cables and wires for connectivity
So the option d is correct.
D) the difficulty in expanding capacity by adding servers and clients
Answer: 2.3 x 10^-7
Explanation:
When you move the decimal to the right, you decrease the exponent. So lets count how many spots you have to move the decimal spot to get an answer between 1 and 10. I counted seven spots.
So:
Answer:
α = 5 10⁻³ rad / s²
Explanation:
For this exercise we can use Newton's second law for rotational movement, where the force is electric
τ = I α
Where the torque is
τ = F x r = F r sin θ
Strength is
F = q E
The moment of inertia of a small ball, which we approximate to a point is
I = m r²
We replace
2 (q E) r sin θ = 2m r² α
The number 2 is because the two forces create the same torque
α = q E sin θ
/ m r
Let's reduce the magnitudes to the SI system
m = 1.0g = 1.0 10⁻³ kg
L = 2.0 cm = 2.0 10⁻² m
q = 10 nc = 10 10⁻⁹ C
E = 1.0 10 N / C
r = L / 2
r = 1.0 10⁻² m
Let's calculate
α = 10 10⁻⁹ 1.0 10 sin 30 / 1.0 10⁻³ 1.0 10⁻²
α = 5 10⁻³ rad / s²
