This is because in 1918 there was a law created to save birds. It was the Migratory Bird Treaty act
Answer: They’d fall at the same speed, because air resistance is the only thing that makes an object fall faster than another. There’s a video somewhere on the internet of a bowling ball and a feather falling at the same speed in a vacuum, if you look for it. Hope this helps!
Answer:
1.4 s
Explanation:
Given the following data;
Quantity of charge, Q = 2.5 C
Current = 1.8 A
To find the time required;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
2.5 = 1.8 * time
Time = 2.5/1.8
Time = 1.4 s
Answer:
(a) t = 5.66 s
(b) t = 8 s
Explanation:
(a)
Here we will use 2nd equation of motion for angular motion:
θ = ωi t + (1/2)∝t²
where,
θ = Angular Displacement = (3.7 rev)(2π rad/1 rev) = 23.25 rad
ωi = initial angular speed = 0 rad/s
t = time = ?
∝ = angular acceleration = 1.45 rad/s²
Therefore,
23.25 rad = (0 rad/s)(t) + (1/2)(1.45 rad/s²)t²
t² = (23.25 rad)(2)/(1.45 rad/s²)
t = √(32.06 s²)
<u>t = 5.66 s</u>
<u></u>
(b)For next 3.7 rev
θ = ωi t + (1/2)∝t²
where,
θ = Angular Displacement = (3.7 rev + 3.7 rev)(2π rad/1 rev) = 46.5 rad
ωi = initial angular speed = 0 rad/s
t = time = ?
∝ = angular acceleration = 1.45 rad/s²
Therefore,
46.5 rad = (0 rad/s)(t) + (1/2)(1.45 rad/s²)t²
t² = (46.5 rad)(2)/(1.45 rad/s²)
t = √(64.13 s²)
<u>t = 8 s</u>
Answer:
A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons
