In the first shell there can be a maximum of 2 electrons, then 8o in the second one and 8 in the third one.
Answer:
148(m/s)
Explanation:
V_final = V_current + (acceleration) x (time)
= 4 + 80 x 1.8 = 148 (m/s)
Answer:
114.075 N
798.525 Nm
Explanation:
C = Drag coefficient = 0.5
ρ = Density of air = 1.2 kg/m³
A = Surface area = 9 m²
v = Velocity of wind = 6.5 m/s
r = Height of the tree = 7 m
Drag equation

Magnitude of the drag force of the wind on the canopy is 114.075 N
Toque is given by the product of force and radius

Torque exerted on the tree, measured about the point where the trunk meets the ground is 798.525 Nm
Answer:
c - until it becomes a different, stable element

Answer:
Option B is the correct answer.
Explanation:
Let us consider 40 meter above ground as origin.
Initial velocity = 17 m/s
Final velocity = 24 m/s
Acceleration = 9.81 m/s
We have equation of motion v² = u² + 2as
Substituting
24² = 17² + 2 x 9.81 x s
s = 14.63 m
Distance traveled by rock = 14.63 m down.
Height of rock from ground = 40 - 14.63 = 25.37 m = 25.4 m
Option B is the correct answer.
