1. Wind speed is 150 km/h, or 42 m/s Velocity of 2 x 4 =
m/s
Force exerted by 2 x 4 on wall =
N
2. Wind speed is 325 km/h, or 90 m/s
Velocity of 2 x 4 =
m/s
Force exerted by 2 x 4 on wall =
N
3. What force is exerted by the wall on the 2 x 4 board when wind speed is 150 km/h?
Force exerted on 2 x 4 =
N

Witch one is it soo it the the question b.a,b,c,d

Why is the huronian supergroup rock formation particularly interesting to scientists? because it looks like a cross-section of a giant, stone encyclopedia because it formed during the period when oxygen began to accumulate in the atmosphere because it contains unusually large amounts of oxygen and sulfur because it dramatically altered the planet's development when it first formed
