Fashion21, Wind is cause by air being heated by the sun, you should know being in College, Heat rises, which causes the hot air to rise and the colder air to sink down to take its place, While the air sinks the air rushing down causes what we call wind. So the sun is the main reason we have wind because it is efficient at heating the air. At night due to the lack of heat, wind is somewhat little or no wind active.
Answer:
d = 4.47 [m]
Explanation:
To solve this problem we must make a free body diagram, where we can see the direction of the force acting with the appropriate angles. In the attached image we can see the free body diagram mentioned.
So in the image, we can see an angle of 65° with respect to the horizontal, therefore we can calculate the horizontal component of the force.
Fx = 22.4*cos (65)
Fx = - 9.46 [N] (it's negative because the force is pointing in the negative direction).
We can obtain the same result using 115° as the angle.
Fx = 22.4*cos (115)
Fx = 9.46 [N]
Now we know that work is defined as the product of the force by the distance, therefore we have.
Note: Always the work must be calculated with the force parallel
to the movement
W = F*d
Where:
W = work = 42.3 [J] (units of joules)
F = force parallel to the movement = 9.46 [N]
d = distance [m]
d = W/F
d = 42.3/9.46
d = 4.47 [m]
When it not to hot it just rite
Answer:v=0.0485m^3/kg
Explanation:
PV=MRT
PV/M=RT
Pv=RT
P=8.5mpa= 850Kpa
T= 139K
v= RT/P
0.2968*139/850
v=0.0485m3/kg
Error
0.0485-0.002002/0.0485*100%
95%
540 meters should be the answer
