The answer is true. The blowing fan force the hot air to go through the process of convection .
Velocity = displacement / time
displacement = velocity × time
d = 29 ms⁻¹ ˣ 8.4 s
d = 243.6 m
Answer:
A correlation coefficient represents the following:
1- The direction of the relationship
2- The strength of the relationship
Vx=cos60(4)
x-component of velocity
If you think about it, it makes a right triangle when you combine all the different types of forces together such as v, vx and vy. Then, you can use trigonometry and soh cah toa in order to figure out vx.
