I would choose the option B.
F = ma
a = 75 / 25 = 3 m/s^2
Answer:
sorry cant find the answer but i hope you got it right and if you didnt youll still do great

Answer:
hello your question is incomplete attached below is the complete question with the options
answer : Doubling the Diameter increases the heat transfer rate by a factor of 4 ( B )
Explanation:
The heat transfer in the axial direction of the cylinder can be calculated/determined as attached below
= 4 ( This shows that Doubling the diameter increases the heat transfer rate by a factor of 4 )
Answer:
a) Vb = 4.65m/s at 25.46° due south of east
b) t = 119s
c) d = 238m
d) 28.43° due north of east.
e) Vb = 3.69m/s due east
f) t = 135.5s
Explanation:
Velocity relative to the earth is:
Vb = 4.65m/s < -25.46°
Since the distance to travel is 500m:
The distance on the y-axis is given by:
If the final position is directly east from the starting position:
From the y-components:
Solving for β:
β=28.43°
With this angle, the velocity would be:
Vb = 4.2*cos(28.43°) = 3.69m/s
And the time it would take it to cross:
t = 500/3.69 = 135.5s
I'd say the atmosphere plays a role in all of these but if I had to choose one it would be D
