Automobiles and Airplanes is what I can think of
Answer:
The correct answer is C) Trimetric
Explanation:
The most suitable answer is a trimetric projection because, in this type of projection, we see that the projection of the three angles between the axes are not equal. Therefore, to generate a trimetric projection of an object, it is necessary to have three separate scales.
Answer:
False I'm pretty sure sorry If its wrong
Answer:
17.799°
Explanation:
When the bullet hits the block at that time the momentum is conserved
So, initial momentum = final momentum
![P_i=P_f](https://tex.z-dn.net/?f=P_i%3DP_f)
So ![28\times 10^{-3}\times 210=(3.6+0.028)v_f](https://tex.z-dn.net/?f=28%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20210%3D%283.6%2B0.028%29v_f)
![v_f=1.6207\ m/sec](https://tex.z-dn.net/?f=v_f%3D1.6207%5C%20m%2Fsec)
Now energy is also conserved
So ![\frac{1}{2}\times (3.6+0.028)\times 1.6207^2=(3.6+0.028)\times 9.81\times 2.8(1-cos\Theta )](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%283.6%2B0.028%29%5Ctimes%201.6207%5E2%3D%283.6%2B0.028%29%5Ctimes%209.81%5Ctimes%202.8%281-cos%5CTheta%20%29)
![cos\Theta =0.8521So\ \Theta =17.799^{\circ}](https://tex.z-dn.net/?f=cos%5CTheta%20%3D0.8521So%5C%20%5CTheta%20%3D17.799%5E%7B%5Ccirc%7D)
