<span>An imaginary line perpendicular to a reflecting surface is called "a normal" (principle line)
So, Your Answer would be Option B
Hope this helps!</span>
The resultant speed of the plane is (3) 226 m/s
Why?
We can calculate the resultant speed of the plane by using the Pythagorean Theorem since both speeds are perpendicular (forming a right triangle).
So, calculating we have:


Hence, we have that the resultant speed of the plane is (3) 226 m/s
Have a nice day!
Answer:
Distance piston B = 3 [in]
Explanation:
This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
We know that the volume is equal to the product of an area by a length
![V_{A}=V_{B}\\A_{A}*d_{A}=A_{B}*d_{B}\\2*6=4*d_{B}\\d_{B}=12/4\\d_{B}=3[in]](https://tex.z-dn.net/?f=V_%7BA%7D%3DV_%7BB%7D%5C%5CA_%7BA%7D%2Ad_%7BA%7D%3DA_%7BB%7D%2Ad_%7BB%7D%5C%5C2%2A6%3D4%2Ad_%7BB%7D%5C%5Cd_%7BB%7D%3D12%2F4%5C%5Cd_%7BB%7D%3D3%5Bin%5D)
If a food worker realizes that food is being kept at the incorrect temperature, he or she should immediately report it to their manager and politely request the customer to allow them some time to remake their order because it has been messed up.
The USFDA requires that hot foods should be held at 57 °C (135 °F) or above in order to ensure safety.
