Answer:
36 joule
Explanation:
The formula of kinetic energy is 1/2 mv2.
Answer:
D. Left
Explanation:
The question is worded weirdly, but based on the fact that heat transfers from hot to cold and the temperature on the right is warmer than the temperature on the left, I would say that the heat is flowing from the box on the right to the box on the left.
I hope this makes sense and was helpful! ☺
Answer:
Δx is the path difference between the two waves.
...
Phase Difference And Path Difference Equation.
Formula Unit
Phase Difference \Delta \phi=\frac{2\pi\Delta x}{\lambda } Radian or degree
Path Difference \Delta x=\frac{\lambda }{2\pi }\Delta \phi meter
There is an easy and convenient technique to solve vectors without drawing them. With you scientific calculator, make sure that you are in mode CMPLX. In this case, the two vectors should sum up to the resultant vector. Since we are given with the resultant vector, let's just use subtraction. Input this into your calculator:
96.3∠75.2° - 56.4∠232°
The answer would be 59.32+137.55i. Convert this to the r∠θ format. The final answer would be 149.8∠66.67°. Therefore, the second displacement is 149.8 cm and makes an angle of 66.67° with the +x axis.
