Answer:

Explanation:
Frequency of each electromagnetic wave is same thus we can interfere them along X axis in Phase diagram.
In phase diagram indicate each wave as vector with amplitude as length and phase difference as angle. (shown in attachment)
Now take component of E2 and E3 amplitude along X direction.
Net amplitude of all E in X direction =
+ cos(45)[
+
]
⇒
Final resultant have no change in frequency
So , resultant is 
The truck would of went 150 miles
Answer:
Force, F = 2714.33 N
Explanation:
It is given that,
Diameter of the circular tip, d = 1.2 mm = 0.0012 m
Radius, r = 0.0006 m
Pressure acting on the hammer, 
Let F is the force exerted on a nail. It can be calculated using the definition of pressure exerted. Its formula is given by :



F = 2714.33 N
So, the force exerted on a nail 2714.33 N. Hence, this is the required solution.
