Answer:
2 cm and 6 cm.
Explanation:
The maximum displacement of first square wave pulse is 4 cm and the maximum displacement of second square wave pulse is 2 cm. We need to find a possible displacement of the string when the wave pules overlap.
It could be result in constructive interference or destructive interference.The possible displacement of the string are :
4 cm - 2 cm = 2 cm
4 cm + 2 cm = 6 cm
Hence, the correct options are (A) and (C).
Electromagnetic waves are often called "electromagnetic radiation".
That's a really strong clue.
Heat carried in the form of electromagnetic waves is radiation.
Answer:
Before start of slide velocity will be 14.81 m/sec
Explanation:
We have given coefficient of static friction 
Angle of inclination is equal to 
Radius is given r = 28 m
Acceleration due to gravity 
We know that 
So before start of slide velocity will be 14.81 m/sec
No, bleach is not heterogeneous. Bleach is actually homogeneous.
Heterogeneous is if it the same throughout.
Homogeneous is if it is different (has chunks and clumps of different materials)
Answer:
Newton's First Law of Motion.
Explanation:
Newton's First Law of Motion states that a body continues its state of motion untill and unless an external force acts on it. Here, the truck moves forward even after the breaks are applied in order to maintain its State of motion.
