State Newton's second law ofmotion and write downthree examples tojustity it.
1 answer:
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
f= force
m=mass
a=acceleration
Explanation:
examples:
riding your bicycle
•your bicycle is the mass, your leg pushing in pedals of your bicycle is the force
pushing a box
•the box is the mass, you are pushing the box
setting a pencil down in a table
•the pencil is the mass, you are puting the pencil down

when object is placed on inclined plane then we will have net force along the inclined plane which is due to the component of weight along the incline
so we can say that
now in order to find the acceleration we can use Newton's II law
and the direction is along the inclined plane downwards as weight always pull downwards
So correct answer will be
<em>B)4.0m/s2, directed down the slope</em>
Given:
The length of the string is l = 6 m
The speed of the wave is
Required: Lowest possible frequency for the standing wave.
Explanation:
The lowest possible frequency is the fundamental frequency.
The fundamental frequency can be calculated by the formula
On substituting the values, the fundamental frequency will be
Final Answer: The lowest possible frequency for standing waves on this string is 16.67 Hz
