The time required to produce one cycle of a wave is known as the waves

1 answer:

6 0

The time described above is known as the waves Period.
The time which it takes for a particle to complete one full cycle is known as the period. Period is normally measured in seconds. Frequency on the other hand is the number of cycles which are completed in a given period of time e.g a second. periodic time T is given by reciprocal of frequency (1/f).

A 25kg chair initially at rest on a horizontal floor requires a 165 N horizontal force to set it in motion. Once the chair is in

SCORPION-xisa [38]

Answer:

$\mu_k=0.51$

Explanation:

Given that

Mass , m = 25 kg

We know that when body is in rest condition then static friction force act on the body and when body is in motion the kinetic friction force act on the body .That is why these two forces are given as follows

Static friction force ,fs= 165 N

Kinetic friction force ,fk = 127 N

If the body is moving with constant velocity ,it means that acceleration of that body is zero and all the forces are balanced.

Lets take coefficient of kinetic friction = μk

The kinetic friction is given as follows

fk = μk m g

Now by putting the values

127 = μk x 25 x 9.81

$\mu_k=\dfrac{127}{25\times 9.81}$

$\mu_k=0.51$

Therefore the value of coefficient of kinetic friction will be 0.51

What is the difference between virtual images produced by concave, plane and convex mirrors? What does the negative sign in the

vampirchik [111]

Hey.. the virtual image formed by a plane mirror would be the same size. If formed by a convex mirror it would be diminished and if formed by a concave mirror it would be magnified.
the negative sign in the value of magnification indicates the type of mirror, that the mirror being used is convex, and if it is positive then the mirror being used is concave mirror. The negative sign denotes that the image projected is in the inverted direction.
