Here two vectors are given of lengths
now let say the two vectors are inclined at some angle with each other
so the resultant is given as
now plug in all values
Now for maximum resultant the angle between two vectors must be ZERO degree
Now for minimum resultant the angle between two vectors must be 180 degree
Answer:
It's D. The geothermal energy from Earth's core loses most of its heat before reaching the outer layer. The plates on the outer layer have been proven to be moving due to evidence such as earthquakes, volcanic eruptions, and tsunamis.
Explanation:
Larger than one.
In fact, the index of refraction of a medium is the ratio between the speed of light in vacuum (c) and the speed of light in that medium (v):
But the maximum speed the light can travel at is exactly c, the speed of light in vacuum: so v is always less (or equal, in case of vacuum) than c, and so n is always greater than 1.
Answer:
Length of the string, l = 0.486 meters
Explanation:
It is given that,
Mass of the string,
Tension in the string, T = 120 N
Frequency of transverse wave, f = 260 Hz
Wavelength of the wave,
The speed of a transverse wave (v) is given by :
........(1)
<em>Where,</em>
Also, speed of a wave, .........(2)
From equation (1) and (2) :
l = 0.486 m
So, the length of the string is 0.486 meters. Hence, this is the required solution.
