The equator would be warmer than the poles. :)
Speed = m/s
Velocity can be negative, but speed cannot.
70 - 68 = 2
2/14 = 0.143 m/s
16. each side length will be 16
As we move from Radiowaves to UV waves in electromagnetic spectrum we know that the wavelength is maximum for radio waves while its frequency is minimum
PART (i)
So as we move from radiowaves to UV region
the Frequency will increase
Part (ii)
As we move from Radiowaves to UV region all the parts must have same speed in same medium
All parts will move with speed of light
so Speed will remain the same
Answer:

Explanation:
When wings of the airplane makes an angle of 40 degree with the horizontal so here we can say that force due to air is having two components


now we know that


also we know that


now plug in all data in above equations
