perpendicular to the wave motion.
Answer:
Your real dad according to Science and your DNA codes.
A)We know the formula of the angular speed is ω = 2π / TWhere T is the time period.When second hand completes one revolution then the time taken is 60s.So T = 60sThen the angular speed of the second hand is ω= 2π / (60s) = 0.1047 rad/sb)When the minute hand completes one revolution the time taken is T = 1 hr = 3600sThen the angular speed of the minute hand is ω =(2π) / (3600s) = 0.001745 rad/sc)When the hour hand completes one revolution then the timeperiod is T = 12hrs = (12)(3600)sThen the angular speed of the hour hand is ω =(2π) / [(12)(3600)s] = 1.45444 x 10^-4 rad/s
A compound is a substance that consists of two or more elements, which is chemically combined, meaning that it could only be split by chemical means.
Examples:-
- NaCl is salt, chemically combined of Sodium and Chloride.
- H2O is water, chemically combined of Hydrogen and oxygen.
