Explanation:
Fnet = ma = (3kg)(8m/s²) = 24N.
50N - 24N = 26N.
Hence the frictional force is 26N.
Answer:
the comparison of known quantity to unknown quantity or standard guantity is called measurment
The north Celestial pole is 42.036 degrees above the northern horizon when I look at it from my front yard.
I don't need to know my latitude to discover that, since I can measure it directly in the sky.
But when I DO look up my latitude, it blows my mind ! It's the exact same number ... 42.036 degrees north ! This can't be just a coincidence. There must be some connection !
(YOU can't use this number. It's different where you live.)
Answer:
All matter contained electrons
Explanation:
The discovery and characterization of cathode ray suggested that it was a subatomic particle and cathode ray ( electron) was the first discovered. It immensely became the strong explanatory tool for chemical bond. This can be attributed to the the ease with which electron move from one atom to the other.
Explanation:
to provide a stable base load of energy
