Well I have 2 examples.
AM/FM radio is a perfect type of technology.
A smart phone is also a great presentation of technology.
35°F=1.666667℃
75°F=23.88889℃
The temperature change is 22.222223°C
Answer:
so therefore, the comb gains electron and the hair losses electrons
Explanation:
It is known that electron contain a negative charge.
So, when an atom gain electrons then number of electrons within the atom increases. As a result, the atom acquires a negative charge.
But when an atom loses electrons, there will be deficiency of electrons within the atom. As a result, the atom becomes positively charged.
Hence,, when people use plastic combs on their hair, the combs become negatively charged. The situation which is true about this is the comb gains electrons and the hair loses electrons.
Force = mass x acceleration
F = ma
500 = 35a
a = 500/35 = 14.28 m/s
Answer:
-22/15
Explanation:
the least common denominator is 15 so first you multiply -2/3 by 5 in both the numerator and denominator making it -10/15
Then you do the same to -4/5 except you multiply the numerator and denominator by 3 giving you -12/15
If you add -10/15+ -12/15 you get -22/15
