Answer:
it is a because blood is pumped but heart so the answer is A
The answer is A. A falling barometer means a decrease in air pressure. This is caused by an increase in the local temperatures that warm the air and make it less dense. Clouds start forming when the warm humid air starts to rise and cool. The water moisture turns into water droplets.
Answer: 308.649 K
Explanation:
Temperature in Celsius would be converted to Kelvin (K), which is the widely accepted S.I units for measuring Temperature in Chemistry.
Kelvin (K) = 273 + Celcius
= 273 + 35.649 C
= 308.649 K
Answer:
NaCl
Explanation:
Na is the symbol of sodium. Cl is the symbol of chlorine
Answer:
Explanation:
1)The charge of one electron is given by
1 e = - 1.6 * 10-19 C
Then – 1 C = 1 e / ( 1.6 * 10-19 )
= 6.25 * 1018 e
So one-coulomb charge has 6.25 * 1018 electrons
2)Let q1 and q2 be two charges separated by a distance r
Then q1 = - 40 µC = - 40 * 10-6 C
And q2 = 108 µC = 108 * 10-6 C
