Answer:
B.7.5m/s2
Explanation:
average acceleration=change invelocity/time taken
a=(60-30)/4
=7.5m/s2
Energy is released or absorbed ,but no loss in total molecules,each of which consists of one atom of oxygen and two of hydrogen,are broken down.!
Answer:
Equivalent resistance in series = 6 + 3 = 9 ohms
Current = V/R (ohm's law)
Current = 9/9 = 1 A
P.D. across 6 ohms = IR (ohm's law)
= 1A × 6Ω = 6V
It’s the second one because tahst like close to 4.8 so
The models are used to represent what you are studying in this case would be a planet. A model of Saturn and its rings and the moons surrounding it would be fantastic to look at when you have no way of going there
