The answer is True. You can speed up chemical reactions by using a recyclable substance called a reactant.
Newton´s thrid law of motion states that:
Every action has an equal and opposite reaction.
c. equal, opposite.
Answer:
Explanation:
A lack of gravity would eventually take its toll on our very planet, writes Masters. "Earth itself would most likely break apart into chunks and float off into space. Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in a titanic explosion
Answer:
2 min 40 s.
Explanation:
Distance = 800 ft
Speed (walking speed) = 300 ft/min
Speed = distance/time
Time, t = 800/300
= 8/3
= 2 min 40 s.
Answer:
1.1259*10^9 Newton per Columb
Explanation:
the magnitude of the electric field intensity can be calculated using the expresion below;
E=Kq/r^2
Where k= constant
q= electric charge
r=distance= 2cm= 20*10^-2m( we convert to m for unit consistency
:,K=59*10^9 Columb
If we substitute the value into above formula we have
E=(9*10^9)*(5*10^-3)/(20*10^-2)^2
=1.1259*10^9 Newton per Columb
Therefore,the magnitude of the electric field intensity in vacuum at a distance of 20 cm is 1.1259*10^9 Newton per Columb
