The common value for “Speed of light in vacuum” is metre per second.
Answer: Option b
<u>Solution:
</u>
Speed of light can be defined as the speed with which light waves propagate in different medium. In vacuum, speed of light is 186,282 miles per second or 299,792 km/s which is rounded off as .
“Speed of light in vacuum” is a universal constant and usually represented by ‘c’. Light waves travels at a speed of metre per second in vacuum.
Answer:
I think it is O only nonliving
The catalyst lowers the activation energy.
Answer:
k=19 N/m
Explanation:
Use the equation F=kx for this problem and isolate k since that is what you're solving for (k=F/x). Plug in your values (F=1.2 N and x=0.064 m) and solve for k which is 19 N/m.
