False because light microscopes have low resolve and magnification.
Answer:
Formula for constant-speed = Total distance / Total time taken
Explanation:
Answer:
dr/dt = -2 cm/s.
Explanation:
The volume of a cone is given by:
(1)
- r is the radius
- h is the height
Let's take the derivative with respect to time in each side of (1).
(2)
We know that:
- dh/dt = 10 cm / s (rate increasing of height)
- dV/dt = 0 (constant volume means no variation with respect of time)
- r = 4 cm
- h = 10 cm
We can calculate how fast is the radius changing using the above information.
Therefore dr/dt will be:
The minus signs means that r is decreasing.
I hope it helps you!
Answer:
15
Explanation:
The mass number is defined as the total number of protons and neutrons. The atomic number is total number of protons. And since we have the mass number and number of neutrons, we can use simple subtraction (30 - 15) to find that the atomic number is 15.
Answer:
Monitoring reader comments and engagements, mini research about the demographics of previous edition, an online survey
Explanation:
The more she understands the background and need of her audience, the better her speech and coherence will be .
Some ways to discover her audience are:
