Answer:
Explanation:
Time to cover first 100 km = 1 hour.
time remaining = 3.15 - 1 = 2.15 hour .
Time to cover next 42 km = 1 hour .
Time remaining = 2.15-1 = 1.15 hour.
Distance to be covered = 310 - 142
= 168 km
least speed needed = distance remaining / time remaining
= 168 / 1.15
= 146.08 km / h .
The atmosphere is made up of layers which vary in temperature and other characteristics.
<h3>Layers of the atmosphere</h3>
The atmosphere is divided into several layers. The atmosphere refers to the thin layer of air that lies above the earth crust. The following describes the layers of the atmosphere.
- The troposphere refers to the layer where weather changes largely occur and clouds form.
- The stratosphere has an average temperature of about 270 K (−3°C or 26.6°F). The ozone layer is found in the stratosphere.
- The temperature in he mesosphere is about − 85°C (− 120°F).
- The thermosphere has a temperature of 200° C (360° F). The ionosphere is found within the thermosphere.

Answer:
The magnitude of the electric field inside the membrane is 8.8×10⁶V/m
Explanation:
The electric field due to electric potential at a distance Δs is given by
E=ΔV/Δs
We have to find the magnitude electric field in the membrane
Ecell= -ΔV/Δs
The magnitude of the electric field inside the membrane is 8.8×10⁶V/m
Answer: Matter is made up of atoms that also come together to form molocules. Atoms contain Electrons (Negetive), nutronons (nuaetral), and protons (positive).
I'm pretty sure the answer to your question is water because water particles are very close together but don't stay the same shape
