Answer:
91 km
Explanation:
Draw a picture. The line of sight to the horizon forms a tangent line with the curvature of the Earth. The radius line to that point forms a right angle with the tangent line. So we can use Pythagorean theorem to find the distance.
c² = a² + b²
(6400 km + 0.650 km)² = (6400 km)² + d²
d ≈ 91 km
The time to distance ratio is 2.1:1 , making the first time 5 seconds, the first distance 18.9 m, and the second time 15 seconds. I hope this helps!
I believe the answer is 'A'
Answer and Explanation:
The rate (in W) at which heat energy moves from the more blazing article to the colder item increments with the temperature distinction between the items.
The more noteworthy the temperature contrast, the more prominent the rate at which exchange of heat energy takes place.
Thus the temperature difference between the beakers relates in the same manner as described above.
The exchange of heat energy continues until a thermal equilibrium is attained.
Answer:
A separation technique to separate solids from a solution. Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system.
