Answer:
Explanation:Remember that c is always about 300,000 km/s. Use the formula you identified to explain how the two factors in the formula are related on the electromagnetic spectrum.
Answer:
2.70 M.
Explanation:
Molar mass of MgO = 24.3 + 16 = 40.3.
A molar solution will contain 40.3g in 1 Litre.
So 800 mL of 1 molar solution will contain 0.8* 40.3 g MgO.
So the molarity of the given solution
= 87 / (0.8*40.3)
= 2.699 M.
Answer:
Point C
Explanation:
Point C has the greatest potential energy because it is at that point that the riders will have maximum height
Answer:
The pressure of the gas after getting compressed is 1.92 L.
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(At constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:

Putting values in above equation, we get:



The pressure of the gas after getting compressed is 1.92 L.
It seems that you have missed the given options for this question which are the following: <span>A. glacial striations B. terminal moraines C. eskers D. cirques
Anyway, the correct answer would be option B. The one that are formed as glaciers retreat and leave debris behind in mounds at the front of their farthest advance are terminal moraines. Hope this answer helps.</span>
