Acceleration due to gravity at the surface of Mars is given by the formula
here
M = mass of Mars
R = radius of Mars
Now if we take a point which is at height 3 times the radius of Mars from its surface
So the acceleration due to gravity is given as
now using this
so here the gravity is 16 times lesser than gravity at surface
If an object is projected with vertical speed given as
now the time of flight of the object that time in which it comes back on ground
now here we will have
now the range of projectile is given as
now here we know that
now the range is given as
now in order to have maximum range we can say
so we will have
so now we can say
so both speed must be same to have maximum horizontal range
Answer:
I = 0.25 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = amperage or current [amp]
R = resistance [ohm]
Since all resistors are connected in series, the total resistance will be equal to the arithmetic sum of all resistors.
Rt = 2 + 8 + 14
Rt = 24 [ohm]
Now clearing I for amperage
I = V/Rt
I = 6/24
I = 0.25 [amp].
Answer:
Explanation:By using the sunglasses while looking at If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below.
Another one is by comparing two sunglasses, hold your glasses and another one simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn't polarized, however, you won't notice any difference.
Also it can be determined by simple computer test If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same also applicable to LCD display screens such as the ones on a gas pump.
Answer:
Part a)
Part b)
Explanation:
Part a)
change in the energy due to decay of photon is given as
here we know that
now we have
Part b)
While electron return to its ground state it will emit a photon of energy 2/3rd of the total energy
so we have
now to find the wavelength we have
