Latitude is a geographical coordinate that is used to locate the north and the south position of a location on the earth's surface.
Explanation
- Latitude can be defined as an angle that varies from 0 degree at the equator to 90 degree at the poles.
- Latitude affects the temperature of the earth in the following ways :-
- As a person moves away from the equator the temperature of the regions away from the equator falls this is because the region receives less sunlight.
- The shape of the earth is not round it is spheroid that is the reason all the regions on the surface of the earth do not receive the same amount of sunlight.
From the above given options the 2 correct choices are
- Latitude determines the duration of the day:The areas at the equator (i.e at 0 degree latitude) the length of the day is said to be 12 hours,now as the latitude increases to 80 degree (i.e at the polar circles) the length of the day increases to 24 hours or decreases to zero.
- Latitude creates Polar and temperate zones:There are three types of latitude zones-Arctic,temperate and tropic zone.Latitude is considered as an important parameter in the classification of zones as it correlates to the amount of sunlight a region receives.
Answer:
No. Gender traits in humans are largely determined by biophysical processes.

Answer:
![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
Explanation:
Total force = Force due to gravity + Force due to charges
Total force = ![\frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGMm%7D%7Br%5E%7B2%7D%20%7D%20%2B%20%5Cfrac%7BkQq%7D%7Br%5E%7B2%7D%20%7D)
r is the separation between particles.
Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs
Mass of a proton (M)= 1.67×10^-27 kilograms
Mass of an electron (m) =9.11 × 10^-31 kilograms
G=6.67 ×10^−11 N⋅m^2/kg^2
k=8.99 * 10 ^9 N.m^2 / C^2
Plugging in values:
Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2
Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2
We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.
Total force = Force due to charges.
F = 2.3 *10^-28 / r^2
r = ![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
Answer:
wave A has a higher frequency then wave b
Explanation:
test
<span>A certain virus infects one in every 200 people. A test used to detect the virus in a person is positive 90% of the time if the person has the virus and 5% of the time if the person does not have the virus. (This 5% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive".
