Answer:
low pressure systems
Explanation:
with a low pressure system over the area the storm can't form
Answer:
b) Betelgeuse would be 
times brighter than Sirius
c) Since Betelgeuse brightness from Earth compared to the Sun is 
the statement saying that it would be like a second Sun is incorrect
Explanation:
The start brightness is related to it luminosity thought the following equation:
(1)
where 
is the brightness, 
is the star luminosity and 
, the distance from the star to the point where the brightness is calculated (measured). Thus:
b) 
and 
where 
is the Sun luminosity (
) but we don't need to know this value for solving the problem. 
is light years.
Finding the ratio between the two brightness we get:
c) we can do the same as in b) but we need to know the distance from the Sun to the Earth, which is 
. Then
Notice that since the star luminosities are given with respect to the Sun luminosity we don't need to use any value a simple states the Sun luminosity as the unit, i.e 1. From this result, it is clear that when Betelgeuse explodes it won't be like having a second Sun, it brightness will be 5 orders of magnitude smaller that our Sun brightness.
Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
I think it is D

Conductive deafness refers to a malfunction of the middle ear. Those 3 ossicles (malleus, incus, stapes) are responsible for converting the sound wave and conducting it to the inner ear.
