Answer:
B. Increasing temperature.
Explanation:
Atmospheric pressure increases with increasing temperature because warm air causes the atmospheric pressure to rise.
Basically, when the molecules contained in air experience a collision, they usually exert forces on one other, and when these molecules become heated, they experience a quick and rapid motion leading to an increased rate of collision. Therefore, as more force is being exerted on the air molecules, the atmospheric pressure tends to rise or increase.
Answer:
1 DC
2 DC
3 DC
4 AC
5 DC
Explanation:
AC means alternating current this type of current is not constant I.e time varying
This type of current is being supplied from power lines
DC means direct current and flows at a constant direction. This type of current is being supplied from batteries.
Answer:
A
Explanation:
absolute magnitude and luminosity vs the spectral position/ temperature
Answer: 800 km/h
Explanation:
Use equation for average speed
V=S/t
where S is distance
t is time
S=4800Km
t=6h
---------
V=S/t
V=4800Km/6h=800 Km/h
