why does our nose get stuffy when we have a cold
Answer:
Due to dilation of blood vessels in the sinuses of the nose
Explanation:
Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.
We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.
- During cold, blood vessels dilate so as to allow for more inflow of blood.
- Incoming blood brings in more heat to the body parts.

Answer:
<h3>C. 6.50 x 10^3</h3>
Explanation:
The satellite revolves around moon due to centripetal force which is provided by gravity in this context so we can equate gravity and centripetal force.

where, m is mass of satellite
M is mass of moon
ω is angular velocity
G is Universal gravitational constant
R is the radius of moon
from the above equation we get ω as,



here M = 7.36 X 10^22
R = 1.738 X 10^6
G =6.67 X 10^-11

T= 6.50 X 10^3 seconds
