Answer:
7.99 or 8 depends where you round.
Explanation:
Distance divided by time so 1246/156=7.98717948718
Answer:
s = 30330.7 m = 30.33 km
Explanation:
First we need to calculate the speed of sound at the given temperature. For this purpose we use the following formula:
v = v₀√[T/273 k]
where,
v = speed of sound at given temperature = ?
v₀ = speed of sound at 0°C = 331 m/s
T = Given Temperature = 10°C + 273 = 283 k
Therefore,
v = (331 m/s)√[283 k/273 k]
v = 337 m/s
Now, we use the following formula to calculate the distance traveled by sound:
s = vt
where,
s = distance traveled = ?
t = time taken = 90 s
Therefore,
s = (337 m/s)(90 s)
<u>s = 30330.7 m = 30.33 km</u>
Answer:
<h2>Gravity :</h2><h3>the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.</h3>
<h2>Solar day</h2><h3>A solar day is the time it takes for the Earth to rotate about its axis so that the Sun appears in the same position in the sky.</h3><h2> or</h2><h3>It is the time between successive meridian transits of the sun at a particular place.</h3>
Answer: This is an example of downregulation and upregulation.
Explanation:
Downregulation is a process in which cells decrease the production of one of their components, responding to an external stimulus. Upregulation, on the other hand, is when cells increase the production of one of their components in response to an external stimulus.
In this case, the decrease in insulin receptors would make the cell less sensitive to the hormone.
If there's a lot of insulin around those cells, the cell would have to decrease its sensitivity, otherwise, it would metabolise more glucose than the body needs. The contrary would happen if there was too little insulin around those cells, they would have to become more sensitive to it by increasing the number of receptors.
