why is there potential for wind energy in the upper himalayanx
Answer:
Favorable sites include the tops of smooth, rounded hills; open plains and water; and mountain gaps that funnel and intensify wind. Wind resources are generally more favorable for electricity generation at higher elevations above the earth's surface

Find the x and y components of each of the following vectors.
hyp = 15 m/s
theta = 150°
x = ?
y = ?
Answer:
x =
[tex] - 15 \times \frac{ \sqrt{3} }{2} \frac{m}{s} [/tex]
y = 7.5m/s

Explanation:
A piano tuner creates an 880.0 Hz tone.
When he plucks a piano string, the two
waves create a beat frequency of
5.0 Hz. The string could have two
possible frequencies. What is the
highest value it could have?
(Speed of sound = 343 m/s)
(Unit = Hz)
885 hz for the highest
875 hz for the lowest
acellus correct
10dm/s=...m/phút=......km/h
50km/h =....m/s=...cm/phút
20m/s=....km/phút=....dm/h
200km/h =...nút=...cm/s
Name an acid which is highly corrosive and should never be tested by mouth.
Answer:
We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach
It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.
HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.

Density of Solids Lab Report
3. What methods are you using to test this (or each) hypothesis?
Answer:
The best method to test this with is the buoyancy technique. The buoyancy technique puts force on an object that is equal to the weight of the fluid replaced by the object.
Hope this helps :D
density of certain liquid is2.4 g/cc. calculate the mass of 100cc of such liquid
Answer:
Explanation:
Density = mass / volume
density = 2.4
volume = 100 cm^3
2.4 = m / 100 Multiply both sides by 100
2.4 * 100 = m
m = 240 grams
discuss one way in which global warming aggravates the effect of radiation
One way by which global warming aggravates the effect of radiation is through greenhouse effect
The combined effects of global warming and radiation is explained as follows.
Global warming is the gradual increase in the temperature of the Earth's surface (land), ocean and the atmosphere through the heat from the radiation of the sun.
One way by which global warming aggravates the effect of radiation is through greenhouse effect.
This occurs when the radiation from the sun is allowed to pass into the Earth's atmosphere but subsequent heat radiating from the Earth is prevented from escaping into the space.This greenhouse effect aggravates the effect of radiation.
