There are other forces at work here nevertheless we will imagine
it is just a conservation of momentum exercise. Also the given mass of the
astronaut is light astronaut.
The solution for this problem is using the formula: m1V1=m2V2 but
we need to get V1:
V1= (m2/m1) V2
V1= (10/63) 12 = 1.9 m/s will be the final speed of the astronaut after
throwing the tank.
Wave energy is actually a concentrated form of solar power generated by the action of the wind blowing across the surface of the oceans water which can then be used as a renewable source of energy. As the suns rays strike the Earth's atmosphere, they warm it up.
The circuit change when the wire is added will see a short circuit occur and makes bulbs 1 and 2 turn off but keeps bulbs 3 and 4 lit. Option D. This is further explained below.
<h3>
How does the circuit change when the wire is added?</h3>
Generally, Electronic circuits consist of a series of interconnected parts that form a closed loop through which electricity may flow.
In conclusion, If two wires are linked together, a short circuit will develop, cutting power to bulbs 1 and 2. But there is no impact on bulbs 3 and 4. There is no problem with bulbs 3 and 4.

The correct answer is - 75-80%.
The haze is a hazardous occurrence. It is a slight obscuration of the lower atmosphere, and the cause for its occurrence are the fine suspended particles. Thus we can conclude that the haze is actually caused by pollution of the air.
While the haze typically is a dry air phenomenon, it can also be a wet one if the conditions are right, though that happens relatively rarely. If the humidity in the air is 75-80% than the tiny aerosol particles of the dry haze start to act as condensation nuclei, resulting in a wet haze.
Answer:
A) Rapidez
Explanation:
Speed is a scalar quantity and it is found by dividing the distance traveled by the time taken.
Speed =
Distance is the length of path covered whereas time is the duration of the travel.
Unlike velocity which is a vector, speed is a scalar quantity with only magnitude but no direction.
