Answer: Infrared light
Explanation:
Infrared light is an electromagnetic radiation which has longer wavelength than visible light.
cool and faint objects are difficult to be detected using visible light.
Infrared light can pass through dust and clouds of gases. Thus, it is the best way to study the young stars hidden behind interstellar dust clouds.

Answer:
30%
Explanation:
Total profit=$25000
Initial investment=$10000
Return on investment is given by
RoI=(Gain from investment-cost of investment)/cost of investment
RoI=150% but since it's over 5 years, we distribute for 5 years hence annual 
Therefore, RoI=30%
A machine that provides both constant speed and maximum resistance throughout the full range of motion provides an isokinetic type of muscular contraction. This type of contraction occurs when the muscle would contract and shorten at a consistent and constant speed. To have this contraction, special equipment are to be used. An example of an equipment would be an <span>Isokinetic Dynamometer. </span>However, this type of training is said to be one of the fastest in increasing the muscle strength and the muscle endurance. With this training, the muscles being targeted would gain strength consistently and evenly throughout the whole duration of exercise.
