Well one is from potential energy to ascensive moving energy . And another is from electrical to circuit energy.
Answer:
Option A
Measures light from distant objects
Explanation:
A spectroscope is used to measure the use of light from a distant object to work out the object is made of.
It could be the single-most powerful tool astronomers use.
Professor Fred Watson from the Australian Astronomical Observatory says that "It lets you see the chemicals being absorbed or emitted by the light source"
Answer: Plenty

The mass of the seashell suspended by the two strands of spider silk is 0.28 kg.
The given parameters:
- <em>Tension on each strand of silk, T = 1.42 N</em>
- <em>Angle of inclination of each strand, θ = 75⁰</em>
The mass of the seashell at equilibrium is calculated by applying Newton's second law of motion;

where;
- W is the weight of the seashell
The weight of the seashell is calculated as;

The mass of the seashell is calculated as follows;

Thus, the mass of the seashell suspended by the two strands of spider silk is 0.28 kg.
