Iron filings sprinkled near a magnet arrange themselves into pattern that illustrate the Magnetic fields. Magnetic fields are both about illustrate electric currents and magnetic materials. That's the reason why the iron filings arranges themselves into pattern when sprinkled near a magnet.
Answer:
d) the object gets bluer
blue wavelengths are shorter than red wavelengths (in the visible spectrum)
blue light will carry more energy than an equivalent amount of red light
Answer:
Natural science is concerned with the description, prediction, and understanding of natural phenomena based on empirical evidence from observation and experimentation. It can be divided into two main branches: life science (or biological science) and physical science.
Explanation:
The energy associated with the stone from a height of 7.70 m can be calculated by multiplying the mass, gravitational acceleration and height. We do as follows:
Energy = mgh
Energy at 7.70 m = m(9.81)(7.70) = 75.537m
Energy at 5.25 m = 0.5mv^2 =75.537m
v = 12.29 m/s
