Answer:
Correct answer: E total = 2,800 J
Explanation:
Given:
m = 4 kg the mass of the object
V = 20 m/s the speed (velocity) of the object
H = 50 m the height of the object above the surface
E total = ? J
The total energy of an object is equal to the sum of potential and kinetic energy
E total = Ep + Ek
Ep = m g H we take g = 10 m/s²
Ep = 4 · 10 · 50 = 2,000 J
Ek = m V² / 2
Ek = 4 · 20² / 2 = 2 · 400 = 800 J
E total = 2,000 + 800 = 2,800 J
E total = 2,800 J

Answer:
C. Both of A and C
Explanation:
Primary colors are colors that can be combined with one another to form other colors called secondary colors.
Light can be defined as a phenomenon that causes the sensation of vision. The primary colors with regards to light are: red, green and blue. Light is a form of an additive system where there is an addition of two or more primary colored lights to form other colors.
Paints are subtractive systems that produce color due to absorption and reflection of colors. A green paint appears green because it has absorbed other colors and reflects only green. Its primary colors are blue, yellow and green.
Therefore, paints reflect light and take out light from what light is shined onto them.
