Our eyes are detectors which are designed to detect visible light waves (or visible radiation). ... The electromagnetic spectrum includes gamma rays, X-rays, ultraviolet, visible, infrared, microwaves, and radio waves. The only difference between these different types of radiation is their wavelength or frequency.
Answer:
(4) The physical and chemical properties of these minerals determine how humans use them.
Explanation:
All the materials and the metals found on earth shows certain characteristics naturally or in their physical state. These physical characteristics can be their look, their structure, their color, strength, melting point, boiling point, density, etc.
And chemical properties of the metals are defined as those characteristics or features of the metals that it exhibits when these metals reacts chemically.
The physical properties as well as the chemical properties distinguishes each metal from each other. These properties determines how people use these metals in their life.
Answer:
0.369 V
<u>Explanation:</u>
Given :
Capacitance ( c ) = 650 × 10–4 F
Charge ( q ) = 24 × 10–3 C
We are asked to find potential difference ( v )!
We know:
q = c v
= > v = q / c
Putting values here we get:
= > v = ( 24 × 10–3 ) / ( 650 × 10–4 ) V
= > v = 240 / 650 V
= > v = 24 / 65 V
= > v = 0.369 V
Therefore, potential difference between the plates is 0.369 V
Answer:
F = 13333.333 N = 13.33 KN
Explanation:
From Newton's second law of motion, the change in momentum = the impulse.
Mathematically,
Impulse = Change in momentum.
Impulse = (Force) × (time during which it acts) = F.t
Magnitude of the Change in momentum = mv (there is no final momentum as the paint sticks to the spacecraft window)
F×t = m×v
t = (6.00 ✕ 10⁻⁸) s
m = 0.160 mg = (1.6 × 10⁻⁷) kg
v = (5.00 × 10³) m/s
F × (6.00 ✕ 10⁻⁸) = 1.6 × 10⁻⁷ × 5.00 × 10³
F = 13333.333 N = 13.33 KN
Hope this Helps!!!
