Answer:
The term 'mettaloid' is normally applied to a group of between six and nine elements ;
- Boron
- Silicon
- Germanium
- Arsenic
- Antimony
- Tellurium, and possibly
- Bismuth
- Polonium
- Astatine
are found near the center of the P-block or main block of the periodic table.
Explanation:
V = I • R
V = (0.054 A) • (152 ohms)
V = 8.208 volts
None of the listed choices is correct.
Frequency and wavelength are two variables which are
indirectly proportional.
They are related in the following equation:
f = c / w
Where,
<span>f = frequency c =
speed of light w = wavelength</span>
Since c is constant, we can equate condition 1 and
condition 2:
f1 w1 = f2 w2
When w2 = 3 w1, then f2 becomes:
261.63 w1 = f2 (3 w1)
Cancelling w1:
f2 = 261.63 / 3
<span>f2 = 87.21 Hz</span>
Answer:
Explanation:
0°Κ = -273.15°C = -459.67 °F
1 °K = 9/5 °F
a) 75.6 - 273.15 = -197.55 °C
b) -459.67 + 75.6(9/5) = -323.59 °F
