Frequency of any wave = (speed) / (wavelength)
Frequency = (3 x 10⁸ m/s) / (3.2 x 10⁻⁹ m) = <em>9.375 x 10¹⁶ Hz</em>
= 93,750,000 GHz
Answer:
Nuclear Reaction
Explanation:
Technically fusion and fission should be included, but a nuclear reaction includes both fusion and fission, so it must be the answer.
Answer: C
Explanation:
The semi-circular canals are tubular, fluid-filled structures that provide information about head rotations and movements.
The semi-circular canals match the description. Therefore, it is the answer.
Hope this helps!
Answer:
Explanation:
power of a heating element = V² / R where V is voltage and R is resistance
putting in the values
5200 = 75² / R
R = 1.082 ohm
Formula for resistance
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
1.082 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 8.29 m
b )
power of a heating element = V² / R , R is new resistance
5200 = 120² / R
R = 2.77 ohm
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
2.77 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 21.22 m
A. Increase the distance between the effort and the fulcrum
