Answer:
1.67 A
Explanation:
Given that,
→ Power (P) = 400 W
→ Potential difference (V) = 240 V
→ Current (I) = ?
The amount of current drawn will be,
→ P = V × I
→ I = P/V
→ I = 400/240
→ I = 1.66666666667
→ [ I = 1.67 A ]
Hence, the current drawn 1.67 A.
Explanation:
The coefficient would be carbon since carbon has 2 molecules in h2o and oxygen.
Answer:
Explanation:
Resistivity and resistance are proportional and depends of the length and the cross-sectional area of the wire:
furthermore, the density is the mass divided by the volume, and the volume can be written as the area multiplyed by the length:
Now you have tw equations and two variables, so you can solve for each of them.
first, solve for A in both equations and replace them:
now replace this into any of the previous equiations:
If you assume the wire has circular cross-sectional area, then the area is:
solving for d:
replacing A and simplifying:

Explanation:
Answer:
Amplitude
Explanation:
The amount of energy a wave carries is determined by the amplitude. The larger the amplitude, the more energy the wave has, and the smaller the amplitude, the less energy the wave has.
In this case, since wave A has more energy than wave B, wave B must have a smaller amplitude than wave A.
