Answer:
<em>Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip</em>
Explanation:
<u>Proportions and Ratios</u>
To compare two quantities we can perform them some 'test' operations like subtraction or division. If we subtract the first quantity from the second quantity, the difference can be positive if the second is greater, negative if the first is greater, or zero if they are equal.
A similar situation comes if we divide the last by the first. If the ratio (division) is greater than one, then the last quantity is greater than the first if it's less than one, the first is greater, and if it's exactly one, they are equal.
Zoe caught 9 catfish and 6 trout on her first day. It produces a ratio of 9/6=1.5 catfish to trout relation. The second day she caught 17 catfish and 13 trout, which gives us a ratio of 17/13=1.3 catfish to trout.
Based on the ratios we can say Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip
Answer:
A psychoanalyst would see the 4-year-old as having an unresolved conflict where the brain judges or evaluates how good or bad the darkness is, or the usefulness of sleeping in the dark at night based on a comparison, due to the child's exploration of the world around him. A psychoanalyst might see the child's refusal to sleep at night due to the dark as a fear created for instance when the child sleeps alone without the parent. This might change if the child sleeps at night beside the parent in the dark.
While behaviorists would look at how having previous negative experiences in the dark influences a child's behavior towards staying in the dark. This fear would be reinforced with more negative experiences in the dark such as having a bad nightmare whenever the child sleeps in the dark, a feeling of hearing, or seeing strange things while in the dark. These examples would have built a behavioral pattern where the child would be conditioned to respond fearfully to being in the dark.

Answer:
Explanation:
Given that,.
A house hold power consumption is
475 KWh
Gas used is
135 thermal gas for month
Given that, 1 thermal = 29.3 KWh
Then,
135 thermal = 135 × 29.3 = 3955.5 KWh
So, total power used is
P = 475 + 3955.5
P =4430.5 KWh
Since 1 hr = 3600 seconds
So, the energy consumed for 1hr is
1KW = 1000W
P = energy / time
Energy = Power × time
E = 4430.5 KWhr × 1000W / KW × 3600s / hr
E = 1.595 × 10^10 J
So, using Albert Einstein relativity equation
E = mc²
m = E / c²
c is speed of light = 3 × 10^8 m/s
m = 1.595 × 10^10 / (3 × 10^8)²
m = 1.77 × 10^-7 kg
Then,
1 kg = 10^6 mg
m = 1.77 × 10^-7 kg × 10^6 mg / kg
m = 0.177mg
m ≈ 0.18 mg
