Night hunting animals have more rod cells in their retinas which allows them to see better in the dark.
Answer:
a) -35.6°C
b) 237.4 K
Explanation:
To convert temperature from degree celsius to degree fahrenheit, use the formula below:
a) Therefore to convert -32°F to celsius, substitute it into the celsius
b) To covert to the Kelvin scale, use the formula below
so as this ant moves
5 cm every second you multiply 5 by 120 (60 per minute as there are 60 seconds in a minute)
this is 600 cm
or
6 meters
A: a person sitting on a train
Hence person could have a meal and not get food all over them.
Answer:
4. B and D
Explanation:
Two points along a transverse wave (such as the one in the figure) are said to be in phase when:
- the vertical position of the two points is the same
- The oscillation of the wave is going in the same way for both points
Basically, we say that two points are in phase when they are separated by a complete cycle (one complete oscillation) of the wave.
For this wave, we see that point B and C have same displacement, but they are not in phase since in B the oscillation is going down while in C is going up.
Instead, B and D are in phase, because they are separated by one complete cycle: both points have same displacement and the oscillation is going in the same way for both of them.
