artic foxes have thick white fur to keep them warm and also for camouflage in the snow they have small ears to keep the snow out of their ears so that they can hear better they also have thick fur lining and a thick pad on their feet this stops the paws from getting cold and they have short legs so then the body weight can be spread making it easier for the animal to not sink in the snow in the summer the artic fox turns brown to help make the fox invisible when people are hunting in the long grass
Answer:
10 V
Explanation:
The potential difference between two points is the amount of work required to carry a unit charge from one point to the other point. This would result in a potential difference between this two points.
The difference between the potential across two points B and A is ![V_{BA}=V_B-V_A](https://tex.z-dn.net/?f=V_%7BBA%7D%3DV_B-V_A)
From the image attached:
![V_B-V_A=10-10I+20\\\\But\ I = 2A,hence:\\\\V_B-V_A=10-10(2)+20\\\\V_B-V_A=10-20+20\\\\V_B-V_A=10\ V](https://tex.z-dn.net/?f=V_B-V_A%3D10-10I%2B20%5C%5C%5C%5CBut%5C%20I%20%3D%202A%2Chence%3A%5C%5C%5C%5CV_B-V_A%3D10-10%282%29%2B20%5C%5C%5C%5CV_B-V_A%3D10-20%2B20%5C%5C%5C%5CV_B-V_A%3D10%5C%20V)
The only thing acting as the roller coaster gets to the bottom is gravity thus
acceleration is 9.81
so u use the formula
vf^2 = vi^2 + 2abetaD
thus
distance = vf^2 - vi^2 divided by 2a
so 26^2 - 0^2 divided by 2(9.81m/s)
equals 676 divided by 2(9.81m/s)
= 34.45463812m
then use the appropriate 3 sig digs
so 34.5m
hopes this helps
