Answer:
D = 8 cm
Explanation:
It is given that, the caterpillar walks 18 cm to the left, then 6 cm to the right, then 10 cm to the left.
We need to find the displacement of the caterpillar. The attached figure shows the path traveled by the caterpillar. A is the initial position, then it reaches B and finally it reaches C.
Let right side is positive and left is negative. We know that,
Displacement = final position - initial position
= C - A
= -10-(-18)
= 8 cm
Hence, the displacement of the caterpillar is 8 cm.
Answer:
Temperature, T = 3.62 kelvin
Explanation:
It is given that,
Total number of gas molecules,
Her body is converting chemical energy into thermal energy at a rate of 125 W, P = 125 W
Time taken, t = 6 min = 360 s
Energy of a gas molecules is given by :
, k is Boltzmann constant
T = 3.62 K
So, the temperature increases by 3.62 kelvin. Hence, this is the required solution.
