Answer:
0.5A
Explanation:
V=IR where V is 1.5V, R is 3 ohms
Hence 1. 5= I x 3
1.5/3 =I
I =0.5 A
Current is 0. 5 amperes
Answer: The color of a star plays a significant role in determining its age as well as its temperature. A star normally appears to be shining as we see through the atmosphere. An increase in the temperature of a star releases more energy and this can be observed in the various colors of color spectrum.
The hottest star generally appears to be bluish-white in color whereas the coldest star usually appears to be reddish in color.
Thus, a star's color can help us determining its temperature.
Answer:
B. decreases while his angular speed remains unchanged.
Explanation:
His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
