Answer:
D. Dissolve
Explanation:
A light wave is not a soluble substance, so it cannot dissolve. But it can totally do A, B, and C.
The answer to this question is the red painted curb. The red painted curb means that the vehicle is not suppose to stop and park in the red curb. It also means that people should not stand in that area. Red painted curb also marks as a fire lane for schools.
The power delivered to the coil is 0.5 Watts
<h3>Resistivity of a material</h3>
The formula for calculating the power delivered to it is expressed according to the equation
Power = I²R
where
I is the current
R is the resistance
Given
Current = 0.500A
Determine the resistance using the resistivity formula
R = ρL/A
Substitute the given parameters
R = 10^-6*(25)/0.002²
R = 2ohms
Substitute
Power = I²R
Power = (0.5)²(2)
Power = 0.5watts
Hence the power delivered to the coil is 0.5 Watts

Electron as a free particle
Explanation:
Free electrons,the electrons which are not attached to the nucleus of a atom and free to move
Answer:
i) No, the spring scale does not read a different value
ii) The torque will read a different value, it will reduce
iii) The spring scale does not need to be measured at the center of mass location.
Explanation:
The torque caused by the gyroscope can be given by the relation,
r × f

The torque measured by the gyroscope varies directly with the distance, r.
A decrease in the distance r will also cause a decrease in the value of the torque measured. When the distance, r is reduced from 7.5 inches to 5 inches, the torque caused by the gyroscope's weight also reduces.
The weight of the gyroscope remains constant despite the reduction in the distance because the weight of the gyroscope is not a function of the distance from the gyroscope. Therefore, the spring scale will not read a different value.
Yes, the spring scale does not need to be measured from the center of mass location because the weight does not depend on the location of measurement. The reading of the sprig scale remains constant.
