The correct answer to the question is : B) A moving charge has both an electric and magnetic field, and a stationary charge has only an electric field.
EXPLANATION :
Before answering this question, first we have to understand the nature of field created by charge particles.
If the charge particle is at rest i.e stationary, then the field created by the charge particle is electric in nature. Hence, a stationary charge particle produces electric field only.
If a charge particle moves with uniform velocity, then the field will be only magnetic .Hence, a non accelerating charge particle will produce magnetic field.
If a charge particle accelerates, then the field created by the charge particle is electromagnetic in nature.
Hence, the correct answer of this question is the second statement.
B. orange
C. red
D. violet
The longest wavelength within the visible spectrum is red light. The correct option is C.
The visible spectrum of light consists of different colors ranging from red to violet. Each color corresponds to a different wavelength. Among the given options, red light has the longest wavelength within the visible spectrum.
A. blue: Blue light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum.
B. orange: Orange light has a shorter wavelength compared to red light. It falls between red and yellow on the visible spectrum.
C. red: Red light has the longest wavelength among the visible colors. It is located on the longer end of the visible spectrum.
D. violet: Violet light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum, just after blue.
Therefore, the correct option is C. red as it has the longest wavelength within the visible spectrum.

6001 pounds is slightly more than 3 tons. This is because, in the comparison scale, 1 ton is equal to 2000 pounds. So, 3 tons equals 6000 pounds.
The student is asking which is more, 3 tons or 6001 pounds. To determine this, we need to understand the relationship between tons and pounds. We know that 1 ton is equivalent to 2000 pounds. So, 3 tons would be equivalent to 3*2000 = 6000 pounds.
Hence, comparing 6001 pounds with 3 tons, or effectively 6000 pounds, 6001 pounds is slightly more than 3 tons.

a. True
b. False
False, just because it's not physical, doesn't mean it's any less harmful than emotional.
