Answer:
A, magnetic force is always perpendicular to the magnetic field. The direction of the magnetic force is perpendicular to both the direction of the velocity and the direction of the magnetic field.
The magnetic force is always perpendicular to the direction of the magnetic field, according to the Right-Hand Rule in Physics. Neither parallel nor antiparallel statements are correct.
The correct answer to your question, in regard to the relationship between magnetic force and magnetic field direction, is option A. According to the Right-Hand Rule in Physics, the magnetic force exerted on a moving charged particle is always perpendicular to the direction of the magnetic field. This means the force and field are not parallel or antiparallel to each other, but rather, they meet at a 90-degree angle.

Answer: True
Explanation: A sonographer can adjust the duration of an acoustic pulse because it depends on the pulse's propagation speed.
Answer:
FALSE
Explanation:
The light bulbs in an office building give off tremendous amounts of heat. Heat is a form of energy, but this heat could not be trapped as heat is a dynamic energy which can not be stored but this energy can flow from high temperature to low temperature.
So here when heat is generated then it will flow towards the region of low temperature and by the time it will convert into several other forms.
So here above statement is NOT correct.
FALSE
B) UV waves are higher frequency and carry more energy.
C) UV waves have a lower frequency and carry more energy.
D) UV waves travel faster than visible light and have more energy.
