which of the following is the true statement ? a. the magnetic force is perpendicular to the magnetic field direction. b. the magnetic force is parallel to the magnetic field direction. c. the magnetic force is antiparallel to the magnetic field direction. d. none of these

Answers

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.

Final answer:

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.

Explanation:

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.

True or false. The light bulbs in an office building give off tremendous amounts of heat. Since heat is a form of energy, this heat could be trapped and used to offset our need for electricity, thus saving energy and money.

Answers

It is true that the light bulbs in an office building give off tremendous amounts of heat. This heat can be trapped and used to offset our need for electricity.

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

. If the centripetal and thus frictional force between the tires and the roadbed of a car moving in a circularpath were reduced, what would happen?

Answers

In this particular case, where car is moving through curvature, so it is moving in circular motion, force acting on car is centripetal force which holds car not to fly out. Centripetal force is always pointed in the middle of circle. Here frictional force has role of centripetal force. If frictional force is to weak, car would fly out of curvutare.

We spend our lives in visible light without risks to our health. Yet exposure to UV waves in sunlight can cause skin cancer. What is the BEST explanation for this?A) UV waves are longer and carry more energy.
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.

Answers

The correct answer is
B) UV waves are higher frequency and carry more energy.

In fact, UV waves have higher frequency than visible light. For comparison, visible light has frequency in the range 430-770 THz ( $10^(12) Hz$ ), while ultraviolets (UV) have frequency higher than these values (at the order of 1 PHz, $1\cdot 10^(15)Hz$ ).

The energy of electromagnetic radiation is proportional to its frequency, according to the equation
$E=hf$
where h is the Planck constant and f is the frequency. We see that the higher the frequency, the greater the energy, so UV waves carry more energy than visible light.

UV waves are higher frequency and carry more energycausing exposure to UV waves in sunlight to skin cancer. This is a type ofelectromagnetic radiation similar to the waves of the radio, infrared, x-raysand gamma. All of which comes from the sun however cannot be seen by a humaneye. People use these rays for tanning however if it is overdone, it may causeskin problems.
