Answer: a. net force is acting on object A in the same direction of its motion.
Explanation:
The second law of Newton states that the acceleration of a particular object is dependent on two main things which are the mass and force. According to the law, the acceleration of the object will be directly related to the net force while the acceleration is also relates inversely to the mass.
Therefore, based on the information given in the question, a force is acting on object A in the same direction of its motion.
Answer:
E
Explanation:
There is not enough information in the question. A beat is the observed differences between two frequencies.
Hence, 3 beat represents a difference of 3-hertz between the two frequencies. So the frequency of the piano string could be 1056+3 = 1059-hertz or 1056-3= 1053-hertz.
In order to ascertain the actual value i.e if it is an increase or a decrease in frequency observed, we need more information.
Answer:
<em>The magnetic field's direction is towards the north</em>
<em></em>
Explanation:
The force on a positive charge in a uniform magnetic field is represented by the right hand rule. To determine the direction of the force, place your right hand with your palm up, and your thumb at 90° to the other fingers. If the fingers represent the magnetic field, and the thumb the direction of the positive charge, then the palm will push up in the direction of the force. But a negative charge like an electron pushes in exactly the opposite direction. So if you follow this rule, you will find that the magnetic field points towards the north.
Sex cells have half as many chromosomes as other cells. Sex cells are therefore called haploid.
