A neutron has zero charge but their mass is <span>1.67492716 × 10^-27 kg </span>
In a solution, the movement of electric charge is given by the movement of ions (positive or negative), which are the result of dissociation of molecules of the solution.
In solid objects, instead, the movement of electric charge is given by the movement of valence electrons or by holes, created when a valence electron leaves a vacancy in the outer shell of an atom.
Air resistance is a force that slows down objects moving through the air. ... Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent. An object with more surface area will have more air resistance.
Answer:
B) T > ma.
Explanation:
To solve this problem, we have to analyze the forces acting in the horizontal direction.
In the horizontal direction, we have:
- The horizontal component of the tension in the wire, , where T is the magnitude of the tension and the angle that the wire makes with the horizontal
Since this is the only force acting on the box in the horizontal direction, this is also the net force, so it is equal to the product of mass and acceleration (Newton's second law of motion):
where
m is the mass of the box
a is the acceleration
We can rewrite the equation as
The angle in this problem is , so
Therefore, the correct option is
B) T > ma.
S- sexually T- transmitted D- disease
These are usually transmitted by some sort of sexual inter-coarse .
some examples of STD's are HIV,chlamydia,genital herpes,&gonorrhea . These are not the only ones there are many other types of STDs
