<h3>Characteristics: </h3><h3>the length of the stem, battery savers, varied choices on how to clean it thoroughly, the battery replacements, a good sensitivity to heat, and precise readings are the basics that classify thermometers as good-working. </h3>
Answer:
Option (D)
Explanation:
Reflection is the phenomenon in which a ray of light strikes on a smooth and polished surface and then bounce back into the same medium at same angle.
There are two types of reflection.
1. Regular reflection or specular reflection
2. Irregular reflection or diffused reflection
When a parallel beam of light falls on a smooth and highly polished surface and after reflection the rays are also parallel to each other, it is called regular reflection.
When after parallel beam of light falls on a rough surface and after reflection the rays of light goes in random directions, it is called diffused reflection.
The rays reflected at 90 degree to - 90 degree in diffused refectory.
Answer:
curves downward, below the initial velocity vector.
Explanation:
Projectile launches are generally divided into two types: the oblique throw and the free fall. The free fall of bodies consists of throwing or abandoning projectiles from a hill or any unevenness that has a height in relation to a frame (usually the ground), while the oblique launch consists of launching a projectile at an angle. any relative to a frame (usually the ground).
Regardless of the type, when reading the paragraph above, we can say that the trajectory of a projectile will always be curved down and below the initial velocity vector.
Objects in contact with each other never get past the electron clouds of the atoms on their surfaces.
Force can alter its direction,slow or stop it you could say it can change its velocity
