Answer:
The vector equation of the line is

Parametric equations for given line are

Explanation:
The vector equation of the line is given by

r₀ = (7, -8, 3)
v = (1, 6, -13)
At these points the vector equation for this line is:

Parametric equations for given line are

Answer:
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
Explanation:
Answer: When an ambulance passes with its siren blaring, you hear the pitch of the siren change: as it approaches, the siren’s pitch sounds higher than when it is moving away from you. This change is a common physical demonstration of the Doppler effect.
Explanation:
The particle is an electron. The field slows down the electron without deflecting it. The direction of the electric field is <u>right.</u>
In physics, the motion of electrically charged particles gives rise to a field called an electric field. It is measured in force per unit charge.
This field applies force on other charged particles.
Particles bearing opposite charges attract each other while particles having similar charges repel each other in the field.
If a positive charge is placed in the field then the field line moves in an outward direction and for a negative charge, the direction of the lines is inward.

When you know both the speed and direction of an object’s motion, you know the velocity of an object. speed in a given direction is called velocity
hope this helps :)
