Direction is the length of a route between two points

1 answer:

7 0

The SI unit for distance is the meter (m). Direction is just as important as distance in describing motion. A vector is a quantity that has both size and direction

Hope this helps have a great day!!

ANSWER 5 AND 8!!!!!;$$4$;$;

DedPeter [7]

Answer:

5 ) The mass, 6) with lubrication and using surfaces that are not rough

Explanation:

5) If two bodies are held regardless of their densities and can be combined by some chemical or physical process, the only physical property to be modified will be the mass of the resulting body.

Friction depends on the contact between two surfaces and when a body has a relative motion with respect to a contact surface. In order to reduce friction the contact surface must be lubricated, also the friction depends on the coefficient of friction between surfaces and the normal force exerted by the surface parallel to the area of contact with the body. Mathematically it can be expressed with the following equation.

$F_{f} = u*N\\where:\\u = friction coefficient\\N = normal force [Newtons]\\F_{f}= friction force [Newtons]$

Energy that is the sum of potential and kinetic energy is

Pani-rosa [81]

Answer:

The correct answer would be B.

Explanation:

I believe the answer is B because for electrical energy you would need electric charges to be moved by kinetic energy.

Can the magnitude of a vector ever (a) be equal to one of its components, or (b) be less than one of its components? 9. Can a pa

Ber [7]

Answer:

a) the other components are zero, in the direction of one of the coordinate axes

b) the magnitude is less than the value of one of its components, it must occur when the vector is in some arbitrary direction

9) constant velocity the acceleration must necessarily be zero,

constant speed can be accelerated since it may be changing the direction of the velocity vector

Explanation:

Vectors are quantities that have modulo (scalar) direction and sense.

a) If in a vector its magnitude is equal to one d its components implies that the other components are zero, therefore the vector must be in the direction of one of the coordinate axes

b) if the magnitude is less than the value of one of its components, it must occur when the vector is in some arbitrary direction, other than the direction of the axes, that is

R² = x² + y²

where R is the magnitude of the vector e x, and are the components

9) When a particle has a constant velocity, the acceleration must necessarily be zero,

v = vo + a t

The bold letters indicate vectors If a = 0 implies that v = vo

If a particle has constant speed it can be accelerated since it may be changing the direction of the velocity vector, this type of acceleration has the name of centripetal acceleration

Two electrically opposite charges are separated by a fixed distance. Which action will provide the greatest increase in the forc

Alex73 [517]

Explanation:

The electric force between charges is given by the formula as follows :

$F=\dfrac{kq_1q_2}{r^2}$

k is electrostatic constant

r is distance between charges

Here, charges are equal and opposite. So,

$F=\dfrac{kq^2}{r^2}$

It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :

Increasing the magnitude of charges
Decreasing the distance between charges.
