Answer:
B. Gravitational force
Explanation:
The gravitational force of an object (also called weight) is given by

where m is the mass of the object and g is the acceleration of gravity, and it always points in the downward direction.
In this problem, the arrow labelled with 4 is the only force pointing downward: therefore, it must be the gravitational force.
The other arrows represent:
1 --> component of the gravitational force parallel to the plane
2 --> force of friction
3 --> component of the gravitational force perpendicular to the plane
Answer:
No
Explanation:
Because if you only measure it by its mass, or weight there could be other substances with the same mass, or weight. If you wanna identify it then list the color, and streak
A car traveling south is 200 kilometers from its starting point after 2 hours. What is the average velocity of the car?
Choose: 100 kilometers/hour south
The body for which its
(Mass) / (radius squared)
is the greatest.
The static frictional force is greater than the kinetic frictional force, so the static frictional force is greater than 1200 N.
