B or c hopefully it helps
Answer:
Explanation:
mass of car, m = 1000 kg
initial velocity, u = 20 m/s
final velocity, v = 0 m/s
distance, s = 120 m
Let a be the acceleration of motion
use third equation of motion
v² = u² + 2 as
0 = 20 x 20 + 2 x a x 120
a = - 1.67 m/s²
Let F be the force
Force, F mass x acceleration
F = - 1000 x 1.67
F = - 1666.67 N
The direction of force is towards south and the magnitude of force is 1666.67 N.
We don't have much to go on.
The dimensions of D depend on the dimensions of N, n, and x, and we don't know what any of those stand for.
It might help if we had ever heard of 'diffastion', but we're striking out there too.
An object with a constant pushing or pulling force is exerted on it is greater than the frictional force, than A. The object will accelerate.
Answer:
Animal-like protists are those which cannot make their own food. These protists have the ability to move themselves and are often further subdivided into groups based on how they move. Plant-like protists are those that make their own food using sunlight and water. They can live in water or on trees.
