I’m assuming that’s m^3? If so then simply divide 160,000 by 20 and you get the answer.
8,000 kg/m^3
Answer:
17.00 N
Explanation:
Given that the x-component of a vector is 17, and the angle between the vector and the x-axis is 46 degrees
The magnitude of the vector will be calculated by first resolving the vector into x component and y component.
X - component
17cos46 = 11.809
Y component
17sin46 = 12.229
We will find the resultant vector by using pythagorean theorem
R = sqrt ( X^2 + Y^2 )
R = sqrt ( 11.809^2 + 12.229^2 )
R = sqrt ( 288.995 )
R = 16.999
R = 17.00 N
Therefore, the magnitude of the vector is 17 .00N
Larger than one.
In fact, the index of refraction of a medium is the ratio between the speed of light in vacuum (c) and the speed of light in that medium (v):
But the maximum speed the light can travel at is exactly c, the speed of light in vacuum: so v is always less (or equal, in case of vacuum) than c, and so n is always greater than 1.
The BIG Equation. Newton's second law<span> of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.</span>
