Explanation:
- We know that Newton's second law of motion gives the measure of external force acting on an object. It says that the rate of change of linear momentum of an object is directly proportional to the external applied force. It is given by :
Since, p = mv m is mass and v is velocity.
So, if one knows only the constant resultant force acting on an object and the time during which this force acts, one can determine the change in momentum of the impulse.
<h2>
Answer </h2>
The answer to this question is <u>407.5 g</u>
<h2>
Explanation</h2>
- The density of the substance = 1.63 g/ml
- The volum of the substance = 0.25 L
- Mass of the substance = ? (Determined)
We know that
So, 0.25 L will be equal to 250 ml. ( Unit must be same)
Formula
Se, mass of the substance is 407.5 g
Answer:
Density is the relationship between mass and volume.
D = M / V
The atomic mass of an atom ... in Atomic Mass Units ... is the sum of the numbers of protons and neutrons in its nucleus.
