Answer:
The final velocity of 18 kg ball is 
= 42.09 
Explanation:
Mass of first ball 
= 18 kg
Mass of second ball 
= 47 kg
Initial velocity of 18 kg ball 
= 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
= 
Put all the values in above formula we get
= 2 × 18 × 
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09
Answer:
Microwave spectroscopy is the spectroscopy method that employs microwaves, i.e. electromagnetic radiation at GHz frequencies, for the study of matter
Density = (mass) / (volume)
Density = (20 g) / (5 cm³)
<em>Density = 4 g/cm³</em> .
The density of the substance is greater than the density of water. A lump of the substance <em>will sink in water</em>, <u>unless</u> the lump is formed into a shape that displaces 20 cm³ of water or more, such as a tiny boat shape.
The distance from the center of mass is as shown in the image:
<h3>What is the center of mass?</h3>
- The center of mass, sometimes referred to as the balancing point in physics, is the only location where the weighted relative position of the distributed mass accumulates to zero.
- Here is where a force can be applied to produce a linear acceleration without also producing an angular acceleration. When calculations in mechanics are made about the center of mass, they are frequently made simpler. It is a fictitious location where one can suppose that an object's full mass is concentrated to see its motion.
- In other words, to apply Newton's equations of motion, the center of mass is the particle equivalent of the provided item.
