Answer:
To find the density of an object, start by determining the object's mass and volume. Then, divide the mass by the volume to find the object's density. Remember to write your answer in grams per cubic centimeter. If your answer is long, you can round it down to 2 or 3 digits past the decimal place!
Explanation:
Answer:
The difference in the phase angle between any two waves at any given position along the waves.
Explanation:
Phase difference describes the difference in the phase angle between any two waves at any given position along the waves. The equation of wave is given by :
Wave 1,
Wave 2,
Where
A is the amplitude of wave
is the angular frequency
is the phase difference between two waves
If is the path difference, it is given by :
Hence, the correct option is (a) "the difference in the phase angle between any two waves at any given position along the waves".
The answer was that Copernicus objected to Ptolemaic system where the theory states that the universe is geocentric, where celestial bodies moves around the earth instead of the solar system model where it was patterned to Copernicus' model where science have accepted that the sun is indeed the center of our solar system and not true with Ptolemy's argument.
(a) The acceleration of the two block is determined as 0.93 m/s².
(b) The tension in the string is 5.78 N.
<h3>Net force on the aluminum block</h3>
The net force on the aluminum block is calculated as follows;
<h3>Net force on the copper block</h3>
The net force on the copper block is calculated as follows;
where;
- T is tension in the string
- ma is mass of aluminum
- mc is mass of copper
- g is acceleration due to gravity
Solve for T using (1) and (2)
<h3>Tension in the string</h3>
From equation (1);
T = μm_ag + m_aa
T = 0.2(2)(9.8) + 2(0.93)
T = 5.78 N
