(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

Answer:
We experience interference while listening to the radio. A radio station works by sending and receiving radio waves. Since the radio waves are being interfered with other waves which must have a wave nature.
The interference is the net result of two individual waves. It can be constructive or destructive interference and is the property of waves and not particles.
This interference is an example of electromagnetic radiation. Thus we experience wave behavior of electromagnetic radiation in our daily communications.
Answer:280.33 m
Explanation:
Given
motorcycle starts from rest
initial acceleration
distance traveled =120 m
velocity gain during this time, let say v
after it starts decelerating with 1.5 m/s^2 [/tex]
final velocity()=12 m/s
12=25+(-1.5)t
t=8.667 s
distance traveled during this time
Therefore total displacement=
