<h3>
What is amplitude of a pendulum?</h3>
The amplitude of a pendulum is the maximum displacement of the pendulum.
If the maximum displacement of the pendulum is 25 cm, the mass in one period travels a distance less that 25 cm.
Thus, then the mass in one period travels 'a distance<u> less than 25 cm </u>which will be 0.

Answer:
A) True, B) False, C) False and D) false
Explanation:
Let's solve the problem using the law of conservation of energy to know if the statements are true or false
Let's look for mechanical energy
Initial
Emo = Ke = ½ k Dx2
Final
Em1= ½ m v12
Emo = Em1
½ k Δx2 = ½ m v₁²
v₁² = k / m Δx²
v₁ = √ k/m Δx
Now let's calculate the speed when it falls
Vfy² = Voy² - 2gy
Vfy² = - 2gy
Vf² = v₁² + vfy²
A) True v₁ = A Δx
.B) False. As there is no rubbing the mechanical energy conserves
.C) False the velocity is proportional to the square root of the height
v2y = v2 √2
. D) false promotional compression speed
Answer:
0.859375c
31.03 seconds
Explanation:
v' = Velocity of my ship = 0.4 c
u = Velocity of rocket = 0.7 c
c = Speed of light = 
s = Distance between my ship and enemy ship = 
Relativistic addition of speed is given by
The speed of the missile is 0.859375c
Time is given by
It will take 31.03 seconds to reach me.
The answer is the third one down. New evidence may contradict the old evidence of a certain theory.
A peak = A Rms x Sq root 2
Therefore 3.6 x sq root of 2
A peak = 5.09
