The amplitude of the pendulum is 5cm.
Amplitude is the maximum displacement of the wave from its mean position upwards or downwards.
As the graph of the motion of pendulum swings from +5cm to -5cm for each cycle, the magnitude of peak amplitude of the pendulum is 5 centimeters.

annihilate each other?
(1) 1.64 × 10^–13 J (3) 5.47 × 10^–22 J
(2) 8.20 × 10^–14 J (4) 2.73 × 10^–22 J
Answer:
(1)
Explanation:
Energy released in this process is given by
here we have
since here mass of two electrons converted into energy so we have
so here energy released is the energy of rest mass energy due to two charges i.e. electrons and positrons
The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is 1.64 x 10⁻¹³ J.
The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is calculated as follows;
E = Δmc²
where;
E = (2 x 9.11 x 10⁻³¹) x (3 x 10⁸)²
E = 1.64 x 10⁻¹³ J

b. Find the ball’s range from question 2.
Answer:
2.57 s
8.12 m
46.4 m
Explanation:
1. In the y direction:
s = 0 m
u = 22 sin 35° m/s = 12.6 m/s
a = -9.8 m/s²
Find: t
s = ut + ½ at²
0 = (12.6) t + ½ (-9.8) t²
t = 2.57 s
2. In the y direction:
u = 12.6 m/s
v = 0 m/s
a = -9.8 m/s²
Find: s
v² = u² + 2as
0² = (12.6)² + 2 (-9.8) s
s = 8.12 m
3. In the x direction:
u = 22 cos 35° m/s = 18.0 m/s
a = 0 m/s²
t = 2.57 s
Find: s
s = ut + ½ at²
s = (18.0) (2.57) + ½ (0) (2.57)²
s = 46.4 m
Current - APEX :) lol it said my answer wasn't long enough so yeah Hi
