Amplitude modulation is used in AM radio.
Answer is A.
Value of g on Venus=8.87 m/s²
Period of pendulum=1.75 s
Given pendulum,
T=2π√(L/g)
(1.5)=2π√(L/8.87)
L=0.505 m
A and C because stronger attractions means it needs more energy to break them so a higher temperature is needed
The normal force acting on April as she stands on a flat surface is 705.6 N.
Normal force of the girl
Fₙ = mg
where;
- Fₙ is the normal force of the girl
- m is mass of the girl
- g is acceleration due to gravity
Fₙ = 72 x 9.8
Fₙ = 705.6 N
Thus, the normal force acting on April as she stands on a flat surface is 705.6 N.
