The answer is B. High Pitch Sound
Answer:
The value of charge is 35.3 C
Explanation:
Given:
Force 
N
Electric field 
According coulomb's law,
Where 
charge that experience a force,
For finding the value of charge,
C
Therefore, the value of charge is 35.3 C
The answer is B. The obvious questions do not always lead to interesting results. This is because if everyone did the same thing every time, we wouldn't find any new data. With variables, we have so many different options, leading to creativity and new data found!
Answer:
A. Ahmed has a greater tangential speed than Jacques.
D. Jacques and Ahmed have the same angular speed.
Explanation:
Kinematics of the merry-go-round
The tangential speed of the merry-go-round is calculated using the following formula:
v = ω*R
Where:
v is the tangential speed in meters/second (m/s)
ω is the angular speed in radians/second (rad/s)
R is the angular speed in meters (m)
Data
dA = RA : Ahmed distance to the axis of rotation
dJ = RJ : Jacques distance to the axis of rotation
Problem development
We apply the formula (1)
v = ω*R
vA= ω*RA : Ahmed tangential speed
vJ= ω*RJ : Jacques tangential speed
Ahmed is at a greater distance from the axis of rotation than Jacques, then,
RA ˃ RJ and Ahmed and Jacques have the same speed ω, then:
vA ˃ vJ
