Initial velocity = Vo= 25 m/s
Final velocity = V = x
Acceleration= a = 6 m/s^2
time= t = 4 seconds
Appy the equation:
V = Vo + at
Replacing:
V = 25 + 6(4) = 25 + 24 = 49 m/s
South it is the same direction the car is already moving
In order to create a charged object you need to transfer electrons either away or to the object by induction, conduction, or friction
Induction is without contact(like bringing a charged object to a electroscope charges the leaves at the bottom)
Conduction is with contact(like the previous answer, wore touching transfers the charge from a source to the object)
Friction(rubbing a balloon on wool)
Answer:
717 Hz
Explanation:
<u>solution:</u>
The wave with three antinodes has m = 3. Thus, f_3 = 3f_1 and so the fundamental frequency of the string is
f_1 =f_3/3
=430 Hz/3
=143 Hz
Thus, the frequency of the fifth harmonic is
f_5 = 5*f_1
= 5*143 Hz
= 717 Hz
