n = number of vibrations set in the string = 400 vibrations
t = total time taken for "n" vibrations set in the string = 4 second
f = frequency of the sound emitted due to vibrations set in the string
frequency of the sound emitted due to vibrations set in the string is given as
f = n/t
inserting the above values in the above formula
f = 400/4
f = 100 Hz
hence the frequency of sound comes out to be 100 Hz

Answer:
The current through the circuit element will also be doubled.
Explanation:
The relationship between voltage and current of a circuit element is given by Ohm's Law. According to Ohm's Law:
Voltage = (Resistance)(Current)
If the resistance of the element is kept constant, the relation between Voltage and Current through that element becomes as follows:
Voltage = (Constant)(Current)
Voltage α Current
Thus, the voltage is directly proportional to the current for constant value of the resistance.
Therefore, when the voltage across a circuit element of constant resistance is doubled, <u>the current through the circuit element will also be doubled.</u>
Answer: 100 miles per hour
Today, tubular steel tracks and polyurethane wheels allow coasters to travel over 100 miles per hour (160 km/h), while even taller, faster, and more complex roller coasters continue to be built. Hopefully i helped
