The ramp with the smallest or greatest mechanical advantage is the steepest.
1 answer:
The ramp with the smallest mechanical advantage is the steepest.
In fact, the ideal mechanical advantage of a ramp is given by the ratio between the length L of the ramp and its height h:
The steepest ramp is the ramp with largest height h, therefore it is the ramp with the smallest mechanical advantage, because its ratio L/h is the smallest.

Answer:
The possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
Explanation:
Given that,
The notes produced by a tuba range in frequency from approximately 45 Hz to 375 Hz.
The speed of sound in air is 343 m/s.
To find,
The wavelength range for the corresponding frequency.
Solution,
The speed of sound is given by the following relation as :
Wavelength for f = 45 Hz is,
Wavelength for f = 375 Hz is,
So, the possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
Answer:
The jet will fly 2400 km.
Explanation:
Given the velocity of the jet flying toward the east is 1,500 kmph toward the east.
We need to find the distance covered in 1.6 hours.
In our problem we are given speed and time, we can easily determine the distance using the following formula.
So, the supersonic jet will travel 2400 km in 1.6 hours toward the east from its starting point.
