True or False. The fulcrum of a first class lever is between the output force and an input force.

Answers

Answer:

True

Explanation:

A first-class lever is a lever in which the fulcrum is located between the input effort and the output load. In operation, a force is applied (by pulling or pushing) to a section of the bar, which causes the lever to swing about the fulcrum, overcoming the resistance force on the opposite side

how could you use Newton's Second Law to study forces?

Answers

Answer:

A police car is moving east at 20m/s towards a driver who is moving west at 25m/s. The police car emits a frequency of 900Hz. What frequency is detected by the driver? The speed of sound at the time of this occurrence was 343m/s.

Answers

Answer:

f = 2445 Hz

Explanation:

i did the quiz

The frequency that the driver (observer) detects is equal to 1008 Hz

Given the following data:

Observer velocity = 25.0 m/sFrequency of sound = 900 HzSource velocity = 20.0 m/s Speed of sound = 343 m/s

To calculate the frequency that the driver (observer) detects, we would apply Doppler's effect of sound waves:

Mathematically, Doppler's effect of sound waves is given by the formula:

[tex]F_o = \frac{V \;+ \;V_o}{V\; - \;V_s} F[/tex]

Where:

V is the speed of a sound wave.F is the actual frequency of sound.[tex]V_o[/tex] is the observer velocity.[tex]V_s[/tex] is the source velocity.[tex]F_o[/tex] is the observer frequency.

Substituting the given parameters into the formula, we have;

[tex]F_o = \frac{343 \;+ \;20}{343\; - \;20} \times 900\\\\F_o = \frac{363}{323} \times 900\\\\F_o = 1.12 \times 900\\\\F_o =1008 \;Hz[/tex]

Driver (observer) frequency = 1008 Hz
