Answer:

3.77 Hz

Explanation:

The beat frequency that is heard can be calculated using the following equation:

$f_{b} = f_{1} - f_{2}$

Where:

f₁ = 110 Hz

$f_{2} = \frac{f_{1}}{\sqrt{\frac{T_{1}}{T_{2}}}}$

With:

T₁ = 594 N

T₂ = 554 N

$f_{2} = \frac{f_{1}}{\sqrt{\frac{T_{1}}{T_{2}}}} = \frac{110 Hz}{\sqrt{\frac{594 N}{554 N}}} = 106.23 Hz$

Hence, the beat frequency is:

$f_{b} = f_{1} - f_{2} = 110 Hz - 106.23 Hz = 3.77 Hz$

Therefore, the beat frequency that is heard when the hammer strikes the two strings simultaneously is 3.77 Hz.

I hope it helps you!

The displacement is 2 m south

Explanation:

Distance and displacement are two different quantities:

Distance is the total length of the path covered by an object during its motion, regardless of the direction. It is a scalar quantity
Displacement is a vector connecting the initial position to the final position of motion of an object. The magnitude of the displacement is the distance in a straight line between the two points

For the car in this problem, the motion is:

10 m south

8 m north

Taking north as positive direction, we can describe the two parts of the motion as

$d_1 = -10 m$
