What is the action force and the reaction force you sit down on a chair

2 answers:

7 0

Action force is your weight pushing down on the chair. The reaction force is the force exerted by the chair that pushes up on your body and is equal to your weight. objects have inertia.

Answer:

Explanation: By sitting down on a chair, we apply weight( w = mg) on the chair so our body weight is the action force. As we know by newton's third law of motion chair will also apply an opposite force equal to our body weight on us. This opposite force applied by chair on us is the reaction force.

Answer:

Depends on how long the string is, how heavy the weight, and how high you let go of it.

Two adjacent natural frequencies of an organ pipe are AMT determined to be 550 Hz and 650 Hz. Calculate (a) the M fundamental fr

allochka39001 [22]

Answer:

The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.

Explanation:

Given that,

Frequency f = 550 Hz

Frequency f' = 650 Hz

We know that,

AMT pipe is open pipe.

(b). We need to calculate the length of the pipe

Using formula of organ pipe

$f=\dfrac{nv}{2L}$

For 550 Hz,

$550=\dfrac{n\times340}{2L}$ ...(I)

For 650 Hz,

$650=\dfrac{(n+1)\times340}{2L}$ ...(II)

From equation (I) and (II)

$550-650=\dfrac{340}{2L}-\dfrac{340}{L}$

$L=\dfrac{340}{2\times100}$

$L=1.7\ m$

(a). We need to calculate the fundamental frequency for n = 1

Using formula of fundamental frequency

$=f=\dfrac{n\lambda}{2L}$

put the value of L

$f=\dfrac{1\times340}{2\times1.7}$

$f=100\ Hz$

Hence, The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.

The geologic force applied to rocks is called

amid [387]

The geologic force applied to rocks is called compression. Compression is the stress that squeezes rocks together. As a result of the compression rocks fold or fracture depending on their compressive strength or compression strength - the capacity of a material or structure to withstand loads tending to reduce size.
When the compression is horizontal the crust will be shortened and thickened. When the compression is vertical maximum a section of rock will fail in normal faults, horizontally extending and vertically thinning a given layer of rock.

A car travels 60 miles in the first 2 hours and 68 miles in the next 2 hours

Gemiola [76]

32miles/hr

Explanation:

Given parameters:

Distance 1 = 60miles

Time 1 = 2hrs

Distance 2 = 68miles

Time 2 = 2hrs

Unknown:

Average speed of the car = ?

Solution:

Average speed is the total distance covered in a particular duration of time.

Average speed = $\frac{total distance}{total time taken}$

Total time taken = time 1 + time 2 = 2hrs + 2hrs = 4hrs

Total distance = distance 1 + distance 2 = 60miles + 68miles = 128miles

Average speed = $\frac{128miles}{4hrs}$ = 32miles/hr
