An object moving in the air at a constant speed is considered to be in a balanced state. Explain Why
faust18 [17]

Answer:

and there is no friction

Explanation:

An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity.

A distance of 200 ft must be taped in a manner to ensure a standard deviation smaller than ± 0.04 ft. What must be the standard
Nutka1998 [239]

Answer:

The error in tapping is ±0.02828 ft.

Explanation:

Given that,

Distance = 200 ft

Standard deviation = ±0.04 ft

Length = 100 ft

We need to calculate the number of observation

Using formula of number of observation

n=\dfrac{\text{total distance}}{\text{deviation per tape length}}

Put the value into the formula

n=\dfrac{200}{100}

n=2

We need to calculate the error in tapping

Using formula of error

E_{series}=\pm E\sqrt{n}

E=\dfrac{E_{series}}{\sqrt{n}}

Put the value into the formula

E=\dfrac{0.04}{\sqrt{2}}

E=\pm 0.02828\ ft

Hence, The error in tapping is ±0.02828 ft.
