Answer:

the instrument that gives this precision is the micrometer screw

Explanation:

The high precision measurements of small parts are the general vernier and the micrometer screw.

In these two instruments the same principle is used: there is a fixed rule and a mobile one that increases precision.

Let's analyze the absolute error or precision of each instrument

* For the vernier, the precision of the fixed rule is 1 mm and there are 20 divisions (the most common); therefore the precision of the instrument is

            Δx = 1 mm / 20

            Δx = 0.05 mm

* For the micrometer screw, the precision of the fida rule is 0.5 mm and the number of divisions is 50, therefore the precision of the screw is

            Δx = 0.5mm / 50

            Δx = 0.01 mm

consequently the instrument that gives this precision is the micrometer screw

To be safe, the engineers making the ride want to be sure the normal force does not exceed 1.5 times each persons weight - and t
ANTONII [103]

Answer:

The minimum coefficient of friction is 0.666

Explanation:

Suppose, In a classic carnival ride, patrons stand against the wall in a cylindrical shaped room. Once the room gets spinning fast enough, the floor drops from the bottom of the room! Friction between the walls of the room and the people on the ride make them the “stick” to the wall so they do not slide down. In one ride, the radius of the cylindrical room is R = 7.6 m and the room spins with a frequency of 20.9 revolutions per minute.

Given that,

The normal force does not exceed 1.5 times each persons weight

N=1.5 mg

We need to calculate the minimum coefficient of friction

Using balance equation

\mu N=mg

\mu=\dfrac{mg}{N}

Where, N = normal force

Put the value into the formula

\mu=\dfrac{mg}{1.5 mg}

\mu=\dfrac{1}{1.5}

\mu=0.666

Hence, The minimum coefficient of friction is 0.666

A 100 V battery is connected across a
Sergio039 [100]

1 mA = 0.001 A

Therefore, 5 mA = 0.001 * 5

=0.005 A

Resistance = voltage / current

= 100 / 0.005

= 20000 ohms

Current = voltage / resistance

= 25 / 20000

= 0.00125 A (or) 1.25 mA

What does the word apparent mean in apparent visual magnitude
SSSSS [86.1K]

The word 'apparent' mean in apparent visual magnitude is, how bright the star appears when viewed from Earth.

What is visual magnitude?

The brightness of a celestial body is determined by eye estimation with or without optical aid or by other instrumentation equivalent to the eye in spectral sensitivity.

Apparent magnitude:

  • Apparent magnitude is a measure of how bright the star appears when viewed from Earth.
  • It is a measure of the brightness of a star or other astronomical object observed from Earth.
  • An object's apparent magnitude depends on its intrinsic luminosity and its distance from Earth.

Hence,

The word 'apparent' mean in apparent visual magnitude is, how bright the star appears when viewed from Earth.

A race car makes one lap around a track of radius 180 m in 90.0 s. What is the centripetal acceleration in m/s2?
kvasek [131]

Answer:

0.9m/s^2 (yours is 0.87, so choose that)

Explanation:

formula for centripetal acceleration:

v^2/r

to find v, we know that f=1/90s, and r=180m.

v=(2pir)/T

v=(2pi(180))/90

v=12.6m/s

now plug into a=v^2/r

a=(12.6)^2/180

a=0.9m/s^2
