Mike enters a revolving door that is not moving. Mike should
push at the edge of the door where it is largest distance from the pivot point
in order to produce a torque with the least amount of force. Torque is equal to
t = force x distance.
Answer:
doubles
Explanation:
The relationship between angular speed and linear speed in case of a circular motion is the following:
where
v is the linear speed
is the angular speed
r is the distance from the centre of the circular path
In this proble, the pet hamster moves to a point twice as far from the center; this means that its distance from the centre, r', is doubled:
While the angular speed remains the same. Therefore, the new linear speed is
So, the correct answer is
the linear speed doubles
Answer:
-40°C and -273°C ok do it
Answer and explanation;
In 1670 Gabriel Mouton, Vicar of St. Paul’s Church and an astronomer proposed the swing length of a pendulum with a frequency of one beat per second as the unit of length.
In 1791 the Commission of the French Academy of Sciences proposed the name meter to the unit of length. It would equal one tens-millionth of the distance from the North Pole to the equator along the meridian through Paris.It is realistically represented by the distance between two marks on an iron bar kept in Paris.
In 1889 the 1st General Conference on Weights and Measures define the meter as the distance between two lines on a standard bar that made of an alloy of 90%platinum with 10%iridium.
In 1960 the meter was redefined as 1650763.73 wavelengths of orange-red light, in a vacuum, produced by burning the element krypton (Kr-86).
In 1984 the Geneva Conference on Weights and Measures has defined the meter as the distance light travels, in a vacuum, in 1299792458⁄ seconds with time measured by a cesium-133 atomic clock which emits pulses of radiation at very rapid, regular intervals.
B the more kinetic energy an object's particles have the lower the objects temperature is
