Aharmonic oscillator is described by the function x(t) = (0.210 m) cos(0.220t). find the oscillator's maximum velocity and maximum acceleration. find the oscillator's position, velocity, and acceleration when t = 2.50 s. note that it asks for answers in m/s not rad/s(a) oscillator's maximum velocity (in m/s)(b) oscillator's maximum acceleration (m/s2)(c) oscillator's position (in m) when t = 2.50 s(d) oscillator's velocity (in m/s) when t = 2.50 s(e) oscillator's acceleration (in m/s2) when t = 2.50 s

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
