Is it possible to code the impact force using an accelerometer?
Naddika [18.5K]

Yes, it possible to code the impact force using an accelerometer.

Accelerometers can be used to measure vibration on cars, machines, buildings, process control systems and safety installations

<h3>What is an Accelerometer ?</h3>

An accelerometer is a device that measures the vibration, or acceleration of motion of a structure.

  • The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.

  • They can also be used to measure seismic activity, inclination, machine vibration, dynamic distance and speed with or without the influence of gravity.

Pepe and Alfredo are resting on an offshore raft after a swim. They estimate that 3.0 m separates a trough and an adjacent crest
Agata [3.3K]

Answer:

The velocity (v) of the wave is 3.08 ms^{-1}.

Explanation:

According to the figure, the distance (\large{L}) between a trough and its adjacent crest is \large{L = 3 m}. Also the wavelength (\large{\lambda}) of the wave is \large{\lambda = 2L}. Pepe and Alfredo count 11 crests to pass the raft in \large{t} = 21.5 s.

So, the time period (\large{T}) of oscillation of the wave is

\large{T} = \dfrac{t}{11} = \dfrac{21.5}{11} = 1.95s

So, the velocity (\large{V}) of the wave is

\large{V = \dfrac{\lambda}{T} = \dfrac{2 \times L}{T} = \dfrac{2 \times 3}{1.95}= 3.08 ms^{-1}}

The robot HooRU is lost in space, floating around aimlessly, and radiates heat into the depths of the cosmos at the rate of 13.1
ahrayia [7]

Answer:

The temperature is  T  = 168.44 \ K

Explanation:

From the question ewe are told that

   The rate of heat transferred is    P  = 13.1 \ W

     The surface area is  A = 1.55 \ m^2

      The emissivity of its surface is  e = 0.287

Generally, the rate of heat transfer is mathematically represented as

           H  =  A e \sigma  T^{4}

=>         T  =  \sqrt[4]{\frac{P}{e* \sigma } }

where  \sigma is the Boltzmann constant with value  \sigma  = 5.67*10^{-8} \ W\cdot  m^{-2} \cdot  K^{-4}.

substituting value  

             T  =  \sqrt[4]{\frac{13.1}{ 0.287* 5.67 *10^{-8} } }

            T  = 168.44 \ K
