Use F = 1/T as your basis:

DaniilM [7]

Frequency=60Hz

$\\ \rm\rightarrowtail \nu=\dfrac{1}{T}$

$\\ \rm\rightarrowtail T=\dfrac{1}{\nu}$

$\\ \rm\rightarrowtail T=\dfrac{1}{60}$

$\\ \rm\rightarrowtail T=1.67\times 10^{-4}s$

$\\ \rm\rightarrowtail T=16.7\times 10^{-3}s$

$\\ \rm\rightarrowtail T=16.7ms$

What is initial velocity

Lapatulllka [165]

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.

The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8. What is the ideal efficiency of the engine? Use

vodomira [7]

Answer:

e=58%

Explanation:

Given data

The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8.

Solution

We want to calculate the ideal efficiency of the engine when ratio of heat capacity for gas used γ=1.40. Ideal efficiency (e) of the Otto cycle given by:

$e=1-(\frac{1}{r^{Y-1} } )\\$

Substitute the given values to find efficiency e

$e=1-\frac{1}{8.8^{1.4-1} } \\e=0.58\\$

e=58%
