A food handler cannot identify if food has been contaminated with pathogens by its smell, look and taste. The best way to ensure food is pathogen-free is to follow safe food handler’s practices.
Answer:
<em> 30720 oscillation.</em>
Explanation:
Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.
<em>From the question,</em>
<em>The frequency of the string set is 512 Hz,</em>
<em>These means that the spring set complete 512 oscillation in one seconds</em>
<em>I.e</em>
<em>if its completes in one seconds 512 oscillation.</em>
<em>Then, in one minutes, it will complete x oscillation.</em>
<em>x = 512×1min/1seconds</em>
<em>But 1 minutes = 60 seconds</em>
<em>x = 512×60/1</em>
<em>x = 30720 oscillation.</em>

The electrostatic force acting on a charge q is given by
where E is the electric field's intensity.
In our problem, the particle is an electron, so its charge is
. We know the intensity of the force, so we can find the magnitude of the electric field at the point where the electron is located:
where the negative sign means that the force and the electric field have opposite direction, because the charge is negative.
Answer:
14.1seconds approx
Explanation:
Given data
Distance= 59.1m
Your velocity= 2.35m/s
Walkway velocity= 1.85m/s
Total velocity= 2.35+1.85= 4.2m/s
We know that
Velocity= distance/time
time= distance/velocity
substitute
time= 59.1/4.2
time= 14.07
time=14.1seconds approx
Hence the time is 14.1seconds approx
