"The number of waves per second will increase" is the statement among the choices given in the question that <span>will be true if you increase the frequency of a periodic wave. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has helped you.</span>
Answer:
<h2>39.15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 14.5 × 2.7
We have the final answer as
<h3>39.15 N</h3>
Hope this helps you
Explanation:
Let us assume that the question says,"In a shower connected in summer and winter positions, with the following characteristics: 220V - 2200W / 4400W. Calculate the electric current that circulates at the lowest (summer) and highest (winter) power, with the same voltage. Tip: isolate the electric current in the expression P = Ix V
"
It is given that,
In a shower connected in summer and winter positions, with the following characteristics: 220 V - 2200 W / 4400 W.
It means lowest power is 2200 W and highest power is 4400 W
For lowest power,
I = electric current for summer
For highest power,
I' = electric current for winters
