Answer:
31.831 Hz.
Explanation:
<u>Given:</u>
The vertical displacement of a wave is given in generalized form as
<em>where</em>,
- A = amplitude of the displacement of the wave.
- k = wave number of the wave =
= wavelength of the wave.- x = horizontal displacement of the wave.
= angular frequency of the wave = 
.- f = frequency of the wave.
- t = time at which the displacement is calculated.
On comparing the generalized equation with the given equation of the displacement of the wave, we get,
therefore,
It is the required frequency of the wave.
Answer:
Option (c) is correct.
Explanation:
Acceleration of an object is given by the formula as follows :
Where
u and v are initial and final velocity
t is time
(v-u) is also called the change in velocity
So, the acceleration of an object is equal to the rate of change of velocity. Hence, the correct option is (c) " Change in its velocity divided by the change in time".
<h2>
Hello!</h2>
The answer is 31.67 Amps.
<h2>
Why?</h2>
To solve the problem, we need to use Ohm's Law equation, which states that:
Where,
V, is the voltage (in volts)
I, is the current (in Amps)
R, is the resistance (in Ohms)
We are given the following information:
So, using Ohm's Law equation and substituting the given information, we have:
Hence, we have that the current used by the blender is 31.67Amps.
Have a nice day!
Helium has only 2 electrons in it's valence shell
So, option D is your answer.
Hope this helps!
Answer:
c is correct
Explanation:
There are two equal forces on each sides of the rope. The greater opposing sides pull, the greater the magnitude of tension force along the rope.
