The unit for wave frequency is Hertz (Hz)
Answer:
a)
b)
Explanation:
From the exercise we know initial velocity, initial height
º
a) The range of the stone is defined by how far does it goes. From the theory of <u><em>free falling objects</em></u>, we have:
The stone strike the water at y=0
Solving for t, using the quadratic formula
or
Since time can't be negative, the answer is t=3.06s
Now, we can calculate the <u>range of the stone</u>
b) We can calculate the <u>velocity</u> were the stone strike the water using the following formula
The negative sign indicates that the stone is going down
Answer:
1.364 m
Explanation:
We are given that
Frequency,f=110 MHz=
We have to find the distance between the nodal planes of the magnetic field.
We know that
Wavelength,
Where c=
Using the formula
Distance between nodal planes of the magnetic field
Answer:
The evaporation of water is an example of a change in Pysical Change .
The two ends (the ends of the north and south poles) are the most powerful parts of the magnet. They have the strongest magnetic force. As you go down the magnet (closer to the center) the magnet loses its magnetism strength.
