Answer:
35.7 m
Explanation:
Let


We have to find the distance between Joe's and Karl'e tent.


Substitute the values then we get




Because vertical component of B lie in IV quadrant and y-inIV quadrant is negative.
By triangle addition of vector






Hence, the distance between Joe's and Karl's tent=35.7 m
Answer:
The frequency is the same
Explanation:
When a wave is created by a source which is vibrating at a certain frequency, the frequency of the wave itself is equal to the frequency of the source.
This occurs with every kind of wave. For instance, if we consider the radio waves produced by an antenna, the frequency of the radio waves is equal to the frequency of the antenna.
In this case, the waves are created by the vibrating bug. The bug is vibrating with a certain frequency
: as a consequence, the frequency
of the waves produced by the bug will be equal to the frequency of vibration of the bug:
.
Answer:

Explanation:
We know that charge on electron

r= 2 nm
We know that force between two charge given

Now by putting the value


We know that mass of electron
The mass of electron

F= m a
a= Acceleration of electron
a= F/m


initial velocity given that zero ,u=0

Answer: Surface waves can have characteristics of both longitudinal and transverse waves in the following way; The motion of the surface waves is up and down which is perpendicular to the direction of the wave. This is similar to the motion of transverse waves whereas the the motion of longitudinal.
Explanation:
Answer:
density of the ball is 3.33 g/cc
Explanation:
As we know that the density is the ratio of mass and volume
here we know that
mass = 20 g
volume = 6 cubic cm
so we will have
