Answer:
The current needed to transmit Power of 4 W is 28.47 A
Solution:
As per the question:
Length of the antenna,
Frequency,
Power transmitted,
Now,
For a monopole antenna:
where
= wavelength transmitted by the antenna
c = speed of light in vacuum
Now,
Since, the value of >> thus the monopole is a Hertian monopole.
The resistance is calculated as:
Now, the current I is given by:
Answer:
BaF2
Explanation:
since you got the valence numbers just do the scissors move where you:
give the F the 2 and give the Ba the 1 so it be like
BaF2 here is the chemical compound
The government should put it support in a combination of sources, as no
source in the present can fully provide all energy requirements.
Answer:30.34 m
Explanation:
Given
launch angle
Initial velocity u=31.9 m/s
Position of net = 39.1 m
We know equation of trajectory of a projectile is
Therefore Net should be placed 30.34 m above ground
