Answer: 3.125 ft
Explanation:
If this dish has the form of a concave upward parabola and its vertex 
is at the origin, its corresponding equation is:
Where:
is the radius, which can be found by dividing the diameter 
by half. Hence 
is the depth
is the vertex of the parabola, where its base is
Finding :
Finally:
This is where the the receiver should be placed
The waves that are related to both electricity and magnetism are known as (EM) waves .electromagnetic Waves' this line is about a different topic than the rest of Shondra’s notes.
<h3 /><h3>What is an electromagnetic wave?</h3>
The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves. These waves are made up of time-varying electric and magnetic fields that travel over space.
These waves, which are related to electricity and magnetism, would undoubtedly spread in space. The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves.
These waves are made up of time-varying electric and magnetic fields that travel over space. These waves, which are related to electricity and magnetism, would undoubtedly spread in space.
Hence option 1 is right because the 'Electromagnetic Waves' these line is about a different topic than the rest of Shondra’s notes.

Answer:
980 kJ
Explanation:
Work = change in energy
W = mgh
W = (1000 kg/m³ × 5.0 m³) (9.8 m/s²) (20 m)
W = 980,000 J
W = 980 kJ
The pump does 980 kJ of work.
Answer:
the area of the rectangular field is 10.5 m²
Explanation:
Given;
length of the rectangular field, L = 42 cm = 0.42 m
breadth of the rectangular field, b = 25 m
The area of the rectangular field is calculated as follows;
Area = Length x breadth
Area = 0.42 m x 25 m
Area = 10.5 m²
Therefore, the area of the rectangular field is 10.5 m²
