The correct ans is 1.
A changing electric field produces a changing magnetic field which in turn produces a changing electric field. This means that the source has created a changing electric and magnetic fields, perpendicular to each other, that travel away from the source. Electric field, magnetic field and the EM wave are perpendicular to each other. This gives electromagnetic waves their transverse nature.
The work done by the water at the constant pressure is 
.
<h3>Heat required to boil the water</h3>
The heat required to boil the water is calculated as follows;
where;
is the heat of vaporization of water = 22.6 x 10⁵ J/kg- m is mass of water
<h3>Work done by the water</h3>
The work done by the water at the constant pressure is equal to the heat gained by the water.

Answer:
Weight of car = 36034.88 lb.ft/s²
Explanation:
We are told the pressure of the four tires of your car is; P = 35.0 psi
Also, the surface area of contact is; A = 32 in²
Thus;
Weight of tires = Pressure × Area
W_tires = 35 × 32
Weight_tires = 1120lb.
To get the weight of the car, we will multiply the tire weight by acceleration due to gravity.
It's value in ft/s² is g = 32.174 ft/s²
Thus;
Weight of car = 1120 × 32.174
Weight of car = 36034.88 lb.ft/s²
