The speed of the water in the wider part will be 1.194 m/sec. Speed is a time-based quantity. Its SI unit is m/sec.
<h3> What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained.
The given data in the problem is;
The initial diameter is,
initial radius,
The initial crossection area;
The final crossection area;
The initial flow rate is;
R = density ×velocity ×area
The speed of the water in the wider part will be;
From the continuity equation;
Hence, the speed of the water in the wider part will be 1.194 m/sec.

It must have a medium. It must travel in empty space. Mechanical waves are waves which needs medium of propogation.
Answer:
0 J
Explanation:
Work is the product of force and distance in the direction of force.
The formula is ; Work = Force * Distance
Given that :
Force = 400 N
Distance = 0 meters
Work = 400 * 0 = 0 J
No work was done because the boulder did not move.
Answer: The first one
Explanation: I think it's the first one because it says what is the "least" gravitational potential energy story between the prairie dog and Earth that said resting in its borrow is using less energy
Some metals having unpaired electrons contain a strong magnetic response, i.e, they can be magnetized by an external magnetic field.
