Answer:
Technician A
Explanation:
1- It's was easy to understand.
2- Holding down a battery could actually cause battery plate damage. Most of the batteries I interact with only use a plastic cover and a small spring to hold the battery in place.

Temperature 
Ambient pressure is 1 atm.
Generally the equation for Density is mathematically given by



Generally the equation for Flow rate is mathematically given by

Where




Therefore


Where



Probably B because I impulsively shop online and b is true for me. I’m not 100% sure though.
Elastic Potential Energy is zero detailed description is given below.
Explanation:
- It is the energy stored in stretched or compressed elastic materials. This also means that elastic potential energy is zero in objects that have not been stretched or compressed.
- To determine the gravitational potential energy of an object, a zero height position must first be arbitrarily assigned. Typically, the ground is considered to be a position of zero height. But this is merely an arbitrarily assigned position that most people agree upon. Since many of our labs are done on tabletops, it is often customary to assign the tabletop to be the zero height position. Again this is merely arbitrary. If the tabletop is the zero position, then the potential energy of an object is based upon its height relative to the tabletop. For example, a pendulum bob swinging to and from above the tabletop has a potential energy that can be measured based on its height above the tabletop. By measuring the mass of the bob and the height of the bob above the tabletop, the potential energy of the bob can be determined.
- Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. An object possesses elastic potential energy if it is at a position on an elastic medium other than the equilibrium position.
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Answer:
Equation of the streamline V = 4i - 4j m/s
Unit Vector n = (4i+4j)/4√2
Explanation:
Parameters
x=2 and y=-1
V=(2x)i + (yt)j m/s
Substituting (x=2) and (y=-1) into the velocity field V
Therefore V = 4i - tj where t=4s
Equation of the streamline
V = 4i - 4j m/s
Unit vector normal to the streamline n
Note V.n=0 and the velocity only have x- and y - components
Therefore
V.n=(4i - 4j).(nₓi+nyj)=0 or 4nₓ - 4ny = 0
The unit vector requires that nₓ^2+ny^2=1
Therefore n = (4i+4j)/4√2
