Answer:
Watts=Volt*Amps
So A=570/120=4.75amps
If voltage drops to 110V We get A=570/110=5.(18...)amps

Answer:
C: You must know force and distance to calculate both.
Explanation:
A force is said to have done work, when it has succeeded in causing displacement in an object from its starting point.
Power can be defined as the rate of doing work. 
The work can be calculated using the following formula:
Work done = Force × Displacement 
The power can be calculated using the following formula:
Power = Work \ Time
In order to calculate the work and power, the force and distance should be known. The force and distance will help in the calculating the work, which will in turn help in the calculation of the power of the object.
Hence, the answer is you must know force and distance to calculate both.

Answer:
Explanation:
                     BeSO₄ + 2NH₄OH → Be(OH)₂ + (NH₄)₂SO₄
In a replacement reaction, an atom or ion substitutes or replaces another in a reaction. We can have single replacement or double replacement reaction. 
The above is a double replacement reaction. In this type of reaction, partners are exchanged to form compounds. In a single replacement, one substance is replacing another.
