Answer: Separately derived system
Explanation: A separately derived system is used to describe a premise wiring system whose power is derived from a source of electrical energy such as transformer, solar photovoltaic cell or generator. A separately derived system has no direct connection to any conductor from another system or doesn't generate it's power from any direct connection to a conductor from another system or source except those from established from bonding or grounding connections. Separately derived systems usually generate it's power on it's own.
Answer:
70 m/s.
Explanation:
because the vertical velocity component of 30 m/s was initial horizontal velocity of 40 m/s was maximum height.
The principle of operation of a pressurized garden sprayer is as follows;
A pressurized garden sprayer is a chamber which is filled with a liquid which can be a lubricant, paint or chemical, then filled with compressed air to allow the liquid to be sprayed at high pressure.
As it is pumped by hand, the compressed air with which it is filled serves the primary purpose of allowing the liquid to be sprayed at high pressure - an important requirement for performance characteristics of the sprayer.
Flammable liquids must not be used with such equipment.

Answer: liquid to solid
Explanation: Kinetic energy is the energy possessed by an object by virtue of its motion.
Solid is the phase of matter where particles have strongest inter molecular forces and thus molecules posses no kinetic energy.
Liquid is the phase of matter where kinetic energy of the molecules is almost equal to the inter molecular forces.
Gas is the phase of matter where kinetic energy of the molecules is more than the inter molecular forces present among molecules and hence the molecules move randomly.
Thus the phase change is from liquid to solid.
