R = 11 ohms
Explanation:
Given parameters:
Power of the electric toaster = 1100W
Voltage = 110V
Unknown:
Resistance, R of the heating coli = ?
Solution:
Electric power is given as:
Electric power = IV
where:
I is the current
V is the voltage
According to Ohm's law, V = IR
where R is the resistance. If we make current the subject of the formula and substitute, it gives:
Power = ![\frac{[tex]V^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5DV%5E%7B2%7D)
}{R}[/tex]
Power = ![\frac{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5D110%5E%7B2%7D)
}{R}[/tex]
R = ![\frac{Power }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7BPower%20%7D%7B%5Btex%5D110%5E%7B2%7D)
}[/tex] = ![\frac{1100 }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%20%7D%7B%5Btex%5D110%5E%7B2%7D)

R = 11 ohms

B. solid
Explanation:
The solid state of matter is made up of particles that build repeating patterns. Solid is one of the four physical states of matter.
- Matter is described as anything that has weight and occupies space.
- The four states of matter are solid, liquid, gas and plasma.
- Solid particles are known to be closely packed and held together by very strong attractive forces.
- Solid like sodium chloride are said to be crystalline because they have crystals.
- Crystals are ordered atomic structures formed by repeating units of the fundamental molecular units.
- The repeating patterns of the crystals builds to form a solid.
- Other states of matter do not posses the repeating crystalline structure of solids.

Answer:
Final velocity will be 7.31 m/sec
Explanation:
We have given applied force F = 150 N
Mass of the object m = 11 KG
Distance traveled by the object s = 2.5 m
Coefficient of kinetic friction 
Acceleration due to gravity 
So frictional force applied on the object 
So net force = 150-32.34 = 117.66 N
As work done us equal to 
So work done = 
Now according to work energy theorem work done is equal to change in kinetic energy
So 
v =7.31 m/sec
So velocity final velocity will be 7.31 m/sec
It really all depends weather the temperature
B. my town is powered by electricity that is generated by the energy from the flow of water through a large dam.
The water from the large dam is example of renewable energy. It can be replenished through rainfall cycle, so it is a renewable form of energy.
