Answer:
B. ceramics
Explanation:
Ceramics are materials which are inorganic and non-metallic materials made from compounds of metals and non metals. They are usually oxides, carbides and nitrides. They are stronger, harder and more resistant to heat than a wide variety of other types of materials. They found a great use in the industry such as for making glass wares, pottery , valves, spark plugs, pressure sensors, vibration sensors,bricks, cement,insulators, resistors, superconductors, capacitors ,ceramic rotors e.t.c.
Answer:
n = 3.26
Explanation:
given,
human need 380 W of power to walking 5 Km/hr
human body 380 J of energy per second for walking 5 Km/h
speed of human 5 x 0.278 = 1.39 m/s
for walking 1.39 m energy required = 380 J
distance traveled in 3 hours of walking
d = 1.39 x 3 x 3600
d = 15012 m
energy needed
![E = \dfrac{380}{1.39}\times 15012](https://tex.z-dn.net/?f=E%20%3D%20%5Cdfrac%7B380%7D%7B1.39%7D%5Ctimes%2015012)
E = 4,104,000 J
now,
one pizza slice give 1260000 J pf energy
slice of pizza
![n = \dfrac{4104000}{1260000}](https://tex.z-dn.net/?f=n%20%3D%20%5Cdfrac%7B4104000%7D%7B1260000%7D)
n = 3.26
