Along with neurons, the nervous system contains other specialized cells called glial cells (or simply glia), which provide structural and metabolic support. Nervous systems are found in most multicellular animals, but vary greatly in complexity.
Answer:
Both Technicians A and Technician B
Explanation:
According to Technician A, the bearings are lubricated by being submerged in gear fluid and it is done to keep bearings temperature low and keep friction low as well.
Technician B point of view is also correct as seals prevent any type of impurity to get inside oil. The feature of the oil seal is to forestall something fluid is inner from leaking out the clearance among the shaft and housing. The seal is also be used to save you outside materials, together with dirt, from shifting in via the clearance.
Answer:
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Explanation:
Watt is a unit for power that is equivalent to Joules per second (J/s). Therefore, to figure out the energy burnt up during an activity, first we need to know how long (in seconds) that activity took.
1- Running
V = 10.0 km/h
d = 5.50 km
t = 5.50/10 = 0.55 h = 0.55(h) *60 (min/h) *60(s/min) = 1,980 s
2- Walking
V = 3.0 km/h
d = 5.50 km
t = 5.50/ = 1.83333 h = 1.83333(h) *60 (min/h) *60(s/min) = 6,600 s
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
The car's final velocity is 11.6 m/s in the opposite direction.
