Answer: Permanent magnets consist of multiple "ferromagnetic materials" I think that might be the answer, there weren't really any choices for me to choose from.
Answer:
(a). The change in the average kinetic energy per atom is 
.
(b). The change in vertical position is 2413 m.
Explanation:
Given that,
Mass = 40.0 u
The increased temperature from 286 K to 362 K.
(a). We need to calculate the change in the average kinetic energy per atom
Using formula of kinetic energy
Put the value into the formula
(b). The change in potential energy of the container due to change in the vertical position
We need to calculate the change in vertical position
Using formula of potential energy
Hence, (a). The change in the average kinetic energy per atom is .
(b). The change in vertical position is 2413 m.
It will spread faster in the hot water! It would spread slower in cold water
Answer:
Acceleration
Explanation:
Acceleration has units of length per time squared.
When the driver is not wearing a seat belt and the car hits a brick wall,
the driver keeps going and doesn't stop, (because of the inertia of the
driver's body).
-- If the driver is lucky, the car is going slow enough, AND it has a
driver-side airbag, AND the airbag works, AND it inflates fast enough,
AND it cushions the driver well enough to avoid the driver's death.
-- If an airbag doesn't stop the driver, then one or more of these brings
the driver to a stop:
... the car's engine block crashing in through the dashboard
... the steering wheel
... the windshield
... the same brick wall that stopped the car.
Any one of these is probably fatal.
