You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
Answer:

Explanation:
Speed of van, v = 28 m/s
Radius of unbanked curve, r = 150 m
Let
is the angle with the vertical. In case of banking of road,
.............(1)
And
..........(2)
From equation (1) and (2) :



So, the string makes an angle of 28.07 degrees with the vertical. Hence, this is the required solution.
Answer:
455,000 Pa
Explanation:
PV = nRT
If n is constant:
PV / T = PV / T
(101,325 Pa) (718 mL) / (273 K) = P (175 mL) / (26 + 273) K
P = 455,000 Pa
Answer:
they would repel because they have the same charge. Charges that are different will stick together.
Answer:
infrared radiation
Explanation:
infrared radiation - infrared radiation is part of electromagnetic radiation which wavelength range from about 700 nano meters (nm) to 1 millimeter (mm).
Infrared radiation is invisible to naked eye, however it can be felt as heat for longer duration infrared waves. Any type of radiation — whether it is visible light or radio waves — may possibly be hazardous if extremely focused in a high-powered narrow beam
