Answer:
ΔT=3.781 Kelvin
Explanation:
Given data
m=5.00g 0r 0.005kg
v=44.0 m/s
c (specific heat)=128 j/kg
Kinetic Energy=![\frac{1}{2}mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D)
KE=![\frac{1}{2}(0.005)(44)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%280.005%29%2844%29%5E%7B2%7D)
KE=4.84 joules
1/2 Kinetic energy goes to heat=1/2×4.84
=2.42 J
Q=mcΔT
ΔT=
ΔT=![\frac{2.42}{0.005*128}](https://tex.z-dn.net/?f=%5Cfrac%7B2.42%7D%7B0.005%2A128%7D)
ΔT=3.781 K
The correct option is D.
Micheal Friday devised a wire which hanged down into a glass vessel that has a bar magnet secured at the bottom. He then filled the glass vessel with Mercury and connected the apparatus to a battery. This sent electricity through the wire, thus creating a magnetic field around it. This field interacted with the field around the magnet and cause the wire to rotate clock wisely.
Answer:
condensing
Explanation:
Condensing is the word used to indicate the change of state of a substance from vapor to liquid, as in this case. During condensation, the substance releases thermal energy to the environment, therefore the kinetic energy of the molecules in the vapor decreases until they become closer to each other and they start to be affected by the intermolecular forces and so the substance becomes a liquid.
