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
Answer: s=d/t=68m/s/12m/s= 5.6 M/s
Explanation:
Answer:
Four basic fources.
Explanation:
Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.
