Answer:
V= A ω maximum KE of object in SHM
V2 / V1 = .958 ratio of amplitudes since ω is constant
KE2 / KE1 = 1/2 m V2^2 / (1/2 m V1^2) = (V2 / V1)^2
KE2 / KE1 = .958^2 = .918
So KE2 = .918 KE1 and .082 = 8.2% of the energy is lost in one cycle
The best technique to separate an insoluble solid from a liquid is filtration. Filtration is a process that separates solids from liquid by adding a medium, such as a filter paper, that only liquid can pass, and what is left behind the filter paper is the insoluble solid.
Answer:
m=43.39 Kg
Explanation:
from conservation principle we have
heat gained by ice equal to heat lost by coffee
heat gained by ice = heat from -15 °C ice to 0 °C ice + 0 °C ice to 0 °C water + 0 °C water to 65 °C water
= m*S1*15 + mL + ms2 *65
where s is specific heat of respective phase
= m(2.08 *15 + 334.16 + 4.184 *65)
= m*637.32
heat lost by the coffee= ms* delta T
=0.3 *4190 *(87-65)
=27654
therefore
27654 = m*637.32
m=43.39 Kg
Answer:

Explanation:
given,
Average velocity due west = 1.20 m/s
case 1
Distance moved in west, x₁ = 5.63 km
speed due west, v₁ = 2.33 m/s
Case 2
Distance moved in east = x₂
speed due east, v₂ = 0.374 m/s
total distance = x₁ + x₂ = 5.62
total time = t₁ + t₂ = 5630/2.33 + x₂/0.374
now,


negative sign is used because we want the distance in east but velocity is in west.



The distance she walked in east is equal to 648.46 m
Answer:Im guessing Mechanical Energy
Explanation:
We are learning that work and energy work hand in hand so im completely guessing this
