but isn't Q already 6000J/h? i am looking for temperature which is T.. so should i rearrange fore T= Q/mc ?
Q= heat or energy absorbed (J) = 6000J/h
m= mass (kg) = 0.965kg
c= specific heat capacity(J/(kg°C) ) = for copper: 3.8 x 10^2 and for glass: 8.4 x 10^2
right?
Homework Statement
Two pitchers of lemonade are left sitting in the sun at a picnic. One pitcher is made of copper and the other of glass. If each empty pitcher has a mass of 965 g and absorbs 1.0 x 10^3 J of energy 10.0 minutes, calculate the temperature increase of both empty pitchers in...
okay so using the first equation for part a) I would have to rearrange it in order to find v2?
meaning...
v1 = 0 m/s (which makes sense)
Δt= 12s or 5s (12s, which is the time for the acceleration or 5s, which is the time for the constant velocity)
Δd= .. i am not even sure
and i DID mean the...
Homework Statement
An object starts at rest and accelerates at 2.5 m/s^2 for 12 seconds. It then moves at a constant velocity for 5.0 seconds and then slows down uniformly at 1.5 m/s^2 until it stops. Calculate:
a) the constant velocity
b) the time taken for deceleration
c) the total...
