It rises till all of its Kinetic energy is converted into potential energy.
so, mgh=(1/2)m(v^2)
so, h=(v^2)/2g = 12*12/(2*9.81)=7.34 m
Answer:
Explanation:
Heat gained by ice in warming up to 0⁰C = .035 x 2090 x (83-0)= 6071.45 J
heat used up by ice to melt at 0⁰C = .035 x 3.33 x 10⁵ J = 11655 J
Heat used up in warming up water to t⁰C = .035 x 4186 x t = 146.51 t
heat released by warm water to cool from 22⁰C to t = .565 x 4186 x ( 22 - t )
=52032 -2365.1 t
heat released by copper calorimeter to cool from 22⁰C to t = .087 x 387 x ( 22 - t ) = 740.72 - 33.7 t
total heat released = 52032 -2365.1 t + 740.72 - 33.7 t
= 52772.72 - 2398.8 t
Heat lost = heat gained
52772.72 J- 2398.8 t = 6071.45 J + 11655 J + 146.51 t
2545.31 t = 35046.27
t = 13.8°C.
Velocity =2 pie*r/t
distance = 2 (pie) r
accelaretion =distance/t2
f=m*v2/r
v=square root of Fr/m
Answer:
They will repel each other since they have the same charge specifically negative
