What is the ﬁnal equilibrium temperature when 12 g of milk at 7◦C is added to 175 g of coﬀee at 69◦C? Assume the speciﬁc heats o

lina2011 [118]

Answer:

ﬁnal equilibrium temperature is 65.02 ◦C

Explanation:

Given data

milk = 12 g

temp milk = 7◦C

coffee = 175 g

coffee temp = 69◦C

to find out

ﬁnal equilibrium temperature

solution

we apply here equilibrium condition i.e m c ΔT

milk mass × c × ΔT = coffee mass × c × ΔT

12 × 1 × (T- 7) = 175 × 1 × ( 69- T)

12T - 84 = 12075 - 175 T

187 T = 12159

T = 65.02

so ﬁnal equilibrium temperature is 65.02 ◦C

The electric field between the plates of a parallel-plate capacitor is horizontal, uniform, and has a magnitude E. Asmall object

kirza4 [7]

Answer:

$m = 0.041 kg$

Explanation:

As we know that the small particle is in equilibrium at an angle of 16 degree with the vertical

so here we can use force balance in vertical and horizontal direction

$T cos\theta = mg$

$T sin\theta = qE$

now from above equation we have

$T = \sqrt{(mg)^2 + (qE)^2}$

also by division of above two equations we have

$\frac{qE}{mg} = tan\theta$

$qE = mg tan\theta$

now from above equation again

$T = \sqrt{(mg)^2 + (mg)^2 tan^2\theta}$

$T = mg sec\theta$

$0.420 = m(9.81) sec 16$

$m = 0.041 kg$
