A 23.9 g sample of iridium is heated to 89.7 oC, and then dropped into 20.0 g of water in a coffee-cup calorimeter. The temperat
Nikolay [14]

Answer:

The specific heat capacity of iridium = 0.130 J/g°C

Explanation:

Assuming no heat losses to the environment and to the calorimeter,

Heat lost by the iridium sample = Heat gained by water

Heat lost by the iridium sample = mC ΔT

m = mass of iridium = 23.9 g

C = specific heat capacity of the iridium = ?

ΔT = change in temperature of the iridium = 89.7 - 22.6 = 67.1°C

Heat lost by the iridium sample = (23.9)(C)(67.1) = (1603.69 C) J

Heat gained by water = mC ΔT

m = mass of water = 20.0 g

C = 4.18 J/g°C

ΔT = 22.6 - 20.1 = 2.5°C

Heat gained by water = 20 × 4.18 × 2.5 = 209 J

Heat lost by the iridium sample = Heat gained by water

1603.69C = 209

C = (209/1603.69) = 0.130 J/g°C

a charge of 7.2x10^-5C is placed in an Electric field with a strength of 4.8x10^5N/C. if the Electric potential energy of the ch
Alecsey [184]

Answer:

d= 2.2 m

Explanation:

The data given in the question is

Charge : q =7.2 \times 10^{-5} C

Electric field Strength : E = 4.8 \times 10^{5} N/C

Electrical potential Energy : U = 75J

Let, the distance be "d"

So, the formula for Electrical potential energy is

U= q \times E \times d

Simplified formula for distance become

d=\frac{U}{q \times E}

Now , insert the value

d=\frac{75 J}{7.2 \times 10^{-5}C \times 4.8 \times 10^5 N/C}

or,

d=2.17 m

Rounding off

d= 2.2 m
