Two 84.5 g ice cubes are dropped into 30 g of water in a glass. If the water is initially at a temperature of 50 C and if the ic
Setler [38]

Answer:

final temperature will be 0 degree C

Total amount of ice will be

m_{ice} = 182 g

total amount of water

m_{water} = 17 g

Explanation:

After thermal equilibrium is achieved we can say that

Heat given by water = heat absorbed by ice cubes

so we will have

Heat given by water to reach 0 degree C

Q_1 = m_1s_1 \Delta T_1

Q_1 = 0.030(4186)(50 - 0)

Q_1 = 6279 J

heat absorbed by ice cubes to reach 0 degree

Q_2 = m_2 s_2 \Delta T_2

Q_2 = (0.169)(2100)(30)

Q_2 = 10647 J

so we will have

Q_2 > Q_1

so here we can say that few amount of water will freeze here to balance the heat

10647 - 6279 = mL

m = \frac{10647 - 6279}{335000}

m = 13 g

so final temperature will be 0 degree C

Total amount of ice will be

m_{ice} = 84.5 + 84.5 + 13

m_{ice} = 182 g

total amount of water

m_{water} = 30 - 13

m_{water} = 17 g

A 40 cm wire with a radius of 3 cm is oriented along the y axis and carries a current of 2 A. What is the magnitude of the magne
ZanzabumX [31]

Answer:

a) B = 1.99 x 10⁻⁴ Tesla

b) B = 0.88 x 10⁻⁴ Tesla

Explanation:

According to Biot - Savart Law, the magnetic field due to a currnt carrying straight wire is given as:

B = μ₀ I L/4πr²

where,

μ₀ = permebility of free space = 1.25 x 10⁻⁶ H m⁻¹

I = current = 2 A

L = Length of wire = 40 cm = 0.4 m

a)

r = radius of magnetic field = 2 cm = 0.02 m

Therefore,

B = (1.25 x 10⁻⁶ H m⁻¹)(2 A)(0.4 m)/4π(0.02 m)²

<u>B = 1.99 x 10⁻⁴ Tesla</u>

<u></u>

b)

r = radius of magnetic field = 3 cm = 0.03 m

Therefore,

B = (1.25 x 10⁻⁶ H m⁻¹)(2 A)(0.4 m)/4π(0.03 m)²

<u>B = 0.88 x 10⁻⁴ Tesla</u>
