GalinKa [24]

Answer:

how large a magnetic field would you experience = 8.16 x 10∧-4T

Explanation:

I = 20KA = 20,000A

r = 4.9 m

how large a magnetic field would you experience =  u.I/2πr

how large a magnetic field would you experience = (4π x10∧-7) × 20000/2π × 4.9

how large a magnetic field would you experience = 8.16 x 10∧-4T

Svetllana [295]

Answer:

The final temperature is 64.28°C.

Explanation:

Imagine now that one tried to repeat the same measurement, but between the time that the 400 cm³ of warm water was measured at 88°C and the time it was mixed with the 130 cm³ of cooler water at 15°C, the warmer water had lost 3060 cal to the environment. Calculate the final equilibrium temperature assuming no heat loss after mixing occurs.

Let the temperature of hot water before mixing is t

We need to calculate the temperature

Using formula of energy

Q=mc\Delta t

Q=V\times\rho\times c\times(T_{2}-T_{1})

Put the value into the formula

3060=400\times1\times1\times(88-t)

3060=400\times88-400t

-t=\dfrac{3060-400\times88}{400}

t=80.35^{\circ}

We need to calculate the final temperature

Using formula of temperature

T_{f}=\dfrac{V_{w}T_{w}+V_{c}T_{c}}{V_{w}+V_{c}}

Put the value into the formula

T_{f}=\dfrac{400\times80.3+130\times15}{400+130}

T_{f}=64.28^{\circ}C

Hence, The final temperature is 64.28°C.
