A small metal bar, whose initial temperature was 10° C, is dropped into a large container of boiling water. How long will it tak
IgorC [24]

Answer

According to newton law of cooling

\dfrac{d T}{dt} = k (T - T_a)

and

T = Ce^{kt} + T_a

now At Ta = 100

T₀ = 10 °C

T₁ = 12° C

T(0) = Ce^{0} + T_a

10 = C + 100

C = -90

now,

12 = -90e^k + 100

e^k = \dfrac{88}{90}

k = ln{\dfrac{88}{90}}

at time equal to t

T(t) = 70

T(t) = -90 (\dfrac{88}{90})^t + 100

70 = -90(\dfrac{88}{90})^t + 100

(\dfrac{88}{90})^t = \dfrac{1}{3}

t\times ln(\dfrac{88}{90}) = ln(\dfrac{1}{3})

t = 48.88 s

hence, after 48.88 s the temperature of the body will be 70°C

b) time taken to reach 98°C

T(t) = -90 (\dfrac{88}{90})^t + 100

98 = -90(\dfrac{88}{90})^t + 100

(\dfrac{88}{90})^t = \dfrac{1}{45}

t\times ln(\dfrac{88}{90}) = ln(\dfrac{1}{45})

t = 390 s

hence, after 390 s the temperature of the body will be 98°C

Jasmine rides her bike 9 miles in 50 minutes. what is jasmines speed per hour
Firdavs [7]

<u>Given</u>:

Given that Jasmine rides her bike 9 miles in 50 minutes.

We need to determine the speed per hour.

<u>Time per hour:</u>

The time taken is 50 minutes. We need to convert minutes into hours.

Thus, we have;

\frac{50}{60}=\frac{5}{6} \ hr

Thus, the time taken to cover 9 miles is \frac{5}{6} h r

<u>Speed:</u>

The speed can be determined using the formula,

Speed =\frac{Distance}{Time}

Substituting the values, we have;

Speed =\frac{9}{(\frac{5}{6})}

Simplifying, we get;

Speed =9 \times {\frac{6}{5}}

Speed =\frac{54}{5}

Speed = 10.8

Thus, Jasmine's speed is 10.8 miles per hour.

Calculate 7.30•1.63 and round to the correct number of significant digits
diamong [38]
7.30×1.63=11.899
You only need 2 significant numbers because 7.30 only has 2, the 0 past the decimal without a number doesn't count.
The answer is 12
