lubasha [3.4K]

Answer:

Given that

The earth spins on its axis once a day and orbits the sun once a year (365 1/4 days)

a)

When earth spins on its axis

We know that earth take 1 day to complete one revolution around its own axis.

T= 1 day = 24 hr = 24 x 3600 s

T=86400 s

We know that

T=2π/ω

ω= 2π/T

ω= 2π/86400

ω=7.27 x 10⁻5 rad/s

b)

When earth revolve around earth

T =365 1/4 days = 365.25 days

T= 365.24 x 86400 s

T=31557600

We know that

T=2π/ω

ω= 2π/T

ω= 2π/31557600

ω=1.99 x 10⁻⁷ rad/s

PROBLEM 5 (Problem 4-145 in 7th edition) Consider a well-insulated horizontal rigid cylinder that is divided into two compartmen
kari74 [83]

Answer:

The answer is "\bold{83.8^{\circ} \ C}".

Explanation:

Formula for calculating the mass in He:

\to m = \frac{PV}{RT}\\

        = \frac{500 \times 1}{ 2.0769 \times (40 + 273)}\\\\ = \frac{500 }{ 2.0769 \times 313}\\\\ = \frac{500 }{ 650.0697}\\\\= 0.76914 \ Kg

Formula for calculating the mass in N_2:

\to m = \frac{PV}{RT}\\

        = \frac{500 \times 1}{ 0.2968 \times (120+ 273)}\\\\ = \frac{500 }{ 0.2968 \times 393}\\\\ = \frac{500 }{ 116.6424}\\\\= 4.2866\ Kg

by using the temperature balancing the equation:

T' = \frac{mcT (He) + mcT ( N_2 )}{ mc (He) + mc ( N_2)}

    = \frac{0.76914 \times 3.1156 \times 313 + 4.2866 \times 0.743 \times393}{  0.76914 \times 3.1156 + 4.2866 \times 0.743} \\\\ = 357  \ \ K \approx  83.8^{\circ} \ C

At the instant the traffic light turns green, a car that has been waiting at an intersection starts with a constant acceleration
Setler79 [48]

Answer:

(a) 300 ft

(b) 60 ft/s

Explanation:

distance d=0.5at^{2} where a is acceleration and t is time

d=0.5\times 6\times t^{2}=3t^{2}

Also, d=vt where v is the velocity

d=30t

Therefore

30t=3t^{2} hence t=10 s

Substituting t is either formula

d=30t=30*10=300 ft

Also

v=at hence v=6\times 10=60 ft/s
