<u>Answer:</u> The speed of the dog is 8 ft/s

<u>Explanation:</u>

Speed is defined as the ratio of distance traveled to the time taken.

To calculate the distance traveled by boat, we use the equation:

\text{Speed of the dog}=\frac{\text{Distance traveled}}{\text{Time taken}}

We are given:

Distance traveled by dog = 40 ft

Time taken = 5 seconds

Putting values in above equation, we get:

\text{Speed of the dog}=\frac{40ft}{5s}\\\\\text{Speed of the dog}=8ft/s

Hence, the speed of the dog is 8 ft/s

Find what is the ratio of the internal energy of hydrogen UB. To the internal energy of helium UJ for two moles of hydrogen and
finlep [7]

Answer:

Ration of internal energy of hydrogen to the internal energy of helium is equal to \frac{5}{6}

Explanation:

As we know

degree of freedom of hydrogen is 5

Degree of freedom of helium is 3

Internal energy of hydrogen

\frac{5}{2} * 2 * RT = 5 *RT

Internal energy of helium

\frac{3}{2} * 4 * RT = 6 *RT

Ration of internal energy of hydrogen to the internal energy of helium is equal to \frac{5}{6}

A 1400.0 kg car crests a 3200.0 m pass in the mountains and briefly comes to rest. The car descends 1000 m before climbing and c
rjkz [21]

Answer:

a) v = 88.54 m/s

b) vf = 26.4 m/s

Explanation:

Given that;

m = 1400.0 kg

a)

by using the energy conservation

loss in potential energy is equal to gain in kinetic energy

mg × ( 3200-2800) = 1/2 ×m×v²

so

1400 × 9.8 × 400 = 0.5 × 1400 × v²

5488000 = 700v²

v² = 5488000 / 700

v² = 7840

v = √7840

v = 88.54 m/s

b)

Work done by all forces is equal to change in KE

W_gravity + W_non - conservative = 1/2×m×(vf² - vi²)

we substitute

1400 × 9.8 × ( 3200-2800) - (5 × 10⁶) = 1/2 × 1400 × (vf²  -0 )

488000 = 700 vf²

vf² = 488000 / 700

vf² = 697.1428

vf = √697.1428

vf = 26.4 m/s
