Answer

given,

jet plane is traveling = 525 m/s

radius = 5.2 Km

a_c = ?                          

a_c = \dfrac{v^2}{r}          

a_c = \dfrac{525^2}{5200}

a_c = 53 m/s^2                  

we know                                              

g = 9.8 m/s²                                        

\dfrac{a_c}{g}=\dfrac{53}{9.8}

\dfrac{a_c}{g} = 5.41

a_c = 5.41 g

Answer:

Acceleration of the plane, a = 5.4 g

Explanation:

It is given that,

Speed of the jet plane, v = 1890 km/h = 525 m/s

Radius of the arc, r = 5.20 km = 5200 m

The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :

a=\dfrac{v^2}{r}

a=\dfrac{(525\ m/s)^2}{5200\ m}

a=53.004\ m/s^2

We know that, the value of g is, g=9.8\ m/s^2

\dfrac{a}{g}=\dfrac{53.004\ m/s^2}{9.8\ m/s^2}=5.4

a=5.4\times g

So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.

Distance in scientific notation
n200080 [17]

Answer:

(See explanation for further information)

Explanation:

a) The distances of each planet with respect to the Sun is:

Mercury - 57.909 \times 10^{6}\,mi

Venus - 67.240\times 10^{6}\,mi

Earth - 92.960\times 10^{6}\,mi

Mars - 141.600\times 10^{6}\,mi

Jupiter - 483.800\times 10^{6}\,mi

Saturn - 888.200\times 10^{6}\,mi

Uranus - 1,787\times 10^{6}\,mi

Neptune - 2,795\times 10^{6}\,mi

b) The solutions are presented below:

A. The distance between Venus and Jupiter is:

\Delta s = 483.800\times 10^{6}\,mi-67.240\times 10^{6}\,mi

\Delta s = 416.560\times 10^{6}\,mi

B. The combined distance from the Sun is:

\Delta s = 57.909\times 10^{6}\,mi + 67.240\times 10^{6}\,mi +92.960\times 10^{6}\,mi

\Delta s = 218.109\times 10^{6}\,mi

Which is less than the distance from the Sun to Neptune (2,795\times 10^{6}\,mi).

C. The new distance of Earth is 929.60 \times 10^{6}\,mi (929,600,000\,mi). Saturn would be the closest planet to Earth, whose distance:

Scientific notation:

\Delta s = 929.600\times 10^{6}\,mi-888.200\,\times 10^{6}\,mi

\Delta s = 41.4\times 10^{6}\,mi

Standard notation:

\Delta s = 929,600,000\,mi - 888,200,000\,mi

\Delta s = 41,400.000\,mi

If you change the mass of a moving object, you change its _______.
Paul [167]
Momentum and inertia, Momentum=P. P=MV. M=mass and V=velocity. Mass is related to inertia so inertia=F. F=MA. A=acceleration.
