melisa1 [442]

Answer:

H_2 = 91.55 km

Explanation:

Gravity on the surface of planet is given as

g = \frac{GM}{R^2}

as we know that

M = 8.93 \times 10^{22} kg

R = 1821 km

now gravity on the planet is

g = \frac{(6.67 \times 10^{-11})(8.93 \times 10^{22})}{(1821 \times 10^3)^}

so we have

g = 1.8 m/s^2

now we know that

H_{max} = \frac{v^2}{2g}

so we will say

\frac{H_1}{H_2} = \frac{g_2}{g_1}

\frac{500}{H_2} = \frac{9.81}{1.8}

H_2 = 91.55 km

A stone that starts at rest free falls for 7.0 s. How far does the stone fall in this time?
vredina [299]

Gravitational acceleration is approx 9.8 m/s
Time is 7s

a=9.8 m/s
t=7s

a = d/t^2

therefore:

d = a * t^2

d = 9.8 * 7^2

d = 9.8 * 49

d = 480.2 [m]

A ball is dropped from a height of 23.5 meters. Assuming no air resistance, how many seconds will it take the ball to hit the
Alex Ar [27]

Answer:

About 2.19 seconds

Explanation:

d=v_ot+\dfrac{1}{2}at^2

Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:

23.5=\dfrac{1}{2}(9.8)t^2 \\\\t^2\approx 4.79 \\\\t\approx 2.19s

Hope this helps!

sweet [91]

Answer:

Y = 2.27 \times 10^{10} N/m^2

Explanation:

Natural length of the string is given as

L_o = 43 cm

length of the string while block is hanging on it

L = 53 cm

extension in length is given as

\Delta L = 10 cm

now we have strain in the string is given as

strain = \frac{\Delta L}{L}

strain = \frac{{10 cm}{43 cm}

strain = 0.23

similarly we will have cross-sectional area of the string is given as

A = 40 \times 10^{-6} m^2

now the stress in the string is given as

Stress = \frac{T}{A}

Stress = \frac{mg}{A}

Stress = \frac{3.7 \times 9.81}{40 \times 10^{-6}}

stress = 9.07 \times 10^5 N/m^2

Now Young's Modulus is given as

Y = \frac{stress}{strain}

Y = \frac{9.07 \times 10^5}{40\times 10^{-6}}

Y = 2.27 \times 10^{10} N/m^2
