Answer:

Explanation:

Given

Free fall acceleration on mars g_{m}=3.7\ m/s^2

Time Period of pendulum on earth T=1\ s

Time period of Pendulum is given by

T=2\pi \sqrt{\frac{L}{g}}

for earth

1=2\pi\cdot \sqrt{\frac{L}{9.8}}

L=\frac{9.8}{(2\pi )^2}

L=0.498\ m

(b)For same time period on mars length is given by

L'=\frac{g_m}{(2\pi )^2}

L'=\frac{3.7}{39.48}

L'=0.0936\ m

L'=9.36\ cm

Some good estimates about the human body can be made if it is assumed that we are made mostly of water. The mass of a water mole
Bezzdna [24]

Answer:

Explanation:

Given

mass of water molecule m=2.99\times 10^{-26}\ kg

mass of person M=62\ kg

It is given that body is mostly made up of water

suppose n water molecules constitutes 62 kg

so n\times m=M

n=\frac{62}{2.99\times 10^{-26}}

n=20.73\times 10^{26}\ kg
