On Earth, the period of a pendulum is given by:
where L is the length of the pendulum and
is the gravitational acceleration on Earth.
Similarly, the period of the same pendulum on Mars will be
where
is the gravitational acceleration on Mars.
Therefore, if we want to see how does the period of the pendulum on Mars change compared to the one on Earth, we can do the ratio between the two of them:
Therefore, the period of the pendulum on Mars will be 1.63 times the period on Earth.

Answer:
The heat flux between the surface of the pond and the surrounding air is<em> 60 W/</em><em> </em>
Explanation:
Heat flux is the rate at which heat energy moves across a surface, it is the heat transferred per unit area of the surface. This can be calculated using the expression in equation 1;
q = Q/A ...............................1
since we are working with the convectional heat transfer coefficient equation 1 become;
q = h () ........................2
where q is the heat flux;
Q is the heat energy that will be transferred;
h is the convectional heat coefficient = 20 W/.K;
is the surface temperature =
C 23°C + 273.15 = 296.15 K;
is the surrounding temperature =
C = 20°C + 273.15 = 293.15 K;
The values are substituted into equation 2;
q = 20 W/.K ( 296.15 K - 293.15 K)
q = 20 W/.K ( 3 K)
q = 60 W/
Therefore the heat flux between the surface of the pond and the surrounding air is 60 W/
