The weight of an object is given by

where m is the mass of the object, while g is the strength of the gravity (which corresponds to the gravitational acceleration of the planet).
In our problem, the shoes have a mass of m=0.5 kg, and their weight is F=11.55 N. So, we can re-arrange the previous formula to find the value of g:

and this is the strength of the gravity on Jupiter's surface.
Answer:
The complete question contains 2 parts such that
part a: Where the probe is submerged in water. In this case the wattage of heater is 90.47 W
part b: Where the probe is on a vessel. In this case the wattage of heater is So 121.34 W
Explanation:
Part a
For the first part when it is assumed that the probe is submerged in the water. In this case the heat loss is only due to the convective heat transfer which is given as

Here
- Q is the heat loss which is to be calculated
- A is the area of the body which is given as
. It is calculated as

- Tbody is 10 C
- Tsurr is 0C
- h is the convection coefficient of water which is 18 W/m^2K

So the wattage of heater is 90.47 W
Part b
Now when the probe is above sea water now, the losses are both because of convection and radiation now the loss is given as

Here
- Q_con is the heat loss due to convection which is to be calculated
- A is the area of the body which is given as 0.5026 m^2
- Tbody is 10 C
- Tair is -10C
- h is the convection coefficient of water which is 10 W/m^2K

Radiation loss is given as
Here
- Q_rad is the heat loss due to radiation which is to be calculated
- A is the area of the body which is given as 0.5026 m^2
- Tbody is 10+273=283K
- Tsky is 0+273=273K
- ε is the emissivity of the shell which is 0.85
- τ is the coefficient which is


So the total value of heat loss is

So the wattage of heater is 121.34 W
Answer:
use a calculator to solve that
Yes, It probably true. Because the Luster it has a nonmetal, is going to be found in periodic table.
Hope it helped you.
