The gravitational force on two objects can be determined by the following equation:

Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:


F=4.17x10^23 N
The conservation of the mass of fluid through two sections (be they A1 and A2) of a conduit (pipe) or current tube establishes that the mass that enters is equal to the mass that exits. Mathematically the input flow must be the same as the output flow,

The definition of flow is given by

Where
V = Velocity
A = Area
The units of the flow of flow are cubic meters per second, that is to say that if there is a continuity, the volume of input must be the same as that of output, what changes if the sections are modified are the proportions of speed.
In this way


Answer:The bulb did not glow as the switch is not turned on which obstructs electric current to flow through it. Also, the battery in the figure has both terminals as positive. It should be one negative terminal and one positive terminal.Redrawn diagram is also given

Answer:
Speed of the hawk, v = 40.4 m/s
Explanation:
It is given that,
Exact frequency of the female, f = 785 Hz
Observed frequency of female, f' = 890 Hz
Speed of sound, v = 343 m/s
Let v' is the speed of the hawk. It is based on the concept of Doppler's effect. We know that when the object approaches you, its speed is given by :


v' = 40.4 m/s
So, the speed of the hawk is 40.4 m/s. Hence, this is the required solution.
