Answer:
The weight of the body in the new planet is 100 newtons.
Explanation:
From Newton's Law of Gravitation we find that gravitational force is directly proportional to mass of the planet and inversely proportional to the square of its radius. From this fact we can build the following relationship:
(1)
Where:
,
- Gravitational force, measured in newtons.
,
- Mass of planet, measured in kilograms.
,
- Radius of the planet, measured in meters.
If we know that
,
and
, then the expected gravitational force in the new planet is:



The weight of the body in the new planet is 100 newtons.
The current in the second diode is 400mA
Data;
- First Voltage = 0.75V
- Second Voltage = 0.8V
- First Current (I) = 400mA
- Second Current(I) = ?
<h3>Current In a Series</h3>
The current in the first diode is equal to 400mA. In a series circuit, the current passing the diodes are equal. This implies that the current in the series are equal.
Diodes connected in series will be the equal.

Since I1 is 400mA, I2 will be equal to 400mA

The current in the second diode is 400mA

The distance covered in one orbit is equal to the circumference of earth.
Given that radius of earth is 3959 miles.
Circumference of earth= 2πr = 2*3.14*3959 = 24875.13 miles
Speed is 26,000 miles per hour.
Since, Velocity= Distance/Time
Time= Distance/Velocity = 24875.13/26000
Time = 0.9567 hours
Therefore,
Average hour per orbit is 0.957 approximately.
