Answer:
Explanation:
PE = mgh where m is the mass in kg, g is the pull of gravity which is 9.8, and h is the height of the object above the point to which it could possibly fall, measured in meters. Plugging in:
PE = 10(9.8)(20) so
PE = 1960 J
This should be rounded to 1 sig fig according to the rules of sig fig and your numbers here, but I imagine you're not following them all that much. It should be 2000 J

Frequency - 50Hz. Which means that the time period of the wave if 1/50 = 0.02 sec. Here we are going to check the average voltage for the time interval of 0.01sec. If the interval lies between π/2 to 3π/2. the average voltage will be zero. In all the other cases it will not be zero

Answer:
Solid - molecules are packed together, and it keeps its shape.
Liquids - take the shape of the container.
Gases - spread out to fill the container.
The magnitude of the force acting on the object lying on a flat surface without moving is 10 N.
The given parameters;
- magnitude of force on the object, F = 10 N
- angle between the object and the horizontal flat surface = 0⁰
Apply Newton's second law of motion to determine the magnitude of the force on the object.
Due to the position of the object, the magnitude of the force acting on it is calculated as;
Therefore, the magnitude of the force acting on the object is 10 N.
