You use the right hand rule. With your thumb out and the rest of your fingers curved ( like a thumbs up) curve your fingers to the direction of the torque. The direction your thumbs points at is the direction of the torque
To solve this problem it is necessary to apply the concepts related to the Period based on the length of its rope and gravity, mathematically it can be expressed as
g = Gravity
L = Length
T = Period
Re-arrange to find the gravity we have
Our values are given as
Replacing we have
Therefore the correct answer is C.
Answer:
Explanation:
To find the force we proceed by defining the variables we have,
The charge on one of the balls is defined under the equation,
Due to the height we need to calculate the potential energy at the height of 115m,
The kinetic energy would be given by
From the law of conservation we equate the two equations
In this way we now calculate the strength of the particle
Answer:
C. Evaporating water from the container.
Explanation:
The concentration of solution changes when solvent or solute are added/removed from a solution.
Due to the decay of naturally radioactive substances, or even due to the heat made by the movement of the tectonic plates, and formation of gravitational acceleration, the temperature increases.
