Answer:
See the answer below.
Explanation:
The weight of the table should be equal to the weight of the table plus the weight of the book.
![w_{table}=m_{table}*g\\w_{table}=200*9.81\\w_{table}=1962[N]](https://tex.z-dn.net/?f=w_%7Btable%7D%3Dm_%7Btable%7D%2Ag%5C%5Cw_%7Btable%7D%3D200%2A9.81%5C%5Cw_%7Btable%7D%3D1962%5BN%5D)
And for the book
![w_{book}=m_{book}*g\\w_{book}=50*9.81\\w_{book}=490.5[N]](https://tex.z-dn.net/?f=w_%7Bbook%7D%3Dm_%7Bbook%7D%2Ag%5C%5Cw_%7Bbook%7D%3D50%2A9.81%5C%5Cw_%7Bbook%7D%3D490.5%5BN%5D)
And the total weight
![w = w_{table}+w_{book}\\w=1962+490.5\\w = 2452.5 [N]](https://tex.z-dn.net/?f=w%20%3D%20w_%7Btable%7D%2Bw_%7Bbook%7D%5C%5Cw%3D1962%2B490.5%5C%5Cw%20%3D%202452.5%20%5BN%5D)
For the system to be in balance, the reaction force exerted by the table on the book must be equal to the weight of the book. This force in physics is known as the normal force.
![N_{force} = w_{book}\\N_{force}=490.5[N]](https://tex.z-dn.net/?f=N_%7Bforce%7D%20%3D%20w_%7Bbook%7D%5C%5CN_%7Bforce%7D%3D490.5%5BN%5D)
We can calculate the resistance of the radio circuit by using Ohm's law:

where
V is the voltage of the circuit
I is the current
R is the resistance
In this circuit,

and

. If we rearrange the previous equation and we use these data, we can calculate the resistance of the circuit:
Answer:
How do you find the average speed in physics?
Average speed is calculated by dividing distance by time (e.g. miles/hour
