The resistance is 16 ohm's
V=I x R where V is the voltage, I is the current, and R is the resistance in Ohms
120= 15 x R
R=120/15
R= 8 Ohm's
P=VxV / R
P=120v x 120v / 8 ohms
P= 14400/8
P = 1800 watts
R = V x V/P
R = 14400/900
R = 16 Ohm's
The resistance is 16 ohm's:
I = V/R
I = 120/16
I = 7.5 Amps

Explanation:
SQL queries
The command used to display the customer ID and total number of orders placed is given below
Query:
SELECT CustomerID, COUNT (orderID) AS TotalOrders
FROM Order_Table
GROUP BY CustomerID
SELECT - To query the database and get back the specified fields SQL uses the select statement
CustomerID is a coloumn name
The function COUNT(OrderID) returns the number of orders
Totalorderds is a label
FROM - To query the database and get back the preferred information by specifying the table name
Order_Table is a table name
GROUP BY - The clause is used to group the result of a SELECT statement done on a table where the tuple values are similar for more than one column
The table below displays the CustomerID and total number of orders placed
CustomerID Totalorders
