Answer:
The query will return four (4) rows
Explanation:
(See attachment below for the table)
The query will return rows where ORDERID is the same on both tables i.e. table ORDERS and ORDERLINES.
The similar rows (on column ORDERID) are 1897 and 87; for table ORDERLINESS and table ORDERS.
But on table ORDERLINESS, there are three rows with 1897 (under ORDERID column).
In total, they have 4 rows in common which are
ORDERID
1897
1897
1897 and
87
Answer:
230.4W
Explanation:
Heat transfer by conduction consists of the transport of energy in the form of heat through solids, in this case a jacket.
the equation is as follows
Where
Q=heat
k=conductivity=0.04
A=Area=1.8m^2
T2=33C
T1=1C
L=thickness=1cm=0.01m
Q=230.4W
the skier loses heat at the rate of 230.4W
Answer:
The answer is "+9.05 kw"
Explanation:
In the given question some information is missing which can be given in the following attachment.
The solution to this question can be defined as follows:
let assume that flow is from 1 to 2 then
Q= 1kw
m=0.1 kg/s
From the steady flow energy equation is:
If the sign of the work performed is positive, it means the work is done on the surrounding so, that the expected direction of the flow is right.
