Answer:
The answer is below
Explanation:
a) The weight of the combined system is the sum of the weight of the water and the weight of the tank
b) Since the weight of a system can be divided into smaller portions, hence weight is an extensive property.
c) When analyzing the acceleration of gases as they flow through a nozzle, the geometry of the nozzle which is an open system can be chosen as our system.
d) Given that:
Good fats are also called unsaturated fats. They're found in foods like olives, nuts, avocado, and fish. Cut sources of saturated fat, such as fatty meat and dairy. Choose lean cuts of meat, and try eating more plant-based meals.

Answer: The normalized corrected value at 32.5 mm = 0.69 mV
Explanation:
Signal value V1 = 20.7 mV at
distance value = 29 mm and
V2 = 15.8 mV is measured at 32.5 mm.
It is necessary, therefore, to subtract off this background level from the data to obtain a valid measurement
V1 = 20.7 - 5.1 = 15.6 mV
V2 = 15.8 - 5.1 = 10.7mV
The normalized corrected value at 32.5 mm will be
Vn = V2/V1 since V1 is the maximum value
Vn = 10.7/15.6 = 0.69 mV
Answer:
Q=I^2Rt
Explanation:
The principle of resistance welding is the Joule heating law where the heat Q is generated depending on three basic factors as expressed in the following formula
Q=I^2Rt
I is the current passing through the metal combination
R is the resistance of the base metals and the contact interfaces
t is the duration/time of the current flow.
