Determine the difference in the blood pressure from feet to top
This is calculated using Pascal's second law.
The second law is represented as:
Subtract P1 from both sides
Where
P2 - P1 = Blood Pressure Difference
So, the expression becomes:
Hence, the difference in blood pressure is approximately 
Answer:
C) experience a small induced magnetic moment when placed in an external magnetic field.
Explanation:
Diamagnetics materials are those that experience a small induced magnetic moment when placed in an external magnetic field. These materials, such as bismuth, copper, silver and lead, have elementary magnets in their compositions. When they are exposed to an external magnetic cap, these elemental magnets tend to follow an orientation contrary to the external magnetic field. As a result, a magnetic field is created in the opposite direction to the external magnetic field.
Answer:
C) High voltage to low voltage
Explanation:
At a power plant, there is a production of electricity at a high voltage compared to the voltage provided to our home.
Voltage of about 12 KV is produced by power plant which is then converted into about 400 KV or greater (depending upon the countries) to transfer electricity from power plant to city Grid station using Step-up transformer. At City Grid station, Step-down transformer is used to convert high voltage (about 400 KV) to low voltage (about 13 KV) to transfer electricity from grid station to the city. Then this low voltage (about 13 KV) again converted to 220 V using Step-down transformer for household usage. So, overall about 12 KV voltage at power plant is converted into 220 V for household usage using step-up and step-down transformer at different stages.
The answer is probably going to be b or d. hope that helped
