Ep = mgh
= (35)(9.8)(3.5)
= 1200.5 J
Ek = (1/2)(mv^2)
= (0.5)(35)(5^2)
= 437.5 J
Answer:. True
Explanation:
The risk of becoming infected from contact with an HIV-positive healthcare provider is indeed remote. The Centers for Disease Control and Prevention (CDC) have recommended the use of universal precautions by healthcare providers to minimize the risk of transmitting many infectious diseases, including hepatitis and HIV. The risk of transmission from patient to healthcare provider is far greater than from provider to patient.
Answer:
The answer is E) 20kPa
Explanation:
Here we use the definition of Pressure: Pressure is a physical quantity that measures the projection of force in the perpendicular direction per unit area. In this case, wehave a 200N Force over a 100cm^2 Area
In order to have the pressure in international units we need to convert those cm^2 to m^2 this way:
We know 100cm is equal to 1m
In this case, the area will be equal to 0,01m^2
With this information we use the Pressure equation, which based on the definition will be:
Solving:
Then P is the same as 20kPa
