Answer:
194516 sheets
Explanation:
So the area of each sheet of paper is:
A = 0.216 * 0.279 = 0.060264 square meters
For the paper sheet to make the same effect as the atmospheric pressure P, then the gravity F from the paper sheet must be
F = AP = 0.060264 * 101325 = 6106 N
Let g = 9.81 m/s2, then the mass of paper needed to generate that gravity is
m = F/g = 6106 / 9.81 = 622.4 kg
If each sheet has a mass of 0.0032 kg, then the total number of sheets to have that much mass is
622.4 / 0.0032 = 194516 sheets
This one is also using pre-conventional moral reasoning.
<span>(a) 0.0676 l
(b) 67.6 cc
So we've been told that 5.00 L of blood flows through the heart every minute and that the heart beats 74.0 times per minute. So that means that for every beat of the heart, 5.00 L / 74.0 = 0.067567568 L of blood flows through the heart. Rounding to 3 significant figures gives 0.0676 l. Converting from liters to cubic centimeters simply require a multiplication by 1000, so we have 67.6 cc of blood pumped per beat.</span>
Answer:
C. Hot pavement burning your feet
Explanation:
Convection is a type of process where heat travels upwards and cold travels downwards.
<span>An emf is induced when a magnet is in the middle of coil because when a magnetic field is changing then it produces a voltage in the coil, which causes a current to flow. If the coil is changed through a magnetic flux, then a voltage is produced.</span>
