MULTIMETER combines the functions of ammeter, voltmeter and ohmmeter as a minimum.
Answer:
Explanation:
Hello,
In this case, since we compute the required energy via:
Whereas m is the mass which here is 70 g, C the specific heat which for water is 4.184 J/(g°C) and ΔT is the temperature difference which is:
Therefore, the energy turns out:
Best regards.
Answer:
23.99N
Explanation:
Given:
Pressure created by the heart = 120mm of hg
converting the pressure into the standard unit of N/m²
1mm of hg =
now, 120 mm of hg in N/m² will be
120mm of hg =
also
given effective area = 15.0 cm² = 15 × 10⁻⁴m²
Now,
Force = Pressure × Area
thus,
Force exerted will be = × 15 × 10⁻⁴m²
or
Force exerted will be = 23.99N
<u>Answer: </u>
