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
Answer:
292.31 m/s
Explanation:
If Distance (d) = 190m
Time (t) = 1.3s
Speed of sound in air (v) =?
then
2d=vt
v=2d/t
v= 2×190/1.3
v=292.31 m/s
Answer:
Option A
Explanation:
The correct answer is Option A.
At room temperature, the resistance is equal to 100 ohms.
When the temperature is reduced to 77 K from room temperature, change in the resistance is very less.
The temperature coefficient of the resistivity of most of the metal is small for the metals which are approximately equal 0.01 /K.
hence, Change is only slightly.
