Hes using different fabrics that might affect the temperature.
Answer:
41 turns
Explanation:
= Induced emf = 12.4 mV
= Current changing rate = 0.0275 A/s
L= Inductance
= Average flux = 0.00285 wb
N = Number of turns
Change in flux is given by
Flux through each turn is given by
The number of turns is 41
Answer
given,
mass of the block = 200 g = 0.2 Kg
Velocity at A = 0 m/s
Velocity at B = 8 m/s
slide to the horizontal distance = 10 m
height of the block be = 4 m
potential energy of the block
P = m g h
P = 0.2 x 9.8 x 4
P =7.84 J
kinetic energy
Work = P - KE
work = 7.84 - 6.14
work = 1.7 J
b) v² = u² + 2 a s
0 = 8² - 2 x a x 10
a = 3.2 m/s²
ma - μ mg = 0
Answer:
1) Force on top face
2)Force on the side face
Explanation:
a)
We know that
Pressure shall be calculated at a depth of (1-0.45) meters from the top of the water surface
Thus force is calculated as under
b)
The force on one of it's sides is calculated in the same manner except that the pressure is obtained at the centroidal level of the face of cube
Thus
