Answer:
V = 9.682 × 10^(-6) V
Explanation:
Given data
thick = 190 µm
wide = 4.20 mm
magnitude B = 0.78 T
current i = 32 A
to find out
Calculate V
solution
we know v formula that is
V = magnitude× current / (no of charge carriers ×thickness × e
here we know that number of charge carriers/unit volume for copper = 8.47 x 10^28 electrons/m³
so put all value we get
V = magnitude× current / (no of charge carriers ×thickness × e
V = 0.78 × 32 / (8.47 x 10^28 × 190 × 1.602 x 10^(-19)
V = 9.682 × 10^(-6) V
Answer:
Heat energy required = 687.96 kJ
Explanation:
Heat energy required, H = mCΔT.
Mass of cooking oil, m = 2.34 kg = 2340 g
Specific heat of cooking oil, C = 1.75 J/(g⋅°C)
Initial temperature = 23 °C
Final temperature = 191 °C
Change in temperature, ΔT = 191 - 23 = 168 °C
Substituting values
H = mCΔT
H = 2340 x 1.75 x 168 = 687960 J = 687.96 kJ
Heat energy required = 687.96 kJ
Answer:
Explanation:
Lithification is the process by which sediments compact under the influence of pressure and the sediments become rocks. This process limits the porosity by destruction of porosity by compaction and cementation.
Sandstone is clastic sedimentary rock that forms by the process of lthification which involves the compaction and cementation of sand grains.
