Answer:
Electric field, E = 0.064 V/m
Explanation:
It is given that,
Resistivity of silver wire,
Current density of the wire,
We need to find the magnitude of the electric field inside the wire. The relationship between electric field and the current density is given by :
E = 0.0636 V/m
or
E = 0.064 V/m
So, the magnitude of electric field inside the wire is 0.064 V/m. Hence, this is the required solution.
Explanation:
Density is defined as the ratio of the mass to the volume. The expression for density is:
The Si unit for density is kg/m³
The dimensional expression for density = [ML⁻³]
Specific volume is defined as the ration of the volume to the mass. It is the reciprocal of density.
The BG unit of specific volume is ft³ / lb.
Answer:
(a) when the distance x is 0.3 m, the boundary layer thickness is 0.0055 m = 5.5 mm.
(b) when the distance x is 3 m, the boundary layer thickness is 0.0174 m = 17.4 mm.
(c) when the distance x is 30 m, the boundary layer thickness is 0.055 m = 55 mm.
Explanation:
For a laminar flow:
;
where;
d is the boundary layer thickness = 11 mm
x is the distance from the leading edge = 1.2 m
C is a constant =?
<u>Part (a):</u> when x = 0.3m
d = C√x
= 0.010042 × √0.3
= 0.0055 m = 5.5 mm
<u>Part (b):</u> when x = 3.0 m
d = C√x
= 0.010042 × √3.0
= 0.0174 m = 17.4 mm
<u>Part (c):</u> when x = 30 m
d = C√x
= 0.010042 × √30
= 0.055 m = 55 mm
On and around drop-offs in the ocean
See the bullet will have a parabolic path both the components should be solved separately thus the y-axis path will be a free fall as there won't be any velocity vector there
so we get
√2h/g= t
√2*78.4/9.8 = t
thus t= 4sec
it means it would take 4 sec to travel 1500 metres
so 1500/4 = 375 m/s would be velocity !
