Answer:
8.62m/s²
Explanation:
the particle is experiencing both translational and circular motion
v=4t²
=
=8t
at t=1s, =8(1)=8m/s²
=
at t=1, v= 4(1)² = 4m/s
=4²/5
=3.2m/s²
∴ magnitude of total acceleration, a
a=
a=
a=
a=
a=8.62m/s²

Steady state temperature is approximately 801K
Explanation:
Detailed explanation and calculation is shown in the images below.
Answer:
C = 59.17 nF
Q = 2.6
Explanation:
given data
frequencies = 40k Hz
frequencies = 90k Hz
solution
we take here R, L C take in series
so cut off frequency is express as
Wc1 = = 40000
wc2 = = 90000
so here
wc2 - wc1 will be
wc2 - wc1 = 90000 - 40000 = 50000
so
= 50000
we consider here R is 500
so L =
L = 10 m H
and here total cut off frequency is
total cut off frequency = 40000 + 90000 = 130000
so capacitance will be
capacitance C is =
so C = 59.17 nF
quality factor Q will be
Q =
Q = 2.6
Answer:
Kindly check Explanation section.
Explanation:
NB: please check the attachment for the solution to: the boundary layer thickness, the displacement thickness, the momentum thickness the wall shear stress, the friction coefficient, and the drag coefficient for a flat plate with zero pressure gradient in a laminar flow.
===============================
So,for the solution the second part of the question that asked us to state;
What happens if we add a constant positive pressure gradient?
SOLUTION: Whenever we have dp/dx > 0 that is a positive pressure gradient then, we are going to have what is known as a divergent flow which makes pressure to increase in the direction of flow. The pressure will be minimum around the centre. Also, as the velocity decreases(velocity gradient becomes negative), the area of flow increases.
