Answer:
Compared to High angle, relatively less presence of Crystallographic misalignment in grain boundary for small angle is reason behind its less effectiveness in interfering with slip process
Explanation:
Because of relatively much less presence of crystallographic misalignment in grain boundary for small angle, small grain boundaries are not as effective in compare to high angle in interfering with slip process
Less crystallographic misalignment in grain boundary causes not much change in slip direction and therefore interference to slip process is minimal.
Energy stored in the capacitor= 2.2 x 10⁻¹⁰ J
Explanation:
The energy stored in the capacitor is given by
E= 1/2 q V
E= energy stored
q= charge= 7.6 x 10⁻¹¹ C
V= potential difference=5.8 V
so energy stored= E= 1/2 (7.6 x 10⁻¹¹) (5.8)
Energy stored= 2.2 x 10⁻¹⁰ J
Explanation:
do we can say that the first step is finding the acceleration of the object. We do so by saying F = ma
so a = F/m
a = 500 m/s^2
we now have the time, acceleration and initial velocity.
so we can find the final velocity by using one of newtons equations which is: vf = vi + at
so:
vf = 0 + 500 × 12
vf = 6000
note that our initial velocity was zero since the object was initially at rest.
if you still have any doubt dont hesitate to ask for further help.

Answer:
α = 1.32 rad/s²
Explanation:
given,
diameter of the bicycle = 0.8 m
radius of the bicycle = 0.4 m
initial speed of the bicyclist,u = 0 m/s
final speed of the bicyclist,v = 22 Km/h = 22 x 0.278
= 6.12 m/s
time,t = 11.6 s
acceleration =
=
=0.53 m/s²
we know,
a = α r


α = 1.32 rad/s²
the angular acceleration of the wheels is equal to α = 1.32 rad/s²
