Answer:
= 9.8°
Explanation:
Width of one slit (a₁ ) = 1 / 1000 mm=0.001 mm = 10⁻⁶ m.
width of one slit in case 2 (a₂ ) = 1/500 =2 x 10⁻⁶ m
angular position of fringe, Sinθ = n λ /a
n is order of fringe , λ is wave length of light and a is slit aperture
So Sinθ ∝ 1 / a
Sin θ₁ /Sin θ₂ = a₂/a₁ ;
Sin20°/sinθ₂ = 2 / 1
sinθ₂ = Sin 20° / 2 = .342/2 = .171
θ₂ = 9.8 °
Sports like swimming and track are individual races but in the end everyone on the team races come together to make a team placement.
Absolutely, as anomilies can show inconsistencies with data and hypothesis they may have and may actually assist in refining the accuracyof their ideas by not only encompassing the most commonly-occuring phenomena, but also the more seldom occuring scenarios as well.
16.42 seconds will elapse between passing B on the way up and coming back to B on the way down.
<h3>What is the definition of Angular Speed? </h3>
The rate of change of angular displacement is defined as angular speed, and it is stated as follows:
ω = θ t
Where,
θ is the angle of rotation,
t is the time
ω is the angular velocity
Given data;
sin a = 2/5
a=sin(2/5)
a=23°
The linear velocity is the product of the angular velocity and the length.
The times between the two points are found as;
Hence, the time between passing B on the way up and returning to B on the way down will be 16.42 sec.

Answer: 164Nm
Explanation: the torque exerted on the wheel is given by the expression
Torque=force*radius(of steering wheel )
Given force =94.8N
Diameter of wheel=34.6cm
Radius =34.6/2 =17.3cm
to metre 17.3/10= 1.73m
Torque =94.8*1.73
=164Nm
