M = 4kg
F =8N
a..?
F =m.a
8 = 4.a
a = 2m/s^2
Answer:
Explanation:
slit separation d = .17 x 10⁻³ m.
Screen distance D = 5.35 m
angular separation of fringe = λ /d ; λ is wavelength.
Given angular separation in radian
180° = π radian
.19° =
=.0033 radian
.0033 =
λ = .0033 x d
= .0033 x .17 x 10⁻³
= 561 x 10⁻⁹
= 561 nm.
Answer:
The net force acting on this object is 180.89 N.
Explanation:
Given that,
Mass = 3.00 kg
Coordinate of position of
Coordinate of position of
Time = 2.00 s
We need to calculate the acceleration
For x coordinates
On differentiate w.r.to t
On differentiate again w.r.to t
The acceleration in x axis at 2 sec
For y coordinates
On differentiate w.r.to t
On differentiate again w.r.to t
The acceleration in y axis at 2 sec
The acceleration is
We need to calculate the net force
The magnitude of the force
Hence, The net force acting on this object is 180.89 N.
