Answer:
Explanation:
Given that the grand stone has initial angular velocity of
w(ini)= 6rad/
And it has a final angular velocity of
w(fin)=12.20rad/sec
Time taken is t=16s
Using equation of angular motion
To get angular acceleration (α)
w(fin)=w(ini)+αt
12.20=6+16α
16α=12.20-6
16α=6.2
α=6.2/16
α=0.3875rad/sec²
The angular acceleration is 0.39rad/s²
Angle that he turn using
w(fin)²=w(ini)²+2αθ
12.2²=6²+2×0.3875θ
12.2²-6²=0.775θ
0.775θ=112.84
Then, θ=112.84/0.775
θ=145.6radian
The angular displacement is 145.6rad
As it is outside the focal point it must be real.Real images must be inverted.
As it is beyond the centre of curvature it is also beyond 2F which means that the image is inside the centre of curvature ( between F and 2F from the mirror ) As the image is closer to the mirror than the object it must be diminished in size.
Hope this helps you :)
The Drake equation calculates the civilization parameter as
R*fp*ne*fl*fi*fc*L = 1 x 1 x 0.1 x 1 x 1 x 1 x 100 = 10.
If each increasable factor is multipled by 10, the result will be
(1*10) x (1*10) x (0.1*10) x (1*10) x (1*10) x (1*10) x (100*10)
= 10 x 10⁷
= 10⁸
Answer: 10⁸
Answer:
Explanation:
We are given that
Mass of charged tine spheres=m=1 g=
1 kg=1000g
The distance between charged tine spheres=r=2 cm=
1 m=100 cm
Acceleration =
Let q be the charge on each sphere.
The electric force between two charged particle
Using the formula
The force between two charged tiny spheres=
According to Newton's second law , the net force
Hence, the magnitude of charge on each tiny sphere=
