Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Periods 4 and 5 have 18 elements. Periods 6 and 7 have 32 elements because the two bottom rows that are separated from the rest of the table belong to those periods.

Explanation:
<span>Since the wheel start from rest. angular acceleration,
θ=1/2αt²
14=1/2α x 8.7²
α= 0.3699 rad/s²
moment of inertia of loop= mr²= 4.1x0.37=1.517 kgm²
torque=T= lα
T= 0.5611Nm= 0.56Nm to significant figure
Disc
moment of inertia of disc= 1/2mr²
Required torque value= 0.28Nm
So,
I= 1/2X 4.1X 0.37²= 0.280 Kgm²
T= Iα = 0.280 X 0.3699= 0.10 to two significant figure</span>
Answer:
The calculations is shown below on the basis of equation:
work = force × distance
Explanation:
- Here the work done is 600 J and distance is certain cm ( assume 10 cm).
- As work done is the force applied for certain distance.
Mathematically,
work = force × distance
so,
force =
or, force =
or, force=
or, force = 6000 N
or, force = 6 KN
Hence taking distance as 10 cm, the force will be 6 KN.
