Imagine a block with A pulling one way and B the other.
If A is bigger than B then obviously it will go in the direction of A.
The net force will be A-B as A is pulling it along with x but b is also pulling back with y.
Power is energy/time where energy is in joules and time is in seconds. The units for power is watts, W.
P = 500J/30s = 16.67 W
Hope this helps!
The structure of an atom is in the middle of an atom has the neutron (nucleus) which has no charge around the neutron is the protons which has a positive charge and the ones that orbit around the atom is the electrons which has a negative charge in it. The number of protons is call the Atomic Number. Protons have a relative charge of +1 and the electron have a relative charge of -1.
The angular momentum of earth is
7×10^33 kgm^2/sec
Given:
mass of earth = 5.98×1024 kg
radius of earth = 6.38×10^6 m
To Find:
angular momentum
Solution:
For earth we have moment of inertia as
I = 2/5mR^2
and angular velocity as ω = 2π/T
Thus angular momentum is given as
L= 2/5mR^2*2π/T
L = 2/5*5.98×10^24*(6.38×10^6)^2*2*3.14/86400s
L = 7 × 10^33 kg/m^2/sec
So, angular momentum of earth is
So, angular momentum of earth is 7×10^33 kgm^2/sec
