Answer:
c- interact with charged particles.
Explanation:
When a charged particle is placed in the field of the other charged particle then it will experience electromagnetic force on it.
As we know that force on a charged particle due to some other electric field is given by
F = qE
here we know
q = charge
E = electric field intensity
Similarly when a charged particle is placed in external magnetic field then the force on that moving charge is given by
so here if charge is moving in the magnetic field due to some other system then the force on it is given by above equation.
So here we can say that electromagnetic force is present when electromagnetic fields
c- interact with charged particles.

Answer:
Explanation:
1. We use the conservation of momentum for before the raining and after. And also we take into account that in 0.5h the accumulated water is
100kg/h*0.5h = 50kg
2. the momentum does not conserve because the drag force of water makes that the boat loses velocity
3. If we assume that the force of the boat before the raining is
where we have assumed that the acceleration of the boat is 1m/s{2} just before the rain starts
And if we take the net force as
where we take v=1m/s because we are taking into account tha velocity just after the rain stars.
I hope this is useful for you

Answer: A. 24,000,000,000 km
Explanation: An Astronomical Unit commonly abbreviated as AU is the average distance between Earth and the Sun and is about 150 million kilometers.
Astronomical unit is mainly used to measure distances within our solar system.
1 AU is equal to km
Thus 160 AU is equal to
