Answer:

Positively charged particle trajectories always follow electric field lines because the electric force on a positively charged particle is in the same direction as the electric field.

Explanation:

For any positive charge the electric field emerges radially outwards and it goes radially inwards for the negative charges.

  • From the theory of electric field lines we know that they never intersect each other, either they get merged when the sources are unlike or they repel when the sources are alike. In other words the electric field lines align in the same direction as that of the field.
  • So, when a positive charge is released into the an electric field they follow the direction of the field lines because they too have their field lines emerging radially outwards and hence these lines align in the direction of the field.

Which celestial body would have the strongest gravitational pull on a satellite orbiting 100 km above its surface?
8090 [49]
According to the Law of Universal Gravitation, the gravitational force is directly proportional to the mass, and inversely proportional to the distance. In this problem, let's assume the celestial bodies to be restricted to the planets and the Sun. Since the distance is specified, the other factor would be the mass. Among all the celestial bodies, the Sun is the most massive. So, the Sun would cause the strongest gravitational pull to the satellite.

If ice has a density of.92g/cm, what is the volume of 1.8 kilograms of ice?
steposvetlana [31]
Given:
Density = .92 g / cm³
Volume = 1.8 kg
            = (1.8 * 1000) grams
            = 1800 grams
Now,
Density (d) = \frac{Mass (m)}{volume(v)}

volume (v)= \frac{mass(m)}{density(d)}

volume (v)= \frac{1800}{.92}

volume (v)= 1956.521739

volume (v)= 1956.5~ cm^{3}

So, the volume of 1.8 kg of ice is 1956.5 cm³

Here it is an application of Newton's III law

as we know by Newton's III law that every action has equal and opposite reaction

So here as we know that two boys jumps off the boat with different forces

from front side of the boat the boy jumps off with force 45 N which means as per Newton's III law if boy has a force of 45 N in forward direction then he must apply a reaction force on the boat in reverse direction of same magnitude

So boat must have an opposite force on front end with magnitude 45 N

Now similar way we can say

from back side of the boat the boy jumps off with force 60 N which means as per Newton's III law if boy has a force of 60 N in backward direction then he must apply a reaction force on the boat in reverse direction of same magnitude

So boat must have an opposite force on front end with magnitude 60 N

So here net force due to both jump on the boat is given by

F_{net} = F_1 - F_2

F_{net} = 60 - 45

F_{net} = 15 N

so boat will have net force F = 15 N in forward direction due to both jumps

In places of hot climate it is advised that the outer walls of houses be painted white. Explain.
goblinko [34]

Darker colors absorb heat, While lighter colors don't. If a house is painted black in Arizona, The black color will absorb the heat making the temperature inside the house very hot even with the AC on. If a house in Arizona is painted White, The heat will bounce off the White color, making the temperature inside the house cooler.

Hope this helps!
