1. Calcula la fuerza de atracción electrostática entre dos cuerpos de cargas q1 = -18 C y q2 = +5 mC, separados entre sí por una
romanna [79]

Answer:

A) F=-20.16×10⁹N

B) if the distance doubles, force is 4 times smaller.

Explanation:

q1=-28C

q2=5mC=0.005C

d=25cm=0.25m

Electrostatic force between charges: F=k×q1×q2/d², where k is a coefficient that has the value k=9 × 10⁹ N⋅m²⋅C^(-2) for air.

Thus:

F=9×10⁹×(-28)×0.005/0.25²

F=-20.16×10⁹N

The minus sign indicates attraction.

If distance doubles, d1=2×d, then we have 4d² at the denominator and the force is 4 times smaller.

Your hands get warm by a fire because _____energy is converted into heat energy​
MaRussiya [10]

Answer:

Your hands get warm by fire because chemical energy gets converted into heat energy. When the chemical bonds in the wood are released in the air which then mixes with oxygen and emit heat. This is the reason why it is always hot when you go near something that is burning or is up in flames.

Which statement best describes the situation? Which statement best describes the situation? The car has the greater change of mo
Pachacha [2.7K]

Complete Question

A truck going 15 km/h has a head-on collision with a small car going 30 km/h. Which statement best describes the situation?

A. the truck has the greater change of momentum because it has the greater mass

B. the car has the greater change of momentum because it has the greater speed

C. neither the car nor the truck changes its momentum in the collision because momentum is conserved

D. they both have the same change in magnitude of momentum because momentum is conserved

E. none of the above is necessarily true

Answer:

D. They both have the same change in magnitude of momentum because     momentum is conserved

Explanation:

In order to get a good understanding of the solution above we define some

concetps

   Momentum

This is defines quantified motion and can be mathematically represented as  

      Momentum =  Mass of the body × Velocity of the body

According to the Law of conservation of momentum states that when two particles collide together in a system that is being isolated that their total momentum before and after their collision is equal this means that the momentum lost by the truck would be the same as the momentum gained by the small car
