The force of the truck on the car is equal to the force of the car on the truck.

<h3>What is Newton's third law of motion?</h3>
  • Newton's third law of motion states that action and reaction are equal and opposite.

Let the mass of the small car = m

Let the mass of the truck = M

The force exerted by the small car is calculated as;

F₁ = ma

The force exerted by the large truck is calculated as;

F₂ = Ma

According to Newton's third law, the magnitude of the two forces are equal but opposite in direction.

|F₁| = |F₂|

Thus, we can conclude that, the force of the truck on the car is equal to the force of the car on the truck.

The type of chemical bond that involves the transfer of electrons between atoms is a(n) bond.
GaryK [48]
<h3>Answer;</h3>

<em>-Ionic bond</em>

<h3>Explanation;</h3>
  • <u>Ionic bond</u> is a type of bonds that results from transfers of electrons from one atom to another.  This types of bond is formed between metals and non metals.
  • Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion.
  • For instance; between sodium and chlorine element; sodium donates a single electron to attain a stable configuration while chlorine gains an electron to achieve stable configuration, thus forming an ionic compound sodium chloride.

If Earth had twice the mass it has now, how would the gravitational force between it and the Sun change?
zhenek [66]

Answer:

a)The gravitational force would be twice as much as it is now

Explanation:

If the earth had twice its mass as it is now, the gravitational force between the sun and the earth would be twice as much as it is now.

According to Newton's law of universal gravitation "the gravitational force of attraction between bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

       F_{g}   = \frac{G m _{e} m _{s}  }{r^{2} }

G is the universal gravitation constant

m is the mass

r is the distance

let mass of sun  = s

     mass of earth  = e

 new mass of sun  = s

 new mass of sun  = 2e

input variables;

    F  = \frac{Gx e x s}{r^{2} }    ------ i

   F = \frac{G  x s x 2e}{r^{2} }    ------- ii

From the second equation;

      2F  = \frac{Gx e x s}{r^{2} }

      2F  = F

Therefore, the force will double.
