What happens to momentum when two objects collide

Physics
1 answer:
Lostsunrise [7]3 years ago
3 0

Answer:

The sum of momenta of each object before and after collision is equal . Thus when they collide , their momentum will change but its sum will be sane as the sum of the momentum before collision

Para que ángulo el alcance es igual a la altura máxima en un lanzamiento de proyectil ideal sobre un plano horizontal. Translati
Gemiola [76]

Answer:

<h2>76°</h2>

Explanation:

In projectile,

Maximum height = \frac{u^{2}sin^{2} \theta  }{2g} and range = \frac{u^{2}sin2\theta }{g}

u = velocity of the body

\theta = angle of launch

g = acceleration due to gravity

If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

\frac{u^{2}sin^{2} \theta  }{2g} = \frac{u^{2}sin2\theta  }{g}

since sin2\theta = 2sin\theta cos\theta

\frac{u^{2}sin^{2} \theta  }{2g} = \frac{u^{2}2sin\theta cos\theta }{g}\\\frac{sin\theta}{2} =2cos\theta \\sin\theta = 4cos\theta\\\frac{sin\theta}{cos\theta}  = 4\\tan\theta = 4\\\theta = tan^{-1} \\4\theta = 75.9^{0}

The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°

Why are valence electrons so important?
natka813 [3]

Answer:

B. They are the electrons that interact with other atoms.

Explanation:

Valence electrons are the electrons in the outermost shell of an atom. These electrons are used by atoms to form bonds with other atoms during chemical bonding.

  • So, the basis by which atoms interacts with one another is through the valence electrons.
  • Without the valence electrons, atomic combination to form compounds would not be possible.
  • Valence electrons are the most loosely held electrons and they have the lowest ionization energy.

If a point has 40 J of energy and the electric potential is 8 V, what must be the charge?
Alekssandra [29.7K]

If a point has 40 J of energy and the electric potential is 8 V, the charge must be: A. 5 C

<u>Given the following the details;</u>

  • Energy = 40 Joules
  • Electric potential = 8 Volts

To find the quantity of charge;

Mathematically, the quantity of charge with respect to electric potential is given by the formula;

Quantity \; of \; charge = \frac{Energy}{Electric \; potential}

Substituting the values into the formula, we have;

Quantity \; of \; charge = \frac{40}{8}

<em>Quantity of charge = 5 Coulombs</em>

Therefore, the quantity of charge must be <em>5 Coulombs.</em>
