<h3><u>Answer;</u></h3>

<em>When a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave</em>

<h3><u>Explanation</u>;</h3>
  • <em><u>Reflection is the property of waves in which the waves bounces back upon meeting or hitting the surface of an object or a boundary.</u></em> It may also refer to the change in the direction of a wave when it meets an interface between two media.
  • Therefore, when a wave such as light waves meets an opaque surface, they will bounce back off the surface.
  • <em><u>The reflection of waves obeys the Laws of reflection such that the angle of reflection is equal to the angle of incident wave.</u></em>

A plate drops onto a smooth floor and shatters into three pieces of equal mass.Two of the pieces go off with equal speeds v at r
Firlakuza [10]

Answer:

Speed of the this part is given as

v_3 = \sqrt2 v

Also the direction of the velocity of the third part of plate is moving along 135 degree with respect to one part of the moving plate

Explanation:

As we know by the momentum conservation of the system

we will have

P_1 + P_2 + P_3 = P_i

here we know that

P_1 = P_2

the momentum of two parts are equal in magnitude but perpendicular to each other

so we will have

P_1 + P_2 = \sqrt{P^2 + P^2}

P_1 + P_2 = \sqrt2 mv

now from above equation we have

P_3 = -(P_1 + P_2)

mv_3 = -(\sqrt 2 mv)

v_3 = \sqrt2 v

Also the direction of the velocity of the third part of plate is moving along 135 degree with respect to one part of the moving plate

The car salesman tells you that the car can go from a stop position to 60 mph in six seconds is giving you the car’s rate of
slava [35]
The salesman is telling you the average magnitude of the car's acceleration.

| Acceleration | = (change in speed) / (time for the change)

| Acceleration | = (60 mi/hr) / (6 sec)

| Acceleration | =  10 miles/hr-sec

That would be 36,000 miles per hour squared,
or 0.0028 mile per second squared.

How do you balance this equation Mg+ O2= MgO
Anuta_ua [19.1K]

Answer:

2 Mg(s) + O2(g) → 2 MgO(s)

As magnesium (Mg) has a valency of +2, and oxygen (O) has a valency of -2, the ratio would be 1:1, and magnesium oxide would be represented as MgO. It is insoluble in water, hence it has the subscript as a solid, represented by (s). In order to use up the diatomic oxygen (O2), there needs to be two moles of magnesium (2Mg) on the reactant side. This would produce 2 moles of MgO on the product side.
