Dmitriy789 [7]3 years ago
4 0

Answer:

"*The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.

*The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.

*The reflected ray and the incident ray are on the opposite sides of the normal."

A right triangle has sides measuring 5 and 12 inches. If the two vectors have a magnitude of 5 and 12 and are at right angles to
ollegr [7]

Answer:

x=13

Explanation:

From the question we are told that

Magnitude 1 M_1=5

Magnitude 1 M_2=12

Generally the Pythagoras equation for the magnitudes is mathematically given as

\sqrt{x^2}=\sqrt{M_1^2 +M_2^2}

\sqrt{x^2}=\sqrt{5^2 +12^2}

x=13

Therefore resultant magnitude is

x=13

1. A 12 kilogram block is sitting on a platform 24 m high. How much Potential energy does
Mazyrski [523]

The amount of potential energy the block contains is 2,822.4 Joules

<u>Given the following data:</u>

  • Mass of block = 12 kg
  • Height of platform = 24 meters.

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 m/s^2.

To determine the amount of potential energy the block contains:

Mathematically, potential energy (P.E) is given by the formula;

P.E = mgh

Where:

  • m is the mass of object.
  • g is the acceleration due to gravity.
  • h is the height of an object.

Substituting the parameters into the formula, we have;

P.E = 12 \times 9.8 \times 24

Potential energy (P.E) = 2,822.4 Joules
