The magnitudes of the moon and sirius are -12.5 and -1.44, respectively. approximately how many times is the moon brighter than
1 answer:
Solution:
we are given that
The magnitudes of the moon and Sirius are -12.5 and -1.44 respectively.
we have been asked to find approximately how many times is the moon brighter than Sirius?
The word magnitude is used by the scientist to describe the brightness of moon/star/object etc.
So we can find the brightness by dividing the given values. so we get
Hence we can say
The moon is 8.68 times brighter than Sirius.

Answer:
The lateral Area of a cube
Step-by-step explanation:
In Mathematics Geometry, the lateral surface of a solid object like cube would be the face of the sold on its side, excluding base. Meaning, any surface, apart from base, would be included to determine the lateral surface of the solid.
A cube has six sides - also called faces.
A cube has a base i.e. the bottom side of the cube, and an ant-bottom base i.e. the top side of the cube.
So, lateral area of a cube would exclude both bottom side base and anti-bottom side base. In other words, it is the area of all the sides of the object, excluding the area of its base and top.
Hence, lateral area of a cube is the square of all the remaining four sides of the object, excluding the area of its base and top.
Hence, the lateral area of a cube can be calculated by the formula:
Lateral Area of a cube , where s is the length of one edge.
So,
As the given length of edge = s = 2.1
So,
lateral Area of a cube
