The figure given below shows the travelling of Bob. First he travels along east 110 m and then again travels 160 m. SO the displacement will be as shown by the figure.
Displacement =
= 194.16 m
SO displacement of Bob from his home = 194.16 m
Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
Explanation:
<span>Animal Y is an invertebrate, and animal Z is a vertebrate.
An x-ray can produce images of structures found inside the body. Based on the image, you can see that Animal Z has a backbone, which is a series of small bones called vertebrae that extend from the head. Animal Y does not have that structure.
Vertebrates are organisms that have a backbone and invertebrates are organisms that lack one. </span>
Answer:
Density = 1.14 kg/mm³
Explanation:
Given the following data;
Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³
Mass = 23.94kg
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Substituting into the equation, we have;
Density = 1.14 kg/mm³
