Answer:
Density is the mass to volume ratio of an object.
> It tells you how compact the mass is.
> Density = mass/volume
The density of water is 1 g/ml or 1 kg/L or 1000 kg/m3
• If an object has a density less than that of water, it
will float.
• If an object has a density more than that of water, it
will sink

Answer:
The oxidation number of a monatomic (composed of one atom) ion is the same as the charge of the ion. For example, the oxidation numbers of K+, Se2−, and Au3+ are +1, -2, and +3, respectively. The oxidation number of oxygen in most compounds is −2.

Answer: The mass of the sculpture is 11.8kg
Explanation:
Using the equation of fundamental frequency of a taut string.
f = (1/2L)*√(T/μ) .... (Eqn1)
Where
f= frequency in Hertz =80Hz
T = Tension in the string = Mg
M represent the mass of the substance (sculpture) =?
g= 9.8m/s^2
L= Length of the string=90cm=0.9m
μ= mass density = mass of string /Length of string
mass of string =5g=0.005kg
L=0.9m
μ=0.005/0.9 = 0.0056kg/m
Using (Eqn1)
80= 1/(2*0.9) √(T/0.0056)
144= √(T/0.0056)
Square both sides
20736= T/0.0056
T= 116.12N
Recall that T =Mg
116.12= M * 9.8
M=116.12/9.8
M= 11.8kg
Therefore the mass of the sculpture is 11.8kg
The speed and velocity of a moving body become identical when it tends to move in a straight line.
The correct answer for the address of the fourth element will be 2225.
The fourth element will be data -.
So if the data[0] element starts at 2222, and each char element takes 1 byte, then
data[0] starts at 2222
data[1] starts at 2223
data[2] starts at 2224
data[3] starts at 2225
Answer: 2225
A linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations is known as an array. Arrays use an index system that ranges from 0 to (n-1), where n is the array's size.
The array data type is a compound data type represented in the database dictionary by the number 8. Arrays are collections of elements of the same data type that are accessed via an index (attribute) number. The terms array, list, vector, and sequence are all synonymous
