An object starts from rest and exhibits the motion represented by the graph. The object’s average velocity during the 3 second to 5 second time interval is approximately –
8.4 m/s
3.2 m/s
4.8 m/s
.0125 m/s
Answers
Answer:
8.4 m/s
Explanation:
Initial velocity of the object is 0 as it was at rest.
We need to find the object’s average velocity during the 3 second to 5 second.
We can see from the graph that from 3 s to 5 s, the graph is a straight line. If we take the slope we can find the average velocity during the 3 second to 5 second.
Displacement between 3 s to 5 s is :
D = 24.8 m - 8 m = 16.8 m
Time = 5 s - 3 s = 2 s
Now,
Average velocity,
[tex]v=\dfrac{\Delta y}{\Delta x}\\\\y=\dfrac{16.8\ m}{2\ m}\\\\y=8.4\ m[/tex]
So, the object’s average velocity during the 3 second to 5 second is 8.4 m/s.

A 57.9 gram mass has a volume of 3 cm 3. What is the density of the mass?
Answers
Answer:
The answer is 19.3 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume}\\[/tex]
From the question
mass = 57.9 g
volume = 3 cm³
We have
[tex]density = \frac{57.9}{3} \\ [/tex]

The atomic mass of Gallium is 69.72 AMU. The masses of the naturally occurring isotopes are 68.9257 AMU and 70.908 AMU for Ga-69 and Ga-71. Find the percent (%) abundance for each.
Answers
Answer:
40.7% abundance of Ga-71
59.93% abundance of Ga-69
Explanation:
Given data:
Average atomic mass of Ga = 69.72 amu
Atomic mass of Ga-69 = 68.9257 amu
Atomic mass of Ga-71 = 70.908 amu
Percent abundance of each isotope = ?
Solution;
we know there are two naturally occurring isotopes of Ga.
First of all we will set the fraction for both isotopes
X for the isotopes having mass 68.9257
1-x for isotopes having mass 70.908
we will use the following equation,
68.9257x + 70.908 (1-x) = 69.72
68.9257x +70.908 - 70.908x = 69.72
68.9257x - 70.908x = 69.72 - 70.908
-1.9823x = - 1.188
x= 1.188/1.9823
x= 0.5993
0.5993 × 100 = 59.93 %
59.93 % is abundance of Ga-69 because we solve the fraction x.
now we will calculate the abundance of Ga-71.
(1-x)
1 - 0.5993 = 0.4007
0.4007× 100= 40.7 %
40.7 % for Ga-71.

Genes remove the environmental factors that affect the growth of an organism.
Answers
Answer: The combination of genes and environmental factors affects the growth of an organism.
Explanation:
Gene consists of DNA and it's heredity physical and functional unit. Genes play a vital role in a organisms growth. For example in humans, if one's parents are tall, there's a large tendency that such child will be tall and vice versa.
Environmental temperature also affects growth of living organisms. These include water soil pH, temperature, gender, chemicals etc. These all affects growth, it should be noted that proteins in living organisms can be damaged at a certain temperature which invariably affects the growth of such organism.
Also, the environment influences gene expressions as temperature, light, drugs, and chemicals, affects genes as they determine which ones will either be turned on or off which will further lead to how such organism grows.

Answers
Answer:
Channel 7's frequency is 117.5 MHz
Answer:
174 MHz - 180 MHz w/ center frequency of 177 MHz
Explanation:
216 - 174 = 42
42/7 = 6
6 + 174 = 180 - 7 - 177 MHz
180 + 6 = 186 - 8 - 183 MHz
186 + 6 = 192 - 9 - 189 MHz
192 + 6 = 198 - 10 - 195 MHz
198 + 6 = 204 - 11 - 201 MHz
204 + 6 = 210 - 12 - 207 MHz
210 + 6 = 216 - 13 - 213 MHz

Water is a pure substance. Which of the following is true about water?
a
A chemical change is required to separate the elements present in it.
b
A physical change is required to separate the elements present in it.
c
It is made up of two compounds, each with a different set of atoms.
d
It is made up of an element and a compound.
Answers
Answer:
A chemical change is required to separate the elements present in it.
Explanation:
The only true statement from the choices given is that water as a pure substance requires a chemical change to separate the elements present in it.
Water is a molecule consist of two atoms of hydrogen and one atom of oxygen.
The atoms are covalently bonded together. A chemical process, the electrolysis of water is often used to separate the atoms of a water. Physical changes cannot be used to separate the atoms of water. Water is a compound which consists of two elements.Therefore, we see that only the first choice satisfies this problem.

Which of these particles is the smallest?
A.a proton
B.a nucleus
C.an electron
D.an atom
Answers
Answer:
an atom. It is the smallest thing known to man kind
Explanation:
Answer:
C
Explanation:
so basically, we can eliminate some answer choices right away.
an atom (answer choice D) is made up of all the other answer choices, so that is the largest (not the answer).
a nucleus (answer choice B) is made up of protons (answer choice A) and neutrons which means it is not the smallest either (not the answer).
now, we are left with a proton and an electron. electrons are much smaller than protons, so they are usually not included in an element's atomic mass. therefore, an electron is the smallest out of these answer choices.
