what frequency does television channel 7 broadcast at?
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.

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]
We have the final answer as
19.3 g/cm³Hope this helps you

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.

Calculate the heat that must be supplied to
a 532 , stainless steel vessel containing 375 g
of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.
Also what percentage of the heat is used to raise the temperature of the water?
Answers
Answer:
Q must be supplied = 119523.3~J
Explanation:
The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
So from the question :
Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)

Answer:
Explanation:
Heat transfer occurs by three main mechanisms: conduction, where rigorously vibrating molecules transfer their energy to other molecules with lower energy; convection, in which the bulk movement of a fluid causes currents and eddies that promote mixing and the distribution of thermal energy

When measuring the volume of a liquid, why is it best to use a measuring container that is narrow?
Answers
Answer:
n the sciences, the “tools” for measuring the volumes of liquids are generally made from glass, plastic or occasionally metal, although professionals referred to all of them as “glassware.” Scientists, and chemists in particular, have a variety of glassware at their disposal for measuring volumes. The particular piece of glassware chosen in any situation will depend primarily upon two factors: the required volume and the accuracy required for the measurement.
