Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
I pushed a 2 kg car with an 8 N force. Calculate the acceleration.
Answer:
4 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{8}{2} \\ [/tex]
We have the final answer as
4 m/s²Hope this helps you

What is the affected variable in an experiment. A:independent. B:dependent. C:control
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

What causes metal atoms to form metallic bonds?
Answer:
Metallic bond, force that holds atoms together in a metallic substance. ... The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.

What is the speed of an object that covers 10 miles in 5 hours?
a. 5 mph
b. 15 mph
c. 2 mph
d. 50 mph
Answer:
2 miles per hour.
Explanation:
10/5=2
To solve this we must be knowing each and every concept related to speed and its calculations. Therefore, the correct option is option C.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction.
The Scientific unit system is most typically used to express speed. Speed is determined in metres per second, or m/s, since distance is recorded in metres while time is recorded in seconds.
Mathematically,
speed= distance/ time
distance= 10 miles
time= 5 hours
substituting all the given values in the above equation, we get
speed=10/5
on calculations, we get
speed = 2 mph
Therefore, the correct option is option C.

How long would it take a current of 10A to deposit 6.36g of copper during the electrolysis of copper (ll) tetraoxosulphate VI solution. (Cu = 63.5,1F=96500C)
Cu2+ + 2e- Cu
It take 0.54 hours to deposit 6.36g of copper
Further explanationFaraday's Law I
"The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis
W = e.i.t / 96500
[tex]\tt \large {\boxed {\bold {W \: = \: \dfrac {e \times i \: x \: t} {96500}}}}[/tex]
e = equivalent = Ar / valence
i = current, A
t = time, s
W=6.36 g
e = 63.5 : 2 =31.75
i = 10 A
[tex]\tt t=\dfrac{W\times 96500}{e.i}\\\\t=\dfrac{6.36\times 96500}{31.75\times 10 }\\\\t=1933.04~s\approx 0.54~hours[/tex]

What type of reaction does each of the following equations represent?
A. Single replacement
B. Double replacement
C. Decomposition
Answer:
Option C. Decomposition
Explanation:
To know which option is correct, it is important we know what is a single displacement reaction, double displacement reaction and decomposition reaction.
A Single displacement reaction can be defined as a reaction in which a single element is replaced by another element in a compound.
A double displacement reaction is a reaction involving the exchange of ions of two parts of ionic compounds to form two different compounds.
A decomposition reaction is a reaction in which a compound splits into two or more simpler compound or element.
Bearing the above definitions in mind and considering the question given above, we can conclude that the reaction given in the question above is a decomposition reaction since the compound (NH₄OH) splits into two different compound (NH₃ and H₂O)

Which of the following transports electricity between objects in a circuit?
Battery
Light bulb
Switch
Wire
Answer:
Wire.
Explanation:
The wire has movable electrons, which moves the charge and the electricity around.
Battery provides the electricity by electrical potential energy, not transport it.
The switch toggles between an open circuit and a closed one, where only the closed one has a full loop of wire to transport electricity.
And the light bulb uses electricity.

Answer:
Mass of O = 8.2 gram
Explanation:
Given:
Mass of Fe = 10 g
Total volume = 18.2 g
Find:
Mass of O
Computation:
Using Conservation of total mass
Total volume = Mass of O + Mass of Fe
