Can sugar molecules produced from photosynthesis be rearranged into different compounds carry out life process
Answer:
Yes, the sugar molecules produced from photosynthesis can be rearranged into different compounds to carry out life processes such energy producing compounds, energy storage compounds, body building compounds, and compounds of other types of food
Explanation:
a) The sugar can be broken down in a plant cell to produce ATP and then energy through cellular respiration as follows;
C₆H₁₂O₆ + O₂ 6CO₂ + 6H₂O + ATP
The produced energy can be used as power for cellular activities, such as the synthesis of protein and cell division
b) The produced sugar can be linked together by enzymes to form starch which is a form of chemical storage of energy as follows;
Sugar C₆H₁₂O₆ transformed into starch (C₆H₁₀O₅)ₙ
c) The sugar can be used in building the plant body by forming cellulose which is a form of starch
d) The sugar can be transformed into proteins and fat which are other types of food such as compounds containing sugar produces compounds containing fat based compounds

Un vehiculo se desplaza con movimiento rectilio uniforme. Sabiendo que recorre 90 km en 3 horas. Averiguo la velocidad en m/s.
Answer:
Velocidad = 500 m/s
Explanation:
Dados los siguientes datos;
Distancia = 90 km
Tiempo = 3 horas
Conversión;
Por distancia:
1 kilómetro = 1000 metros
90 kilómetros = 90 * 1000 = 90,000 metros
Para el tiempo:
1 hora = 60 segundos
3 horas = 60 * 3 = 180 segundos
Para encontrar la velocidad en m/s;
Matemáticamente, la velocidad viene dada por la ecuación;
[tex] Velocidad = \frac {distancia} {tiempo} [/tex]
Sustituyendo en la fórmula, tenemos;
Velocidad = 90000/180
Velocidad = 500 m/s
Sodium has an atomic mass of 23 and an atomic number of 11, so the
number of neutrons must be_______
Answer here
Answer:
12 Neutrons
Explanation:
So the mass of sodium is 22.990. You round it up to get 23(as stated in the problem). So, what exactly is atomic mass?
Atomic Mass is the total amount of neutrons and protons added up to form a total mass. So when you subtract 23-11 you get 12 Neutrons.
Tip: Don't know if you need this but-
The neutrons and protons are typically close in number (unless it's an isotope). So say that you subtract and the numbers of protons and neutrons aren't close at all. Well if that's the case, it's probably wrong.

three resistors of 20. ohms, 30. ohms, and 60. ohms, respectively, are connected in series with a battery. a current of 2.0 amperes will flow through this circuit when the potential difference of the battery is a. 20.V b. 220 V c. 110 V d. 10.V.
Answer:
b. 220 V
Explanation:
Let resistors be R1, R2, and R3 respectively.
Given the following data;
R1 = 20 ohms
R2 = 30 ohms
R3 = 60 ohms
Current = 2 Amperes
To find the voltage;
First of all, we would determine the total effective resistance (RT).
For series circuit;
RT = R1 + R2 + R3
RT = 20 + 30 + 60
RT = 110 Ohms
Next, we find the voltage using the formula;
Voltage = current * resistance
Voltage = 2 * 110
Voltage = 220 Volts
Hi, I'm stuck on the problem: Consider a resistor (R=1000 kΩ) and a capacitor (C=1μF) connected in series. This configuration is connected in series to a battery with an emf of 10 V. Find the maximum voltage in [V] across the capacitor. Find the maximum charge on the capacitor in [µC]. How long will it take until the capacitor has a potential difference of 5 V?

Two vehicles A and B accelerate uniformly from rest.
Vehicle A attains a maximum velocity of 30ms - in los
while B attains a maximum velocil) ol 40ms in the same
time. Both vehicles maintain these velocities for 6s belore
they are decelerated to rest in 6s and 4s respectively
Sketch on the same axes, velocity time graphs
for the motion of the vehicles
Calculate the velocity of each vehicle 18s aftur
the start. (VA
= 20ms -land vs
and vs = 20ms-')
How far will the two vehicles be from one
another during the moment in (ii) above?
(SA = 380m and SB
= 500m: SAB
120m). plz help
Answer:
(i) Please find attached the required velocity time graphs plotted with MS Excel
(ii) The velocity of vehicle A at the 18th second = 20 m/s
The velocity of vehicle B at the 18th second = 0 m/s
(iii) The distance between the two vehicles at the moment in (ii) above is 60 meters
Explanation:
The given parameters of the motion of vehicles A and B are;
The acceleration of vehicles A and B = Uniform acceleration starting from rest
The maximum velocity attained by vehicle A = 30 m/s
The time it takes vehicle A to attain maximum velocity = 10 s
The maximum velocity attained by vehicle B = 30 m/s
The time it takes vehicle B to attain maximum velocity = The time it takes vehicle A to attain maximum velocity = 10 s
The time duration vehicle A maintains its maximum velocity = 6 s
The time duration vehicle B maintains its maximum velocity = 4 s
(i) From the question, we get the following table;
[tex]\begin{array}{ccc}Time &V_A&V_B\\0&0&0\\10&30&40\\14&30&40\\16&30&20\\18&20&0\\22&0&\end{array}[/tex]
From the above table the velocity time graphs of vehicles A and B is created with MS Excel and can included here
(ii) The velocity of vehicle A at the start = 0 m/s
After accelerating for 10 seconds, the velocity of vehicle A = The maximum velocity of vehicle A = 30 m/s
The maximum velocity is maintained for 6 seconds which gives;
At 10 s + 6 s = 16 s, the velocity of vehicle A = 30 m/s
The time it takes vehicle A to decelerate to rest = 6 s
The deceleration of vehicle A, [tex]a_A[/tex] = (30 m/s - 0 m/s)/(6 s) = 5 m/s²
Therefore, we get;
v = u - [tex]a_A[/tex]·t
At the 18th second, the deceleration time, t = 18 s - 16 s = 2 s
u = 30 m/s
∴ v₁₈ = 30 - 5 × 2 = 20
The velocity of vehicle A at the 18th second, [tex]V_{18A}[/tex] = 20 m/s
For vehicle B, we have;
At the 14th second, the velocity of vehicle B = 40 m/s
Vehicle B decelerates to rest in, t = 4 s
The deceleration of vehicle B, [tex]a_B[/tex] = (40 m/s - 0 m/s)/(4 s) = 10 m/s²
For vehicle B, at the 18th second, t = 18 s - 14 s = 4 s
∴ [tex]v_{18B}[/tex] = 40 m/s - 10 m/s² × 4 s = 0 m/s
The velocity of the vehicle B at 18th second, [tex]v_{18B}[/tex] = 0 m/s
(iii) The distance covered by vehicle A up to the 18th second is given by the area under the velocity-time graph as follows;
The area triangle A₁ = (1/2) × 10 × 30 = 150
Area of rectangle, A₂ = 6 × 30 = 180
Area of trapezoid, A₃ = (1/2) × (30 + 20) × 2 = 50
The distance covered in the 18th second by vehicle [tex]S_A[/tex] = A₁ + A₂ + A₃
∴ [tex]S_A[/tex] = 150 + 180 + 50 = 380
The distance covered in the 18th second by vehicle [tex]S_A[/tex] = 380 m
The distance covered by the vehicle B in the 18th second is given by the area under the velocity time graph of vehicle B as follows;
Area of trapezoid, A₅ = (1/2) × (18 + 4) × 40 = 440
The distance covered by the trapezoid, [tex]S_B[/tex] = 440 m
The distance of the two vehicles apart at the 18t second, [tex]S_{AB}[/tex] = [tex]S_B[/tex] - [tex]S_A[/tex]
∴ [tex]S_{AB}[/tex] = 440 m - 380 m = 60 m
The distance of the two vehicles from one another at the 18th second, [tex]S_{AB}[/tex] = 60 m.
