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

Answer:

Option B

Explanation:

Given

The current flowing through the circuit = 1 Ampere

As we know

I is inversely proportional to resistance.

I α 1/r

or I = k/r

If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be

I = 1/2 of 1 ampere

I = 0.5 Ampere

Hence, option B is correct

Answer:

E = 0.437 N/C

Explanation:

Given that,

Charge, [tex]q=8\times 10^{-4}\ C[/tex]

Electric force, [tex]F=3.5\times 10^{-4}\ N[/tex]

Let the strength of the electric field is E. We know that, the electric force is given by :

F = qE

Where

E is the electric field strength

[tex]E=\dfrac{F}{q}\\\\E=\dfrac{3.5\times 10^{-4}}{8\times 10^{-4}}\\E=0.437\ N/C[/tex]

So, the strength of the electric field is equal to 0.437 N/C.

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

c. The truck with greater speed

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents speed or velocity measured in metres per seconds square.

From the above formula, we can deduce that the kinetic energy of an object is directly proportional to the square of the value of its velocity or speed.

Hence, the truck with greater speed would have a greater amount of kinetic energy.

Answer:

The trucks will have the same kinetic energy.

Explanation:

Both of the trucks have the same mass, so they have the same kinetic energy. Hope this helps!

Answer:

1. t = 4.24 s

2. [tex]v_{f} = 42.43 m/s [/tex]

Explanation:

Podemos encontrar el tiempo de caída con la siguiente ecuación:

[tex] v_{f} = v_{0} + gt [/tex]   (1)

En donde:

[tex] v_{f}[/tex]: es la velocidad final de la pelota  

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (se deja caer)

g: es la aceleración debida a la gravedad = 10 m/s²

Debemos hallar primero la velocidad final. Podemos usar la ecuación:

[tex] v_{f}^{2} = v_{0}^{2} + 2gh [/tex]  (2)

En donde:

h: es la altura = 90 m

[tex] v_{f} = \sqrt{2gh} = \sqrt{2*10 m/s^{2}*90 m} = 42.43 m/s [/tex]

Entonces, la velocidad con la que la pelota llega al suelo es 42.43 m/s.

Ahora podemos encontar el tiempo que tarda en caer la pelota resolviendo la ecuación (1) para "t":

[tex] t = \frac{v_{f}}{g} = \frac{42.43 m/s}{10 m/s^{2}} = 4.24 s [/tex]

Por lo tanto, la pelota tarda 4.24 segundos en caer.

Answer:

it depends on a person's own weight

Answer:

The gravity is roughly the same. The inverse square law applies to gravity and that means that being 60 miles above Earth is about the same as being on Earth. The thing is, they are going really fast in an orbit and thus falling around the Earth. The weightlessness comes from a sort of cancellation of gravity pulling them down and their going perpendicular to that force. The forces are cancelling and making them relatively “weightless”. It’s not really weightlessness but just an equilibrium reached between the two accelerations of gravity and their motion against the pull of the Earth.

Answer:

Explanation:

Answer:

0,8 m

Explanation:

Recordemos que el potencial eléctrico V se da como

V = q / 4πεod

Dónde;

q = cantidad de carga

εo = permitividad del espacio libre

d = polvo de separación

Pero;

1 / 4πεo = 9 * 10 ^ 9

Entonces;

V = 45 000 V

q = 4x10-6C

 45.000 = 9 * 10 ^ 9 * 4x10-6 / d

d = 9 * 10 ^ 9 * 4x10-6 / 45,000

d = 0,8 m

Answer:

Due to the force of friction

Explanation:

Whenever an object comes in contact with a surface the force of friction comes into play

Which slows down the object (in this case the bowling ball)

Answer:

The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

Answer:

Echo..... when the sound reflects back

Answer:

1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force

Explanation:

A body in a fluid is subjected to two forces, its weight and the thrust

           sun F = B - W

the em

bid is always vertical and contrary to weight, let's analyze and complete the different situations presented

1) Buoyant force

2) sinks           B <W

3) equilibrium B = W

4) fleet             B> W

5) by the sum of two forces:

* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.

* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called   LIFT force
