El potencial electrico debido a una carga en un punto P es de 45 000 V. Si la magnitud de la carga es 4x10-6C. A que distancia esta el punto P de la cartga

Answers

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

Two trucks have the same mass. Which truck will have a greater amount of kinetic energy? b. The truck with less mass d. The trucks will have the same kinetic energy c. The truck with greater speed a. The truck with more mass​

Answers

Answer:

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!

Can sugar molecules produced from photosynthesis be rearranged into different compounds carry out life process

Answers

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.

Answers

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

Answers

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.
