Answer:
so what do we need to do
Explanation:
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?
Answer:
Following are the responses to the given choices:
Explanation:
The maximum pressure is 10 V from across condenser.
The highest charge mostly on condenser.
[tex]vc = 10\times 1\ mf\\\\[/tex]
[tex]= 10^{-5}\ C[/tex]
The time it takes for the condenser to be 5 V different.
[tex]time = ln_2 \times 1000 \times 1mf[/tex]
[tex]=0 .69 \times 10^{-3}\ sec[/tex]
How are wave properties and energy related?
EXPLAIN
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.

Why does an aircraft carrier float
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
A Normal force of 16N is distributed uniformly on top surface of a cube of edge 6cm. The
pressure on this surface is Rx104Pa. Find the value of R
Answer:
approx. 0.43
Explanation:
Area of the side of the cube is 36 cm or 0.36 m, P= F/A, so R*104=16/0.36, R*104≅44.44, R≅0.43

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

Answer:
Due to the force of friction
Explanation:

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
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
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
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!

There is a fixed voltage across a resistor, and you measure a current of c1 A. If you replace the resistor with one that has twice the resistance value, how much current will you measure? a) 0.2 A b) 0.5 A c) 0.8 A d) 1.1 A
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

A positive charge of 8.0 × 10-4 C is in an electric field that exerts a force of 3.5 × 10-4 N on it. What is the strength of the electric field?
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.
