What is the average velocity of the object from t=1s to t= 3 s?
A. 1 m/s
B. 0.5 m/s
C. -0.5 m/s
D. -1 m/s
Answers
Answer:
Explanation:
Since this is a distance v time graph, the slope of the line from 1s to 3s is the velocity. However, it looks like, at t=3, the velocity is 0, so getting the definite velocity is not going to happen. We can estimate it as closely as possible. Since the line is tending from the upper left to the lower right, the slope is negative, so the velocity is also negative. That leaves only C or D as our answers. And the slope is closer to -1 than to -5, so choice D. is the one you want.

the total resistance of the circuit
Answers
The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Answer: 3
Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells
Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?

i want to now why volcanoes erupt
Answers
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Explanation:
Explanation:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.
Because cosmic distances are so vast, astronomers use light-years as their unit of distance. One light-year is defined as _______________________. The nearest star is a little more than ____ light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken _______________ to reach us. Light from the Sun takes ___________ to reach us.
Answers
Answer:
Because cosmic disaster are so vast, astronomers use light-years as their unit of distance. One light-year is defined as the distance a beam of light travels in one year. The nearest star is a little more than 4.37 light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken 2 million Earth years to reach us. Light from the Sun takes approximately 8.4269 minutes to reach us
Explanation:
i) One light-year is defined as the distance a light beam travels in a time of one Earth year. One light year is equivalent to 6 × 10¹² miles or 9.7 × 10¹² km
ii) The distance to the nearest star = 4.37 light-years
iii) When a star located in a galaxy that is 2.3 million light years away is seen, it has taken 2.3 million light years to reach us
iv) The distance of the Sun to the Earth = 151.58 million kilometers
The speed of light, c = 299792.458 km/s
The time it will take light to reach us from the Sun, 't', is given as follows;
t = 151.58 × 10⁶ km/(299792.458 km/s) ≈ 8.4269 minutes.
In a certain circuit the number of electrons passing a given point in 3 seconds is 6 x 1014 electrons. What is the current flow in this circuit? (Show all work, including substitution with units)
Answers
Answer:
Current = 0.000032 Amperes
Explanation:
Given the following data;
Time, t = 3 seconds
Number of electrons = 6 * 10^14 electrons
Conversion:
First of all, we would convert the number of electrons to charge.
Coulombs = electron charge ÷ 6.2415 * 10^18
Coulombs = (6 * 10^14) ÷ (6.2415 * 10^18)
Coulombs = 0.000096 Coulombs
To find the current;
Mathematically, quantity of charge is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
0.000096 = current * 3
[tex] Current = \frac {0.000096}{3} [/tex]
Current = 0.000032 Amperes

The voltage is generally referred to as the electric potential difference and it can be measured using a voltmeter. The electrical potential difference between the two plates is expressed as q=CV.

we know,
q=CV
q={EA/d}*V
here q= 5.24*10^-8C
A=8.22*10^-5m^2
d=2.42*10^-8m
therefore , C={( 8.85*10^-12)*(8.22*10^-5)}/(2.42*10^-8)
C=3.006*10^-1
q=CV
q/C=V

.- Una esfera hueca de acero a 28°C tiene un volumen de 0.4 m³, calcular a) ¿qué volumen final tendrá a -6°C en m³ y en litros? B) ¿Cuánto disminuyó su volumen en litros?
Answers
Answer:
Ve respuesta abajo.
Explanation:
Para hacer esto, podemos asumir que la presión es constante, pues es un proceso adiabatico, por tanto se aplica la ley de Charles a presión constante:
V₁/T₁ = V₂/T₂ (1)
De ahí podemos despejar V₂, ya que conocemos las condiciones iniciales de temperatura y volúmen, y la temperatura final:
V₂ = V₁ T₂ / T₁ (2)
Las temperaturas deben estar en grados Kelvin, y solo es cuestión de sumarle 273 al valor de la temperatura dada en °C:
T₁ = 28 + 273 = 301 K
T₂ = -6 + 273 = 267 K
El volúmen podemos pasarlo a litros ahora o al final. En este caso, podemos dejarlo en m³ como está y luego pasarlo a Litros. Resolviendo tenemos:
V₂ = 0.4 * 267 / 301
V₂ = 0.35482 m³Pasando este volumen a Litros, sabiendo que 1 m³ son 1000 L:
V₂ = 0.35482 * 1000
V₂ = 354.82 LFinalmente para saber cuanto disminuyó el volumen en Litros, pasemos el volumen inicial a Litros y luego se hace la resta con el volumen final:
V₁ = 0.4 * 1000 = 400 L
V₁ - V₂ = 400 - 354.82
V₁ - V₂ = 45.18 LEsto es lo que disminuyó. Espero te ayude.

Based on the information in the graph, why is energy released during the fusion of hydrogen (H) into helium (He)?
A. The hydrogen-1 nuclei (H - 1) are more stable than the helium-4 (He - 4) nucleus is, because they have less binding energy per nucleon than the helium has.
B. There are fewer nucleons in a helium-4 (He-4) nucleus than there are in four hydrogen-1 (H - 1) nuclei, so there is more energy released per nucleon when helium forms.
C. The hydrogen (H) nuclei are lower in energy than the helium (He) nucleus is, so more energy is stored in a helium nucleus.
D. The helium (He) nucleus is more stable than the hydrogen (H) nuclei are, because more mass is converted into binding energy in helium.

Magnetic field [tex]B= 0.258 T.[/tex]
Length [tex]l=3.61m[/tex]
Generally the equation for Magnetic force F is mathematically given by
