The edge effect in habitats are caused by:
A. habitat fragmentation
B. biological magnification
C. eutrophication
D. destruction of habitat
The edge effect in habitats is caused by habitat fragmentation. Therefore, option A is correct.
Habitat fragmentation refers to the process by which large, continuous habitats are divided into smaller, isolated fragments due to human activities or natural events. It occurs when natural landscapes are altered or disrupted. It results in the fragmentation of once-continuous habitats into smaller patches.
This fragmentation can happen through various means, such as the construction of roads, urban development, agriculture, deforestation, or natural events like wildfires or floods.

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)
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

In a nuclear power plant, uranium atoms ______
A. Combine and give off heat energy
B. Split and give of heat energy
C. Burn and give of heat energy
D. Split and give off electrons
Answer:
All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.
i want to now why volcanoes erupt
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.
the total resistance of the circuit
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.

Two parallel plates of area 7.34 x 10^-4 m^2 have 5.83 x 10^-8 C of charge placed on them. A 6.62 x 10^-6 C charge q1 is placed between the plates. What is the magnitude of the electric force on q1? Hint: How is force related to the field? (Unit = N)
Answer:
* if the two plates have the same charge sign F_net = 0
*if one plate is positive and the other is negative F_net = 59.4 N
Explanation:
The electric field created by a parallel plate is
E = [tex]\frac { \sigma }{2 \epsilon_o }[/tex]
where sigma is the charge density
σ = Q / A
we substitute
E = [tex]\frac{Q}{A \ 2 \epsilon_o }[/tex]
E = [tex]\frac{ 5.83 \ 10^{-8} }{7.34 \ 10^{-4}\ 2 \ 8.5 \ 10^{-12} }[/tex]
E = 4.487 10⁶ N / C
the electric force is
F = E / q
in this force it is a vector, so if the charges are of the same sign they repel and if they are of the opposite sign they attract. In this case, the test load is between the two plates that have the same load sign, so the forces are in the opposite direction.
* if the two plates have the same charge sign
F_net = F₁ - F₂
F_net = q (E₁ -E₂)
since the electric field does not depend on the distance
E₁ = E₂
in consecuense
F_net = 0
In a more interesting case
*if one plate is positive and the other is negative
F_net = F₁ + F₂
F_net = q (E₁ + E₂) = 2 q E₁
F_net = 2 6.62 10⁻⁶ 4.487 10⁶
F_net = 59.4 N
net force goes from positive to negative plate

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.
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.

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.
Answer:
D

The potential difference is V=1.743*10^-7
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
V=1.743*10^-7
