Answer:
Resistance, R = 2.5 Ohms
Explanation:
Given the following data;
Voltage = 10 V
Current = 4 A
To find the resistance;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Making resistance, R the subject of formula, we have;
[tex] R = \frac {V}{I} [/tex]
Substituting into the equation, we have;
[tex] R = \frac {10}{4} [/tex]
Resistance, R = 2.5 Ohms
Therefore, the resistance of the resistor in the electrical circuit is 2.5 Ohms.

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.

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?

The edge effect in habitats are caused by:
A. habitat fragmentation
B. biological magnification
C. eutrophication
D. destruction of habitat
Answers
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)
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 current through a 12W resistor in an electric circuit is 1.5A. Calculate the potential differences across the resistor
Answers
Answer:
Potential difference = 8 Volts
Explanation:
Given the following data;
Power = 12 Watts
Current = 1.5 A
To find the potential difference;
Power = current * voltage
12 = 1.5 * voltage
Voltage = 12/1.5
Voltage = 8 Volts
Therefore, the potential difference which is the same as voltage is 8 Volts.

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.

A wire carries a current of 6.52 A in a direction that makes an angle of 44.8 degrees with the direction of a magnetic field of strength 0.258 T. What is the magnetic force on a 3.61 m length of wire

Answer:
[tex]F=4.27N[/tex]
Explanation:
From the question we are told that:
Current [tex]I = 6.52 A[/tex]
Angle [tex]\theta= 44.8 \textdegree[/tex]
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

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.
