the plates?
(Unit = V)
pls hurry <3
Answers
Answer:
175
Explanation:
its for Acellus
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.
CALCULATION
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

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.

PLZ Help Me I give you brainlist also NO LONKS OR I REPORT and Have a gr8 day my peeps
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?

Explanation:
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.

A ball is released from a height of 20 metres. Calculate; 1. The time it takes to fall 2. The velocity with which it hits the ground
Answers
Answer:
Final velocity of ball = 20 m/s
Explanation:
Given:
Height when ball released = 20meter
Find;
Time taken to fall
Final velocity of ball
Computation:
Initial velocity of ball = 0 m/s
Acceleration due to gravity = 10 m/s²
Using equation of motion;
S = ut + (1/2)(g)(t²)
20 = (0)(t) + (1/2)(10)(t²)
20 = 5(t²)
(t²) = 20 / 5
(t²) = 4
Time taken to fall = 2 second
V = u + at
V = 0 + (10)(2)
Final velocity of ball = 20 m/s

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.

An incline plane is 12-m long and 4-m high. A block is pulled up the ramp with a spring scale. The reading on the spring scale is 70-N. How many Newtons would the block actually weigh if you had to lift it the 4-m height?
Answers
Answer:
W = 210 N
Explanation:
For an ideal machine:
[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]
where,
P = Effort = Spring Scale Reading = 70 N
L = Effort Arm = Length of inclined plane = 12 m
W = Actual Load (Weight) to be lifted = ?
H = Load Arm = Height = 4 m
Therefore,
[tex](70\ N)(12\ m) = (W)(4\ m)\\\\W = \frac{(70\ N)(12\ m)}{4\ m}[/tex]
W = 210 N

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

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
Answers
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
[tex]F=BIlsin\theta[/tex]
Therefore
[tex]F=0.258*6.52*3.61*sin 44.8[/tex]
[tex]F=4.27N[/tex]

How does the intensity of light change for a location depending on the season?
Answers
Answer:
The intensity of light can change with the time of the day, season, geographic location, distance from the equator, and weather. It gradually increases from sunrise to the middle of the day and then gradually decreases toward sunset; it is high during summer, moderate in spring and fall, and low during winter time.
Explanation:
translational movement with the tilt of the earth's axis we can explain the change in intensity that an area receives determined with the weather station.
In summer the axis points to the sun, which is why more intensity per unit area arrives. In winter the axis moves away from the sun intensity per unit area is less
The intensity of the radiation is defined by the relationship between the power on the irradiated surface
I = P / A
where I is the intensity, P is the power emitted by the sun and A is the area.
The intensity of the radiation that reaches it is around 1400 W / m² in the upper part of the Earth's atmosphere, this amount varies slightly when the planet passes from its furthest point from the sun to its closest point, that is, perihelion to aphelion.
The most important variation of this intensity is due to the fact that it has its axis inclined and the normal to the area changes in relation to the incident radiation during the translational movement around the sun.
In the summer the axis of the earth is inclined towards the sun, so the rays fall more perpendicularly, therefore their absorption over the area is maximum and the temperature rises.
In winter, the earth's axis is tilted away from the sun, so the rays they carry are distributed over a larger surface area and therefore less energy is absorbed per unit area and the temperature decreases.
In the spring and autumn seasons, the Earth's axis is almost vertical, so the absorption is intermediate and the temperature of the Earth is between the two maximums.
Using an analysis of the translational movement with the inclination of the earth's axis, we can explain the change in intensity received by an area determined with the weather station.
