a. 4N
b. 9N
C. 12 N
d. 18 N
Answer:
The force will be cut in half also so the new force will be 18 N (d).
Astronomers categorize galaxies into a handful of basic shapes. What can you conclude from this fact?
From the that astronomers categorize galaxies into a handful of basic shapes, it can be concluded that the all galaxies are made from the same forces.
Astronomers have categorized galaxies into three main categories,
Elliptical Galaxies:
These galaxies have smooth ellipsoidal shape. They are most abundant type. For example- Messier 49
Spiral galaxies:
These galaxies have a spiral shapes with many hand like structures. For example- Milky way.
Irregular Galaxies:
They do not have any specific shape.

A set of charged plates have an
area of 8.22*10^-4 m^2 and
separation 2.42*10^-5 m. The
plates are charged with
5.24*10^-8 C. What is the
potential difference V between
the plates?
(Unit = V)
pls hurry <3
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

A student shakes the end of
a rope
with
frequency of 1.5 Hz, causing waves with a
wavelength of 0.8 m to travel along the rope.
What is the velocity of the waves?
Answer:
1.2m/s
hope this helps!
The required velocity of the waves is 1.2 meters per second.
What is wavelength?Wavelength is a fundamental property of waves, including electromagnetic waves like light and radio waves, as well as other types of waves, such as sound waves or water waves.
Here,
The velocity of a wave can be calculated using the equation:
Velocity = frequency × wavelength
In this case, the frequency is 1.5 Hz and the wavelength is 0.8 m. Therefore, the velocity of the waves is,
Velocity = 1.5 Hz × 0.8 m = 1.2 m/s
So the velocity of the waves is 1.2 meters per second.

Sound travels at about 360 meters/sec. What is the wavelength of sound with a
frequency of 1500 Hz?
Answer:
0.24 m
Explanation:
Given:
Wave velocity ( v ) = 360 m / sec
Frequency ( f ) = 1500 Hz
We have to calculate wavelength ( λ ):
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > λ = v / f
Putting values here we get:
= > λ = 360 / 1500 m
= > λ = 36 / 150 m
= > λ = 0.24 m
Hence, wavelength of sound is 0.24 m.

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.

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.
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

How many moles of gas are in a 34.2 L container at 1 atm of pressure and 123℉?
How many moles of gas are in a 22.4 L container at 1 atm of pressure and 89℃?
How many moles of gas are in a 16.7 L container at 1 atm of pressure and 273.15 K?
Answer:
1.29 moles
0.753 moles
0.745 moles
Explanation:
PV=nRT
n=PV/RT
n=(1)(34.2)/(0.0821)(323.7)
n=1.29
n=PV/RT
n=(1)(22.4)=(0.0821)(362.15)
n=0.753
n=PV/RT
n=(1)(16.7)/(0.0821)(273.15)
n=0.745

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.

A 6,600 kg train car moving at +2.0 m/s bumps into and locks together with one of mass 5,400 kg moving at −3.0 m/s . What is their final velocity?
−1.0 m/s
−0.25 m/s
+0.50 m/s
+2.5 m/s
Answer:
option B is the correct option
Explanation:
According to momentum conversion,
momentum of one car= 6600×2=13,200kgm/s
momentum of another car=5,400×(-3)=16,200kgm/s
Then,
Momentum of second car-momentum of first car
=16,200-13200
=3000kgm/s
mass of first car -mass of second car
=6600-5400
=600kg
final velocity=3000/600=2.5 m/s
