what is the movement of energy by waves
Answer; thermal energy
Explanation:
'Wave' is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
what does chucking do for your memory
Answer:
By separating disparate individual elements into larger blocks, information becomes easier to retain and recall. This is due mainly to how limited our short-term memory can be. ... Chunking allows people to take smaller bits of information and combine them into more meaningful, and therefore more memorable, wholes.

element that
draws a current of 2 A?
Answer:
100 V
Explanation:
Hi there!
Ohm's law states that [tex]V=IR[/tex] where V is the voltage, I is the current and R is the resistance.
Plug the given information into Ohm's law (R=50, I=A)
[tex]V=IR\\V=(2)(50)\\V=100[/tex]
Therefore, the voltage across this current is 100 V.

In free fall, where does an object have the slowest speed? *
O Vi
O vf
Vtop
O more than one is correct
Answer:
vi and vtop = 0
Explanation:
Free fall is a motion of a body in which the only force acting of the body is the Gravitational Force. In this motion body moves with constant acceleration i.e acceleration due to gravity.
When an object is thrown downward from a non zero height say h the motion is referred to as free fall with initial velocity of object beign zero. Hence v=0
In free fall, an object have the slowest speed at the beginning of the motion which is at the top before the object starts to fall. [tex](V_i \ and \ V_{top})[/tex]
During a free fall, the object subjected to only acceleration due to gravity. The velocity of object increases as the object moves downwards and eventually becomes maximum before the object hits the ground.
The final velocity of the object is the greatest while the initial velocity of the object at the top before the free fall is the slowest.
[tex]V_f > V_i \ or\ V_{top}[/tex]
Thus, we can conclude that during a free fall, the velocity of the object increases downwards. The slowest speed can found at the beginning of the motion.

A block is pulled
7.00 meters along a
horizontal
surfacewith a
constant 30.0
newton force.
Calculate the
workdone on the
block.
The work done by the force for pulling a block till 7 meter along horizontal direction by using force of 30 N is, 210 joules.
What is work ?In physics, the work is defined as product of Force in the direction motion into distance travelled.
The work done on the block is given by the formula:
Work = Force x Distance x Cos(θ)
where Force is the force applied on the block, Distance is the distance the block is moved, and θ is the angle between the force and the direction of motion.
Given that,
F = 30 N
Distance = 7 m
W = ?
The force is constant and the surface is horizontal,
so the angle θ is equal to 0°, and cos(0°) is equal to 1.
Therefore, the work done on the block can be calculated as:
Work = Force x Distance x Cos(θ)
= 30.0 N x 7.00 m x 1
= 210 J
So, the work done on the block is 210 Joules.

Answer:
Explanation:
A 4.0 kg mass has a velocity of 10 m/s to the EAST. The 4.0 kg mass is subjected to a constant net force of 16 N to the WEST for 3.0 sec. What is the velocity of the 4.0 kg mass at the end of the 3.0 sec interval?
The final velocity of the 4.0 kg mass is equal to 22 m/s.
What is Newton's second law of motion?According to Newton’s second law of motion, the force acting on the object equals the mass of that object times its acceleration for a constant mass.
The acceleration of an object depends on two variables, one is the mass of the object and another is the net force acting. The acceleration of an object is directly proportional to the force acting on the body and inversely proportional to its mass.
The equation of Newton’s second law can be represented as follows:
F = ma
or, a = F/m
Given, the initial velocity of the mass, u = 10m/s
The mass, m = 4.0 Kg
The force acting on the mass, F = 16 N
The acceleration of the mass will be: a = F/m
a = 16/4 = 4 m/s²
From the 1st equation of motion: v = u + at
The velocity after t = 3 sec can be calculated:
v = (10) + (4) × (3)
v = 10 + 12
v = 22 m/s

Answer:
Slipher developed spectrographic methods that allowed researchers to see a Doppler effect in the distances of what were then called “spiral nebula,” what we today call galaxies. Simply put, by measuring the longer wavelength red shift (objects moving away) and shorter wavelength blue shift (objects moving closer), Slipher demonstrated that the universe was not static.

How to write the formula for water
explain why when water is poured on a dry class slab it spreads uniformly but it forms spherical droplets on a waxed glass slab
Answer and Explanation:
The texture of the slabs affects the type of bonding the water molecules has with each other.
The dry glass slab allows the water to form cohesive bonds with each other, making the water stick to itself and not the slab, which makes it flow uniformly, or regularly.
The Waxed glass slab has a different texture that forms an adhesive-type bonding with water, making the water stick to the slab at certain parts/forming the spherical droplets.

A piano tuner detects 3 beats per second when she is tuning a string to a tuning fork of frequency 440 Hz. When she tightens the string, which increases the frequency of the string, the frequency of the beats initially goes down, and as she keeps increasing the frequency of the string, the frequency of the beats starts to increase. What was the original frequency of the string
Answer:
[tex]F_o=437Hz[/tex]
Explanation:
From the question we are told that:
Frequency of Turning fork [tex]F_t=440Hz[/tex]
Number of beats detected [tex]n=3[/tex]
Generally the equation for Original frequency [tex]F_o[/tex] of the string is mathematically given by
[tex]F_o=F_t-F_b[/tex]
Where
[tex]F_b[/tex] Beat frequency
[tex]F_b=1Hz*n\\F_b=1Hz*3[/tex]
Therefore
[tex]F_o=440-3[/tex]
[tex]F_o=437Hz[/tex]
