Two ways I can decrease the force attraction between two charged objects?
Answer: Change distance and charge
Explanation:
Increase the distance between the two particles, and remove charge from one or more of the particles.
Coulomb's Law is:
[tex]F=\frac{kq_1q_2}{r^2 }[/tex]
k being a constant of 8.99 x 10^9 (units)
q1 and q2 being the magnitude of charges
r being the distance between them

2. What type of signals does the nervous system send? What carries these signals
Answer:
Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10 2 T acting at
right angles to the wire of length 19 m and current of 0.043 A? Round your answer to 2 significant
figures.
Answer:
2900 N
Explanation:
We are given;
Magnetic flux density; B = 3.6 × 10² T
Length of wire; L = 19 m
Current; I = 0.043 A
Formula for force in this regards is;
F = BIL
Where;
B is Magnetic flux density
I is current
L is length
Thus;
F = 3.6 × 10² × 0.043 × 19
F = 2941.2
To 2 significant figures gives;
F = 2900 N
The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical
rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.
Answer: Boat P
Explanation:
Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436
The minimum time taken to unwind the rubberband is by boat P.
The highest amount of force to unwind the rubberband is generated by boat P.
Force, Mass and AccelerationThe table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.
Force = Mass [tex]\times[/tex] Acceleration
For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]
For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]
For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]
For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]
Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

Which waves have oscillations parallel to their direction of motion
Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.
Explanation:
The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.
What are sound waves?A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.
Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

All music, _______ in the world, is from only ______ notes.
Answer:
All music in the world, is form only two notes and those notes are described below in detailed explanation.
Explanation:
In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.
Varieties Of Musical Notes You Require To Understand
Semibreve (Whole Note)
Minim (Half Note)
Crotchet (Quarter Note)
All music, listened to in the world, is from only twelve (12) notes.
A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.
A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.
Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.
This ultimately implies that, any musical piece that you may have come across in this world comprises only twelve (12) notes and these include:

6. Dentists use a soft, clay-like material to make a filling for a cavity. The filling stays soft under the
light of the dentist's lamp, but it hardens when the dentist shines an ultraviolet flashlight on it. Why
does light from the ultraviolet flashlight harden the filling when light from the lamp does not?
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.
What is ultravoilet ray?Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.
Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,
Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.
