Answer:
Blue
Explanation:
The colors of the rainbow are known by the acronym; ROYGBIV.
This is;
Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
From research, their respective wavelengths on the average are;
Red: 665 nm
Orange; 630 nm
Yellow; 600 nm
Green; 550 nm
Blue; 470 nm
Indigo; from 445nm to 464 nm
Violet; less than 400 nm
This means that from Red to Violet in that order, wavelength is decreasing in a descending order.
Now in refraction, the light with shortest wavelength will be bent the most while that with longest wavelength will be bent the least.
Thus, violet bends the most.
However, violet is not included in the options. So the next one that will bend the most after violet among the options given is Blue.

Explanation:
An object has 22.4 kg•m/s of
momentum. If you double the mass,
and cut the velocity in half, how
much momentum would it have?
[?] kg•m/s
Answers
Answer:
[tex]22.4\:\mathrm{kg\cdot m/s}[/tex]
Explanation:
Momentum is given by [tex]p=mv[/tex].
Let [tex]p_1[/tex] be the initial momentum of the object:
[tex]p_1=m\cdot v=22.4[/tex]
If we doubled the mass, the new mass would be [tex]2\cdot m[/tex], and if we halved the velocity, the new velocity would be [tex]\frac{1}{2}\cdot v[/tex].
Therefore, the final momentum would be:
[tex]p_f=2\cdot m\cdot \frac{1}{2}\cdot v=m\cdot v=\fbox{$22.4\:\mathrm{kg\cdot m/s}$}[/tex]..

Answers
Answer:
1560.1g or 1.56kg
Explanation:
We are to find the mass of 15.9moles of sulfuric acid.
Sulfuric acid is given as H₂SO₄;
To solve this problem, we convert the mole to mass;
Mass of sulfuric = number of moles x molar mass
Molar mass of H₂SO₄ = 2(1.01) + 32.1 + 4(16) = 98.12g/mol
Mass of sulfuric acid = 15.9moles x 98.12g/moles = 1560.1g or 1.56kg

What is Traffic?Traffic is made up of people using public ways (roadways) for movement, such as walkers, cars, trains, and animals being ridden or herded.
The road rules include traffic rules and unwritten guidelines that may have evolved through time to help ensure the timely and orderly flow of traffic. Traffic laws control and regulate traffic. In general, organized traffic has lanes, right-of-ways, priorities, and intersection traffic control.
In many jurisdictions, traffic is formally structured with designated lanes, junctions, intersections, junctions, traffic signals, or signage.
The three main categories of traffic are heavy motor vehicles, other vehicles, and pedestrians. Speed restrictions and easements may be shared by different classes, or they may be segregated.
Therefore, an alert driver must be able to react as per the other drivers, so it can prevent any mishappening.

You need to calibrate your giant paintball bazooka, so you're fired at an angle of 60° and you find that the giant paintball splatter the ground at a horizontal distance of 107m from the end of the muscle in a distance of 1.7 M below the end of the muzzle. What is the muzzle velocity, V0, of your giant paint ball bazooka?
Answers
Answer:
Vx = V0 cos 60 = V0 ./ 2 horizontal speed
Vy = V0 sin 69 = V0 * .866 = .866 V0 vertical speed
t = 107 / Vx = 214 / V0 time to travel 107 m
h = Vy t - 1/2 * g t*2 time to fall 1.7 m
-1.7 = .866 V0 * 214 / V0 - 4.9 * (214 / V0)^2 substituting
224400 / V0^2 = 187
V0 = (224400 / 187)^1/2 = 2=34.64 m/s
t = 214 / 34.64 = 6.178 stc
Check: h = Vy t - 1/2 g t^2
-1.7 = .866 * 34.64 * 6.178 - 4.9 * 6.178^2
-1.7 = -1.69

Jen is conducting an experiment involving a device known as a pith-ball electroscope, shown below.
The plastic ball of the electroscope hangs in midair and is uncharged. Charges cannot move along the silk thread that holds the ball in the air.
Jen completes the following steps in her experiment:
1- She collects three identical, uncharged rubber tubes.
2-She holds a magnet to the first tube for 5 minutes.
3-She submerges the second tube in a tank of water for 5 minutes.
4- She rubs the third tube with animal fur for 5 minutes.
Jen's teacher tells her that she can use the pith-ball electroscope to see if any of the rubber tubes are surrounded by an electric field. What should Jen do to test for an electric field surrounding each tube?
Answers
Answer:
bring each tube close to the plastic ball and note any movement of the ball
Explanation:
study island
just took the test!!!!!
Answer:
bring each tube close to the plastic ball and note any movement of the ball
Explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.
Since the plastic ball of the electroscope is made of insulating plastic and is uncharged, it will be attracted to any charged object brought near it. So Jen can observe the effects of the tube's electric fields by bringing each tube close to the plastic ball and noting any movement of the ball. If the ball moves toward a tube, then the process that Jen used on the tube generated an electric field.
A 6.50 meter high cylinder is filled with alcohol(density =806 kg/m^3). What is the pressure at the bottom of the cylinder?
Answers
Answer:
152642.2
Explanation:
the pressure at the bottom of the cylinder is
P = Po + rho gh
=101300+806(9.8)(6.5)
=152642.2 Pa
The pressure at the bottom of the cylinder is 152642.2 Pa
What's pressure?If the density of the liquid is ρ then the burden of the liquid inside the first cylinder is W1=ρh1S1g and the strain at the bottom of the primary cylinder (neglecting atmospheric strain) is P1=W1/S1=ρh1g.
Stress, inside the physical sciences, is the perpendicular force according to unit location, or the strain at a point inside a confined fluid.

A rolling ball with a mass of 1.01 kg crashes into a wall. The wall exerts a force of 2.40 Newtons and stops the ball. What was the magnitude of the acceleration of the ball at the time of the crash?
Answers
Answer:
Acceleration, a = 2.38m/s²
Explanation:
Given the following data;
Mass = 1.01 kg
Force = 2.4N
To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force.m represents the mass of an object.a represents acceleration.Making acceleration (a) the subject, we have;
[tex]Acceleration, a = \frac{F}{m}[/tex]
Substituting into the equation, we have;
[tex]Acceleration, a = \frac{2.4}{1.01}[/tex]
Acceleration, a = 2.38m/s²
Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square.

Which of the following is true about myelin?
It inhibits neural communication.
O It cannot be affected by illness.
It is covered by axons.
It's a fatty insulation.
It slows down neuronal operations.
Answers
Answer:
It's a fatty insulation.
Explanation:
"Myelin" is a fatty substance which insulates the axons of the nerve cells. Therefore, it covers the axons. This makes choice A correct and choice C incorrect.
This allows faster neural communication or hastens the transmission of signals between neurons. This makes choice A incorrect and choice E incorrect. It doesn't inhibit neural communication nor does it slow down neuronal operation; rather, it increases both speed.
Myelin can be affected by illness. An example of this is the disease called "Multiple Sclerosis," which targets the myelin sheath.
When are force and acceleration at their minimum in simple harmonic motion?
Answers
Answer:
Since F = M a force and acceleration both have maximum and minimum values at the same point in their motion.
Also, F = - k x where x is the extension of the displacement that creates the acceleration.
Since, there is no force acting on the object at the midpoint of the motion, then F = - k x = 0 and there is no acceleration.
Likewise, at maximum extension F = - k x is a maximum and both the force and acceleration have their maximum values at maximum extension.
what should be angle between force and displacement to get the maximum work
Answers
Answer:
0°
Explanation:
The angle between force and displacement should be 0° in order to get the maximum work done.
Work done = Force x dcosФ°
Ф is the angle between force and displacement
When Ф is zero, the maximum work done is attained
When Ф is 90, the minimum work is done, in fact, work done is 0

The poles of the electromagnet reverse.
Turn off the battery supply.
Place a magnetic core inside the coll of wire.
Change the direction in which the current flows.
Answers
Answer:
1) The strength of the electromagnet increases → Place a magnetic core inside the coil of wire
2) The electromagnet turns off → Turn off the battery supply
3) The poles of the electromagnet reverse → Change the direction in which the current flows
Explanation:
when current passes through a coil it behaves a an electromagnet.
Magnetic field strength is given by
B = μ N I
N is no of turns and
I is the current through coil
μ is permeability of the medium or core in the coil.
1). Magnetic core increase permeability μ so it will strengthen magnetic field:
B = μ N I
2). When the battery turns off current becomes zeroi.e I=0
So B = μ N * 0
⇒ B = 0
so electromagnet turns off
3). Direction of magnetic field can be determine by right hand rule, i.e curl the fingers in the direction of current, thumb will point in the direction of north pole.
so changing current direction will change direction of magnetic field.
A potter's wheel moves from rest to an angu-
lar speed of 0.10 rev/s in 24.6 s.
Assuming constant angular acceleration.
what is its angular acceleration in rad/s?
Answer in units of rad/s
Answers
Answer:
angular acceleration =final angular speed + initial angular speed
time
=0.6283rad/s +0
24.6s
=0.6283/24.5
=0.025rad/s^2
Explanation:
first angular speed is equal to angular velocity and we will convert the unit to rad/s so 1rev/sec=6.283rad/s then angular acceleration is the rate at which the angular velocity changes with the time we have the final angular velocity,initial angular velocity and time now substitute the numbers in the formula and the value will be 0.025 rad per seconde square
