The time to complete a movement if angular velocity is increased is Angular speed
Angular speed is the price of speed at which an object or a particle is rotating round a middle or a specific factor in a given time period. it's also referred to as rotational pace. Angular pace is measured in attitude in keeping with unit time or radians per second (rad/s). The fee of alternate of angular speed is angular acceleration. let us analyze in extra element approximately the relation among angular speed and linear pace, angular displacement and angular acceleration.Angular pace plays an eminent position within the rotational movement of an item. We already understand that in an item showing rotational movement all the particles circulate in a circle. The linear pace of each collaborating particle is without delay associated with the angular velocity of the entire item.those become as vector products relative to each other. basically, the angular velocity is a vector amount and is the rotational speed of an object. The angular displacement of in a given period of time gives the angular velocity of that item.

B. moving slower in the positive direction
C. moving slower in the in the negative direction
D. moving faster in the negative direction
The pig is moving slower in the negative direction during the next 2 seconds.
What is acceleration?The term acceleration refers to the change in the velocity of the object with time. Now we know that velocity is a vector quantity. This implies that we have to take the magnitude and the direction into focus when we are discussing about the velocity.
Similarly, the acceleration is a vector quantity and the magnitude and the direction must also be taken into account when dealing with the acceleration.
In this case, it is clear that a pig on roller skates is moving with an initial velocity of -10 m/s and is accelerating at a rate of 2m/s/s.
Seeing that the velocity is negative, we can see that the pig roller coaster is moving the negative direction. Recall that the axes must be defined such that one is negative and one is positive.

which low-energy state of condensed matter is characterized by structural rigidity and resistance to changes of shape or volume? gas
Low-energy state of condensed matter is characterized by structural rigidity and resistance to changes of shape or volume is solid.
What is solid?When particles are arranged and packed closely -- compared to those in a gas or liquid -- and are relatively stable, they are considered to be in solid state. Solids tend to have a rigid shape, as the atoms or molecules of matter in the solid state are generally compressed and tightly connected through the chemical bonds. These bonds can produce an amorphous shape or regular lattice.
In electronics, the solid state refers to components and systems based entirely on semiconductor materials, such as silicon, germanium or gallium arsenide. Transistors and diodes -- the most common solid-state devices -- are often combined with resistors, capacitors and other components to create the integrated circuits (ICs). All the electronic systems incorporate ICs and, therefore, transistors.
The particles that make up solid have the lowest energy, and vibrate in place. This results in the characteristics of a solid, such as definite shape and volume. A solid is actually the frozen state of matter for substance. A substance does not have to freeze at cold temperature. For example, the faucet you have at your lab station in chemistry, and the faucets in your home are frozen the stainless steel; and so is your desk, pencils, pens, cell phones, and computers are all frozen. In fact anything solid is frozen.

A 1kg block sits 75m from the left. if the board is 4kg, where should the pivot point be placed to balance?
The pivot point should be placed 15m right from the 4kg board and 60m left from 1kg block to be balanced.
ExplanationLet d block be x and d board be y
so, x + y = 75 ...1
This problem needs to add torques about the pivot point. In order to be balanced, the torque must be equal on each side of the pivot point.
T block =T board
Use the equation for torque in this equation.
(F block)(d block )=(F board )(d board )
The force of each object will be equal to the force of gravity.
(m block )g(d block )=(m board )g(d board )
Gravity is cancelled from each side of the equation. for simplicity.
(m block )(d block )=(m board )(d board )
⇒ 1 kg × x = 4kg × y
⇒ 1/4 = x/y
⇒ x = 4y ...2
Now applying eq 2 in eq 1 we get
⇒ 4y + y = 75
⇒ 5y = 75
⇒ y = 75/5
= 15
Thus, the pivot point should be placed 15 m right from the 4kg board and 60 m left from 1kg block to be balanced.

An analytical chemist is titrating of a solution of propylamine with a solution of . the of propylamine is . calculate the ph of the base solution after the chemist has added of the solution to it.
After the equivalence point, pH of the base solution is 1.52.
What is equivalence point?
The number of moles of base = 88.4 x 0.2700 = 23.868
The number of moles of acid = 0.4300 x 66.3 = 28.509
After the equivalence point,
Net moles of acid = 28.509 - 23.868
= 4.641mol
Total vol. of solution = 88.4 + 66.3 = 154.7mL
Conc. of Acid = moles/volume = 4.641/154.7 = 0.03M
pH = [tex]-log[H^{+} ][/tex] = -Log[0.03]
pH = 1.52
Hence, the pH of the base solution is 1.52.
The titration's equivalence point occurs when the amount of titrant applied is just sufficient to totally neutralize the analyte solution. In an acid-base titration, the solution only comprises salt and water at the equivalence point, where moles of base equal moles of acid.
The equivalency point for acid-base titrations is extremely simple to identify. To create a titration curve, different quantities of titrant are added, and then the pH of the solution is measured using a pH meter. Then, the curve's equivalence point can be determined.

Answer:
Average speed: approximately [tex]76.9\; {\rm m\cdot s^{-1}}[/tex].
Average velocity: approximately [tex]38.5\; {\rm m \cdot s^{-1}}[/tex] (to the north.)
Explanation:
Consider an object that travelled along a certain path. Distance travelled would be equal to the length of the entire path.
In contrast, the magnitude of displacement is equal to distance between where the object started and where it stopped.
In this question, the path George took required him to travel [tex]750\; {\rm m} + 250\; {\rm m} = 1000\; {\rm m}[/tex] in total. Hence, the distance George travelled would be [tex]1000\; {\rm m}[/tex]. However, since George stopped at a point [tex](750\; {\rm m} - 250\; {\rm m}) = 500\; {\rm m}[/tex] to the north of where he started, his displacement would be only [tex]500\; {\rm m}[/tex] to the north.
Divide total distance by total time to find the average speed.
Divide total displacement by total time to find average velocity.
The total time of travel in this question is [tex]13\; {\rm s}[/tex].. Therefore:
[tex]\begin{aligned}\text{average speed} &= \frac{\text{total distance}}{\text{total time}} \\ &= \frac{1000\; {\rm m}}{13\; {\rm s}} \\ &\approx 76.9\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].
[tex]\begin{aligned}\text{average velocity} &= \frac{\text{total displacement}}{\text{total time}} \\ &= \frac{500\; {\rm m}}{13\; {\rm s}} && \genfrac{}{}{0px}{}{(\text{to the north})}{}\\ &\approx 38.5\; {\rm m\cdot s^{-1}} && (\text{to the north})\end{aligned}[/tex].

The speed of a moving rod that has a length 55 % that of an identical rod in terms of c will be v/c= 0.824
or v = 0.824c.
The formula for length contraction rod is,
L = L1{√(1-v^2/c^2)}
Here L is the length of the moving rod
L1 is the length of the stationary rod
v is the velocity with which the rod is moving
c is the speed of light
We are given that
L = 55% of L1 = 0.55L1
Putting the values in the above equation,
0.55L1 = L1{√(1-v^2/c^2)}
0.55 = {√(1-v^2/c^2)}
Squaring both sides
(0.55)^2 = 1- v^2/c^2
V^2/c^2 = 1 - 0.3025
V^2/c^2 = 0.6975
v/c = 0.824
Thus, the speed of a moving rod that has a length 55 % that of an identical rod in terms of c will be v/c= 0.824 or v = 0.824c.

Consider the electronic transition from n = 7 to n = 4 in the hydrogen atom. is light absorbed or emitted? calculate the energy, the frequency and wavelength (nm) of the photon involved.
Light is emitted, energy is 9.16 × [tex]10^{-20}[/tex] J , frequency is 1.38 × [tex]10^{-14}[/tex] [tex]s^-[/tex]
and wavelength is 2.17 × [tex]10^{-6}[/tex] m
Explanation
n = 7 → n = 4
higher → lower
Light is emitted
[tex]\Delta[/tex]E = [tex]\frac{-13.6}{7^2} - (\frac{-13.6}{4^2})[/tex]
[tex]\Delta[/tex]E = 0.85 - 0.277
= 0.572 eV
[tex]\Delta[/tex]E = 9.16 × [tex]10^{-20}[/tex] J -> [energy calculated]
[tex]\Delta[/tex]E = hv (h is Planck's constant and v is frequency)
v = [tex]\frac{\Delta E}{h}[/tex] = [tex]\frac{9.16 * 10^{-20}}{6.626 * 10^{-39}}[/tex]
v = 1.38 × [tex]10^{-14}[/tex] [tex]s^-[/tex] ->[frequency calculated]
[tex]\Delta[/tex]E = [tex]\frac{hc}{\Lambda}[/tex] (c is speed of light)
[tex]\Lambda[/tex] = [tex]\frac{hc}{\Delta E}[/tex]
[tex]\Lambda[/tex] = [tex]\frac{6.626 * 10^{-34} . 3*10^8 m/s}{9.16 *10^{-20 J} }[/tex]
[tex]\Lambda[/tex] = 2.17 × [tex]10^{-6}[/tex] m ->[wavelength calculated]

the planet earth orbits the sun within a period of one year. in this problem, you may assume the radius
The correct answer is 29883.3m/s
The pace at w.hich an object's position changes in relation to a frame of reference is known as its velocity, which is a time-dependent quantity. The speed and direction of an object's motion are its velocity. The rate at which an object's velocity changes in relation to time is defined as its acceleration.
The following kinematic equation can be used to connect velocity and acceleration:
v_1=v_0+at
Where v_1 denotes the ultimate velocity, v_0 denotes the starting velocity, a denotes the acceleration, and t is the passing of time.
Calculate the length of the Earth's orbit around the Sun to get started. For this issue, a circle rather than an ellipse can be used to represent the Earth's orbit.
Circumference = C=πD=2πR
=2π(1.5×10km)
=9.424π×10^8
Do a dimensional analysis to convert the speed of the Earth around the Sun from miles per hour to metres per second:
s_earth= 9.424π×10^8/1year × (1year×100m×1day×1hour×1min)/(1km×365days×24hours×3600seconds)
=29883.3m/s
