How do I convert 90 mmHg to SI unit of pressure?To convert 90 mmHg to SI unit of pressure, must bear in the mind the SI unit of pressure.
From the system of international (SI) unit, we understood that the SI unit of pressure is Pascal (Pa)
Now, we shall convert 90 mmHg to SI unit of pressure (i.e Pascal) as illustrated below:
Pressure (in mmHg) = 90 mmHgPressure (in Pascal) = ?From conversion identities,
760 mmHg = 101325 Pa
Therefore,
90 mmHg = (90 mmHg × 101325 Pa) / 760 mmHg

in a single-slit experiment, the slit width is 190 times the wavelength of the light. part a what is the width (in mm) of the central maximum on a screen 1.4 m behind the slit?
The width (in mm) of the central maximum on a screen 1.4 m behind the slit = 0.014 mm.
Diffraction of lightDiffraction of light on a single slit will produce maximum interference from the slit if the path difference between the light coming is:
(2n+1) ½ λ
Maximum interference if the difference in the paths taken by light from adjacent slits is equal to an integer multiple times the wavelength or also an even number times the half wave.
To determine the width from the maximum center on the screen behind the slit. use the equation:
Ym = mλD/a
We have,
a = 190 λ
So,
Y₁ = (1)λ (1.4) / 190 λ

A typical flashlight battery will produce a 0.50-A current for about 3 h before losing its charge.
Determine the total number of electrons that have moved past a cross section of wire connecting the battery and lightbulb.
Express your answer using two significant figures.
A typical flashlight battery will produce a 0.50-A current for about 3 h before losing its charge.The number of electron is: 3.4 × 1O²²
What is flashlight battery?Traditional flashlights emit light from an incandescent bulb that is powered by a battery. Battery current warms the filament wire within the light bulb, causing it to glow and emit light.
When a flashlight's circuit, which consists of the batteries, switch, and light bulb, is complete, the chemical energy in the batteries is transformed into electrical energy. The light bulb converts electrical energy into light (electromagnetic / radiant energy) and some heat (thermal energy).
Given that,
current = 0.50 A
time = 3 h
The expression for current, I = Q/t
where Q = charge and t = time taken
The mathematical expression for quantization of the charge,
Q = N × e
Where, N = is the number of the charged particle and e = is the charge on an electron.
Now, calculate the amount of charge,
I = Q/t
or, 0.50 A = Q / [(3h ×3600 sec)/1 h]
or, Q = 5400 C
Next, calculate the number of electrons:
Q = N × e
or, 5400 C = N × ( 1.6 × 10⁻¹⁹ C)
or, N = 3375 × 1O¹⁹
Thus, the number of electron is: 3.4 × 1O²²

Speed the block has as it passes through equilibrium if the horizontal surface is frictionless is 0.79 m/s and if the surface is with friction then the speed is 0.53 m/s.
Friction is the resistance to motion of one object moving relative to another. There are two main types of friction, static and kinetic friction.
Given mass of the block m = 2.00 kg and
The force constant k = 500 N/m
The block is pulled to a position of x, = 5.00 cm = 0.05 m
a) Hence the potential energy stored in the block is
U = 1/2Kx^2 =. = 0.625 J
as the surface is frictionless, hence the potential energy changes into kinetic energy
And is given by
1/2mv² = 0.625 J
Given mass of the block is m = 2.00 kg
Hence, 1/2(2.00)v² = 0.625
v=0.79 m/s
b) Now when the surface is with friction,
Then the amount of work done in over coming the friction is
W=umgx=(0.35) (2.00)(9.8) (0.05) = 0.343 J
Hence the loss in energy from the potential energy is
ΔU = U-W= 0.625 J - 0.343 J = 0.282 J
Hence this energy is converted into the kinetic energy of the block
Hence 1/2 mv^2 = 0.282 J

Why is it called gravitational force?Because it consistently attempts to pull objects together rather than pushing them apart, the gravitation force is known as attractive. It is obvious that the gravitational force directly relates to the masses of the two interacting objects; larger, more massive stars will pull apart with a stronger gravitational force. Because of size of the Earth and how far out from its core humans are on its surface, attraction (or the acceleration caused by gravity) equals 9.81 m / sec squared on Earth's surface.

You move a little one way or the other, but mostly you are just at rest (although sweating some). The magnitude of the force exerted by you on your friend is equal to the magnitude of the force exerted by your friend on you. This is because of newton's third law of motion that, forces are always equal and opposite, so when you pull on your friend, they pull back on you with an equal and opposite force. Therefore, both forces are the same.

Match the examples of types of learning to the term for that type of learning Habituation A. The first time you went to a party at your friends' house you weren't sure if you had to take your shoes off when you entered or not so you looked at what other people were doing and imitated them. Sensitization Phase-specific learning B. Your friend is driving and did not put their seatbelt on so the car is beeping at them. You are becoming increasingly annoyed by the beeping sound. Classical conditioning C. You typically eat popcorn while watching Netflix. You ran out of popcorn and noticed that when you started watching Netflix, you were hungry and craving popcorn Operant conditioning Observational learning D. You enjoy spending time on social media but need to study more, so you made a plan to allow yourself to spend 15 minutes on social media for every hour you study. Your studying increased as a result of this plan E. When geese are born they learn to follow the first large moving object they see F. Your smoke detector battery died 20 minutes ago so the smoke detector has been beeping. You no longer notice it though.

Habituation is a sort of learning, right?A non-associative learning process known as habituation occurs when a stimulus is presented repeatedly or for an extended period of time and results in a decrease in the innate (quasi) response to that stimulus.
What are the three different types of psychological learning?Classical and operant conditioning, operant, and learning theory are the three main categories of learning.Associative learning refers to the process of creating associations between related events, and both classical & operant conditioning fall under this category.

a water pipe having a 2.5 cm inside diameter carries water into the basement of a house at a speed of 0.90 m/s and a pressure of 170 kpa. if the pipe tapers to 1.2 cm and rises to the second floor 7.6 m above the input point, what are the (a) speed and (b) water pressure at the second floor?
A water pipe having a 2.5 cm inside diameter carries water into the basement of a house at a speed of 0.90 m/s and a pressure of 170 kpa.
Given that the radius of the first end is r _1 = 2.5cm /2
= 1.25 cm
speed at the first end is v_1 = 0.90m/s
radius at the other end is r_2 = 1.2cm /2
= 0.6cm
Pressure is P = 170*10^3 Pa
a ) From the equation of continuity v_1A_1 = v_2 A_2
m)^20.90m/s*π(1.25*10^-2 = v_2π(0.6*10^-2m)^2
v_2 = 3.90m/s
b) Pressure at the second floor is P_2 = P_1 - ρgh + 1/2 ρ (v_1^2 - v_2^2 )
= 170*10^3 Pa - 1000 *9.8 * 7.6m + 1/2 *1000 ( (0.90m/s)^2 - ( 3.90m/s)^2 )
= 102.7 kPa
The rate of change in position of an object in any course. Speed is measured because the ratio of distance to the time wherein the distance became included.
