the residual magnetism is coercive force or coercivity.

What is H in hysteresis?

Hysteresis is characterized as a lag of magnetic flux density (B) behind the magnetic field strength (H). All ferromagnetic materials exhibit the phenomena of hysteresis.

What is hysteresis value?

Hysteresis is defined as the deviation of the contact angle from its theoretical (and mean) value due to physical phenomena like microscopic surface defects and roughness.

What is the use of hysteresis?

In control systems, hysteresis can be used to filter signals so that the output reacts less rapidly than it otherwise would by taking recent system history into account

What is cohesive force ?

Cohesive force is the attractive force between the same type of molecules. It can also be called a collective intramolecular force. : In water, hydrogen bonds are held together by the cohesive force that creates a surface tension

A ball is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the wa

vovangra [49]

Answer:

a) 48.5 ft/s

b) 36.5 ft

c) -80.3 ft/s

Explanation:

The equation of motion of the ball is :

y(t) = -16.1 ft/s^2 * t^2 + Vo*t

Where Vo is the initial velocity

If y(5s) = - 160 ft:

-160 ft = -16.1 ft/s^2 * (5 s)^2 + Vo*(5s)

Solving for Vo

Vo = (16.1*25- 160) ft / 5s = 48.5 ft/s

To answer this question we must first know when the velocity became zero, at this time is when the ball was at its highest point.

v(t) = -32.2 ft/s^2 * t + Vo

t = Vo/32.2ft/s^2 = 1.5 s

And now, the highest point which the ball reached is given by:

y(1.5s) = -16.1 ft/s^2 * (1.5)^2 + Vo*(1.5s)

y(1.5s) = 36.52 ft

We now need the time at which y(t') = -64 ft

-64 = -16.1*t'^2 + 48.5*t'

By means of the quadratic formula, we find that

t' = 4.00498 s ≈ 4 s

And the velocity at t = 4s is:

v(4s) = -32.2 ft/s^2 * 4s +48.5 ft/s = -80.3 ft/s

What is storage of energy

Talja [164]

Hey,

Storage of energy is known as potential energy. If you take a spring for example, and you stretch it then you hold it, it has the energy you put into it but it is potential since it's not moving. Of course once you let go of it its potential energy turns into kinetic energy.

There are other examples as well, such as a battery. I decided to use the spring example because it is simpler.

I hope it helped.

I wrote all that^.

PLEASE HELP ME WITH THIS ONE QUESTION

shtirl [24]

Answer:

$\lambda=1.39\times 10^{-4}\ s^{-1}$

Explanation:

Given that,

The half-life of Barium-139 is $4.96\times 10^3$

A sample contains $3.21\times 10^{17}$ nuclei.

We need to find the decay constant for this decay. The formula for half life is given by :

$T_{1/2}=\dfrac{0.693}{\lambda}\\\\\lambda=\dfrac{0.693}{T_{1/2}}$

Put all the values,

$\lambda=\dfrac{0.693}{4.96\times 10^3}\\\\=1.39\times 10^{-4}\ s^{-1}$

So, the decay constant is $1.39\times 10^{-4}\ s^{-1}$ .

How far will you travel if you fly at 100 miles per hour for 2 hours and 30 minutes?

enyata [817]

If you fly at 100 miles per hour for a time of 2 hours and 30 minutes you will be a: 250 miles far

The formula and procedure we will use to solve this exercise is:

x = v * t

Where:

x = distance
t = time
v = velocity

Information about the problem:

v = 100 miles/h
t = 2,5 h
x=?

Applying the distance formula we have that:

x = v * t

x= 100 miles/h * 2,5 h

x = 250 miles

<h3>What is velocity?</h3>

It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).
