A flea jumps straight up to a maximum height of 0.410 mm . what is its initial velocity v0v0v_0 as it leaves the ground

The space between the screen fringes will be closed if the complete apparatus is submerged in water.

The space between two consecutive bright spots (maximas, when constructive interference occurs), or two consecutive dark patches, is known as the fringe width (minimas, where destructive interference occurs). All of the fringes in Young's double-slit experiment are the same length. The formula yields the fringe width. β = λD/d. Because it depends on L, the spacings between various fringes get smaller as the slit distance gets bigger. Since the space between various fringes is wavelength dependent, increasing the light's wavelength also increases that separation.

In comparison to air, water has a shorter wavelength of light. Therefore, when the device is submerged in water, the fringe width will diminish.

An inert atmosphere was obtained by adding nitrogen in a room that measures 11.0 ft x 11.0 ft and has a 8.00 ft ceiling. The number of liters of nitrogen that were used to fill the room is : (D) 2.74 x 104  Liters.

The number of liters of nitrogen that were used to fill the room

= Volume of room in cm3 x 1 Liters / 103 cm3

Volume of room in cm3 = 11.0 ft x  (30.48 cm / 1 ft) x  11.0 ft x  (30.48 cm / 1 ft) x 8.00 ft x (30.48 cm / 1 ft)

= 27410707.501 cm3  or 2.741 x 107 cm3

And since  1 Litres = 103 cm3

Volume of room in cm3  = 2.74 x 107 cm3

Now putting these values in the above equation we get

So, the number of liters of nitrogen that were used to fill the room

= Volume of room in cm3 x 1 Liters / 103 cm3

= 2.74 x 107 cm3  x 1 Liters / 103 cm3

= 2.741 x 104  Liters

Thus, an inert atmosphere was obtained by adding nitrogen in a room that measures 11.0 ft x 11.0 ft and has a 8.00 ft ceiling. The number of liters of nitrogen that were used to fill the room is 2.74 x 104  Liters.

where,

[ [tex]A^{-1}[/tex] ] represents deprotonated form

[ HA ] represents protonated form

Consider pH = p[tex]K_{a}[/tex]

In this case,

A father and his young daughter are ice skating. According to it, the daughter has greater speed.

According to Newton’s third law, when two bodies come into contact, they exert forces on one another that are equal in size and directed in the opposite direction. The law of action and reaction is another name for the third law.

This law applies to bodies in uniform or rapid motion and is crucial for addressing problems of static equilibrium, where all forces are in balance. The forces it discusses are actual phenomena, not just accounting tricks.

If there is a net force operating on a body, it moves faster in line with the second rule.

If there is no net force acting on the body, either because there are no forces at all or because all forces are precisely balanced by opposing forces, the body does not accelerate and is said to be in equilibrium.

On the other hand, it can be assumed that a body that appears to be moving slowly has no net force acting on it.

The correct answer for percentage of the compound is left after 3.32 minutes is 55 % .

We use the formula A(t) = A0e-kt for decomposition, where A0 is the initial amount of decomposed substance at t = 0, k is the decay constant, t is the time elapsed, and A(t) is the amount after time t.

The percentage of decomposed compound left after a time t is, [A(t)], divided the the initial amount, [A0], time 100, or A/A0*100:

A = A0e-kt

A/A0 = e^- 0.00586t, [k = 0.00299, divide both sides by A0]

A/Ao = e^(-0.00299*199), [t = 3.32 min*(60 sec/ 1 min) =199 sec]

A/A0 = . 0.551= 55%, (* 100, rounded)

The Arrhenius equation is k = Ae(-Ea/kT), where A is the frequency or pre-exponential factor and e(-Ea/RT) is the fraction of collisions at temperature T that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea).

The enterprise must slow down to [tex]-2.5 km/s^{2}[/tex] to avoid a collision.

Average velocity is defined as the difference between the change in position or displacement (x) and the time intervals (t) during which the displacement occurs. The average velocity may be positive or negative depending on the displacement's direction. The unit of measure for average velocity in the SI is meters per second (m/s or m[tex]s^{-1}[/tex]).

Only when acceleration is constant and motion is on a straight line can the equations of kinematics be used.

Let us assume that,

A = Starship enterprise

B = Klingon ship

Considering that the starship enterprise slows down steadily, the following would be the average velocity:

[tex]v_{a}__{i}[/tex] =( [tex]v_{a}__{i}[/tex] + [tex]v_{a}__{f}[/tex] )/2

where [tex]v_{a}__{f}[/tex] = 0 since it must come to a stop

[tex]v_{a}[/tex] = (50 + 0)/2

[tex]v_{a}[/tex] = 25 km/s

As a result, A must travel 100 km in addition to the distance B travels during that period before coming to a stop:

[tex]d_{A}[/tex] = [tex]d_{B}[/tex] + 100

25t = 20t + 100

5t = 100

So,

[tex]d_{A}[/tex] = 25t

[tex]d_{A}[/tex] = 25(20)

[tex]d_{A}[/tex] = 500 km

and

[tex]d_{A}[/tex] = [tex]v_{a}__{i}[/tex] × t + [tex]\frac{1}{2} a t^2[/tex]

500 = 50(20) + [tex]\frac{1}{2} a(20)^2[/tex]

We need to know about the uniform motion to solve this problem. The uniform motion is the motion of an object which has acceleration applied. It can be determined as

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time interval and s is displacement.

From the question above, we know that:

a = 1.25 m/s²

vo = 0 m/s

vt = 5.3 m/s

By using the second equation, we can calculate the distance

vt² = vo² + 2a . s
