hello I wanna know what is the Newton first is also called the law ​

The speed of the larger piece is approximately 12 m/s.

We can use conservation of momentum and conservation of energy to solve the problem. Since the rock is initially at rest, the total momentum of the system is zero.

After the explosion, the momentum of one piece is equal in magnitude but opposite in direction to the momentum of the other piece, so the total momentum of the system is still zero.

Therefore, the two pieces must have equal and opposite momenta. Let the momentum of each piece be p.

By conservation of energy, the total kinetic energy of the two pieces is equal to the initial potential energy stored in the dynamite. Let this be E.

So, we have:

p = -p (since the momenta are equal and opposite)

2p = 2m1v1 = 2m2v2

v1 = (m2/m1) v2

E = 1/2 m1  + 1/2 m2 \(v2^2\)

Substituting v1 in terms of v2, we get:

E = 1/2 \((m2/m1)^2\) m1 \(v2^2\) + 1/2 m2 \(v2^2\)

324 = 1/2 \((m2/m1)^2\) m1\(v2^2\) + 1/2 m2 \(v2^2\)

Solving for v2, we get:

v2 = \(\sqrt{2E/(m1 + m2)}\) = \(\sqrt{2(324)/(0.8 + 1.2)}\) = 12 m/s

Therefore, the speed of each piece is 12 m/s.

The distance horizontally, from the initial dropping point that the pit hit the ground is 11.2 meters.

The formula of distance is Distance = Speed x Time which is measured in meters.

7. The height of the car window h = 5.0 metres

The velocity of the car is 35 m/s.

The horizontal velocity of the cherry pit when it is released is then the same as that of the car Vx = 35m/s

The dropped cherry pit falls freely under gravity with a vertical downward acceleration equal to the acceleration due to gravity, g

Initially, the pit has no vertical component of velocity.

Therefore the time it takes to reach the ground t = \(\sqrt{} \frac{2h}{g}\)

t = √10/9.8

t= 0.32 seconds

The horizontal component of velocity is a constant, since there are no forces acting in the horizontal direction.

Therefore the horizontal distance travelled by the pit by the time it hits the ground is Vx * time

= 35 x 0.32

= 11.2 meters

The velocity of Sam just before hitting the ground is 294 m/s.

The above situation represents a case of motion in one dimension.

This type of motion is governed by the following three equations of motion,

v = u + at

v² - u² = 2as

S = ut + 1/2 at²

As in the given case, the acceleration and time have been given and the final velocity is to be calculated, therefore the 1st equation can be used,

v = u+ at

As Sam jumped from the plane, his initial velocity is zero.

So,

v = 0 + 9.8(30)

v = 294 m/s.

Thus, Sam's velocity just before hitting the ground is 294 m/s.

Windchill represents the combined effect of ambient temperature and wind speed.

Windchill is a measure of how cold it feels outside due to the combined effect of ambient temperature and wind speed. It takes into account the fact that wind increases the rate of heat loss from exposed skin, making the air temperature feel colder than it actually is.

When wind blows over our skin, it carries away the heat that our bodies produce, leading to a more rapid cooling effect. As a result, even if the actual air temperature is above freezing, the wind can make it feel much colder.

Meteorologists use a wind chill index or formula to calculate the perceived temperature based on the actual air temperature and wind speed. The wind chill index provides an estimation of how cold it feels to the human body and helps people understand the potential impact on their comfort and safety when exposed to cold and windy conditions.

It's worth noting that different regions and countries may use different formulas or indices to calculate wind chill, but the underlying concept remains the same: windchill combines the effects of temperature and wind speed to assess the perceived coldness.

solid iron can be made by the electrolysis of iron (ii) bromide aqueous solution, febr 2 (aq) 13.4 amperage is required to plate out 111.7 grams of fe(s) from a febr 2 (aq) solution in a period of 8.00 hours.So,option  e is correct.

To determine the amperage required for the electrolysis of iron (II) bromide (FeBr2) to plate out a certain amount of iron (Fe), we can use Faraday's laws of electrolysis. Faraday's laws state that the amount of substance produced or consumed during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.

The equation relating the amount of substance (in moles) produced or consumed during electrolysis is:

moles = (current × time) / (n × F)

where:

current = amperage (in amperes)

time = duration of electrolysis (in seconds)

n = number of electrons involved in the reaction

F = Faraday's constant (approximately 96,485 coulombs per mole of electrons)

First, we need to convert the given mass of iron (111.7 grams) to moles using its molar mass:

moles of Fe = mass / molar mass

moles of Fe = 111.7 g / (55.845 g/mol) (molar mass of iron)

Next, we need to determine the number of electrons involved in the reduction of iron (II) bromide. In this case, Fe2+ ions are reduced to solid iron (Fe), and each Fe2+ ion gains two electrons.

n = 2 (number of electrons transferred per mole of Fe)

Now we can calculate the total charge (in coulombs) required for the electrolysis:

charge = (moles of Fe) × (n × F)

To convert the given duration of electrolysis from hours to seconds:

time = 8.00 hours × 60 minutes/hour × 60 seconds/minute

Finally, we can calculate the required amperage:

amperage = charge / time

Let's perform the calculations:

moles of Fe = 111.7 g / 55.845 g/mol ≈ 1.999 mol

charge = (1.999 mol) × (2 × 96,485 C/mol) ≈ 387,694 C

time = 8.00 hours × 60 minutes/hour × 60 seconds/minute ≈ 28,800 s

amperage = 387,694 C / 28,800 s ≈ 13.47 A

The amperage required to plate out 111.7 grams of Fe from a FeBr2 solution in a period of 8.00 hours is approximately 13.4 amperes.

Explanation:

To solve this circuit we must remember that there are two fundamental types of construction in series and parallel.

* a serial circuit there is only one path for current

in this circuit the constant current in the entire circuit and the voltage is the sum of the voltage of each term

* Parallel circuit in this there are two or more paths for the current

in this circuit the voltage is constant and the east is divided between each branch

with these principles let's analyze the proposed circuit

The DC battery is in parallel with resistor R1 and the equivalent of the other branch,

as in a parallel circuit the voltage is constant

               V₁ = 6 V

in the other branch (23) it forms a series construction, where the current is constant

               6 = iR₂ + iR₃

as they indicate that each resistance has the same value

              6 = 2 iR

In those two cities depicted in the picture, one city being further west or east does not cause significant temperature change. (Too north or too south can change this but this is not what we are supposed to find.) Rules out A.

Latitude is basically where a city is on the map, either north or south, and they have the same latitude, so B doesn't make sense.

A difference between an average high and low does nothing to why it would be colder in one place over another.

C is the logical answer for this question. The elevation, or how high you're elevated, changes the temperature. The higher the elevation, the colder it becomes since you're more closer to the clouds, and the clouds are actually really cold.

The electric field of a plane wave propagating in a nonmagnetic material is given by:

\(E = [y 6 sin(π × 107λ) + 24 cos(π × 107λ)] V/m\)

where λ is the wavelength in meters and T is the time in seconds.

(a) The wavelength of the wave can be determined from the equation:

λ = v/f

where v is the velocity of light in the material and f is the frequency of the wave.

Since the wave is propagating in a nonmagnetic material, we can assume that the velocity of light is equal to c, the speed of light in vacuum.

The frequency of the wave can be determined from the argument of the sine and cosine functions as:

f = 0.2/T

Substituting the values given in the equation, we get:

\(λ = c/f = c × T/0.2 = (3 × 108 m/s) × (5 × 10-9 s)/0.2 = 7.5 × 10-3 m\)

Therefore, the wavelength of the wave is 7.5 × 10-3 m.

(b) The magnitude of the electric field can be written as:

\(Er = |E| = √[(y 6 sin(π × 107λ))2 + (24 cos(π × 107λ))2] V/m\)

Substituting the values given in the equation, we get:

Er = √[(6 sin(π × 107 × 7.5 × 10-3))2 + (24 cos(π × 107 × 7.5 × 10-3))2] V/m

Er = √[(6 × 0.707)2 + (24 × 0.707)2] V/m = 24.5 V/m

Therefore, the magnitude of the electric field is 24.5 V/m.

(c) The magnetic field can be determined from the equation:

H = E/Z

where Z is the impedance of the material, which is given by:

Z = sqrt(mu/epsilon)

where mu is the permeability of the material and epsilon is the permittivity of the material.

Since the material is nonmagnetic, we can assume that mu is equal to mu0, the permeability of vacuum.

The permittivity of the material can be determined from the wave velocity as:

v = 1/sqrt(mu epsilon)

Substituting the values given in the equation, we get:

\(epsilon = 1/(v2 mu0) = (3 × 108 m/s)2/(4π × 10-7 H/m) = 8.85 × 10-12 F/m\)

Therefore, the permittivity of the material is 8.85 × 10-12 F/m.

The impedance of the material can be determined as:

\(Z = sqrt(mu0/epsilon) = sqrt(4π × 10-7/8.85 × 10-12) = 377 ohms\)

Substituting the values of Er and Z in the equation for H, we get:

H = Er/Z = 24.5/377 = 0.065 A/m

Therefore, the magnitude of the magnetic field is 0.065 A/m.
