which type of object would likely cause more damage if it struck near an urban area: a small metallic one, or a large stony/icy one?

Therefore, the speed of the two skaters after the collision is 3.37 m/s. The total momentum of the system before the collision is equal to the total momentum of the system after the collision.

We can set up an equation to solve for the final velocity of the two skaters:

(mass of skater 1 x velocity of skater 1) + (mass of skater 2 x velocity of skater 2) = (total mass of skaters x final velocity of skaters)

(71.2 kg x 6.01 m/s) + (55.9 kg x 0 m/s) = (71.2 kg + 55.9 kg) x final velocity

428.672 + 0 = 127.1 x final velocity

final velocity = 3.37 m/s

Therefore, the speed of the two skaters after the collision is 3.37 m/s.

Answer:the answer is friction and mass.

Explanation:The reason that Vehicle 2 fell off the cliff in Claire's test of the collision scene, but Vehicle 2 did not fall off the cliff in the film Iceworld Revenge is because of the friction and mass. A different friction, called foam, is used in Claire's test. The foam has a really low friction that caused vehicle 2 to fall from the cliff. According to evidence card B which states that, “In Iceworld Revenge, Vehicle 2 moves slowly toward the cliff after the collision, halting only before it goes over the side. In Clasir's test, Vehicle 2 went over the cliff at full speed”.This evidence confirms my arguments that in the film, vehicle 2 did not drive as quickly as in the film scene of Claire . __ ______________________________________________________________________________

Distance of train after 1.8 h is 485.099 m

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

Distance of the first plane = 650 x 1.8 = 1170 m

Distance of the second plane = 590 x 1.8 = 1062m

The angle between 2 planes

161◦ - 16.9◦ = 144.1°

Using the law of cosine

d^2 = (1170)^2 + (1062)^2 - 2*1170*1062*cos 144.1°

d = 485.099 m

Hence, distance of train after 1.8 h is 485.099 m

The momentum, p, of any object having mass m and the velocity v is

\(p=mv\cdots(i)\)

Let \(M_L\) and \(M_S\) be the masses of the large truck and the car respectively, and \(V_L\) and V_S be the velocities of the large truck and the car respectively.

So, by using equation (i),

the momentum of the large truck \(= M_LV_L\)

and the momentum of the small car \(= M_SV_S\).

If the large truck has the same momentum as a small car, then the condition is

\(M_LV_L=M_SV_S\cdots(ii)\)

The equation (ii) can be rearranged as

\(\frac {M_L}{M_S}=\frac {V_S}{V_L} \; or \; \frac{M_L}{V_S}=\frac{M_S}{V_L}\)

So, the first scenario:

\(\frac {M_L}{M_S}=\frac {V_S}{V_L}\)

\(\Rhghtarrow M_L:M_S=V_S:V_L\)

So, to have the same momentum, the ratio of mass of truck to the mass of the car must be equal to the ratio of velocity of the car to the velocity of the truck.

The other scenario:

\(\frac{M_L}{V_S}=\frac{M_S}{V_L}\)

\(\Rhghtarrow M_L:V_S= M_S:V_L\)

So, to have the same momentum, the ratio of mass of truck to the velocity of the car must be equal to the ratio of mass of the car to the velocity of the truck.

A total differential is an equation in which all the differentials can be integrated independently of each other. To verify that the given expressions are total differentials, we must check if they meet the conditions of being an exact differential function.The given expression is not an exact differential function.

According to the exact differential function, an expression dQ should be equal to the sum of two partial derivatives of the same function. i.e, dQ= dP+ dRA primitive function of an expression is obtained by integrating the given expression partially. Let's solve the given expressions, one by one:

1. Expression : (x² + 2xy-y²)dx + (x²-2xy - y²)dy. Now, we need to find the partial derivatives of the above function with respect to x and y.∂P/∂x = x² + 2xy - y²  ∂Q/∂y = x² - 2xy - y².

On verifying, we get:∂P/∂x = ∂Q/∂y.

Hence, the given expression is an exact differential function.

To find the primitive function, we need to integrate any one of the partial derivatives with respect to x and other with respect to y.

∴ P(x,y) = ∫(x² + 2xy - y²)dx = x³/3 + x²y - xy² + C1 and ∴ Q(x,y) = ∫(x² - 2xy - y²)dy = x²y - y³/3 + C2.

Therefore, the primitive function of the expression is: P(x,y) = Q(x,y) = x³/3 + x²y - xy² - y³/3 + C2.

Expression : (2xcosy - y² sinx) dx + (2ycosx - x² siny) dy. Now, we need to find the partial derivatives of the above function with respect to x and y.∂P/∂x = 2cosy  ∂Q/∂y = 2ycosx.

On verifying, we get:∂P/∂x ≠ ∂Q/∂y .

When an object is placed on the surface of two planets that have the same mass but are very different in size, then the the object would experience a greater gravitational pull on the smaller planet.

What is the weight of an object and what is acceleration due to gravity?

Weight of an object:

        W = mg

Where;

The object's mass is m.

Gravitational acceleration, or g, is measured.

Acceleration due to gravity, g:

The square of the distance from the planet's core and the acceleration caused by gravity, or g, are inversely proportional. Likewise, if there were two planets with the same mass but different sizes. Take into account the fact that planet A's radius is smaller than planet B's radius. This implies that the planet A's g will be higher than the planet B's g. Since the object's mass is constant, the weight of the object on planet A will be higher than the weight of the object on planet B.

Hence, The object would experience a greater gravitational pull on the smaller planet.

The spectrum observed from the Sun (or any star) would exhibit an absorption spectrum. This is because the outer gaseous atmosphere of the star absorbs specific wavelengths of light, resulting in dark absorption lines in the spectrum.

In the cooler, lower-density outer atmosphere, where white light from the star travels, some atoms or molecules in the atmosphere absorb photons with particular energy. In the spectrum, these absorptions show up as black lines at specific wavelengths. The specific set of absorption lines that each element or molecule generates results in a distinctive pattern that can be used to identify the elements that are present in the star's atmosphere.

The absorption spectrum offers insightful data on the chemical make-up and physical characteristics of the star.

Estimating the number of apples that is the energy equivalent of 1 gallon of gasoline is difficult, as the energy content of both substances is different. However, we can calculate the energy content of one gallon of gasoline and compare it to the energy content of one apple. So, approximately 1,045,454 medium-sized apples will be the energy equivalent of one gallon of gasoline.

Explanation:

What is the energy content of 1 gallon of gasoline?

The energy content of gasoline is measured in British Thermal Units (BTUs). According to the US Energy Information Administration, one gallon of gasoline contains approximately 115,000 BTUs.Therefore, to calculate the number of apples that are the energy equivalent of one gallon of gasoline, we need to determine the energy content of one apple.

The rotation of the angle of reflection from its original position is 20°.When a mirror is rotated at an angle.

Since the angle of incidence is equal to the angle of reflection, the angle of reflection also changes by 20° (twice the angle of rotation) from its original position. Therefore, the rotation of the angle of reflection from its original position is 20°. The rotation of the angle of reflection from its original position when a mirror is rotated at an angle of 10° is 20°.

According to the law of reflection, the angle of incidence is equal to the angle of reflection. When a mirror is rotated, both the angle of incidence and the angle of reflection change. If the mirror is rotated by 10°, the angle of incidence changes by 10°, and since the angle of reflection is equal to the angle of incidence, the angle of reflection also changes by 10°. Therefore, the total change in the angle of reflection is 10° + 10° = 20°.

The electric field is constant and has a magnitude of 2kp / (3R) in the region of overlap.

Two spheres, each of radius R and carrying uniform volumetric charge densities of +p and -p, respectively, are placed so that they partially overlap.

If we draw a vector going from the center of the positive distribution to the center of the negative sphere and call this d (vector), show that the electric field in the region of overlap is constant.

Also, find its value.

The expression for the electric field between two charged spheres is derived as below:

Using Gauss's law,

we can calculate the electric field at a point p located at a distance r from the center of a uniformly charged sphere with radius R and volumetric charge density p0.

We must define an imaginary spherical shell (called a Gaussian surface) concentric with the charged sphere and with a radius of r.

The electric flux entering the Gaussian surface is E×4πr2,

where E is the electric field strength.

The total charge enclosed by the Gaussian surface,

q = (4/3)πr3ρ, is the volume of the Gaussian surface multiplied by the density of charge.

Using Gauss's law, the electric flux can be equated to the total charge divided by the permittivity of free space:

E×4πr2 = q/ε0.

The electric field at point P due to the positively charged sphere is directed away from it, and the electric field due to the negatively charged sphere is directed toward it.

If we take the vector D to be the distance between the centers of the two spheres, and r as the distance from P to the center of either sphere, the net electric field at point P is

\(E = k[(4/3)\)πρ\((R^3/r^2) + (4/3)\)πρ\((R^3/|D|^2)] D/|D|\)

The electric field inside the overlap region is constant, according to the formula given above.

The magnitude of the electric field in the region of overlap is proportional to the density of charge and inversely proportional to the square of the distance from the centers of the spheres.

E = 2kp/(3R)D/|D|

λ = c/f = \(\frac{3*10^{8} }{97.0*10^{6} } = 3.09m\)

Now we can calculate the phase difference:

Δx = \({(d^2+x^2)^0.5}-x\) =\([(9.30 m)^2 + (75.0 m)^2]^0.5 - 75.0 m\) ≈ 16.9 m

Δφ = 2πΔx/λ = 2π(16.9 m)/(3.09 m) ≈ 34.5 radians

The phase difference is a concept in physics that refers to the difference in the timing or position of two oscillations or waves. When two waves with the same frequency and amplitude are superimposed, they can either add constructively or destructively, depending on their phase relationship. If the waves are in phase, meaning their peaks and troughs line up perfectly, they will add constructively and result in a wave with twice the amplitude.

However, if the waves are out of phase, meaning their peaks and troughs do not align, they will add destructively and result in a wave with zero amplitude. Phase difference is usually expressed in terms of degrees or radians. A phase difference of 180 degrees (or pi radians) means that the waves are completely out of phase, while a phase difference of 0 degrees (or 2*pi radians) means that they are in phase.
