Jamie had a solid, angular crystal and noticed that it was very hard to break. Which model could represent the crystal?

Answer:

1. Distance travelled = 12 km.

2. Displacement = 8.6 km

Explanation:

From the question given above, the following data were obtained:

Distance 1 (d₁) = 7 km

Distance 2 (d₂) = 5 km

Total distance =?

Displacement =?

1. Determination of the distance travelled.

Distance 1 (d₁) = 7 km

Distance 2 (d₂) = 5 km

Total distance (dₜ) =?

dₜ = d₁ + d₂

dₜ = 7 + 5

dₜ = 12 km

2. Determination of the displacement.

In the attached photo, R is the displacement.

We can obtain the value of R by using the pythagoras theory as illustrated below:

R² = 7² + 5²

R² = 49 + 25

R² = 74

Take the square root of both side

R = √74

R = 8.6 km

if 3kg moves at 4.50 so 50 is 225

Answer:

position 4

Explanation:

if the north is tilted away it gets no sunlight, so its winter

It is winter in North America in position 4 because North America is tilted away from the Sun.

The "cycle of seasons" is caused by the occurrence of each season one after the other throughout the year. The seasons are also influenced by variations in the atmosphere, air vapour, wind, and precipitation.

A season other than summer and winter is created when rain falls continuously throughout a certain time. Other than summer and winter, seasons are seen to occur in different regions due to the local conditions.

As shown in the figure, at position 4,  North America is tilted away the Sun, the sun light falls on America  in tilted  manner. Hence, It is winter in North America in position 4. Whereas at position 2,  North America is tilted towards the Sun and It is summer in North America in position 2.

Answer:

relative positions of Earth, the Moon and the Sun.

Explanation:

A lunar eclipse is a phenomenon that occurs when the Earth comes between the Moon and the Sun thereby causing it to cover the Moon with its shadow.

Simply stated, lunar eclipse takes place when the Moon passes or moves through the Earth's shadow thereby blocking any ray of sunlight from reaching the Moon. Thus, the full moon appears deep red (blood moon).

Also, a lunar eclipse would occur only when the Sun, Earth, and Moon are closely aligned to form a straight line known as the syzygy.

There are three (3) types of lunar eclipse and these are;

1. Total lunar eclipse.

2. Partial lunar eclipse.

3. Penumbra lunar eclipse.

Hence, the changing appearance of the Moon during the lunar cycle is the result of the changing relative positions of Earth, the Moon and the Sun.

Answer:

Potential energy of spring = 24 Joules.

Explanation:

Given the following data;

Spring constant = 85N/m

Extension, e = 0.75m

Mass = 25kg

To find the potential energy of a spring

Potential energy of a spring is given by the formula;

P.E = ½ke²

Substituting into the equation, we have

P.E = ½*85*0.75²

P.E = 42.5 * 0.5625

P.E = 23.91 ≈ 24 Joules

P.E = 24 Joules

Answer:

The answer is below

Explanation:

Gravitational Potential energy is the energy stored by an object as a result of its vertical position or height.

Kinetic energy is the energy an object possesses due to its motion.

The law of conservation of energy states that energy cannot be created or destroyed but can be transformed from one form to another.

As the car accelerates down the hill, there is a change in gravitational potential energy as a result of  decrease in vertical height. Some of the gravitational potential energy would be changed into work done by friction while the rest would cause an increase in kinetic energy due to the car acceleration. Lastly, when the brake is applied to stop the car, the car would lose its kinetic energy.

Answer:

a) 2.2*10^7 N/C

b) 60 N/C

Explanation:

To start with, we say that the

Area charge of the plate, σ = q/2A

σ = 5.6*10^-6 / 2(12*10^-2)²

σ = 5.6*10^-6 / 0.0288

σ = 1.944*10^-4 C²/m

Next, we find the electric field

Electric field, E = σ/Eo

Electric field, E = 1.944*10^-4 / 8.85*10^-12

Electric field, E = 2.2*10^7 N/C

b)

E = kq/r²

E = [8.99*10^9 * 5.6*10^-6] / 29²

E = 50344 / 841

E = 60 N/C

This means that the E at a distance of 29 m is 60 N/C

Answer:

Eliza’s suggestion is the most promising

Explanation:

Newton’s law of universal gravitation is [tex]F = G\frac{m_1m_2}{r^2}[/tex] where G is a constant and both masses are constant in this experiment as well. So it only depends on r, the distance between the center of mass of both objects.

Bringing it high in the sky, as Flo suggests, is definitely not a good idea because it only increases the distance from the center of the Earth mass.

A mountain contains significant mass, so the center of the Earth mass is somewhat shifted to regions with the largest mountains. However, standing on top of a mountain, as Lorenzo suggests, doesn’t help since the shift of the center of mass, if any, is far smaller than the height of the mountain.

Standing near sea level, as Eliza suggests, is a good way to minimize the distance to the center of the Earth mass.

Answer:

a)  h = 53.8 m,  b)   h_minimum = 28 m, h_maximum = 63.3 m

Explanation:

a) For this exercise let's use Bernoulli's equation.

The subscript 1 is for the tank and the subscript for the building

          P₁ + ½ ρ g v₁² + ρ g y₁ = P₂ + ½ ρ g v₂² + ρ g y₂

In general, the water tanks are open to the atmosphere, so P1 = Patm, also the tanks are very large so the speed of the water surface is very small v₁=0 and as they give us the precious static, this it is when the keys are closed so the output velocity is zero, v₂= 0. The height of the floors in a building is y₂ = 12 m

we substitute in Bernoulli's equation

         P_{atm} + 0 + ρ g h = P₂ + 0 + ρ g y₂

         h = [tex]\frac{(P_2 - P_{atm}) + \rho \ g \ y_2}{\rho \ g}[/tex]

         h = [tex]\frac{\Delta P}{\rho g}[/tex] + y₂

indicate that the value of ΔP = 410 10³ Pa

we calculate

           h = 410 10³ / (1000 9.8) + 12

           h = 53.8 m

b) ask for the height range for the minimum and maximum pressure

            h =[tex]\frac{\Delta P}{\rho g}[/tex] ΔP / rho g

minimum

           h_minimum = 275 103/1000 9.8

           h_minimum = 28 m

maximums

           h_maximo = 620 103/1000 9.8

           h_maximum = 63.3 m

Complete question:

Consider the hypothetical reaction 4A + 2B → C + 3D

Over an interval of 4.0 s the average rate of change of the concentration of B was measured to be -0.0760 M/s. What is the final concentration of A at the end of this same interval if its concentration was initially 1.600 M?

Answer:

the final concentration of A is 0.992 M.

Explanation:

Given;

time of reaction, t = 4.0 s

rate of change of the concentration of B =  -0.0760 M/s

initial concentration of A = 1.600 M

⇒Determine the rate of change of the concentration of A.

From the given reaction: 4A + 2B → C + 3D

2 moles of B ---------------> 4 moles of A

-0.0760 M/s of B -----------> x

[tex]x = \frac{4(-0.076)}{2} \\\\x = -0.152 \ M/s[/tex]

⇒Determine the change in concentration of A after 4s;

ΔA = -0.152 M/s  x 4s

ΔA = -0.608 M

⇒ Determine the final concentration of A  after 4s

A = A₀ + ΔA

A = 1.6 M + (-0.608 M)

A = 1.6 M - 0.608 M

A = 0.992 M

Therefore, the final concentration of A is 0.992 M.

Answer:

the equations of motion can be separated into an equation that depends on a single variable.

Explanation:

he one-dimensional kinematics equations can be applied to two-dimensional systems because we can write the equations in such a way that each one of them depends on variables in a single dimension plus time, which, because it is a scalar, can be used in all dimensions.

A mathematical way of saying this is that the equations of motion can be separated into an equation that depends on a single variable.
