Answer:

   v₀₂ = -2.67 m / s

Explanation:

Let's use the conservation of the moment, for this we define a system formed by the two cars.

Consider the north direction as positive and the subscript 1 will be used for car 1 and the subscript 2 for the second car

Initial instant. Before the crash

          p₀ = -m₁ v₀₁ + m₂ v₀₂

Final moment. Right after the crash

          p_f = (m₁ + m₂) v

           p₀ = p_f

           -m₁ [tex]v_{o1}[/tex] + m₂ v_{o2} = (m₁ + m2) v_{f}

         v₀₂ = [tex]\frac{(m_1 +m_2) v }{m_2}[/tex]+  [tex]\frac{m_1 v_{o1} }{m_{1} }[/tex]

let's calculate

          v₀₂ = [tex]\frac{(1800 +2800) 5.22 + 1800 (-17.5)}{2800}[/tex]

          v₀₂ = -2.67 m / s

the negative sign indicates that the carriage moves in the opposite direction of the temperies

Answer:

The most correct option for the magnitude of the velocity of the ship relative to the port is;

33 km/h

Explanation:

The given parameters of the cargo ship are;

The speed of the cargo ship = 25 km/h

The direction of the cargo ship, θ₁ = 20° North of East

The speed of the current = 10 km/h

The direction of the current, θ₂ = 15° North of East relative to the port

Therefore the direction of the ship relative to the port, 'θ', is given as the sum of θ₁ and θ₂ as follows;

θ = θ₁ + θ₂ = 20° + 15° = 35°

The component of the velocities relative to the port are given as follows;

The velocity of the ship, v₁ = 25·cos(35°)·i + 25·sin(35°)·j

The velocity of the current , v₂ = 10·cos(15°)·i + 10·sin(15°)·j

The velocity of the ship relative to the port, v = (25·cos(35°) + 10·cos(15°))·i + (25·sin(35°) + 10·sin(15°))·j

∴ v ≈ 30.14·i + 16.93·j

The magnitude of 'v' is [tex]\left | v \right |[/tex] = √(30.14² + 16.93²) ≈ 34.6

Therefore, the magnitude of the velocity of the ship relative to the port, [tex]\left | v \right |[/tex] ≈ 34.6 km/h.

Therefore, the closest correct option for the velocity of the ship relative to the port is 33 km/h

Answer:

The correct option for the magnitude of the velocity of the ship relative to the port is...

(33 km/h)

Answer: Chloroplast

Explanation: Chloroplasts work to convert the Sun's light energy into sugars that cells can use. It's like a solar panel that converts energy from sunlight into electric power.

The Moon spins in space in a movement called rotation. Oddly enough, it also takes the Moon about 27 days to spin around once (which is much slower than Earth's rotation, which only takes 24 hours). That means the Moon goes all the way around Earth in the same amount of time it takes to spin around just once!

Answer:

Dorsal side:B

Ventral side:D

Anterior end:A

Posterior end:C

Explanation:

The four regions of the earthworm are, A is the anterior end,B is the dorsal side, C is the posterior end, and D is the ventral side.

Earthworms are common soil dwellers who are both safe and useful. Earthworms help plants flourish by collapsing dead and decaying organic debris into rich humus soil.

They also aerate the soil and enhance flow by digging small canals and holes.

The four regions of the earthworm are;

A is the Anterior end

B is the Dorsal side

C is the Posterior end

D is the Ventral side

Hence all the regions are clearly defined with the help of digrame.

Answer:

C

Explanation:

Electromagnetic waves are produced by the vibration of charged particles.

The true statement of an electromagnetic wave is option c. The wave is caused by vibrating particles of matter.

It is the wave that should be developed that leads to the vibration that lies between the electric field and a magnetic field.

Here EM waves should be composed for oscillating magnetic and electric fields.

Hence, the option c is correct.

Explanation:

People are wild about amusement parks. Each day, we flock by the millions to the nearest park, paying a sizable hunk of money to wait in long lines for a short 60-second ride on our favorite roller coaster. The thought prompts one to consider what is it about a roller coaster ride that provides such widespread excitement among so many of us and such dreadful fear in the rest? Is our excitement about coasters due to their high speeds? Absolutely not! In fact, it would be foolish to spend so much time and money to ride a selection of roller coasters if it were for reasons of speed. It is more than likely that most of us sustain higher speeds on our ride along the interstate highway on the way to the amusement park than we do once we enter the park. The thrill of roller coasters is not due to their speed, but rather due to their accelerations and to the feelings of weightlessness and weightiness that they produce. Roller coasters thrill us because of their ability to accelerate us downward one moment and upwards the next; leftwards one moment and rightwards the next. Roller coasters are about acceleration; that's what makes them thrilling. And in this part of Lesson 2, we will focus on the centripetal acceleration experienced by riders within the circular-shaped sections of a roller coaster track. These sections include the clothoid loops (that we will approximate as a circle), the sharp 180-degree banked turns, and the small dips and hills found along otherwise straight sections of the track.

The correct option is (d).

Angle should be 180° between the direction of force and the direction of motion of a body as work done is equal to force multiplied by displacement multiplied by cosx.

Answer:

The jet stream speed used by the computer is 142.[tex]\overline {857142}[/tex] km/h

Explanation:

The given parameters are;

The distance between the two cities the plane flies = 4,000 km

The difference in flight times for outgoing and return flights = 70.0 min

We note that 70 min = 70 min × 1 h/60 min = 7/6 h

The airspeed recommended by the airline computer = 1,000 km/h

Let 'a' represent the jet stream speed

The time it takes the plane moving in the same direction as the jet stream between the two cities, 't₁', is given as follows;

[tex]t_1 = \dfrac{4000}{1000 + a}[/tex]

The time it takes the plane moving in the opposite direction as the jet stream between the two cities, 't₂', is given as follows;

[tex]t_2 = \dfrac{4000}{1000 - a}[/tex]

The difference in flight times for outgoing and return flights, Δt = t₂ - t₁

Therefore, we have;

[tex]\Delta t = t_2 - t_1 = \dfrac{4000}{1000 - a} - \dfrac{4000}{1000 + a} = \dfrac{7}{6}[/tex]

From which we get;

[tex]-\dfrac{8000 \cdot a}{a^2 -1,000,000} = \dfrac{7}{6}[/tex]

By cross multiplying, we have;

-48,000·a = 7·a²- 7,000,000

∴ 7·a² + 48,000·a - 7,000,000 = 0

Factorizing with a graphic calculator gives;

(7·a - 1,000)·(a + 7,000) = 0

∴ a = 1,000/7, or a = -7000

Therefore, the jet stream speed the computer is using, a = 1,000/7 km/h = 142.[tex]\overline {857142}[/tex] km/h.

The wave diagramed in blue.

Explanation:

The reason for this is because frequency is explained as the number of times something has occurred in a certain period of time.

Here, we are talking about wavelength, so the frequency is the number of times the wave can oscillate in this time length.

Say we make dots on the middle of each downward slope. How long does it take to get to each dot compared to the other diagram? The answer is the one with the least amount of time. The wave diagramed in blue.

To answer this equation, SUVAT is your best option utilizing and rearranging the known values to solve for the unknown.

here we have the values for

s=895

u=22

v=35

t= the unknown value

in this instant the equation s=0.5 x (u+v)t is the best equation to use

so we sub in the known values

895=0.5 x (22+35)t

rearrange to solve for t

895=28.5t

895/28.5=t

t=31.404 seconds (rounded to 3 decimal places)
