A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour
Answer:
Hello your question is incomplete below is the missing piece
What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.
answer : 25.73 m/s
Explanation:
Given
V1 = 15 miles/hour = 6.71 m/s [ 45° EN ]
V2 = 18 m/s [ 5° NE ]
Calculate the resultant velocity
Vr = 6.71 m/s[45°] + 18m/s[5°].
Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )
Vr = ( 4.74 + 4.74 i )+ ( 17.93 + 1.57i) = 22.67 + 12.18i.
Therefore the magnitude
= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Motion is
displacement
an object you look at to determine if something is moving
a change of position in relation to another object
speed
Answer:
a change of position in relation to another object.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
Hence, motion is a change of position in relation to another object.
Which of the following would have the most momentum?
A. A train traveling 60 miles per hour.
B. A motorcycle traveling 60 miles per hour.
C. A car traveling at 60 miles per hour.
D. A basketball traveling 60 miles per hour.
Answer:
A. A train traveling 60 miles per hour.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
This ultimately implies that, the mass of an object or body is directly proportional to its momentum. Thus, the higher the mass of an object or body, the greater would be its momentum and vice-versa.
Hence, a train traveling 60 miles per hour would have the most momentum because it has the greatest mass among the other objects (options).
Richard Julius once made a model plane that could travel a max speed of 110 m/s. Suppose the plane was held in a circular path by a control line. Suppose the plane ran out of gas while moving at its maximum speed and Richard Julius pulled the line in to bring the plane home while it continued in a circular path. If the line's initial length is 120 m and Richard Julius shortened the line by 0.80 m every second, what was the plane's speed after 33.0 s?
Answer:
85.8 m/s
Explanation:
We know that the length of the circular path, L the plane travels is
L = rθ where r = radius of path and θ = angle covered
Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt
where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path
Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed and t = time,
θ = θ₀ + ωt = 0 + ωt = ωt
So, v = rdθ/dt + θdr/dt
v = rω + ωtdr/dt
v = (r + tdr/dt)ω
v = (r + tdr/dt)v'/r
v = v' + tv'/r(dr/dt)
v = v'[1 + t(dr/dt)/r]
Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)
So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]
v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]
v = 110 m/s[1 + 11.0 s(-0.02/s)]
v = 110 m/s[1 - 0.22]
v = 110 m/s(0.78)
v = 85.8 m/s

Hi people; there's a question that has been so confusing for me and a friend of mine.
0°C + 0°C = 64°F
Is this correct or wrong?
Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:
[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]
In our case x = 0, then y will be:
[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]
[tex]y=32^{\circ}F[/tex]
Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:
[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]
I hope it helps you!

You wake up in the morning and get out of bed. Does the floor feel cold or warm on your bare feet? On the lines below, write a sentence that compares how it feels to step on a bare floor and on a rug on a cold morning
When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn
We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.
What is heat transfer?Heat will be transfer on a temperature gradient from one substance to the other. Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.
Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum. At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.
A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.

Why does it take 2 days longer for the Moon to go from New Moon to New Moon when viewed form the Earth than it takes for the the moon to make 1 complete rotation on its axis?
The time between two new Moon phases or two full Moon phases is 29.5 days. ... The difference of 29.5 and 27.3 is that while the Moon is orbiting the Earth, the Earth is moving along in its orbit so it takes longer for the Moon to reach the same position relative to the Sun.

Conservation of momentum
Answer:
The combined velocity of Sally and the sled is 1.688 meters per second.
Explanation:
Let suppose that Sally collides inelasticly, meaning that final velocity of Sally-sled system can be determined solely by Principle of Momentum Conservation:
[tex]m_{S}\cdot v_{S, o} + m_{s}\cdot v_{s,o} = (m_{S}+m_{s})\cdot v[/tex] (1)
Where:
[tex]m_{S}[/tex] - Mass of Sally, measured in kilograms.
[tex]m_{s}[/tex] - Mass of the sled, measured in kilograms.
[tex]v_{S,o}[/tex] - Initial velocity of Sally, measured in meters per second.
[tex]v_{s,o}[/tex] - Initial velocity of the sled, measured in meters per second.
[tex]v[/tex] - Final velocity of the Sally-sled system, measured in meters per second.
If we know that [tex]m_{S} = 54\,kg[/tex], [tex]m_{s} = 10\,kg[/tex], [tex]v_{S,o} = 2\,\frac{m}{s}[/tex] and [tex]v_{s,o} = 0\,\frac{m}{s}[/tex], then the final velocity of the system is:
[tex]v = \frac{m_{S}\cdot v_{S,o}+m_{s}\cdot v_{s,o}}{m_{S}+m_{s}}[/tex]
[tex]v = 1.688\,\frac{m}{s}[/tex]
The combined velocity of Sally and the sled is 1.688 meters per second.

Oliver builds a circuit connecting a light bulb to a battery with wires, leaving a gap in one of the wires. He places several objects across the gap to close the loop. He wants to see which objects allow electricity to flow and turn on the light bulb. Why do some materials allow electricity to flow through while others do not?
A-Electricity will flow if the atoms in the material are bound tightly to each other.
B-Electricity will flow if the atoms in the material are bound loosely to each other.
C-Electricity will flow if the electrons are bound tightly to their atoms in the material.
D-Electricity will flow if the electrons are bound loosely to their atoms in the material.
Answer:
C-Electricity will flow if the electrons are bound tightly to their atoms in the material.
Explanation:
The flow of electricity through a material is determined by the condition of the electron which make of the atoms of the material. For example, in iron metal, the electron of the material is bounds tightly to their atoms. Do to this reason, the electricity can flow freely inside them unlike the plastic material which has no tightly bound electrons.

What is the acceleration of an object that goes from 45m/s to 10 m/s in 5 seconds?
Answer:
[tex]\boxed {\boxed {\sf a= -7 \ m/s^2}}[/tex]
Explanation:
Acceleration is the change in velocity over time.
[tex]a= \frac {v_f-v_i}{t}[/tex]
The object accelerates from 45 meters per second to 10 meters per second in 5 seconds. Therefore,
[tex]v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac { -35 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= -7 \ m/s/s[/tex]
[tex]a= -7 \ m/s^2[/tex]
The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
