A particle has a displacement of 12m towards east, then 5m towards north and then 6m vertically
upwards what is the magnitude of the sum of these displacements ?
1) 10.28m
2) 14.32m
3) 22.42m
4) 30.82m
Answer:
D = 14.31 m
Explanation:
It is given that,
Displacement due east is 12 m
Displacement due north is 5 m
Displacement in vertically upward direction is 6 m
We need to find the magnitude of the sum of these displacements. We know that, vertically upward, east and north are mutually perpendicular direction. So, the resultant is given by :
[tex]R=\sqrt{12^2+5^2+6^2} \\\\R=\sqrt{144+25+36} \\\\R=14.31\ m[/tex]
So, the magnitude of the sum of these displacements is 14.31 m.

If E=1/2Av^2+Bmx find the dimensions of A and B(Where E is energy,v,m and x are velocity,mass and distance respectively)
Answer:
A = [kg]
B = [m/s²]
Explanation:
E = ½ Av² + Bmx
Substitute the units:
[J] = ½ A [m/s]² + B [kg] [m]
A Joule written in base units is:
1 J = 1 Nm = 1 kg m²/s²
Each term must have the same units.
[kg m²/s²] = A [m/s]²
[kg m²/s²] = A [m²/s²]
A = [kg]
[kg m²/s²] = B [kg] [m]
B = [m/s²]

Answer:
Final velocity, v = 1.41 m/s.
Explanation:
It is given that,
Initial velocity of the basketball, u = 4 m/s
Acceleration of the ball, a = -0.5 m/s² (as it slows down)
We need to find the velocity of the basketball after rolling for 14 m. It is a concept of equation of motion in kinematics. Using third equation of motion as :
[tex]v^2=u^2+2ad[/tex]
v is final velocity
[tex]v^2=(4)^2+2\times (-0.5)\times 14\\\\v=\sqrt 2\ m/s\\\\v=1.41\ m/s[/tex]
So, the final velocity of the basketball is 1.41 m/s.

Polar bears are extremely good swimmers and can travel as long as 10 hours without resting. If a polar bear is swimming with an average speed of 2.6m/s how far will it have traveled after 10.0 hours? (Convert hours for seconds)
Answer:
It travels 93600 m
Explanation:
speed = 2.6 m/s
time = 10 hour
10 hour = 10 x 60 x 60 = 36000 s
distance = speed x time = 2.6 x 36000 = 93600 m
11 kg is a familiar weight for a bag of flour. You are baking cookies for a Save The Rain Forest fund drive. It takes 500 g of flour to make one batch of cookies. How many batches of cookies can you make with one bag of flour
Answer: 22 batches.
Explanation:
Given that 11 kg is a familiar weight for a bag of flour. Also, it is given that It takes 500 g of flour to make one batch of cookies.
How many batches of cookies can you make with one bag of flour
Let's first convert 11 kg into grams (g) by multiplying it by 1000
11 × 1000 = 11000 g
Divide 11000 by 500
11000/500 = 22
Therefore, 22 batches of cookies can be made with one bag of flour.
Anwer this quickly.... Find the equivalent capacitance of the following combination.
Answer:
When we have capacitors in series, with capacitances c1, c2, ...., cn, the total capacitance can be obtained from the equation:
1/ct = 1/c1 + 1/c2 + .......
When we have capacitors in parallel, with capacitances c1, c2, ..., cn, the total capacitance can be obtained from the equation:
ct = c1 + c2 +......
Ok, in this case we have two branches, and in each branch we have two capacitors in series.
So the capacitance of each branch will be:
1/ct = 1/c + 1/c = 2/c
ct = c/2.
Now we can think that we have two capacitors in parallel, each one with capacitance c/2.
So the total capacitance is:
ct = c/2 + c/2 = c.

What minimum separation between two parallel plates of glass (nglass =1.5) produces constructive interference for the reflected light with a 710 nm wavelength if the gap between the plates is filled with oil with noil =1.8?
Answer:
The value is [tex]t = 9.861 *10^{-8} \ m[/tex]
Explanation:
From the question we are told that
The refractive index of glass is [tex]n_{glass} = 1.5[/tex]
The wavelength is [tex]\lambda = 710 nm = \frac{710}{1 * 10^9} = 710*10^{-9} \ m[/tex]
The refractive index of oil is [tex]n_{oil} = 1.8[/tex]
Generally the condition for refractive index is mathematically represented as
[tex]2 * t = [m + \frac{1}{2} ] \frac{\lambda}{n_{oil}}[/tex]
Where t is the separation between two parallel plates of glass , now at minimum m which is the order of maxima produced is = 0
So
[tex]2 * t = [0 + \frac{1}{2} ] \frac{710 *10^{-9}}{1.8}[/tex]
[tex]t = 9.861 *10^{-8} \ m[/tex]

If the magnetic field is held constant at 3.0 T and the loop is pulled out of the region that contains the field in 0.2 s, what is the magnitude of the average induced emf in the loop
Answer:
emf = 15 * Area and if A is given in square meters, the units of the emf will be Volts
Explanation:
Assuming that the area of the loop of current (A) is known, the magnitude of the induced emf can be calculated using Faraday-Lenz's Law:
[tex]emf=|-\frac{\Delta\,\Phi}{\Delta \,t} |=|\frac{A\,B}{\Delta \,t}|=|\frac{A\,(3)}{0.2}|=15\,A[/tex]
and if the area (A) is given in square meters, the emf will directly come in units of Volts.

30 points plus brainliest for best answer no funny answers Assignment: Waves Concept Map Exploration Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. Include the following somewhere in your concept map: • types of energy transferred • medium required (if applicable) for transfer of energy • speed of energy transfer through various mediums (solid, liquid, gas) Concept Idea Bank: mechanical waves transfer light energy can pass through matter electromagnetic waves do not require a medium transfer sound energy require a medium travel is slowed as density of travel is faster as density of matter increases matter increases 1. Think about the kind of map that would be best to use to organize and compare mechanical and electromagnetic waves. 2. Review the rubric that will be used to grade this assignment. 3. Create your concept map. 4. When you have completed the concept map, don’t forget to submit it for a grade. Describe the functional relationship between the two quantities in the graph.
Answer:
Waves: "The phenomenon in which any number of particles or the energy packets that originates from a transmitter travels in a direction and it is somehow directed towards a receiver end is called as waves."
Electromagnetic wave: The type of waves which do not require any sort of medium for the transformation process of the energy, as it is directed towards from a transmitter towards a receiver.
For example: Radio, IR , Ultra sonic waves etc.
Mechanical waves: The type of waves which requires some medium to transfer the energy packets from one place to another, or from one point to the other using some medium. As the medium can be solids,liquids, or any gaseous forms.
For example: Sound waves, seismic waves etc.
Explanation:
The transfer of energy in Mechanical waves and Electromagnetic waves:
Both, the waves are much different due ones basic requirement of a medium while the other don't require one. As the density of any medium if increased it will increase the speed of the wave propagation. And this any medium being more denser will result in high speed form mechanical waves.
While, the electromagnetic waves can pass through matters or elements easily with out having any obstruction faced in its path because presence of medium is no requirement for the wave propagation.

While practicing S-turns, a consistently smaller half-circle is made on one side of the road than on the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in turn:_______
Answer:
The answer is "4-5-6 because the bank is growing too quickly in the beginning of its turn".
Explanation:
The S-turns is also known as the reference technique, in which the ground track of the aircraft on both sides of a defined ground-based straight-line distance represents 2 different but equivalent circles.
Throughout the S-turns, on either side of the road, a progressively smaller half-circle is formed, and this turn does not stop until the road or reference line is crossed during the early part of the turn, the twists increase too quickly.
Pendulum on a Fixed Pivot
Match each point from the pendulum to the correct percentage of PE.
3 points
0% 98% 100%
Point 1
Point 3
Point 5
Point 1
Point 3
Point 5
Answer:
Point 1. most extreme point. PE 100%
Point 3 point at mid-height PE 50%
Point 5 lowest point PE 0%
Explanation:
The energy in a pendulum is conserved if we ignore the friction of the air, the total energy is
Em = ½ k A²
at each point the energy can be written as a potential part and a kinetic part
Em = PE + K
where Pe is the potential energy and K the kinetic energy
In the entire trajectory the energy passes from one form to the other.
In general there are some points of very high interest.
Point 1. most extreme point in this case the pendulum is stopped and the
Em = PE 100%
Point 3. point at mid-height
Em = PE + K
at this point the energy is 50% of each
Point 5. lowest point, at this point the body has a height of ero so its potential energy is zero
Em = K 100%
potential energy is 0%
When kinetic and potential energy are equal???
Answer:
No there aren’t equal

A certain freely falling object, released from rest, requires 1.50 s to travel the last 30.0 m before it hits the ground. From what height above the ground did it fall
Answer:
The object fell from about 38.14 meters
Explanation:
We can use the formula for displacement under accelerated motion due to gravity to find the velocity of the object had 30 m before hitting the ground :
[tex]y_f-y_i=v_i * \,t-\frac{9.8}{2} \,t^2\\0-30=v_i \,(1.5)-4.9\,(1.5)^2\\-18.975=v_i\,(1.5)\\v_i=-12.65\,\,\frac{m}{s}[/tex]
Now, knowing this velocity, we can find the time it took to fall from the initial position to 30 m before hitting the ground:
[tex]v_f=v_i-g\,*\,t\\-12.65=0-g \,*\,t\\t=\frac{12.65}{g} \\t\approx1.29\,\,s[/tex]
And now we can find what is the total distance covered in 1.5 s plus 1.29 seconds for this free falling object:
[tex]y_f-y_i=v_i * \,t-\frac{9.8}{2} \,t^2\\0-y_i=0-\frac{9.8}{2} \,(2.79)^2\\-y_i=-38.14\\y_i=38.14\,\,m[/tex]
