in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)

Please help me with a speech.The topic of my speech is Passion.
Answer:
Explanation:
Passion
For me, standing on the summit of Mt Everest was the result of following a process. The process of mountaineering. I love mountaineering. I am passionate about it. I love the months of planning for an expedition, the months of sweating and training to prepare my body physically. The meticulous preparation of my equipment. Most of all I love the huge mental challenge I have to overcome before each climb to confront my own fear. All these reasons are why I climb, they are why I climbed Mt Everest and that is why I continue to climb.
Passion is an enormously powerful force. It gives us the strength to get through hard times and setbacks. It gives us strength to overcome our fears, to ignore what other people think of us, to be disciplined and make sacrifices in pursuit of our dreams. Passionate people do not want to take shortcuts – they consider that ‘learning the process’ is an important part of the journey.
In mountaineering it’s easy to spot those who are not passionate about the process. They want to stand on top of the mountain but they are not really interested in the process of climbing the mountain. I feel for these people. Success without hard work is a hollow, empty feeling. They never last long in the sport.
Just as in life, successful mountaineers are the ones who are passionate. They are not there just to stand on the summit. Their passion gives them the energy to work the hardest, fight the longest, and in the words of Winston Churchill “never, never. never give-up”.
Identifying Obstacles
Since the purpose of these strategies is to help overcome obstacles and set-backs in your exercise routine, take a minute and think about the most obvious obstacle you have. If you do not have any obstacles at the present time, think about a potential obstacle to your exercise that could occur.

What is the unit for efficiency?
What is the biggest number the
efficiency can be?
How do you work out the % efficiency?
Answer:
Efficiency has no physical units (example .85 = 85%)
The largest number would be 1 or 100%
An example of efficiency is: work out/work in
or (work in - work lost to friction) / work in would be an example of the efficiency of the process

A student walks 3 km in 30 minutes. What is the student's average speed in km/h?
Answer:
6km/hr
Explanation:
3km = 30mins
x(km) = 1hr
1hr = 60 x 60 = 3600secs
30min = 30 x 60 = 1800secs
3 x 3,600/x X 1,800
x = 10,800/1,800
x = 6km/hr
To solve the problem we must know about speed, distance, and time.
What is the relationship between Speed, distance, and Time?
We know that speed, distance, and time all are in a relationship with each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
A student walks 3 km in 30 minutes.
We know distance can be written as the product of speed and time, therefore,
[tex]\rm Distance = \rm speed \times \rm Time[/tex]
Substituting the values we get,
[tex]\rm 3\ km = Speed \times 0.5\ hour[/tex]
[tex]\rm speed = \dfrac{3\ km}{0.5\ hour}[/tex]
speed = 15 km\h
Hence, the speed of the student is 15 km\hour.

The vertical columns on the periodic table of elements are called groups.
A True
B. False
Answer:
True
Explanation:
A girl who is watching a plane fly tells her friend that the plane isn't moving at all. Describe a frame of reference in which the girl's description would be true.
The girl's reference frame must be moving with the same speed as the plane.
If an observer is stationary and he watches a car moving he can observe that the car has a momentum and is moving with certain speed. But if the observer is in the car or moving with same speed, the car does not appear to move away form the observer. Likewise, two observers moving with different speed will have different observation about the same car.
Similarly, if the girl describes the plane is not moving that means either she is in the plane or moving with the same speed along with the plane.

A car is traveling at 120 kilometers per hour with 35,000 joules of kinetic energy on the freeway when it suddenly applies its brakes and comes to a screeching stop. How much of the original 35,000 joules of energy is left?
Answer:
0 J is left (No amount of the original 35000 J energy is left)
Explanation:
From the question
Kinetic Energy (K.E) = 1/2mv²................... Equation 1
Where m = mass of the car, v = velocity of the car.
make m the subject of the equation.
m = 2K.E/v²..................... Equation 2
Given: K.E = 35000 Joules, v = 120 km/h = (120×3600/1000) = 432 m/s
Substitute these values into equation 2
m = (2×35000)/432²
m = 0.375 kg.
If a brake is suddenly apply,
Then, the velocity of the car = 0 m/s.
Therefore,
K.E = 1/2(0.375×0²)
K.E = 0 J.
From the baove analysis, No amount of the original 35000 J energy is left.

Most metallic elements, such as copper
and iron, have high melting points. This
is a useful property because
F. it keeps cars made of metal from
becoming hot on summer days
G. it enables people to use pots and pans
made of metal to cook food
H. it prevents machine parts made of
metal from rusting
J. it makes metals easier to melt so they
can be poured into molds to make
precision tools
Answer:
G. it enables people to use pots and pans made of metal to cook food
Explanation:
Metals are known to be substances with a relative high melting point, which means that it takes a very high temperature to melt them. As used in this question, copper (Cu) and iron (Fe) at metallic elements that have high melting points.
One advantage of this property based on the options provided is that "it enables people to use pots and pans made of metal to cook food". This is because cooking food requires subjecting them to a constant temperature from a heat source e.g cooker or stove.
The material used to hold the food being cooked must possess a very high melting point to withstand the heat, hence, the importance of these metallic substances. Most pots and pans are made of steel, an alloy of iron, hence, they have high melting point.

The displacement current density between the plates of a parallel-plate capacitor is uniform and has a magnitude of 19.9 A/m2 as the capacitor is being charged. What is dE/dt, the rate at which the electric field strength is changing between the plates
Answer:
[tex]\dfrac{dE}{dt} \approx 2.261 \overline {36} \times 10^{12} \ V/ms[/tex]
Explanation:
The parameters given in the question are;
The magnitude of the displacement current density between the plates of a parallel-plate capacitor, J = 19.9 A/m²
We have;
[tex]i_d = \epsilon _0 \times \dfrac{d \Phi_E}{dt} =\epsilon _0 \times A \times \dfrac{d E}{dt}[/tex]
Therefore;
[tex]\therefore \dfrac{dE}{dt} =\dfrac{i_d}{\epsilon _0 \cdot A} =\dfrac{J}{\epsilon_0} = \dfrac{19.9}{8.8 \times 10^{-12}} \approx 2.261 \overline {36} \times 10^{12}[/tex]
Therefore;
[tex]\therefore \dfrac{dE}{dt} \approx 2.261 \overline {36} \times 10^{12} \ V/ms[/tex]
