The diameter of Circle A is _________. EF AG EG FG
Answers
Answer:
The diameter is EF
Explanation:
Given
Circle A (See attachment)
Required
Determine the line that represents the diameter
First, it should be noted that the diameter of a circle is always a straight line.
From the attachment, the circle has the following straight lines:
E FE AA GA FIt should also be noted that the diameter passes through the center of a circle and divides it into two congruent parts.
From the list of straight lines above, only line EF satisfy this property
Hence, the diameter of the circle is line EF.

An electric heater is rated at 1500 W. If the heater is rated as 80% efficient, calculate the output
rate of energy
Answers
Answer:
Power = 1200 [W].
Explanation:
The efficiency of an electrical equipment is defined as the relationship between the power realized, over the power that is consumed. For this case, they give us the data of consumed power and efficiency in this way we can calculate the power that the equipment performs.
[tex]Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W][/tex]
This means that of the 1500 [W], 1200 [W] are actually used to get the job done. This is established by means of the first law of thermodynamics.

is done in displacing the body through a distance of 10m in the
direction of force?
Answers
Force = Work/distance
Force = 150/10
= 15 Newtons
Force = 15 Newtons
Therefore, 15 newtons of force is applied to the body when 150 joules of work
is done in displacing the body through a distance of 10m in the direction of the force.

Answers
Answer: 500 ft
Explanation:
High beam headlights help one to see better at night as the range of vision is greatly expanded. They can however, blind drivers coming on the opposite lane.
It is therefore prudent to ensure that when using high beam headlights, you dim them when a car is coming towards you. The appropriate distance to do so is a minimum of 500 ft from the car.

Answers
Answer:
3 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 2 L
Initial pressure (P₁) = 0.75 atm
Final pressure (P₂) = 0.5 atm
Final volume (V₂) =?
Using the Boyle's law equation, the new volume (i.e final volume) of the Ne gas can be obtained as:
Initial volume (V₁) = 2 L
Initial pressure (P₁) = 0.75 atm
Final pressure (P₂) = 0.5 atm
Final volume (V₂) =?
P₁V₁ = P₂V₂
0.75 × 2 = 0.5 × V₂
1.5 = 0.5 × V₂
Divide both side by 0.5
V₂ = 1.5 / 0.5
V₂ = 3 L
Thus, the new volume of the Ne gas is 3 L

We then have to identify each specie in the reaction equation. The reactants are;
Magnesium oxide and carbon
The products are
Carbon dioxide and magnesium metal
So the word equation is as follows;
Magnesium oxide + carbon ----> carbon dioxide + magnesium
In a sentence form;
One mole of magnesium oxide reacts with one mole of carbon to yield one mole of carbon dioxide and one mole of magnesium metal.
A child tugs on a rope attached to a 0.62 kg toy with a horizontal force of 16.3 N. A puppy pulls the toy in the opposite direction with a force of 15.8 N. What is the acceleration of the toy
Answers
Answer:
[tex]a=51.77\ m/s^2[/tex]
Explanation:
Given that,
The mass of a toy, m = 0.62 kg
Force with which a child pull the toy = 16.3 N
The force with which the toy pulled in the opposite direction = -15.8 N
We need to find the acceleration of the toy. Let F be the net force acting on the toy. It is equal to :
F = 16.3 N - (-15.8 N)
= 32.1 N
Let a be the acceleration of the toy. Using Newton' second law of motion to find it.
F = ma
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{32.1}{0.62}\\\\a=51.77\ m/s^2[/tex]
So, the acceleration of the toy is [tex]51.77\ m/s^2[/tex].

Answers
Answer:
True
Explanation:
It is true that you will feel a gentle pulling sensation in the muscle being stretched when Static stretching is done by slowly moving a joint.
What is static stretching?Static stretching is most likely the most well-known and time-honored method of stretching. This entails extending a muscle to its maximum length and then maintaining that position for at least 15 to 20 seconds.
With each stretch, the emphasis is frequently on focusing on a specific muscle group.
Hence it is true that you will feel a gentle pulling sensation in the muscle being stretched when Static stretching is done by slowly moving a joint.

1. How much heat is produced if you heat .25 kg water from 25 degrees C to 100 degrees C. The specific heat of water is 4180 J/kg C.
Answers
Answer:
Q = 78375 [J]
Explanation:
To solve this problem we must use the following ideal equation for the thermal energy of an element or substance depending on the temperature change.
[tex]Q=m*C_{p}*(T_{final}-T_{initial})[/tex]
where:
Q = heat [J]
m = mass = 0.25 [kg]
Cp = specific heat = 4180 [J/kg*C]
Tinitial = 25[°C]
Tfinal = 100 [°C]
[tex]Q =0.25*4180*(100-25)\\Q = 78375 [J][/tex]
HELP!! I need an explanation for this question!
Answers
Assuming a constant force, and hence a constant acceleration a, we have by Newton's second law,
4.0 N = (1.2 kg) a → a = (4.0 N) / (1.2 kg)
and by definition of average velocity,
a = (5.0 m/s - 2.0 m/s) / t
where t denotes the time for which the force is applied.
So,
(4.0 N) / (1.2 kg) = (3.0 m/s) / t → t = (3.0 m/s) (1.2 kg) / (4.0 N) = 0.90 s

Hubble features a 2.4 meter mirror, and it’s four main instruments observed in the ultraviolet, visible, and near in-fraired regions of the electromagnetic spectrum.
Hobbles orbit outside the distortion of earths atmosphere allows it to capture extremely high resolution images with the substantially lower background light than ground base telescopes. it has recorded some of the most detailed visible light images, allowing a deep view into space. Many Hubble observations have led to the breakthroughs in astrophysics, such as determining the right of expansion of the universe.
The Hubble telescope was built by the United States space agency NASA with the contributions from that European space agency. The space telescope science Institute select hobbles targets and processes the resulting data while Goddard space flight Center controls the spacecraft. Space telescope for repost as early as 1923. Hubble was founded in 1970s with the proposed launch in 1983, but the project was reset by technical delays, budget problems, and the 1986 challenger disaster. It was finally launched by space shuttle discovery in 1990, but its main mirror had been ground incorrectly, resulting in spherical aberration that can promise to telescopes capabilities. The optics were corrected to their intent to quality by a servicing mission in 1993. How old is only telescope designed to be maintained in space by astronauts. Five space shuttle missions have repaired, upgraded, and replace systems on the telescope, including all five of the main instruments. The first mission was initially canceled on safety grounds following the Columbia disaster which was in 2003, but nice administrator Michael D Griffin approved the fifth servicing mission which was completed in 2009. The telescope was opening as of April 24, 2020 is 30th anniversary, and could last until 2030-2040. One successor to the Hubble telescope is the James Webb space telescope which is scheduled to be launched in late 2021.
what is potential displacement?
Answers
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"potential displacement"
in geometry and mechanics a displacement is a vector whose length is a shortest distance from the initial to the final position of a point p undergoing motion.it quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory.A displacement may be identified with the translation that maps the initial position to the final position.
A displacement ,may also described as a relative position that is as the final position xf of the point to the point relatively to its initial position xi.The corresponding displacement vectors can be defined as the difference between the final and initial positions.
s=xf-xi=Δx
in considering motion of objects over time,the instantaneous velocity of the object is the rate of change of the displacement as a function of time.The instantaneous speed then is distinct from velocity or the time rate of change of the position vector.if one considers a moving initial position or equivalently a moving origin.
From motion over a given interval of time,the displacement divided by the length of the time interval defines the average velocity which is a vector and differ thus from the average speed,which is a scalar.
