Answer:
Focal Length = 38.61cm, Power = 2.59 Diopter, Converging lens.
Explanation:
When an object is placed 25cm from Gbenga's eye, the glasses lens must produce an image 61cm away (Gbenga's eye near point).
An image 61cm from the eye will be (61cm - 1.6cm) from the glasses.
i.e. 
and 
note 
will be negative because the image is formed on the same side as the object.
finally, 
the formula for finding the focal length 
is given as
The focal length is positive which indicates converging lens
power 
but 
must be in metres
Therefore, 
Based on scientific data, the stone is accelerated at approximately 10 
.
<u>Given the following data:</u>
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.
This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.
<h3>Gravity on planet Earth</h3>
Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.
According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 .
In this scenario, the stone is accelerated at approximately 10 .

To maximize the power delivered to load, we should minimize the internal resistance which means option A is correct.
<h3>What is the relationship between the power and the internal resistance?</h3>
Power can be delivered to the internal resistance of a battery, but in a case whereby there is a decrease in the internal resistance will bring about the decrease in the lost power as well as the increase in the percentage of the power delivered to the device.
In this case, To maximize the power delivered to load, we should minimize the internal resistance
Therefore, Option A is correct.

Explanation:
La infección por Salmonella (salmonelosis) es una enfermedad bacteriana común que afecta el tracto intestinal. ... Los humanos se infectan con mayor frecuencia a través de agua o alimentos contaminados. Por lo general, las personas con infección por salmonella no tienen síntomas. Otros desarrollan diarrea, fiebre y calambres abdominales dentro de las ocho a 72 horas.
Answer: The frequency heard will be f = 275.675Hz
Explanation: When an object emitting sound is moving, it occurs a phenomenon called Doppler shift or Doppler effect. What happens is that the sound gets higher when the moving object comes closer the observer and becomes lower after it passes, This change is due to the quantity of waves that passes through an area in an unit of time.
The formula to calculate the Doppler effect is as follows
f = (
) · f₀
f is the observed frequency;
c is the speed of sound;
Vs is velocity of the source;
f₀ is the emitted frequency of source;
Substituting and calculating,
f = 
· 300
f = 275.675 Hz
Thus, the frequency heard by the police officer is 275.675Hz.
