Given conditions:
height of object = 7.5cmdistance of object from mirror = 14 cmfocus length = -7 cmimage distance = ?
Using mirror formula:
1/(focus length) = 1/(object distance) + 1/(image distance)
or, -1/7 = 1/14 + 1/(image distance)
or, image distance = -4.66cm (the image formed is a virtual image)
Also, magnification of image is:
image height /height of object = - image distance /object distance
or, image height = - image distance / object distance * height of object
or, image height = -(-4.66) / 14 * 7.5 = 2.49 = 3(nearest whole number)
D. There's not enough research surrounding it. A big question is if they have side effects due to genetic modification that we don't know of.
(Not sure if you had D eliminated or? But it should be the correct answer)

<h2>
Hello!</h2>
The answer is 31.67 Amps.
<h2>
Why?</h2>
To solve the problem, we need to use Ohm's Law equation, which states that:

Where,
V, is the voltage (in volts)
I, is the current (in Amps)
R, is the resistance (in Ohms)
We are given the following information:

So, using Ohm's Law equation and substituting the given information, we have:

Hence, we have that the current used by the blender is 31.67Amps.
Have a nice day!
Answer:
60 kg
Explanation:
The man's weight is equal to the weight of the water he displaces.
mg = ρVg
m = ρV
m = (1000 kg/m³) (3 m × 2 m × 0.01 m)
m = 60 kg
The man's mass is 60 kg.
