Answer:
a) i = -4.02 cm
, b) h’= 1,576 cm
Explanation:
a) The constructor equation is
1 / f = 1 / i + 1 / o
Where f is the focal length, i and o are the distance to the image and the object
Let's clear the distance to the image
1 / i = 1 / f - 1 / o
1 / i = 1 / -19 - 1 / 5.1
1 / i = 0.2487
i = -4.02 cm
b) let's use the expression of magnification
m = h’/ h = - i / o
h’= - h i / o
h’= 2.2 4.02 /5.1
h’= 1,576 cm
Answer:
10m/s^2
Explanation:
Force = mass x acceleration
Acceleration = force/ mass
= 20000000/2000000
=10m/s^2
<span>The last main subatomic particle to be discovered was the
antihelium-4. It was discovered on 2011
and it is measured and produces through the STAR detector. The Antihelium-4 was discovered accidentally
when an experiment was conducted. It is
also the first particle that was discovered by the means of experiment.</span>
My guesses would be g. or F
