C) it decreased
because atmospheric pressure decreases as we move up.
Answer:
1) Yes the direction of the magnetic field is found based on Fleming's Right Hand Rule
2) The pattern indicates the direction of the magnetic force field lines
Explanation:
1) The solenoid is the is the coil of electric conductor that when it carries an electric current produces a magnetic field
According to Fleming's Right Hand Rule, the direction of the magnetic field produced by a solenoid, depends on the direction of the current such that when the direction of the conventional current is in the direction of the wrapped fingers, the thumb points in the direction of the magnetic field which is North N.
2) The pattern of field lines inside the solenoid indicates the direction of the generated magnetic field moving from left to right within the solenoid as the electric current moves around in the direction shown in the diagram.
We can look at all the ages of the earth since it’s a big crack is reveals many layers of the earth and we can know about chemicals and metals that were in earth and diffrent times
Answer:
a. 7.62cm
b. Real and inverted
c. 2.76 cm
d. 3450
Explanation:
We proceed as follows;
a. the lens equation that relates the object distance to the image distance with the focal length is given as follows;
1/f = 1/p + 1/q
making q the subject of the formula;
q = pf/p-f
From the question;
p = 4.70m
f = 7.5cm = 0.075m
Substituting these, we have ;
q = (4.7)(0.075)/(4.7-0.075) = 0.3525/4.625 = 0.0762 = 7.62 cm
b. The image is real and inverted since the image distance is positive
c. We want to calculate how tall the image is
Mathematically;
h1 = (q/p)h0
h1 = (7.62/4.70)* 1.7
h1 = 2.76 cm
d. We want to calculate the number of pixels that fit into this image
Mathematically:
n = h1/8 micro meter
n = 2.76cm/8 micro meter = 2.76 * 10^-2/8 * 10^-6 = 3450
