1 atm corresponds to 760 mmHg, so we can set up a simple proportion to find how many atmospheres correspond to 570 mmHg:
and from this, we find
Answer:
in co2 there is one atom of carbon
Explanation:
i don't know the anss , sorry.
Answer:
Explanation:
From the information given,
V = 4 volts
A = 2 amps
a)
In the first instance, one light on the sting goes out and the whole string of lights no longer turns on. This means that the circuit is a series circuit.
b) Total voltage = 4 x 100 = 400 V
The current passing through each bulb is the same. Thus
Total Current = 2 Amps
Recall, V = IR
R = V/I
Thus,
Resistance = 400/2
Resistance = 200 ohms
c) In this case, one light goes out on the string all other lights still turn on. This means that the circuit is a parallel circuit
d)
The voltage is the same
Total voltage = 4 volts
Total current = 2 x 100 = 200 amps
Total resistance = 4/200
Total resistance = 0.02 ohms
Answer:
-1.65
Explanation:
First of all, we find the position of the image by using the lens equation:
where:
f is the focal length of the lens
p is the distance of the object from the lens
q is the distance of the image from the lens
For the lens in this problem:
f = 21.0 cm (the focal length of a convex lens is positive)
p = 33.7 cm
Solving for q, we find the position of the image:
Then, the magnification of the image is given by:
And substituting,
Which means that the image is inverted (negative sign) and enlarged (because M is larger than 1).
