#9). the <em>last </em>statement is true
Calculation using Ohm's Law:
It helps a lot if you know what Ohm's Law says.
It says: Current = (voltage) / (resistance)
Current = (500 volts) / (250 ohms)
<em>Current = 2 Amperes</em>
Answer:
A.
Explanation:
To solve this problem it is necessary to take into account the concepts related to angular velocity and centripetal acceleration,
from the cinematic equations of motion we know that
where,
V = Tangential Velocity
r = radius
Angular velocity
While the centripetal acceleration is given by
The displacement of the object is based on gravitational acceleration, so
a = g = 9.8 and the radius would be
Reemplazando:
Therefore the answer is A.
Answer:
e. all three objects possess charges of the same sign.
Explanation:
We know that objects with same polarity will repel each other while objects with opposite polarity will attract each other. Here objects A and B repel each other which means they possess the charge of same polarity. Objects B and C also repel each other which means that they also possess the same polarity (sign).
This means that A and C will also repel each other. All the three objects possess the charge with same polarity.
Answer:
The stickiness in the inner walls allows them to be easily coated with the desired antigens, this translates in the use of a smaller amount of antigen. If the walls weren't sticky there's a possibility the antigen won't stick to them and therefore the result of the ELISA can be a false negative.
