Answer:
The answer is Top-Down processing
Explanation:
I had this question on a apex quiz and i got it correct.
Answer:
The correct answer will be-
1. Allows scientists to replicate experiments
2. Tests only one variable at a time
3. Plans how to record data so they can be published
Explanation:
A scientific experiment is performed to test the hypothesis which represents the limited explanation of the phenomenon.
The experiment is designed in a way that it test one variable at a time like the growth of plants. The experiment must be designed in a way that it can be replicated to reduce the error and repeated by other scientific persons to support the experiment. The design includes the plan for recording the results as it is one of the steps of the scientific method.
Thus, the selected options are the correct answer.
Controlled experiment is the type of experiment that involves changing only one variable at a time. Controlled experiment is subtly defined as an experiment which holds everything constant except one particular variable. This type of experiment allows only one variable to ever change at a given time
Answer:
C. perpendicular to one another and perpendicular to the direction of wave propagation.
Explanation:
An Electromagnetic wave (EM wave) is a wave having both electric and magnetic components in it. These wave radiates electromagnetic energy while propagating through the space. The electric and magnetic field component of the wave have an angle of 90° to each other aming them perpendicular while they both are perpendicular to the direction of wave propagation as well.
Some examples of EM waves are: UV rays, IR radiation, Radio waves etc. These waves propagate at the speed of light in vacuum.
Answer:
l3/l = 2
Explanation:
Suppose B1 is the magnetic field due to cable 1 and B2 is the field due to cable 2. Therefore, the magnitude of the field at a distance from the cable is equal to:
B = (uo*I)/(2*pi*r)
B1-2 = (B1^2 + B2^2)^1/2 = ((((uo*I)/(2*pi*r)^2 + (uo*I)/(2*pi*r)^2))))))^1/2 = (2^1/2)*(uo*l)/(2*pi*r)
From this equation we can say that the direction of the field will be from the corner that is empty and cable 3:
B3 = B1-2
(uo*l3)/(2*pi*(2^1/2)*r = (2^1/2)*(uo*l)/(2*pi*r)
From here we have that the relationship between both currents will be equal to:
l3/l = 2
Capillarity "Capillarity causes the part of the surface of a liquid in contact with a solid, to be either elevated above (e.g. water), or depressed below (e.g. mercury), the rest of the surface. This trait is named for the behaviour of liquids in capillary tubes placed perpendicular to the surface. The forces operating within capillarity are cohesion, adhesion, and surface tension."
