Answer:
construct validity
Explanation:
According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question it seems that the researcher is using construct validity. This is the act of measuring or validating what the extent to which a claim is true. In this situation since the claim states that people involved in crimes tend to do speed and drugs, then the researcher compares the criminals responses to those areas to test the validity of the claim.

Answer:
Simply drop the egg from one inch above your foot and it will not break.
Explanation:
A transmission system at a radio station uses an oscillator
to convert a direct current into a high frequency alternating current. Direct
current or DC is the current in which the flow of the charge is one
directional. In case of alternating current or AC, the flow of the charge
reverses direction after a period of time.
<span>In regards to the second
question, a unit for measuring frequency is the hertz. So the correct answer to
the given question is option “B”. </span>
Explanation:
It is given that,
Earth's magnetic field, 
Direction of magnetic field, 67.1 degrees below the horizontal, with the horizontal component directed due north.
The magnetic force on the wire per unit length of wire, 
(a) The given scenario is shown in the attached figure as :
Using the right hand rule to find the direction of magnetic force on the wire. By using this rule, we get the magnetic force acting on the wire is in upward direction.
(b) Let I is the current flowing in the wire. The magnetic force is given by the following formula as:
I = 384.61 A
Hence, this is the required solution.
The answer is 80 J of electrical energy
