Answer:
d. add another d-cell to the circuit
Explanation:
To make the electromagnet pick something, the student should add another d-cell to the circuit.
Simply, the electromagnet set up is generating very weak magnetic fields.
- To produce an electromagnet, there must be an interaction between electric fields an conductor.
- As the wire turns around in the vicinity of the electric field, it induces magnetism.
- The number of turns of wire here is pretty considerable.
- But the electric field is very weak.
- Additional d-cell in the circuit will circumvent this problem
Compounds that are formed when two or more atoms combine to form molecules are called Molecular Compounds.
C.
Matter can not be created or destroyed, so in a closed system it stays constant
<span>One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to write. First, look at the degrees for each term in the expression.</span> and in this way you will be able to write polynominal in standard form.
Answer:
NaF-basic
NH4Cl-acidic
KI-neutral
NH4F-acidic
Explanation:
To find the pH of a salt solution, one has to find the relative strength of the conjugated acid-base pair of the solution. A salt may be labelled acidic when it contains a H group, and a basic salt contains a OH group.
