Which diagram shows a situation that would not produce an electric current in the wire?
Answers
Answer:B
Explanation:
A P E X
The diagram in which there is no current in the electric wire is B, the reason behind that it is not connected with the battery.
What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
The second diagram from the option will have no current in it because the wires are not connected with the battery, so the flow of current will not take place.

In addition to how much force Earth exerts on the object, which features of an object affect its weight?
A.mass and location of the object
B.shape and location of the object
C.location of the object and how much energy the object has
D.mass of the object and how much energy the object has
Answers
Answer/Explanation:
The weight of an object is defined as the force that is exerted due to the gravitational force.
Mathematically, it can be written as :
W = m g
Where
m is the mass of the object
g is the acceleration due to gravity
Also,
We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.
The feature of an object that affects its weight are :
Mass of the object
Location of the object

How can shorter string produce more fundamental frequency in two string of different length?
Answers
Answer:
Shorter string produces more frequency in two different strings because the equation for frequency is velocity/wavelength , this means that a shorter string creates a shorter wavelength which essentially increases the total frequency produced

An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.
An element is a substance in which all of the atoms have the same atomic (proton) number. It is also defined as a substance which cannot be broken down by chemical means.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combination is
Answers
Answer:
The equivalent resistance of the combination is R/100
Explanation:
Parallel Connection of Resistances
If resistances R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]
The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.
It's known the 10 parts or resistance R/10 were connected in parallel, thus the electric resistance is:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}+...+\frac{1}{R/10}[/tex]
Note the sum consists of 10 equal terms. Operating on each term:
[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]
The sum of 10 identical fractions yields 10 times each fraction:
[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]
Solving for Re needs to take the reciprocal of both sides of the equation:
[tex]R_e=R/100[/tex]
The equivalent resistance of the combination is R/100

Given the impulse acting on an object and the impact time which equation can be used to calculate the force applied to an object
Answers
Answer is D
Ndmdjdndbdjdkskd
The impulse acting on an object and the impact time, the equation F= I / Δt can be used to calculate the force applied to an object, therefore the correct answer is D.
What is impulse?The product of the average applied force and the time for which it is exerted is known as an impulse.
the mathematical relation for impulse is
Impulse = F * Δt
where F represents the force applied and Δt represents the time for which the force is applied
Thus, the correct equation that can be used to calculate the force applied to an object is F = I /Δt and the correct option is D.

A 1 kg box is sitting on a flat horizontal surface that has a coefficient of static friction value of 0.8. What answer best states the minimum force required to move the box in the horizontal direction?
A. >-9.8N
B. >9.8N
C. >7.84N
D. >9N
Answers
The normal force felt by the box has magnitude
F[normal] = (1 kg) g = 9.8 N
so that the maximum magnitude of static friction is
F[s. friction] = 0.8 F[normal] = 7.84 N
In order to get the box to move, (C) a minimum force of 7.84 N is required.

silicon has a shiny luster,But it is brittle and conducts electricity poorly.Some metalloids change their characteristics when they react with different elements.Luster conductivity and malleability are physical properties can be observed be observed without attempting to change the identity of the substance.The term physical property is an observable characteristics of a substance. in this case the luster conductivity and malleability of metals are the properties, which can be observed by our senses.It differs from chemical properties which can only be observed when the substance change its chemical identity.
Metal are solid at room temperature with the exception of mercury which is liquid at room temperature.Luster metal have the quality of reflection light from its surface and can be polished e.g gold,silver and copper.

The electric field between two parallel plates has a magnitude of 180 N/C. The two plates are 2.5 cm apart. Recall that the magnitude of the charge on an electron is 1.602 × 10-19 C.
How much work is done to move an electron from the positive plate to the negative plate?
4.0 × 10-21 J
7.2 × 10-19 J
4.5 J
7200 J
Answers
Answer:
b
Explanation:
The amount of work done to move an electron from the positive plate to the negative plate is : 7.2 * [tex]10^{-19}[/tex] J
Step 1: Given data
magnitude of two parallel plate ( E ) = 180 N/C
Distance between plates ( d ) = 2.5 cm
magnitude of charge on electron ( e ) = [tex]1.602 * 10^{-19}[/tex] C
Step 2 : determine the work done
Work done = qV = еEd
= [tex]1.602 * 10^{-19}[/tex] * 180 * 2.5
= 720 * [tex]10^{-22}[/tex] J ≈ 7.2 * [tex]10^{-19}[/tex] J
Hence the amount of work done to move an electron from the positive plate to the negative plate = 7.2 * [tex]10^{-19}[/tex] J
