Answer:
Law 2:
Pushing a baby on a swing is easier than pushing an adult on the same swing. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.
Law 2:
When thrown with the same force, a soccer ball accelerates more than a bowling ball.
Law 1:
A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.
Law 3:
A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.
Law 1:
A book rests on top of a shelf and does not move until a student accidentally knocks it off.
Explanation:
Newton's laws of motion:
Law 1: Law of inertia
Law 2: Law of force (F = mass x acceleration)
Law 3: Law of Action & Reaction
The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.
What is meant by inertia ?Inertia is defined as the tendency of an object to continue its state of rest or motion.
Here,
Considering the situations given,
1. Pushing a baby on a swing is easier than pushing an adult on the same swing.
This is because, the mass of the baby is lesser than that of the adult. So, according to Newton's force equation,
Force, F = ma
Therefore to push a body with more mass, more force should be applied.
Another situation that follows this law from the given situations is:
When thrown with the same force, a soccer ball accelerates more than a bowling ball.
2. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.
This is due to the inertia of the water in the glass. This can be explained by law of inertia.
Another situation that follows this law from the given situations is:
A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.
A book rests on top of a shelf and does not move until a student accidentally knocks it off.
3. A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.
This is according to Newton's third law of motion. The law of action and reaction.
Hence,
The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

When trying to simplify and find the equivalent resistance you should first simplify resistors in _ before simplifying those in _
The equivalent resistance for the parallel connected resistance will be
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]
What is resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω)
Now if two resistances are connected parallel then the voltage on the resistances will be different and the same current will flow from both resistances.
[tex]V_{eq}=V_1+V_2[/tex]
[tex]I_{eq}R_{eq}=I_1R_1+I_2R_2[/tex]
Since [tex]I_{eq}=I_1=I_2[/tex]
[tex]R_{eq}=R_1+R_2[/tex]
Hence the equivalent resistance for the parallel connected resistance will be
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

At which angle do wires have to be to experience full force? What happens at other angles?
Answer:
The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°
Explanation:
The direction of the force acting on a conductor through which a charge flows is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field
Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force

A spiral staircase winds up to the top of a tower in an old castle. To measure the height of the tower, a rope is attached to the top of the tower and hung down the center of the staircase. However, nothing is available with which to measure the length of the rope. Therefore, at the bottom of the rope a small object is attached so as to form a simple pendulum that just clears the floor. The period of the pendulum is measured to be 8.5 s. What is the height of the tower
Answer:
L = 17.94 m
Explanation:
The angular velocity of a simple pendulum is
w = [tex]\sqrt{ \frac{g}{L} }[/tex]
the angular velocity is related to the period
w = 2π / T
we substitute
[tex]\frac{4\pi ^2 }{T^2} = \frac{g}{L}[/tex]
L = [tex]\frac{g T^2}{4 \pi ^2}[/tex]
let's calculate
L = 9.8 8.5² / 4π²
L = 17.94 m

Covalent compounds......
Covalent compounds are characterized by bonding that involves sharing electrons.
Covalent compounds have the ability to share electrons as they mostly have 4 valence electrons.
What are covalent compounds?
Covalent compounds are defined as type of compounds which are formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent compounds have bonding which involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

An 80 kg runner has 3,000 J of kinetic energy. What is her velocity in m/s?
Answer: 8.6m/s
Explanation:From KE=1/2mv^2
In order to make v the subject of the formula we divide both sides by 1/2m. Thus V^2 will be left alone on the RHS. But we are looking for v and not v^2. Thus we find the square root of KE1/2m
Meaning V= sqrt[3000÷1/2 of 80]
=sqrt[3000÷40]
=sqrt(75)
=8.6m/s
