Answer:
the vertical component of the force is 43.30 N.
Explanation:
Given;
angle of inclination of the force, θ = 60⁰
magnitude of the force, F = 50 N
The vertical component of the force is calculated as follows;
[tex]F_y = F \times sin(\theta}\\\\F_y = 50 N \times sin(60)\\\\F_y = 50 N \times \frac{\sqrt{3} }{2} \\\\F_y = 25\sqrt{3} \ N\\\\F_y = 43.30 \ N[/tex]
Therefore, the vertical component of the force is 43.30 N.

Increasing the mass of the objects
Increasing the density of the objects
Increasing the distance between the objects
Increasing the temperature of the objects
Answers
Increasing the distance between the objects
here's the Answer :
=》Increasing the distance between the objects.
since, gravitational force is inversely proportional to the distance between the objects, so if the distance increases the force will decrease.

Explanation:
V = voltage
I = current
R = resistance
V = IR is the equation to find out the Voltage of an item so if we move around the equation so we are trying to resistance it would become R = V/I. So....
V = IR
R = V/I
R = 24/3
R = 8
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
Answers
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

Jeremy's daughter has more mass, so it takes less force to get her into the air.
Jeremy's son has more mass, so it would take more force to reach the same height as his daughter.
Jeremy's son has less mass, so it would take more force to reach the same height as his daughter.

When trying to simplify and find the equivalent resistance you should first simplify resistors in _ before simplifying those in _
Answers
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]

An 80 kg runner has 3,000 J of kinetic energy. What is her velocity in m/s?
Answers
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

The energy transferred to the water in 100 seconds was 155 000 J. specific heat capacity of water = 4200 J/kg °C
Determine the mass of water in the kettle.
Use Figure 10.
Give your answer to 2 significant figures.
Any help would be appreciated
Answers
Answer:
0.37 kg
Explanation:
I'm not a professor myself, but this is how I worked it out:
using the graph, after 100 seconds, the temperature is 100 degrees Celsius.
If we now substitute everything into the specific heat capacity equation, making the mass "m", we would come up with:
4200 = 155000/(m x 100)
If we rearrange and solve for m, we get 0.37 kg.
I'm not sure if I have done this correctly, feel free to correct me.
Hope this helps!
By using the specific heat capacity formula, the mass of water in the kettle is 0.47 kg
Give that the energy transferred to the water in 100 seconds was 155 000 J and the specific heat capacity of water = 4200 J/kg °C
From the graph;
The initial temperature of the water at time zero is 22 degree Celsius
The final temperature of the water at time 100s is 100 degree Celsius
Change in temperature (T) = 100 - 22 = 78 degree Celsius
To determine the mass of water in the kettle, use the heat energy formula below
E = mcT
Substitute all the parameters into the equation
155000 = 4200 x 78 M
Make M the subject of the formula
M = 155000/327600
M = 0.47 kg
Therefore, the mass of water in the kettle is 0.47 kg

Covalent compounds......
Answers
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.

At which angle do wires have to be to experience full force? What happens at other angles?
Answers
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
