A dog pulls on a leash with a force of 15 23 is a big dog. The leash makes an angle of 36.7 degrees to the horizontal. What are the x
and y components of the force?
Answer:
[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]
Explanation:
The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N
[tex]Force = 15N[/tex]
[tex]\theta = 36.7[/tex] to the horizontal
Required
Solve for the x and y components
Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.
[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component
[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component
Calculating the y component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Sin\theta = \frac{y}{Force}[/tex] becomes
[tex]Sin(36.7) = \frac{y}{15}[/tex]
Make y the subject
[tex]y = 15 * Sin(36.7)[/tex]
[tex]y = 15 * 0.5976[/tex]
[tex]y = 8.964N[/tex]
Calculating the x component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Cos\theta = \frac{x}{Force}[/tex] becomes
[tex]Cos(36.7) = \frac{x}{15}[/tex]
Make y the subject
[tex]x = 15 * Cos(36.7)[/tex]
[tex]x = 15 * 0.8018[/tex]
[tex]x = 12.027N[/tex]
Hence, the x and y components of the force are: 8.964N and 12.027N respectively.

Answer: Well it's not sinking. It is also not flooring or floating. so my guess it must be rising up.
Explanation: When something is impacted, the pressure of the force of energy is released and lands directly on a other object. So what does Jell-O do when you shake it? It wobbles right? what happens when you put your hand in a bucket of water? It makes the water rise up. So That's why I think it is rising up.
Answer:
Rising up because the weight of the object depends on the water and mass

A stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy
Answer:
A
Explanation:
Given that a stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy. (use 9 - 10 m/s)
O at the moment of impact
2 seconds after the stone is released after the stone has fallen 40 m
when the stone is moving at 20 m/s
At the top of the hill, the P.E = mgh
P.E = 10 × 80 × m
P.E = 800m
At the moment of impact, K.E = 1/2mv^2
K.E = 1/2 × 40^2 × m
K.E = 1/2 × 1600 × m
K.E = 800m
Since both P.E and K.E are the same, we can therefore conclude that the stone's potential energy with respect to the ground is equal to its kinetic energy at the moment of impact.
The correct answer is option A.

If an airplane with a mass of 4,536 kg has gravitational potential energy of 1000 kilojoules, what is its height?
Answer:
The height is 22,472.84 m
Explanation:
Gravitational potential energy is the type of energy that is stored in the gravitational field. In other words, the gravitational potential energy as the energy that a body possesses due to the fact of being under the action of gravity, that is, the energy associated with an object subjected to force, weight, and weight is called gravitational potential energy. that is at a certain height with respect to a reference level.
The greater the weight of a body, the greater the gravitational potential energy and, considering the effect of this variable together with that of the height h at which the object is, the gravitational potential energy is:
Ep = m*g*h
In this case:
Ep= 1,000 kJ= 1,000,000 J (being 1 kJ=1,000 J)m=4.536 kgg= 9.81 [tex]\frac{m}{s^{2} }[/tex]h=?Replacing:
1,000,000 J=4.536 kg* 9.81 [tex]\frac{m}{s^{2} }[/tex] *h
Solving:
[tex]h=\frac{1,000,000 J}{4.536 kg*9.81\frac{m}{s^{2} } }[/tex]
h= 22,472.84 m
The height is 22,472.84 m

which apparatus Is used to determine the volume of a small block of unknown material
Options are;
A: measuring cylinder, metre rule
B: measuring cylinder, stopwatch
C: metre rule, balance
D: metre rule, stopwatch
Answer:
A: measuring cylinder, metre rule
Explanation:
Usually, when measuring volume of a small material, we make use of a piece of laboratory apparatus known as measuring cylinder which is also known as graduated cylinder.
Since it is a graduated cylinder, it means we will make use of metre rule.
Thus, the correct option is option A.
The apparatus which can be used to determine the volume of a small block of unknown material is: measuring cylinder; meter rule.
A measuring cylinder can be defined as a graduated cylinder that is typically designed and developed for the measurement of the volume of an irregularly shaped piece of object or a small block of unknown material.
Basically, a measuring cylinder is typically marked with horizontal lines on its side as units of measurement for volume.Similarly, a meter rule refers to an apparatus that is used for the measurement of the length of an object.
Hence, the meter rule would be used in measuring the length, width and height of the small block of unknown material, in order to determine its volume while using this formula:[tex]Volume =length\times width \times height[/tex]

Diana hangs a lead cylinder with a force of 12 N from a model bridge.
Which vector(s) accurately illustrates the reaction force of the bridge on the lead cylinder?
The action and reaction law allows us to find that the reaction force, the weight of the cylinder, is:
12 N force directed upward
Newton's third law or action and reaction law, establishes that if two bodies interact with each other the force that one applies to the other, is equal in magnitude to the force of the second on the first but in the opposite direction, that is, all forces act in pairs one in each body that interact.
Forces with these characteristics are called action and reaction.
In this case we have a hanging cylinder, with the cylinder it has mass so the weight is 12 N it acts on the table in a downward direction, let's say this is the action force.
In response to this force, the table exerts a force on the cylinder of equal magnitude but in the opposite direction, which is why it is directed upwards.
let's analyze the force diagram
When analyzing the forces shown in the diagram, the forces of equal magnitude to the weight are the first twoThe weight is directed downward, the answer must be directed upward.
In conclusion using theaction and reaction law we find that the answer for reaction force is:
12 N force directed upward

In a hydraulic lift, a 620 N force is exerted on a 0.20 m2 piston in order
to support a weight that is placed on a2.0 m2 piston. How much pressure is
exerted on the narrow piston? How much weight(force) can the wide piston lift?
Answer:
Pressure on the narrow piston = 3100 [tex]N/m^2[/tex]
The wider piston can lift the weight up-to 6200 N
Explanation:
Given that the area of the narrow piston = 0.2 [tex]m^2[/tex]
Applied force on the narrow piston, [tex]F_{in}[/tex]= 620 N
Area of the larger piston = 2.0 [tex]m^2[/tex].
As pressure = force/ area,
So. pressure exerted on the narrow piston, [tex]P= 620/0.2=3100 N/m^2[/tex]
There is liquid in between the narrow piston and the larger piston and according to Pascal's law, the pressure inside any liquid is uniformly distributed.
As the narrow piston is applying the pressure on the liquid which is equal to the external pressure applied on the narrow piston, i.e 3100 [tex]N/m^2[/tex].
So, the uniformly distributed pressure in the fluid is 3100 [tex]N/m^2[/tex].
Now, the liquids apply pressure on the larger piston,
as force = Area x pressure, so the applied on the larger piston, [tex]F_{out}[/tex], by the liquid is
[tex]F_{out} = 3100\times2=6200[/tex] N
Hence, the wider piston can lift the weight up-to 6200 N.
A rock has a mass of 3.1 kg. What is its weight on earth

A rollercoaster car has 2500 J of potential energy and 160 J of
kinetic energy at the top of the first hill.
How much energy and what kind of energy will there be at the
bottom of the first hill?
2660 J of KE
0 2660 J of Peg
2500 J of KE
160 J of PEG
Answer:
E_{k2}=2660 [J] kinetic energy.
Explanation:
The energy in the initial state i.e. when the rollercoaster is at the top is equal to the energy in the final state i.e. when it is at the bottom of the hill.
These states can be represented by means of the second equation.
[tex]E_{k1}+E_{p1}=E_{k2}\\160 + 2500 = E_{k2}\\E_{k2}=2660 [J][/tex]
Since the rollercoaster is located in the bottom of the hill where the potential energy level is zero, therefore there is only kinetic energy in the second state.
