Answer:The peak resistor voltage in an RC high-pass filter can be calculated using the following formula:
V_R = V_in - V_C
where V_R is the peak resistor voltage, V_in is the peak voltage of the AC source, and V_C is the peak voltage across the capacitor.
Substituting the given values, we get:
V_R = 9.00 V - 5.6 V = 3.4 V
Therefore, the peak resistor voltage is 3.4 V. Note that the unit of voltage is volts (V).
Explanation:
an object is on a horizontal surface. three forces act horizontally on the object: 3 N to the left, 12 N to the right, 1 N to the left. At the same time, another three forces act vertically on the object: 4 N upwards, 10 N downwards , 2 N upwards.
determine the resultant horizontal and vertical forces acting on the object.
Answer:
Resultant horizontal force : 16 N
Resultant vertical force : 4 N
Explanation: Force acting on left : 3N
Force acting on left : 1 N
Forces acting on left : 3N + 1N = 4N
Force acting on right : 12 N
Resultant horizontal force : 12 N - 4 N = 16 N
Force acting upwards : 4 N
Force acting upwards : 2 N
Forces acting upwards : 4 N + 2 N = 6 N
Force acting downwards : 10 N
Resultant vertical force : 10 N - 6N = 4 N
An amusement park ride consists of a rotating circular platform 7.4 m in diameter from which 10 kg seats are suspended at the end of 1.81 m massless chains. When the system rotates, the chains make an angle of 26.6 degree with the vertical. The acceleration of gravity is 9.8 m/s
a). what is the speed of each seat? answer in units of m/s
b). if a child of mass 49.1 kg sits in a seat, what is the tension in the chain ( for the same angle)? answer in units of N
a) The speed of each seat in an amusement park ride of a rotating circular platform is calculated to be 5.57 m/s.
b) The tension in the chain if a child of mass 49.1 kg sits in a seat is calculated to be 650.79 N.
a) By drawing a free body diagram, we represent the two types of forces on the seat. They are represented by the equation, sum of forces in the y direction,
∑F = ma
T cos θ − mg = 0
T = mg / cos θ
Sum of forces in the centripetal direction,
∑F = ma
T sin θ = m v² / r
(mg / cos θ) sin θ = m v² / r
m g tan θ = m v² / r
g tan θ = v² / r
v = √(gr tan θ)
First, let us find the radius of the path,
r = 7.4 / 2 + 1.81 sin 26.6°
r = 3.7 + 1.81× 0.45 = 6.33 m
v = √(9.8 m/s² × 6.33 m × tan 26.6°)
v = √(9.8 × 6.33 × 0.5) = 5.57 m/s
b) T = mg / cos θ
T = (10 kg + 49.1 kg) (9.8 m/s²) / cos 26.6° = 579.2/0.89
T = 650.79 N

Analyze the IR spectra for both t-butanol and 1-butanol.
If the reactions were successful what do you expect to see in the IR of the product compared to the starting material?
If the reactions were successful then we can see the reactions involved O-H groups of the alcohols then the O-H stretching will not be observed in the product.
Analysis of IR spectrum of 1-butanol:
There are sp3 C-H stretching and CH2 bending modes at 2900 and 1500 cm-1 and there is a C-O stretching mode near 1050 cm-1. There is a very large peak around 3400 cm-1. O-H peaks are usually very broad due to H -bonding.The rounded shape O-H stretching modes occurs because of hydrogen bonding between different hydroxy groups.
Because protons are shared to varying extent with neighboring oxygens, the covalent O-H bonds in alcohol all vibrate at slightly different frequencies and show up at slightly different positions in the IR spectrum.
Instead of seeing one sharp peak, the entire range is observed as a whole lot of them merged into one broad peak. Since C-H bonds don't hydrogen bond very well, hence this phenomenon is not observed for C-H stretching.
Analysis of IR spectrum of tertiary-butyl alcohol:
There are sp3 C-H stretching and alkane C-H bending modes at 2900 and 1500 cm-1 and there is a strong C-O stretching mode near 1200 cm-1 indicative of tertiary C-O, there is a broad peak around 3400 cm-1 indicative of H bonding.

9. 5 people each pull with 200 N each on an object. What is the net force on the object?
Answer:
1000 N
Explanation:
The net force is sum of all forces when considering in a one-dimensional motion. Since each people pull the object 200 N then that means 5 people together would pull 5 × 200 N = 1000 N.
Therefore, the net force is 1000 N
A chain of metal links with total mass m = 5 kg is coiled up in a tight ball on a low-friction table. You pull on a link at one end of the chain with a constant force F = 64 N. Eventually the chain straightens out to its full length L = 0.8 m, and you keep pulling until you have pulled your end of the chain a total distance d = 3.2 m (diagram is not to scale). m ------- 1000000000000000 T> (a) Consider the point particle system: What is the speed of the chain at this instant? V = m/s (b) Consider the extended system: What is the change in energy of the chain? AE = joules (c) In straightening out, the links of the chain bang against each other, and their temperature rises. Assume that the process is so fast that there is insufficient time for significant thermal transfer of energy from the chain to the table, and ignore the small amount of energy radiated away as sound produced in the collisions among the links. Calculate the increase in thermal energy of the chain. AEthermal =
The speed of the chain at this instant is 8.47 m/s. The change in energy of the chain is 204.8J. The increase in thermal energy of the chain is 25.6J.
Acceleration(a) of Centre of mass = F/m = 64/5 = 12.8 m/s2
a) v2 = u2 + 2as,....(1)
It defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. It is the rate of change of displacement.v is final velocity of centre of mass,
u is the initial velocity of centre of mass,
s is the displacement of centre of mass
s = d - L/2 = 3.2 - 0.4 = 2.8m
using equation 1,
V = [tex]=\sqrt{2as} =\sqrt{2*12.8*2.8}=8.47 m/s.[/tex]
Therefore, the speed of the chain at this instant is 8.47 m/s.
2. Change in energy = Total Work Done = Force*Displacement of point on which force is applied = 64*3.2 = 204.8J
Therefore, the change in energy of the chain is 204.8J
3. Change in Thermal Energy = Change in Energy - Change in Kinetic Energy = 204.8 - 0.5*m*v2
Change in Thermal Energy = 204.8 - 0.5*5*8.47*8.47 = 25.6J

The speed of the combined train cars after they couple cannot be determined from the information given. The velocity of an object is determined by its speed in a given direction, but it is not specified in which direction the train cars are moving.
Additionally, the concept of momentum must be considered to calculate the final velocity of the combined train cars.
The principle of conservation of momentum states that the total momentum of a closed system (in this case the train cars) remains constant unless acted upon by an external force. Therefore, we would need to know the initial momentum of each train car and the external forces acting on the system in order to calculate the final velocity of the combined train cars.

can someone please explain centripetal and centrifugal forces, whats the difference and how would they effect friction if at all?
Centripetal force is the portion of a force exerted on an object in curvilinear motion that is directed at the axis of rotation or the centre of curvature. A fictitious force that moves in a circle and is directed away from the centre is called centrifugal force.
What is meant by Centripetal force?Any force that induces a shift in velocity direction toward the centre of a circular motion is referred to as a centripetal force.Centripetal force is caused by the part of the force that is perpendicular to the velocity.
