The Figure(Figure 1) Shows The Angular-velocity-versus-time Graph For A Particle Moving In A Circle,

Answers

Answer 1

Answer:

As position is the product of velocity and time, the area under the velocity-time curve will be the position.

Between 2 and 4 s, the area increases linearly to 20(4) = 80

Between 4 and 6 s, the additional area is 0(2) = 0

Between 6 and 8 s the area increases linearly by -10(2) = -20

which is a decrease.

The Figure(Figure 1) Shows The Angular-velocity-versus-time Graph For A Particle Moving In A Circle,
Answer 2

In the angular-position vs time graph;  The angular position is derived from the area under the velocity vs time graph

Attached below is the angular position vs time graph

Given that : Angular position = Angular Velocity * time

As Time increases from 0 to 4 secs the area increases from 0 to 80 rad

As Time increases from 4 to 6 secs the area remains constant i.e. 0 rad

As Time increases from 6 to 8 secs the area under the graph decreases 80 to 60 rad

Hence we can conclude that the Angular position of the graph is derived from the area under the velocity vs time graph.

Two masses m1 13.6 kg and m2 22.9 kg are connected by a rope that hangs over the pulley. The pulley has form of solid cylinder of radius 0.6 m and mass 10.6 kg. Initially m1 is on the ground and m2 rests 8.0 m above the ground. At some moment system is released. Find velocity of m2 just before it hits the ground. Neglect friction in the pulley.

Answers

The conservation of energy allows finding the result of the velocity of the body 2 when it reaches the ground is:

          v = 6.32 m / s

Given parameters

Body mass 1   m₁ = 13.6 kg body mass 2   m₂ = 22.9 kg height   y = 8.0 m

To find

speed.

The conservation of energy is one of the most important principles of physics, it establishes that if there is no friction force, the mechanical energy is conserved at all points, where the mechanical energy is the sum of the kinetic energy plus the different potential energies.

Let's write the energy at two points before we drop the system.

     Em₀ = U₁ + U₂

Where potential energy is

    U = m g y

They indicate that body 1 is on the ground and body 2 is at a height .

      y₂ = 8 m

      Em₀ = m₂ g y₂

Let's write the energy of the system for when body 2 is reaching the ground

       [tex]Em_f[/tex] = K₂ + K₁ + U₂ + U₁

At this moment body 2 is reaching the ground, its height is zero and the height of body 1 is y₁ = 8 m. Since the two bodies are joined by the rope, they must have the same speed..

      [tex]Em_f[/tex] = ½ (m₁ + m₂) v² + m₁ g y₁

As there is no friction, the energy is conserved.

      Em₀ = Em_f

      m₂ g y₂ = ½ (m₁ + m₂) v² + m₁ g y₁

The rope is inextensible, the heights are equal.

       y₁ = y₂ = y = 8.0 m

     

      v² = [tex]\frac{m2-m1}{m2+m1} \ 2g y[/tex]  

Let's calculate.

       [tex]v^2 =\frac{22.9-13.6}{ 22.9+13.6} \ 2 \ 9.8 \ 8 \\ v = \sqrt{39.95}[/tex]

       

      v = 6.32 m / s

In conclusion using the conservation of energy we can find the result of the velocity when the body 2 reaches the ground is:

          v = 6.32 m / s

A car is being driven along a road at 25m/s when the driver suddenly notices that there is a fallen tree blocking the road 65m ahead. The driver immediately applies the brakes giving the car a constant velocity of 5m/s2. How far in front of the tree does the car come to rest?

Answers

Hi there!

We can use the following equation to solve for displacement:

vf² = vi² + 2ad, where:

vf = final velocity

vi = initial velocity

a = acceleration

d = displacement

Since the car will come to rest, vf = 0, so:

0 = vi² + 2ad

Plug in the given values:

0 = 25² + 2(-5)d (Breaking is a negative acceleration in this instance)

Solve:

0 = 25² - 10d

10d = 625

d = 62.5m

Subtract from the total distance from the car to the tree:

65 - 62.5 = 2.5m

Un rió de 89 m de ancho fluye agua con una velocidad de 4.0 m/s hacia el este . Si el bote tiene una velocidad de 8 m/s con relación al agua.
Que distancia rio abajo se desplaza el bote al cruzar el rió.

Answers

6

Explanation:

yhhhunkmombfdcgjjyvunkkbdsfgbjjj

La distancia que el bote se desplaza rio abajo es 44.5 metros.

¿Que distancia rio abajo se desplaza el bote?

Debemos recordar que la velocidad en cada eje es independiente de la velocidad en el otro eje. Tambien recordar que:

distancia = velocidad*tiempo.

Esto quiere decir que si el bote se mueve a 8m/s de un extremo al otro del rio, esta velocidad en esta dirección se va a mantener.

Entonces el tiempo que tarda en viajar 89 metros (el ancho del rio) a una velocidad de 8m/s es:

T = (89 m)/(8m/s) = 11.125 segundos.

Ahora notamos que durante esos 11.125 segundos el bote tambien se mueve siguiendo el flujo del rio, a una velocidad de 4.0 m/s, entonces la distancia que el bote se desplaza rio abajo es:

D = 11.125s*4.0m/s = 44.5 metros

For Part A, Sebastian decided to use the copper cylinder. How would the magnitude of his q and ∆H compare if he were to redo Part A but this time using an aluminum cylinder of equal mass? Assume that the initial temperatures of the metals (Tm) and the initial temperatures of the water (Ti) were the same. Specific heat of copper: 0.385 J/g*K Specific heat of aluminum: 0.900 J/g*K Group of answer choices The magnitudes of his q and ∆H for the copper trial would be higher than the aluminum trial. The magnitudes of his q and ∆H for both trials would be the same The magnitudes of his q and ∆H for the copper trial would be lower than the aluminum trial.

Answers

The magnitudes of his q and ∆H for the copper trial would be lower than the aluminum trial.

The given parameters;

initial temperature of metals, =  [tex]T_m[/tex]initial temperature of water, = [tex]T_i[/tex] specific heat capacity of copper, [tex]C_p[/tex] = 0.385 J/g.Kspecific heat capacity of aluminum, [tex]C_A[/tex] = 0.9 J/g.Kboth metals have equal mass = m

The quantity of heat transferred by each metal is calculated as follows;

Q = mcΔt

For copper metal, the quantity of heat transferred is calculated as;

[tex]Q_p = (m_wc_w + m_pc_p)(T_m - T_i)\\\\Q_p = (T_m - T_i)(m_wc_w ) + (T_m - T_i)(m_pc_p)\\\\Q_p = (T_m - T_i)(m_wc_w ) + 0.385m_p(T_m - T_i)\\\\m_p = m\\\\Q_p = (T_m - T_i)(m_wc_w ) + 0.385m(T_m - T_i)\\\\let \ (T_m - T_i)(m_wc_w ) = Q_i, \ \ \ and \ let \ (T_m- T_i) = \Delta t\\\\Q_p = Q_i + 0.385m\Delta t[/tex]

The change in heat energy for copper metal;

[tex]\Delta H = Q_p - Q_i\\\\\Delta H = (Q_i + 0.385m \Delta t) - Q_i\\\\\Delta H = 0.385 m \Delta t[/tex]

For aluminum metal, the quantity of heat transferred is calculated as;

[tex]Q_A = (m_wc_w + m_Ac_A)(T_m - T_i)\\\\Q_A = (T_m -T_i)(m_wc_w) + (T_m -T_i) (m_Ac_A)\\\\let \ (T_m -T_i)(m_wc_w) = Q_i, \ and \ let (T_m - T_i) = \Delta t\\\\Q_A = Q_i \ + \ m_Ac_A\Delta t\\\\m_A = m\\\\Q_A = Q_i \ + \ 0.9m\Delta t[/tex]

The change in heat energy for aluminum metal ;

[tex]\Delta H = Q_A - Q_i\\\\\Delta H = (Q_i + 0.9m\Delta t) - Q_i\\\\\Delta H = 0.9m\Delta t[/tex]

Thus, we can conclude that the magnitudes of his q and ∆H for the copper trial would be lower than the aluminum trial.

What is defined as the isolation and reduction of variables in an experiment in order to understand the impact of a specific variable or variables on the outcome of the study?

Answers

aisnhsjdjxbxbxhxbxjx

Isolation and reduction of variables in an experiment is a way to reduce administrative efforts, costs and delusions occur.

What is an experiment?

An experiment is a technique used to prove or disprove a theory, or to test the efficacy or probability of something that has never been done before.

Experiments reveal cause-and-effect relationships by illustrating what happens when a specific component is changed.

Experiments have a wide range of goals and scales, but they always rely on a repeatable technique and rational interpretation of the outcomes. Natural experimental research is also available.

If you can plan a control group, you will be much better off. It increases the expense of the experiment by a factor of two and may cause delusions.

Furthermore, it doubles the administrative effort. However, it provides the most reliable and straightforward method for calculating significance,

By comparison, taking into consideration the deviations of each of the two groups of data that arise.

In many circumstances, a control group is required for analysis when you wish to look at certain lag periods or increases in addition to the final result.

Hence isolation and reduction of variables in an experiment are much more important to reduce.

A simple pendulum is made of a small blob of mass m=7.000 kg attached to the end of an inextensible wire. The angular amplitude of oscillation is θ=5.730°. Consider that the gravitational acceleration is g=9.807 m/[tex]s^{2}[/tex]. What is the magnitude of the tension in the wire when the blob is directly below its point of support?

Answers

Answer:

The tension must be equal to the weight of the bob plus the centripetal force that is provided at eth end of the motion.

h = L (1 - cos theta)  where h is the height to which the bob is raised

cos 5.730 = .995

h = .005 L

Also    1/2 m v^2 = m g h    speed of the bob at the bottom

v^2 = 2 g h = .01 g L    where 2 h = .01 L

v^2 / L = .01 g

m v^2 / L = .010 g m = .07 g    since m = 7

Total tension = m g (1 + .07) = 1.07 m g

T = 9.807 * 1.07 * 7 = 73.45 kg m / s^2
