How To Use Wiki In The Classroom
7) A solid sphere and a solid cylinder, both uniform and of the same mass and radius, roll without slipping at the same forward speed. It is correct to say that the total kinetic energy of the solid sphere is. A) more than the total kinetic energy of the. More and more classrooms are now learning, creating, reading, and testing online. In order to keep up with our technologically demanding lifestyles, the traditional classroom is making way for such innovative tools as wiki. Not only is this an inexpensive way to manage your classroom, it’s also a fun way to engage students in content across the curriculum.

I wind a string around a co ee can of radius R = 0:05 m. (That’s 5 cm.) Friction prevents the string from slipping. I apply a tension T = 20 N to the free end of the string. The free end of the string is tangent to the co ee can, so that the radial direction is perpendicular to the force direction. What is the magnitude of the. A solid sphere of mass m and radius r rolls without slipping along the track shown in Figure P10. 0 m/s in the +x-direction and 2. A solid sphere (radius R) rolls without slipping in a cylindrical trough (radius 5 R) as shown in Figure P15. (2) ration of rotational and Kinetic energy . 12 m is at rest at the top of a ramp inclined 15°. (3/4mgh.

The pulley shown above has a mass of 1.00 kg and radius R = 30.0 cm, and can be treated as a uniform solid disk that can rotate about its center. The block (which has a mass of m = 500 g) hanging from the string wrapped around the pulley is then released from rest. Use g = 10 m/s2.

The answer is not 2.68 and it also was not 3.3.

Radius of the disc r = 5 cm = 0.05m . ... As the light inextensible string is wound around the disc several times it makes the disc rotate without slipping over it. ... Four round objects namely a ring, a disc, a hollow sphere and a solid sphere with same radius R start to roll down an incline at the same time. Find out which object will reach.

A solid cylinder of radius 10.0 cm rolls down an incline with slipping. The angle of the incline is ... A bowling ball rolls up a ramp 0.5 m high without slipping to storage. It has an initial velocity of its center of mass of 3.0 m/s. (a) What is its velocity at the top of the ramp?.

1. A disk of radius 5 cm has density 10 g/cm 2 at its center, density 0 at its edge, and its density is a linear function of the distance from the center. Find the mass of the disk. my answer: 157.08 g. D = 10 − 2 x. Double integration of D from y = 0 to y = 2 π and x = 0 to x = 5. calculus integration multivariable-calculus.

Here, M = total mass and R = radius of the cylinder. Derivation Of Moment Of Inertia Of Solid Cylinder. We will take a solid cylinder with mass M, radius R and length L. We will calculate its moment of inertia about the central axis. Here we have to consider a few things: The solid cylinder has to be cut or split into infinitesimally thin rings. 10.43 A 15-kg mass and a 10-kg mass are suspended by a pulley that has a radius of 10 cm and a mass of 3.0 kg (Fig P10.32). The cord has a negligible mass and causes the pulley to rotate without slipping. The pulley rotates without friction. The masses start from rest 3.0 m apart.

A thin hoop of mass M and radius r is placed on a horizontal plane. At the initial instant, the hoop is at rest. A small washer of mass m with zero initial velocity slides from the upper point of the hoop along a smooth groove in the inner surface of the hoop. Determine the velocity u of the centre of the hoop at the moment when the washer is at a certain point A of the hoop, whose.

  1. Set Clear Expectations
    Before setting wiki guidelines and sharing them with your students, consult your school’s policies on social media. Provide students with written guidelines that must be adhered to. Let students know that if they publish inappropriate content, there will be consequences. Asking students to sign a contract is also an option.
  2. Start Small
    Take baby steps. Everyone will benefit from gradually increasing wiki use in the classroom. By starting small, teacher’s can stay on top of monitoring classroom wiki, thus remaining in control.
  3. Ask for Help
    Although wiki is fairly easy to use, there are times when you’ll run into stumbling blocks. Ask for help when you don’t understand something. You’d be surprised at much your students and colleagues might know about wiki.
  4. Read other Wikis
    As a class and individually, explore other classroom wikis. This will give you ideas and inspirations for your own wiki pages.
  5. Let Wiki Work for You
    Wiki is more than just a learning tool for students; it’s a communication tool for teachers. Use wiki to keep parents informed and post assignments and other class related content. Your wiki page is easily edited and updated so there’s no more need for a last minute trip to the copy machine.
  6. School-wide Wikis
    Use wikis to showcase field trips, class events and school-wide events, such as the prom or last week’s football game.
  7. Pinterest
    This site has a wealth of information on wiki for the classroom. Simply type in a search term such as "wiki tips for the classroom".  If you don’t already have a Pinterest account, learn more about it through deep creek fishing boat rentals.
  8. Collaborate
    Do lots and lots of group work. Create assignments that require students to work together, continuously communicating as part of team as they would in the real world.  For example, a media class can work in teams to create an advertisement for a product of their choice that involves print and/or video.  For a science class, have students work together as a research team investigating the sudden drop in the local wolf population.

  1. Historical Figures
    Instead of just another boring academic paper on an historical figure, make research and documentation fun by creating wiki fan pages. Students can add and edit text, post photos and famous quotes, as well as links to the references they used.
  2. Student as Editor
    Turn grammar into a challenging and competitive game. Have students use wiki to edit text with grammatical errors. Teachers can put students into groups and those with the most edits wins.  Individual edits can also be counted.
  3. Join the Debate Team
    Using a written set of guidelines, teachers post topics that students can argue by using wiki online forums. Teachers will monitor the discussions/debates while students learn online debate etiquette.
  4. Create a Collaborative Story
    Start with one sentence pulled from a hat, “The girl looked beyond the dusty field and saw a team of horses approaching, their riders hands tied behind their backs.” From here, students add and edit text to create a story. Set a minimum amount of words each student must submit. Chances are, you’ll actually have to set a maximum amount of words.
  5. Poetry Class
    For English class, the teacher can post a poem online and have the students discuss its meaning.  Students can also post their own poems for peer review.
  6. Book and Film Reviews
    Students can use wiki to write assigned book and film reviews. Other students can add to as well as comment and discuss the reviews on a monitored forum.
  7. Word Problems
    For math class, teachers can post word problems on wiki. Students work individually or in groups to solve the problems.
  8. Wiki Worlds
    For history and social studies, students can create pages for historical events such as famous battles or specific periods in history, creating entire worlds based on historical facts.
  9. Geography
    Wiki pages can be used to study geography by giving states or countries their own wiki page. Have students include useful and unique information about each geographical area.
  10. Fact Checking
    The reason why wikis is often blacklisted as a reputable source is because not everyone who contributes to a wiki page is an expert. Keep your students on their toes by assigning them to fact check each other’s work.
  11. Riddles
    Encourage teamwork by posting riddles and having groups of students solve them through online collaboration. The students will use a forum to discuss what the possible answer is.
  12. Group Assessments and Tests
    As an alternative way to administer assessments, consider using wiki group assessments.  Students work together, helping one another to achieve success.

Answer (1 of 8): In hollow cylinder all the particles are located at the same distance R from the axis of rotation while in a solid cylinder particles are present between also .. There are particles which lie very close to the axis. Since moment of inertia is propotional to r².. Thus a solid cyli.
