1. Most PE, because PE is directly proportional to distance (height)
Height: 100 meters
Speed: 0 mph

2. Most KE, because KE is directly proportional to speed
Height: 10 meters
Speed: 40 mph

3. Most TE, average KE
Height: 10 meters
Speed: 40 mph

4. The skater gains thermal energy as she goes down the slope, because the speed of the skater increases, so it increases the total kinetic energy of the particles, and makes them vibrate faster, resulting in a higher temperature.

What life process requires specialized cells in multicellular organisms
worty [1.4K]
The most probable answer for this question would be that almost every life process requires specialized cells in multicellular organisms. To simply put it, cells of multicellular organisms are specialized in a way that they are all grouped into their respective tissues and these tissues are all grouped into their respective organs and these organs are all grouped together into their respective systems and these systems make up the multicellular organisms. These systems have their own functions in maintaining and sustaining the life that the organisms has. The organs have their own functions as well, thus specialized cells are mostly needed in respiration, digestion, circulation, movement, excretion, reproduction, immunity, coordination, and synthesis.

A fish takes the bait and pulls on the line with a force of 2.3 N. The fishing reel, which rotates without friction, is a unifor
natulia [17]

Explanation:

The given data is as follows.

     Pulling force on the reel is F = T = 2.3 N

     Mass of cylinder (m) = 0.82 kg

    Radius of cylinder (r) = 0.045 m

Formula for torque pulling force on the cylinder is as follows.

           \tau = Fr

                     = I \times \alpha

Moment of inertia of the cylinder (I) is as follows.

            I = \frac{mr^{2}}{2}

  \alpha = angular acceleration of the cylinder

Hence,

                    Fr = (\frac{mr^{2}}{2}) \alpha

or,   \alpha = \frac{2F}{mr}

                   = \frac{2 \times 2.3 N}{0.82 kg \times 0.045 m}

                   = 124.66 rad/s^{2}

Amount of line pulled is h and it is in a times of 0.2 sec.

Now, linear acceleration is calculated as follows.

             a = r \alpha

                = 0.045 m \times 124.66 rad/s^{2}

                 = 5.61 m/s^{2}

Now, relation between h and acceleration as follows.

             h = v_{o}t + \frac{1}{2}at^{2}

here,   v_{o} = 0

Hence, calculate the value of h as follows.

             h = v_{o}t + \frac{1}{2}at^{2}

                = 0 + \frac{1}{2} \times 5.61 m/s^{2} \times (0.2s)^{2}

                = 0.1121 m

Thus, we can conclude that acceleration of the fishing reel is 5.61 m/s^{2} and it will pull 5.61 m/s^{2} line from the reel in 0.20 s.
