His is an artist's model of the solar system. The scale bar in the drawing represents AU s. One AU is the distance rom the Sun to the Earth, which is about 93 million miles or 150 million kilometers. Is this an accurate scale model? Explain A) No. If Earth is 1 AU away from the Sun, Neptune should be about 30 AU'S away. It is not B) Yes, it is an accurate scale model showing the relative distances of each planet from the Sun. C Yes the drawing is to scale. The artist shows how the diameters compare as well as the distances from the Sun in AU's. Neither the distances from the Sun or the size of the planets are drawn to scale. Both are too small according to actual distances and diameters,

Part bperform the experiment by following these directions:step 1using the sticky notes, label the thermometers t1 and t2. make sure that both thermometers are at room temperature (around 21c). then, in the table, record their temperatures and the time of this initial measurement.step 2place 1 tablespoon of baking soda in a small glass or jar. carefully add one-fourth cup of white vinegar. when the mixture starts to bubble or fizz, place the first thermometer (t1) near (not in!) the glass. then cover the glass and the thermometer with one of the upside-down soda bottles. if the thermometer cannot stand vertically on its own or it is too large to lay horizontally within the soda bottle, it can lean against an inner side of the soda bottle.step 3immediately place the other soda bottle upside down over the second thermometer (t2). place each bottle approximately 4 to 5 inches apart under the lamp or other heat source. turn on the lamp to expose each bottle to heat. the lamp or heat source represents the radiant energy that earth receives from the sun. the gases inside the bottles represent two different atmospheric compositions. determine how the amount of radiant energy absorbed by each atmosphere changes by tracking the temperature in the table.(left) a thermometer and beaker be(left) a thermometer and beaker beneath an inverted pop bottle; (right) alone thermometer beneath an inverted pop bottle; a single sunlamp shines on both bottlesstep 4in the table, record the temperature of each thermometer every 2 minutes for the first 10 minutes. then record the temperature every 5 minutes for the next 20 minutes (30 minutes total). if the temperature exceeds your thermometer rating, move the lamp farther away and repeat this step.

At t=0 a grinding wheel has an angular velocity of 21. 0 rad/s. It has a constant angular acceleration of 26. 0 rad/s2 until a circuit breaker trips at time t = 2. 10 s. From then on, it turns through an angle 438 rad as it coasts to a stop at constant angular acceleration. Through what total angle did the wheel turn between t=0 and the time it stopped?
