Compare and contrast natural versus anthropogenic climate changes. Include specific examples of each. Take a position as to whether or not global warming is taking place. Provide three (3) lines of evidence to support your position.
A soccer player kicks a rock horizontally off a 35.0 m high cliff into a pool of water. If the player hears the sound of the splash 2.84 s later, what was the initial speed given to the rock? Assume the speed of sound in air to be 343 m/s.
A motorist is traveling at 18 m/s when he sees a deer in the road 38 m ahead. (a) If the maximum negative acceleration of the vehicle is -4.5 m⁄s^2 , what is the maximum reaction time ?t of the motorist that will allow him to avoid hitting t
After the collision, the club head travels (in the same direction) at 41 m/s. Find the speed of the golf ball just after impact.
They are fixed in place on the same straight line and adjacent charges are equally separated by a distance d. Consider the net electrostatic force acting on each charge. Calculate the ratio of the largest to the smallest net force.
The critical angle of refraction for calcite is 68.4° when it forms a boundary with water. Use this information to determine the speed of light in calcite.
A 2.00-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 4.60sin(2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 20.0 N/m.
An airplane is heading due south at a speed of 485 km/h. A wind begins blowing from the southwest at a speed of 100 km/h (average). What is the velocity (magnitude and direction) of the plane relative to the ground?
A football coach sits on a sled while two of his players build their strength by dragging the sled across the field with ropes. The friction force on the sled is 1200 N and the angle between the two ropes is 19.0^circ. How hard must each player pu
