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 car and a truck are heading directly toward one another on a straight and narrow street. Find the distance between the two vehicles when they come to a stop.
An object with a charge of -3.1 mu C and a mass of 1.7×10-2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Find the magnitude of the electric field.
Two carts with masses of 4.5 kg and 3.9 kg move toward each other on a frictionless track with speeds of 5.6 m/s and 4.3 m/s, respec- tively. The carts stick together after colliding head-on. Find their final speed. Answer in units of m/s.
Calculate the average speed of hydrogen nuclei in a gas with a temperature of 2 107K (recall MP8.1). Now compare this answer with the speed of a galaxy moving in a circular orbit of radius 1 Mpc around a galaxy cluster of mass 1014M.
A projectile is shot from the edge of a cliff h = 285 m above ground level with an initial speed of v0 = 115 m/s. Determine the time taken by the projectile to hit point P at ground level.
The anode of an x-ray tube may reach temperatures near the melting point of tungsten, 3380 degrees C. How much more rapidly would it radiate heat there than at room temperature (22 degrees C)?
If the gas in a container absorbs 288 J of heat, has 145 J of work done on it, then does 64 J of work, what is the increase in the internal energy of the gas?
A 48.8 kg pole vaulter running at 11.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.2 m/s and disregarding air resistance, how high was the jump?
Assume that the block is not moving initially. In unit-vector notation (Fx i + Fy j), what is the force on the block from the wall?
