An adventurous archaeologist crosses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope. The rope will break if the tension in it exceeds 3.00×104 N. Our hero’s mass is 85.0 kg. Part A: If the angle θ is 13.0 ∘, find the tension in the rope (answer in form T= ? N. Part B: What is the smallest value the angle θ can have if the rope is not to break?

What is the difference between a shift in the demand curve and movement along the demand curve? Choose a product to use as an example and describe something specific that might cause its demand to shift. Also explain something specific that might cause movement to another point on the same demand curve.

Two brothers, Liam and Noel, play in a rock and roll band. The brothers each have 3 sons. Liam and Noel want to predict the mean drum roll speed (in hits per ten seconds) at age 5 years that would be expected for a new son. To do this, they'll use estimators based on the six children's drum roll speeds, all measured at age 5. Due to a rare genetic variant that Liam has (and that Noel does not have),...

There are two properties that affect the conduction speed of an action potential along an axon
There are two properties that affect the conduction speed of an action potential along an axon: the axon's diameter and whether or not the axon is myelinated. Rank the axons from slowest to fastest conduction speed. If two axons have the same conduction speed, place one on top of the other.

You are going to model households consisting of two adults—a man and a woman—and some kids. (While families are increasingly diverse, we are just going to focus on these households.) The adults split their time however they like between home production and the formal labour market (i.e., working for pay). Let’s assume that households care only about efficiency. (This is a really bad assumption as it means we are ignoring a lot of really important factors like the role of...

Consider the apparatus shown below in which a conducting bar can be moved along two rails connected to a lightbulb. The whole system is immersed in a magnetic field of 0.480 T perpendicularly into the page. The vertical distance between the horizontal rails is 0.800 m. The resistance of the lightbulb is 41.2 Ω, assumed to beconstant. The bar and rails have negligible resistance. The bar is moved toward the right by a constant force of magnitude 0.600 N.(a) What...

Two charges Q1( +2.00 µC) and Q2( +2.00 µC) are fixed symmetrically along the x-axis at x = ± 3.00 cm. How much work must be done to assemble these charges if they are initially infinitely far apart? For this configuration, calculate the electrical potential difference between the origin and the point P, which is located on the y-axis 4.00 cm above the origin. Now a third charge Q3( -2.00 µC) is fixed at point P. What is the electrostatic...

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 19 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 29 cm. What is the wavelength of the sound? Express your answer using two significant figures. If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum? Express your answer using two significant...
