Suppose that an ocean current has a velocity of 2.6 m/s that makes an angle of 32 degrees from the positive x-direction with respect to the earth. A boat is sailing in the ocean current with a velocity of 4.3 m/s in the positive x-direction with respect to the earth. What is the x-component of the velocity of the ocean current with respect to the boat?
A car starts from rest and then accelerates uniformly to a linear speed of 16 m/s in 42 s. If the tires have a radius of 27 cm, what are the following.
A hairless cat's body temperature is 7.5 degrees C higher than a human's. Part A: Find the hairless cat's temperature in degrees C. Part B: Find the hairless cat's temperature in degrees F. Express your answers using one decimal place and include the..
A wire made of aluminum is 882 m long and has a cross-sectional area of 36.6 10-7 m2. It is observed that 6.6 C pass through the wire in 79.2 s. Determine the power loss of the wire
An 8.00-mH inductor and a 2.00ohm resistor are wired in series to an ideal battery. A switch in the circuit is closed at time 0, at which time the current is 0. determine the time constant for the circuit
How can I make sure that this is first order? I was also wondering if my equation is correct? I have also written my equation on the graph, is that correct? What is the appropriate equation? I have to identify the specific rate constant (k) for th..

A charge q is located at the tip of a hollow cone (such as an ice cream cone without the ice cream) with surface charge density σ . The slant height of the cone is L, and the half-angle at the vertex is θ . What can you say about the force on the ..
For the description of motion in two dimensions one may use Cartesian coordinates (x(t), y(t)), or plane polar coordinates (r(t), γ(t)), where x(t)=r(t)cos(γ(t)) and y(t)= r(t)sin(γ(t)). Rewrite the kinetic energy T= 1/2 m(x'^2+y'^2) in plane polar c..
