Both the plane and the horizontal surface have a coefficient of kinetic friction with the mass of 0.377. When the spring is compressed, the mass is 1.50 m from the bottom of the plane. a) What is t
Assuming that the frictional force is constant, determine how much time elapsed between the moment the bullet entered the tree and the moment it stopped.
A cannonball of mass 8.11 kg is shot from a cannon at an angle of 34.21° relative to the horizontal and with an initial speed of 40.71 m/s. As the cannonball reaches the highest point of its tra
In a cylindrical gas counter with a ventral wire radius equal to 25 micro meters (.001 in.), outer radius 25mm, and 1000 V applied between anode and cathode, what is the distance from the center of
Which of these is correct about passing an argument by call-by-value process? a) Copy of argument is made into the formal parameter of the subroutine.
Now suppose a charge +2Q is placed on the inner conductor and a charge -Q is placed on the out conductor. what is the surface charge density on each of the three surfaces in the problem?
A 3.77-kg ball of clay is thrown downward from a height of 3.47 m with a speed of 4.81 m/s onto a spring with k = 1690 N/m. The clay compresses the spring a certain maximum amount before momentaril
A 45-kg crate is placed on an inclined ramp. When the angle the ramp makes with the horizontal is increased to 30 ? , the crate begins to slide downward. What is the coefficient of static friction
A particle of mass m and energy E is inside a square tube with infinite potential barriers at x = 0, x =a, y = 0 and y = a. The tube is infinitely long in the z direction. Inside the tube, V = 0.
Calculate the entropy change of steam between states P1 = 36 bar, T1 = 250 oC, and P2 = 22 bar, T2 = 400oC by direct application of the definition of entropy. Hint: devise a path of constant-pressur
Calculate the electric field E at the center of the cylinder (since the radius is much larger than the height, the edge effects can be neglected)
He stops one-fifth of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge at the near end?
A bird watcher meanders through the woods, walking 0.519 km due east, 0.759 km due south, and 2.14 km in a direction 35.4° north of west. The time required for this trip is 2.60 hr. Determine th
A wire is bent to fit the curve y = 1 - x^2. A string is stretched from the origin to a point (x,y) on the curve. Use the method of Lagrange multiplier to find (x,y) to minimize the length of the st
For the position of the box given, determine the force in the cable and the reactions between the box and the chute. The chure is parallel to the xz plane. Neglect the size of the box and the winch.
When a capacitor has a charge of magnitude 57 µC on each plate, the potential difference across the plates is 11 V. How much energy is stored in this capacitor when the potential difference a
