A rectangular coil of wire with an area of 0.218 m2 is situated in a constant magnetic field whose magnitude is 0.450 T. Suppose the normal to the surface of the coil is parallel to the direction of the magnetic field (this means the magnetic field is also normal, or perpendicular, to the surface of the coil). What is the flux through the surface?
If the area of the coil is reduced to 0.150 m2 while keeping the orientation of the coil the same, what is the new flux through the surface?
Go back to a coil with an area of 0.218 m2, but instead rotate the coil such that the normal to the surface of the coil is perpendicular to the direction of the magnetic field (this means the magnetic field is parallel to the surface of the coil). What is the flux through the surface?
A baseball outfielder throws a 0.150 kg baseball at a speed of 45.0 m/s and an initial angle of 28.0°. Illustrate what is the kinetic energy of the baseball at the highest point of its trajectory?
Find out the tension in the strap, given that the suitcase moves with constant speed and that the coefficient of kinetic friction between the suitcase and the floor is 0.40.

Explain how does that compare with the heat needed to reaise the temp of the same mass of water through the same temp difference?
Two uniform, solid disks are rotating freely about the same axis. Then they are linked together without the aid of any external influences. Before being connected.
A rock is thrown vertically upward from ground level at time t = 0. At t = 1.9 s it passes the top of a tall tower, What is the height of the tower
The density of water is 1000kg/m^3 or 8.33lbm/gallon, the mass flow rate is 494838.83 kg/s and goes through a turbine generator that has 0.80 efficiency
Uniform rate of acceleration
A 2.0 kg mass (mA) and a 5.50 kg mass (mB) are connected to a lightweight cord that passes over a frictionless pulley. The pulley only changes the direction of the force exerted by the rope.
A baseball player runs 27.4meters from batter's box to first base,overruns first base by 3.0 meters,and then returns to first base. Compared to the total distance traveled by the player,magnitude of the players total displacement from the batters ..
find the magnitude of the initial acceleration. At what height above the surface of the earth does the balloon have a speed of 7.30 m/s.
An air column in a glass tube is open at one end and closed at the other by a movable piston. The air in the tube is warmed above room temperature, and a 356 Hz tuning fork is held at the open end. Resonance is heard when the piston is at a distan..
