(a) A straight conducting wire is placed perpendicularly to the earth
magnetic field at a location. The earth magnetic field at the location has a
magnitude of 0.450 G. Determine the current that must flow in the wire for a
9.50 cm length of the wire to experience a magnetic force of 1.50 N due to the
earth magnetic field.
[1 T = 104 G]
(b) A wire of length 1.0 m carries a current of 1.0 A. The wire is formed into a
circular coil and the circular coil has one turn only. Determine the magnitude of
the maximum torque which is developed on the coil if it is placed in magnetic
field of 2.0 T.
Consider the following premises:
1.A-->(B-->A) is a theorem of proportional calculus for all statements A and B.
2.suppose then that the following are the temporary axioms.
a)w
b)y
c)y-->z
Using the logical rules of inference, modus ponens and hypothetical syllogism, show that x-->z is diducible from the given premises.
You probably are fond of games. This quiz though is not that complicated. You are simply going to work with a point on a screen, and a circle on a screen as well. And let's consider them as the characters in the game. We are going to call both of these characters as Movable objects. Objects are said to be Movable if they can be moved around the screen. The following simple movements are allowed:
public void moveLeft(); // moves the x to the left by 1 unit
public void moveRight(); // moves the x to the right by 1 unit
public void moveUp(); // moves the y 1 unit upward
public void moveDown(); // moves the y 1 unit downward
public void display(); // prints all the info about
How many seconds would it take for a 4.50kw motor to raise a 175.kg boiler to a height of 15.0m?
(a) the displacement x, in m, from the equilibrium position of a particle moving with simple harmonic motion, is given by, x= 0.05 sin 6t, where t is the time, in s, measured from an instant when x= 0. (1) state the amplitude of the oscillations. (2) calculate the time period of the oscillations and the maximum acceleration of the particle.
(b) A mass hanging from a spring-suspended vertically is displaced a small amount and released. By considering the force on the mass at the instant when the mass is released, show that the motion is simple harmonic and derive an expression for the time period. Assume that the spring obeys Hooke's law.
A wire with a mass of 64 g and 1 m long floats horizontally in magnetic field. If
B = 1.6x10^-2 T is at the direction perpendicular to the wire, calculate the value of current in the wire with the aid of a diagram.
