A girl stands on the deck of the boat and tosses a rock into a lake. The rock is thrown from a height of 2.50 m above the water surface with a velocity of 4.35 m/s at an angle of 60.0° above the horizontal. As the rock strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the rock enters the...

A Norman window is constructed by adjoining a semicircle to the top of an ordinary rectangular window. (The diameter of the semicircle is equal to the width of the rectangle.) Find the dimensions of a Norman window if the perimeter of the window is 20 fot so that the maximum amount of light is admitted, Enter the exact answers Enclose numerators and denominators in parentheses. For example, (a - b)/(1+r). Length (in feet) Width (in feet): Hint Penalty Hint 0.0...

Use the formal in this picture
A rectangular coil of 60 turns, dimensions 0.100 m by 0.200 m, and total resistance 10.0 Ω rotates with angular speed 30.0 rad/s about the y axis in a region where a 1.00-T magnetic field is directed along the x axis. The time t= 0 is chosen to be at an instant when the plane of the coil is perpendicular to the direction of B. Calculate (a) the maximum induced emf in the coil,...

Aman in a boat is 2 miles from the nearest point on the shore. He needs to get to a point 3 miles down the shore. It he can row at 4 miles per hour and run at 16 miles per hour, how far down the shore from where he starts out should he land in order to minimize the time it takes to reach his final destination? Enter the exact answer To enter Vā, type sqrt(a) He should land...

A rectangular loop has dimensions 0.505 m by 0.260 m. The loop
is hinged along the x-axis and lies in the xy-plane (see the figure
below). A uniform magnetic field of 1.45 T is directed at an angle
of 40.0° with respect to the positive y-axis and lies parallel
everywhere to the yz-plane. The loop carries a current of 0.855 A
in the direction shown. (Ignore gravitation.)

PLEASE ANSWER a,b,c
Heat Conduction Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the...
