A flat circular coil with 110 turns, a radius of 3.80 × 10-2 m, and a resistance of 0.340 ? is exposed to an external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field is changing at a rate of ?B/?t = 0.789 T/s. Find the induced current in the coil.
A light ray enters a glass slab at point A at an angle of 57.6° with respect to the surface normal and then undergoes total internal reflection at point B. What minimum value for the index of refraction of the glass can be inferred from this?
List out five to ten specific things that project managers can do to help manage stakeholders. Provide some examples of successful and unsuccessful relationships with project stakeholders.
A 65.0 kg human sprinter can accelerate from rest to 10 m/s in 2.90 s. all through the same interval, a 33 kg greyhound can accelerate from rest to 20 m/s. calculate (a) change in kinetic energy and (b) average power output for each.
An object at rest explodes into three pieces of equal masses. One moves east at 23 m/s, while the second piece moves northwest at 14 m/s. Estimate the velocity of the third piece? Suppose each piece has a mass of 2 kg.
If the trough is being filled with water at the rate of 0.3 m3/min explain how fast is the water level rising when the water is 10 cm deep?
You are driving to grocery store at 15 m/s .You is 140 m from an intersection when the traffic light turns red. Suppose that your reaction time is 0.70 s. and that your car brakes with constant acceleration. How far are you from the intersection whil..
A uniform plank of length 4.9m and weight 228N rests horizontally on two supports, with 1.10m of the plank hanging over the right support. To what distance x can a person who weighs 449N walk on overhanging part of the plank before it just begins ..
A cardinal (Richmondena cardinalis) of mass 4.10×10^-2 kg and a baseball of mass 0.144 kg have the similar kinetic energy. What is the ratio of the cardinal's magnitude pc of momentum to the magnitude pb of baseball's momentum.
An Olympic runner is at the starting gate and hears the starting gun, Using only acceleration, ai, and time, tr, write an expression for the runner's final speed, vr, when he crosses the finish line
A racing car travels with a constant tangential speed of 75 m/s around a circular track with a radius 625 m. Find (a) the magnitude of the car's total acceleration and (b) the direction of its total acceleration relative to the radial direction.
A ranger in a national park is driving at 52 km/h when a deer jumps onto the road 86 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -2.9 m/s2.
A Sphere on a Horizontal Surface starts from Rest. If the Force is applied facing to the Right at the Top furthest Point of the Sphere from the Horizontal Surface, the Sphere will start experiencing Roll and Slip at the same time. In which directi..
