I have a motorola radius p1225 and I had it on the charger all night. When I woke up this morning I took it off the base charger and turned it on but nothing happened. I put it back on the base charger and turned it on and it worked. Please help me figure out what to do!
safely at 23 m/s without...? At what angle should a curve of radius 115 m be banked, so cars can travel safely at 23 m/s without relying on friction?
Ive been trying this one i thought it was tan ? = v^2 /rg but it isnt can some one plz help

Assume that a driver (car modeled as a point mass) is negotiating a circular turn with a radius of 160 ft. The car and driver have a combined mass of 3800 lb and the coefficient of friction between the car and the road is u1=0.85. What is the max constant speed the car can travel and remain on...
by 10^2 m.? (a) What is the centripetal acceleration of the car?
(b) What is the centripetal force?
(c) What is the minimum coefficient of static friction between the tires and the road that will allow the car to round the curve safely?
My husband is looking to get a job in Odenton, MD and we want to know where the best places to live around that area are. We are hoping for a nice community no longer than 45 minutes away from Odenton. School systems are very important.
How does the periodic trend of atomic radius relate to the addition of electrons? (Select all that apply.)
1.) increased nuclear charge across a period pulls the electrons closer, making the atoms smaller 2.) increased nuclear charge across a period increases the attraction for additional...

...interested in the electric field? Consider a charged ring of radius 47.9 cm and total charge 12 nC.
We are interested in the electric field a perpendicular distance z away from the center of the ring.
In centimeters, at what distance from the center of the ring does the electric field...
...box in the back of the truck is ....? You're driving your pickup truck around a curve with a radius of 24 . A box in the back of the truck is pressed up against the wall of the truck.
How fast must you drive so that the force of the wall on the box equals the weight of the box?
