Q. An ion accelerated through 180.00 V has its potential energy decreased by potential energy of 5.76 10-17 J. Calculate the (magnitude of the) charge on the ion.
Q. A uniform electric field of magnitude 445 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 3.10 cm.
What is the work done by the field on the electron?
How would you describe why we have different atmospheric pressure on different level (height) of earth's atmosphere in molecular level (molecular behaviour and what causes such behaviour).
A toy train with 1.2kg mass is moving at a stright line platform with the velocity 12m/s. It collides another toy train of 0.9kg mass with velocity of 7m/s. If e = 0.8, what is the velocity of each train after the collision.
Besides the gravitational force, a 3.25-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (4.10 - 3.30) m, where the direction of is the upward vertical direction. find out ..
Write down the equation for a transverse sinusoidal wave with an amplitude of 2.5 cm and an angular frequency of 2.90 rad/s that is moving along the positive x-direction with a wave speed that is 5 times as fast as the maximum speed of a point on ..
100 g ball of clay is thrown horizontally with a speed of 13m/s toward a 900g block resting on a frictionless surface. It hits the block and sticks. The clay exerts a constant force on the block during the 7 ms it takes the clay to come to rest re..
What is an index of refraction of the liquid
Cube of ice is taken from the freezer at -8.5°C and placed in a 75-gram aluminum calorimeter filled with 300.0 grams of water at room temperature of 20.0°C. The final situation is observed to be all water at 17°C. What was the mass of the ice cub..
Considered frequency and draw the nodal maps
What is the capacitance of this capacitor. Estimate the terminal speed of a wooden sphere (density 0.810 g/cm3) falling through air, if its radius is 8.00 cm and its drag coefficient is 0.5.
what is the magnitude of the charge on each sphere. A car crashes into a wall at 45 m/s and is brought to rest in 0.1 s. compute the average force exerted on a 80 kg test dummy by the seat belt.
An airplane with a mass of 2.6*10^6 kg. has the air flow past the lower surface of the wings at 100 m/s. If the wings have a surface area of 1200 m2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the ai..
Ignoring friction and air resistance, find the maximum height H to which she rises above the end of the track.
