The nucleus of 8Be, which consists of 4 neutrons and 4 protons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 neutrons and 2 protons).
(a) Obtain the force between the two alpha particles when they are 3.20 x 10-15 meter apart?
N
(b) Find the magnitude of the acceleration of the alpha particles due to this force? Note that the mass of an alpha particle is 4.0026 u.
m/s2
A car with 60 cm diameter tires is traveling at a constant speed of 100 km/hr. What is the angular velocity of the tires in rad/s
Let's say that you have a mass of 45.0 kg, and that you run up a staircase as fast as you can, taking a time of 2.40 s to you raise yourself through a height of 3.00 meters. What is your power output during this process
A bat and ball approach one another each with the same speed of 1.50 m/s, collide. Determine the speed of the ball after the collision
A 1,200-N crate rests on the floor. How much work is needed to move it at constant speed 4.8 m along the floor against a friction force of 240 N? How much work is needed to move it at constant speed the same distance vertically?
Two objects move by initial velocity -8.00 m/s, final velocity 16.0 m/s, and constant accelerations. (a) The first object has displacement 20.0 m. Discover its acceleration. (b) The second object travels a total distance of 22.0 m. Discover its accel..
Suppose that a billiard ball approaches a rail at a speed of 15 m/s and an angle od 60 degrees but rebounds at a speed of 10 m/s and an angle of 50 degrees. What is the change in momentum now
A sample of aluminium has a density of 2.700×103 kg/m3. Compute the volume of 0.500 kg of aluminium (in SI units) And If this amount were shaped into a cube, what would be the length of one edge of that cube (in meters)?
A solid concrete block weighs 150. N and is resting on the ground. Its dimensions are 0.400 m 0.200 m 0.100 m. A number of identical blocks are then stacked on top of this one.
Consider point P on the viewing screen of a double-slit experiment. This point is 75% of the way from the center of the third bright fringe to the center of the fourth bright fringe. If the wavelength of the light is 600 nm, what is the extra distanc..
Compute the horizontal distance traveled by the shot if it leaves the athlete's hand at a height of 2.10 m above the ground.
It will be shown later that the scale height, H, is proportional totemperature, T. For an average temperature of 255 K, the scaleheight is 7.5 km assuming an isothermal atmosphere
