Consider Rutherford’sexperiment. Would the estimated size of the nucleus be greater, smaller, or the same if he has used a more energetic source ofalpha particles – that is, a radioactive source in which the alpha particles are emitted withgreater energy? Explain
A pair of slits, separated by 0.160 mm, is illuminated by light having a wavelength of ? = 566 nm. An interference pattern is observed on a screen 150 cm from the slits. Consider a point on the screen located at y = 1.90 cm from the central maxim..
a 0.135-g spider hangs from the middle of the first thread of its future web. the thread makes an angle of 5.29deg with
An electron that is moving through a uniform magnetic field has a velocity v = (30 km/s)i + 18 km/s)j when it experiences a force F = (-4.000×10-15 N)i + (6.667×10-15 N)j due to the magnetic field. If Bx = 0, calculate the magnitude of the magnetic f..
The two stars in a binary star system have masses 2.2×1030 and 6.5×1030 . They are separated by 2.1×1012 .What is the system's rotation period, in years? What is the speed of the lightest star? What is the speed of the heaviest star?
How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
One cylinder in the diesel engine of a truck has an initial volume of 600cm^3. air is admitted into the cylinder at 30 degrees C and a pressure of 1.0 atm. the piston rod then does 400J of work to rapidly compress the air. what are its final temperat..
A woman of mass 60 kg runs at a speed of 5 m/s towards a carousel and jumps onto it at the very edge. what is the angular velocity of the carousel
q. an electron is projected with an initial speed u0 1.60 x 106 ms into the uniform field between the parallel plates.
While the repair shop works on your voltmeter, they loan you an unusual replacement: Rather than measuring the potential difference across a resistor, it measures the amount of charge that flowed, and the change in electric potential energy of tha..
Compare the distance he wanted to cover in the real world with the "theoretical" distance that could be covered if there was no air resistance - If the engine was close to 100% efficient how much petrol would be used to overcome air resistance duri..
A 667 kg car stopped at an intersection is rear-ended by a 1600 kg truck moving with a speed of 13.5 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of both vehicles after t..
In a volcanic eruption, a 2.40 × 103 kg boulder is thrown vertically upward into the air. Where will the other fragment land
