find out the speed of the test charge. How many electrons should be removed from A and put onto B to make the electrostatic force that acts on each object an attractive force whose magnitude is 23.6 N.
A convex lens with f1= 20.3cm is mounted 39.5cm to the left of a concave lens. When an object is placed 29.4cm to the left of the convex lens, What is the focal length f2 of the concave lens
What is the wavelength of radio waves. An electron in a TV is accelerated toward the screen across a potential difference of 54.2kV. How much kinetic energy does the electron gain while accelerating.
The flowers of the bunchberry plant open with astonishing force and speed, causing the pollen grains to be ejected out of the flower in a mere 0.30 ms at an acceleration of 2.5×104 m/s2. Evaluate with what speed are pollen grains ejected from a b..
After the first spring compresses a distance of 32.1 cm, the second spring acts with the first to increase the force as additional compression occurs. The car comes to rest 47.0 cm after first contacting the two-spring system. Find the car's initi..
