Q. An 8.00 point mass and a 15 point mass are held in place 50 apart. A particle of mass is released from a point between the two masses 13.00 from the 8 mass along the line connecting the two fixed masses.
Find out the magnitude of the acceleration of particle.
select the quantity that has changed(velocity or speed) for a car that travels north at 88 km/h and then turns east while continuing to move at 88 km/h. define your answer.
Find out the frequency of a sound wave moving through iron at 25 degrees Celsius with a wavelength of 0.601m.
A helicopter is ascending vertically with a speed of 5.57. At a height of 124 above the Earth, package is dropped from a window. How much time does it take for the package to reach the ground?
W hat is the downward acceleration of the blue spool
A 13 g bullet traveling 217 m/s penetrates a 2 kg block of wood and emerges cleanly at 153 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
The force on a particle is directed along an x axis and given by F = 0.97(x/4.6 - 0.52) where x is in meters and F is in Newtons. Find out the work done by the force in moving the particle from x = 0 to x = 8.9 m.
An electric motor rotating a workshop grinding wheel at a rate of 93 rev/min is switched off. Assume the wheel has the constant negative angular acceleration of magnitude 2rad/s2.
Somewhere between the Earth and the moon, gravity from these two bodies on the space pod would cancel. Is this location nearer the Earth, the moon, or in the middle (having the same distance between) of the earth and the moon.
A cord of length 1.0m is fixed at both ends. Its mass per unit length is 1.2g/m and the tension is 11N. What is the frequency of fundamental oscillation
In photo like the Hubble Deep Field, we see galaxies in many different stages of their lives. In general, which galaxies are seen in the earliest (youngest) stages of their lives.
The velocity graph of a car accelerating from rest to a speed of 60 km/h over a period of 30 seconds is shown. Approximation the distance, d travelled throughout this period.
An object, mass 2.96kg, moves in a horizontal circle with a radius of 3.8m. The object has the intial velocity of 32.6 m s-1. If the kinetic coefficient of friction between the object and the surface is 0.31, then number of completed revolutions (..
