Using thermogravimetric curve we can relate the mass changes to the stoichiometry involved. calculate the percentage weight loss for the following compounds when they are heated at uniform rate in thermogravimetric analysis.
1- Ca(OH)2
2-NH4NO3
3-CuSO4
A 1.2 kg toy car traveling at 2.0 m/s to the right collides and sticks to a 2.0 kg toy car traveling at 1.6 m/s to the left. What fraction of the total initial kinetic energy was lost in the collision
A construct force vector F = 2.0i + 4.0j N acts on an object as it means along a straight- line path. If the object is displacement is d = 2.0i + 5.0j m calculate the work done by vector F
A luge and its rider, with a total mass of 90 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 38 m/s. If a force slows them to a stop at a constant rate of 1.4 m/s2.
Suppose the horizontal velocity of the wind against a sail is 5.5 m/s parallel to its front surface and 3.3 m/s along its back surface. Calculate the approximate force on a square meter of sail in N
A 9.8 kg object oscillates at the end of a vertical spring that has a spring constant of 1.9 * 10^4 N/m. The effect of air resistance is represented by the damping coefficient b= 3.00 Ns/m.
What is the charge on the drop. A 13 kg child on a playground swing moves with a speed of 3.6 m/s when the 6.0 m long swing is at its lowest point. What is the angle that swing makes with the vertical when the child is at the highest point.
a thin, uniform bar of length D = 1.28 m and mass M = 0.67 kg pivoted at the top. find the speed of the particle before impact
A foam ball of mass 0.150 g carries a charge of -2.00 nC. The ball is placed inside a uniform electric field, What are the magnitude and direction of the electric field
A chimp jumps up from a trampoline and lands on the ground, 1.2 meters below. the total time taken was .095 secons. A. what is the initial velocity B. what is the final velocity C. what is the maximum height above the ground please show work so i ..
You power a series R-L-C circuit with a sine-wave generator operating at a frequency 1.00 kHz. What is the rms voltage supplied by the source
A skateboarder, starting from rest, rolls down a 13.1-m ramp. If the ramp is inclined at 26.5 ° with respect to the ground, what is the component of her acceleration that is parallel to the ground
Suddenly this mass is struck by another 2.00-kg object traveling along the x-axis at 3.00 m/s, and the two masses stick together.
