Three charged particles are placed at the corners of an equilateral triangle of side 1.2
m. The charges are +4 μC, -8 μC, and -6 μC. Calculate the magnitude and direction of
the net force on each due to the other two.
1.0 mol of an ideal gas starts at 1.0 atm and 77F and does 1.0 kJ of work during an adiabatic expansion. Calculate the final volume of the gas. Express your answer in litres. In your calculation, fully show the conversion of units. Marks will be given for the necessary conversion factors and every number must have a unit in this problem!
The velocity of a particle undergoing simple harmonic motion is described by,
𝑣(𝑡) = 2.25m/s cos(0.555 rad/s∙ 𝑡 + 0.450 rad) What is the particle’s maximum acceleration?
A 6.00 kg aluminum metal is suspended in a rope and partially immersed in water (𝜌𝑤𝑎𝑡𝑒𝑟 = 1000 kg/m3). If the tension in the rope is 4.55 N, what volume of aluminum was immersed?
Based on a study, the average typing speed of women is normally distributed. Karen verified the results by conducting a similar study and found out that the standard error of the sample mean is 9 words per minute using a sample with a variance of 1 215. Determine the variance of the sampling distribution
A disk is turning with an angular acceleration of 10 m/s^2. What is the tangential
acceleration at 0.50 m from the center of the disk?
A block of mass 30.0 [kg] slides down from the top of the incline. The coefficient of kinetic friction between the block and the incline is 𝜇𝑘 = 0.350. What is the total work done on the block as it reaches the bottom of the incline?
Based on a study, the average typing speed of women is normally distributed. Karen verified the results by conducting a similar study and found out that the standard error of the sample mean is 9 words per minute using a sample with a variance of 1 215. Determine the sample size she used
