Q1. Pluto is 29.66 AU away from the Sun at perihelion and 49.31 AU at aphelion. What is Pluto's orbital eccentricity?
Q2. An airplane is flying with the velocity of 82.0 at an angle of 22.0 above the horizontal. When the plane is a distance 111 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land?
You can ignore air resistance.
Points A and B have electric potentials of 320 and 160, respectively. When an electron released from rest at point A arrives at point C, its kinetic energy is.
Differentiate between the following three types of plain carbon steels.
The sun falls on a concave mirror and forms an image 4.5 cm from the mirror. If an object 22 mm high is placed 12.7 cm from the mirror, where will its image be produced.
A 66 N m torque acts on a wheel with a moment of inertia 175 kg m2. If the wheel starts from rest, how long will it take the wheel to make one revolution? The system is released from rest and accelerates under the weight of m2.
Create horizontal component of the pendulum
Both systems start from rest, and the direction of the force moves with the system and always points along the 4.00 m rod. What is the angular velocity of each system after 5.28 s.
What approximations or simplifying assumptions must you make in the calculations? (Note: Some of these choices are false because they are wrong physics!)
Some skin divers go as deep as 50 m. What is the gage pressure at this depth in fresh water, and what is the ratio of absolute pressure at this depth to normal atmospheric pressure.
A particle travels counter clockwise around the origin at constant speed in the circular path that has a diameter of 2.50 m, going around twice per second. Point Q is on the path halfway between points P and R that lie on the x axis and the y axis..
Find out the magnitude of the electric field at a point P on the y-axis 0.529 m from the origin. The value of the Coulomb constant is 8.99 × 109 N • m2/C2.
A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53, and is supposed to be caught by Joe Bob, whose hands are 6.10 above and 8.02 horizontally from her launch point. You can ignor..
The coefficient of kinetic friction between a 20 Kg box and the floor is 0.40. How much work does a pulling force do on the box in pulling it 8.0 m at the constant speed? The pulling force is directed 390 above the horizontal.
