The diagram shows object N placed one on top of object M. M has a mass of 4 kg and N has a mass of 2 kg. Assume that all the contact surfaces are frictionless, what is the acceleration of N when M is pulled by a force of 20 N? A. 0 m/s² B. 4 m/s² C. 3.3 m/s² D. 10 m/s²
A cylinder is rolling along the ground at 2m/s . It comes to a hill and starts going up.Assuming no losses to friction, how high does it get before it stops
A vernier caliper of least count 0.1mm is used to measure the length of tube. The length of tube is found to be 5cm long. How should this measurement be recorded in a table of results?
In addition to being insanely adorable, the Klipspringer is known to jump 3.6 meters straight up in the air (that is several times their body height). What is the initial upward velocity required to make this happen?
Assuming we have a 1 cm long empty solenoid with a 1 mA current flowing through it, how many loops do we need to have in the solenoid to generate a 1 T magnetic field inside the solenoid? Give your answers as integers rounded up N = What if we had an iron core inside the solenoid with relative permeability of 64,000 ? How many loops would we need in this case? N =
A boat crosses a river at 6.65 mph north through a current going 9.87 mph east. What is the resultant velocity of the boat?
Please help, it's a question on Elasticity!A wire can support a load W without breaking. It is cut in to two equal parts. The maximum load that each part can support is (1) W/4 (2)W/2 (3) W (4) 2W (5) 4W
Children slide down a frictionless water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at point A and lands in the water at point B, a horizontal distance L = 2.42 m from the base of the slide, determine the height h (in m) of the water slide.
Water drips from rest from a leaf that is 12.0 meters above the ground. Neglecting air resistance, how long does it take the water drop to hit the ground? What is the speed of each water drop when it hits the ground?
Kathy walks west at 1.4 m/s for 6 minutes. She then goes east at 2.7 m/s for 4 minutes. What was her total overall displacement in meters? Part b Kathy walks west at 1.4 m/s for 6 minutes. She then goes east at 2.7 m/s for 4 minutes. What was her total overall displacement in kilometers? Part C Kathy walks west at 1.4 m/s for 6 kinutes. She then goes east at 2.7 m/s for 4 minutes. What was her average velocity?
Aside from density, what other information from the table of planetary data can help someone decide if a planet is terrestrial, jovian, or dwarf?
Two protons (charge q= 1.602·10-19 C) move at the same speed v= 1.4 ·106 m/s in opposite directions parallel to the x-axis. At the instant when they are at the same x-position, the proton moving in the negative direction is at distance r= 0.7 mm in the positive y-direction with respect to the one moving in the positive direction. What is the magnitude of the magnetic field at the point of the proton moving in the negative direction? B= What is the magnetic force direction experienced by the proton moving in the negative direction? FB=
two vehicle are moving in same direction the first one has velocity of 24m/s another has 18m/s find their relative velocity & also their relative velocity when they are moving in opposite direction
what is the terminal velocity for a 3.78kg bowling ball falling through air? Use 0.45 for the drag coefficient of the bowling ball and 1.22kg/m^3 for the density of air. A standard bowling ball has a diameter of 21.6 cm
