A flea jumps by exerting a force of 1.27 10^-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.12 10^-6 N on the flea. Find the direction and magnitude (in m/s²) of the acceleration of the flea if its mass is 6.0 10^-7 kg. (Let us assume that F_wind points to the right. We will consider this to be the +x direction and vertical to be the +y direction.)

magnitude m/s²

direction ° (measured clockwise from the vertical)

A hydrogen electron, initially in its second excited state (n=3), jumps down to the ground state...

A hydrogen electron, initially in its second excited state (n=3), jumps down to the ground state n=1. The energy of n=1 state is -13.6 eV. A) What is the energy of the photon emitted from this jumping down process? ( I got 12.08889eV) B) Is this emitted photon energetic enough to create photoelectrons from Ni( Ni working function is 5 eV)? C) If this emitted photon (from the jump down from n=3 to n=1) is reabsorbed by a hydrogen electron...

A spring with force constant k = 175 N/m is attached to the ground. On top of the spring a 1.30 kg metal pan is attached. The combination could be used as a scale, but we are going to do something more interesting. We place a metal ball with mass 0.250 kg on the tray and then the tray is pushed down 0.150 m below its equilibrium point and released from rest (take this as t = 0). a) At...

A rope exerts an 18-N force while lowering a 20-kg crate down a plane inclined at 20∘ (the rope is parallel to the plane). A 24-N friction force opposes the motion. The crate starts at rest and moves 11 m down the plane. Part A: Determine the final speed of the crate. The system consists of the crate, the surface of the incline and Earth. Part B: Determine the change in gravitational energy. Part C: Determine the change in kinetic energy....

A fan exerts a force of 10 N on a frictionless cart of mass 250 g,...

A fan exerts a force of 10 N on a frictionless cart of mass 250 g, accelerating the cart from rest over a distance of 0.5 m. The same fan is then used to accelerate a 500 g cart from rest over the same distance. Select ALL statements below that are TRUE about this situation: A) The energy transferred to both carts is different. B) The work done by the fan in both cases is the same. C) The final...
