d=vt 235=47v v=5 ok so u basically have the horizontal component here. if u put subscripts, it is dx = vx*ttot therefor vx = 5m/s ok next, you know at in projectile motion, at max height velocity = 0m/s right? so vf = vi + at. t = 1/2 the total time because tup = tdown for projectile motion...

i have another question A proton moving at 1.2 × 106 m/s through a magnetic field of 4.3 T experiences a magnetic force of magnitude 4.9 × 10−13 N. The charge of proton is 1.60218 × 10−19 C and the mass of proton is 1.67262 × 10−27 kg. What is the angle between the proton’s velocity and...

Homework Statement A segment of wire carries a current of 20 A along the x-axis from x = −6 m to x = 0 and then along the z axis from z = 0 to z = 7.2 m. In this region of space, the magnetic field is equal to 51 mT in the positive z direction. What is the magnitude of the force on this...

hey can u play explain to me how u got part a?

hey uhh can u tell me how u found the answer to part b?

Fluid problems - " pipe " like questions Homework Statement A fireman climbs a 8 m high ladder carrying a 5 in diameter hose that has a 1.4 in diameter nozzle. The pump has an absolute pressure of 4 atm. What is the water velocity from the nozzle? Assume that water is incompressible, its...

forget it.

Homework Statement The horizontal constricted pipe illustrated in lee (vl3765) – UTHW#34-Dluid Dynamics1 – hamaguchi – (32001) 3 the figure (a Venturi tube), can be used to measure flow velocities in an incompressible fluid. The ratio for the cross section areas of the tube is A2/A1 =...

A frog in a hemispherical pod finds that he just floats without sinking in a fluid with a density of 1.27 g/cm3. If the pod has a radius of 5.4 cm and negli- gible mass, what is the mass of the frog? Answer in units of kg. Alright so for this one i converted the density to kg/m3...

wowww its a simple D = m/v formula -_-'' thnx!

but the formula is Fb = p(fluid)gv(submerged) w/o the volume idk how else to solve it.

hmm so how exactly do i find the displaced fluid? there's no dimensions for me to find the volumn of the object to find the displaced fluid

The apparent weight " loss " of the object immersed in the fluid = the weight of the liquid displaced. so in this case, the Fb would be weight of object? and the reading on hanging scale would be Fg - Fb?

Homework Statement A beaker of mass 1.4 kg containing 2.3 kg of water rests on a scale. A 2.8 kg block of a metallic alloy of density 4700 kg/m3 is sus- pended from a spring scale and is submerged in the water of density 1000 kg/m3 as shown in the figure. (a) What does the hanging scale...

ohhh thnx
