find the potential gradient between two parallel plate conductor of separation 0.03 when potential difference of 540 supplied to them hence determine the force in an electron which club between the plates
A large pot contains 5.00×10−3 m3 of water at 23.0 °C. How much thermal energy must be removed from the water to freeze it into ice at 0.00 °C (in MJ)? [Latent heat of fusion for water: 333.4 kJ kg−1 , specific heat of water: 4190 J kg−1 K−1 , density of water: 1000 kg m−3 .]
The specific weight of an unknown liquid is 12 400 N/me. What mass of the liquid is contained in a volume of 500 cm3? Use: the minimum value of gravity on the earth
Andrea has a particularly old bike, and she has not lubricated the chain or gears. This causes friction inside the gears as she rides. She begins coasting on flat ground at a speed of 10 m/s, and after a few seconds is only going 8 m/s. How much energy has been converted to heat?
Y=0.3sin(0.5x-50t). what is the maximum displacement of the particles from the equilibrium portion
A piano wire 0.5m longlong has a total mass of 0.01kg and is stretched with a tension ofof 800N. calculate the tension of the wire when it sounds it's fundamental note.
A hiker travels 4,5 km in a direction 12 degrees south of west and then 7,2 km in a direction 23 degrees west of south.
Determine the hiker’s overall displacement.
Draw each of the hiker’s individual displacement vectors on the same set of Cartesian axes, so that their initial points coincide at
Cody’s car accelerates from 0m/s to 45 m/s northward in 15 seconds. What is
the acceleration of the car?
What is the speed of sound in a helium gas at a pressure of 15000pa
Four point charges are positioned as such: A(0,1), B(2,1), C(0,0), D(2,0). Charge A = -3 microcoulombs, Charge B = 3 microcoulombs, C = 2 microcoulombs, and D = -2 microcoulombs. What is the net electric field experienced at the origin.
