A moving neutrino created a magnetic field.
A neutron that was speeding up emitted an EM wave.
A negative ion and a proton will exert no electrostatic force on each other.

An optic with a positive focal length created a real image.
In milk, loud sounds travel slower than soft sounds.
Explanation / Answer
a. A perfectly functioning hydraulic had a pressure of 31 Pa in the fluid near the small piston and a pressure of 33 Pa in the fluid near the big piston---pressure would be same but force would be different because areas are different A substance underwent melting during which its temperature remained constant at 155 °C.-----heat is entering the system so there must be temp change Last Monday, the Sun heated the Moon via convection------Convection is the transfer of energy through the movement of a fluid (liquids, gasses). Think of air conditioning in the house. Space is a vacuum so this is no good. b. A moving neutrino created a magnetic field----neutrino is neutral A neutron that was speeding up emitted an EM wave.---neutrons have no charge so cant create EM field A negative ion and a proton will exert no electrostatic force on each other-they both have charge so they must exert an electrostatic force on each other
