Aneutron is an electrically neutral subatomic particle with a mass just slightly greater than that of a proton. a free neutron is radioactive and decays after a few minutes into other subatomic particles. in one experiment, a neutron at rest was observed to decay into a proton (mass 1.67×10^−27kg) and an electron (mass 9.11×10−31kg). the proton and electron were shot out back-to-back. the proton speed was measured to be 1.0×105 m/s and the electron speed was 3.2×107 m/s . no other decay products were detected. a. did momentum appear to be conserved in the decay of this neutron? b. if a neutrino was emitted in the above neutron decay, in which direction did it travel? c. explain your reasoning. d. how much momentum did this neutrino carry away with it?

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
