Answer: Electron
In atom, there are proton and neutron inside the nucleus and electron which was moving in orbit outside of the nucleus. The electron is a negatively charged, a proton is positively charged and neutron is neutral. Since there are only proton and neutron in the nucleus it's become positively charged.
Answer:
At the moment contact is made with the battery, the voltage across the resistor is equal to the batteries terminal voltage
Explanation;
Because at series connection the battery and resistor have equal voltage
Answer:
15 V
Explanation:
Electric potential is given as the product of Electric field and distance. Mathematically:
V = E * r
Where E = Electric field
r = distance = 6m
Electric field, E, is:
E = F / q
Where F = Electric force = 5N
q = Electric charge = 2C
Therefore, electric potential will be:
V = (F * r) / q
V = (5 * 6) / 2
V = 15V
The data not given here is the specific heat capacity of pyrex glass equal to 0.75(J/g °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g °C / 23 g equal to 110. 75 <span>°C </span>
Air spaces are used in insulation because air is a poor conductor.
