Answer:
new energy of the capacitor is half that of initial energy
Explanation:
As we know that the energy stored in the capacitor is given as
here we know that capacitance of parallel plate capacitor is given as
V = voltage of battery
so now we have capacitor remains connected to the same battery and the separation between the plates is doubled
so we have
so now the energy stored between the plates is
so new energy of the capacitor is half
The answer to Willem's experiment are as follows;
A) The two other measurements Willem will require to calculate the specific heat capacity of copper are;
- The mass of the copper block
- The change in temperature of the copper block after heat is supplied.
B) The block must be well insulated to ensure no heat energy is lost to the surrounding by conduction, convection and radiation and hence, all heat supplied is used to effect a change in temperature in the copper block as intended.
C) If the block is poorly insulated, energy is lost and hence, the result would be too high because more energy would be consumed in the process.

Answer:
I think its 9.0397 Ohms
Explanation:
take the reciprocal of all the resistances: 1/15, 1/65, 1/35
then add them: = 151/1365
then reciprocal the answer: =1365/151
And chuck it on a calculator: =9.04 Ohms
I think this is right but I'm not entirely sure. Tell me if I'm right by the way!
<span>Possible explanation one would be people are outdoors more due to the use of the snow blower and are thus more susceptible to falling as a result if the increased time spent near or on the ice. Possible explanation two is the snow that's removed from their sidewalk can no longer provide a traction surface between the people clearing the snow and the ice that lies beneath the snow. And possible explanation number three would be that the snow blowing machine, being a new piece of equipment to people, requires a level of agility to operate and inexperienced operators lack the agility to use the piece of equipment.</span>
