Answer: B.
but the resistance is lower in the parallel circuit.
Explanation:
A circuit with parallel connections has a lower total resistance than the resistors connected in series. This is consistent with conservation of charge. The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source.
Answer:
Explanation:
work done on an ideal gas, PV = - nRT
since the pressure is constant PΔV = - nRT
where n, number of moles = 0.240 mol, R, gas constant = 8.314 J/mol K
work done = - nR ( T₂ - T₁) = 0.24 mol × 8.314 ( 270 - 15) = -508.8 J
Answer:
Th steps is as shown in the attachment
Explanation:
from the diagram, its indicates that twelve identical charges are distributed evenly on the circumference of the circle. assuming one of gthe charge is shifted to the centre of he circle alomng the x axis, as such the charge is unbalanced and there is need ot balanced all the identical charges for the net force to be equal to zero.
The mathematical interpretation is as shown in the attachment.
Answer:
, assuming that there's no heat exchange between the washing machine and the environment.
Explanation:
Let denote the mass of water and the specific heat capacity of water. The energy required to raise the temperature of that much water by would be:
.
Washing at would require a temperature change of .
Washing at would require a temperature change of .
In both situations, while .
Calculate the energy required in either situation:
Washing at :
.
Washing at :
.
.
take the volume that is submerged. That's the volume of water displaced.
but the volume of submerged is different in those two
so buoyancy force is different in those two
weights are the same
probably. since the densities* are different.
In question it says wights are the same and diffferent volumes
so it seems that the one with more density should have a lower buyonacy force
but you said that when an object floats the buoyancy force equals weight,so since both objects have the same weight,then buoynacy force should be equal in those two
The more dense object will float with a greater percentage of its volume immersed, not less.
2) If they have the same MASS, the more dense one will have less VOLUME
