Answer:
b
Explanation:because endothermic contains heat so cookies need heat
as it is given that
2.2 lbs = 1 kg
here we know that Megan Progress weighs 130 lbs
so its mass in kg is given as

now to find the weight in Newton unit we can say



so 130 lbs weighs as 579 N in SI units
Density is a material property, so the second cube will have the same density as the first.
Answer:
B:The actual power dissipated by the resistor is less than P because the ammeter had some resistance.
Explanation:
Here,power has been calculated using current I and total EMF \ε . So,P=EMF*current= ε I will represent total power dissipated in resistor and ammeter.
Now, this total power P has been dissipated in both resistor and ammeter. So, power dissipated in resistor must be less than P as some power is also dissipated in ammeter because it has non-zero resistance.
So, the answer is B:The actual power dissipated by the resistor is less than P because the ammeter had some resistance.
Note that option A,C and E are ruled out as they state power dissipated by resistor is greater than or equal to P which is false.
Also,option D is ruled out as ammeter is connected in series.
