Answer:

I believe the answer is B.

Explanation:

Newton's First Law of Gravity states, "The greater the weight (or mass) of an object, the more inertia it has. Heavy objects are harder to move than light ones because they have more inertia. "

Answer:

toaster -- 15 A, 8 Ω
fry pan -- 10.83 A, 11.08 Ω
lamp -- 0.83 A, 144 Ω
fuse will blow

Explanation:

P = VI

I = P/V = P/120

R = V/I = V/(P/V) = V^2/P = 14400/P

Toaster: I = 1800/120 = 15 . . . amps

R = 14400/1800 = 8 . . . ohms

Fry pan: I = 1300/120 = 10.833 . . . amps

R = 14400/1300 = 11.08 . . . ohms

Lamp: I = 100/120 = 0.833 . . . amps

R = 14400/100 = 144 . . . ohms

The total current exceeds 20 A, so will blow the fuse.

May explode with such intensity that they become part of other objects

vekshin1

Massive stars may explode with such intensity that they become part of other objects, such as neutron stars, pulsars, and black holes.
These massive stars are at least 8 times as massive as the Sun and when they explode, a supernova is created.
