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
<u>Toaster</u>: I = 1800/120 = 15 . . . amps
R = 14400/1800 = 8 . . . ohms
<u>Fry pan</u>: I = 1300/120 = 10.833 . . . amps
R = 14400/1300 = 11.08 . . . ohms
<u>Lamp</u>: I = 100/120 = 0.833 . . . amps
R = 14400/100 = 144 . . . ohms
The total current exceeds 20 A, so will blow the fuse.
E = Energy m = Mass c = Speed of light.
Answer:
The velocity of the proton is 
Explanation:
The momentum of a particle is defined as the product of its mass by its velocity and we can calculate it using the following formula:
p=m*v Equation (1)
Where:
p: Is the momentum in kg*m/s
m: Is mass of the particle in kg
v: Is the velocity of the particle in m/s
Data known:
m= 1,6726 × 10^–27 kg : mass of the proton
p= 4.96 X 10^-19 kg.m/s.
We replace this data in the Equation (1):
Answer: The velocity of the proton is

Carrying capacity is the maximum population size than habitat or environment can sustain indefinitely because it is able to replenish its resources. Limiting factors to carrying capacity of an ecosystem include resources such as food, water, and space.
