Answer:
That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.

Explanation:
Copper is commonly used as an effective conductor in household appliances and in electrical equipment in general. Because of its low cost, most wires are copper-plated. You will often find electromagnet cores normally wrapped with copper wire
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.
Answer:8540 kg-g/s
Explanation:
Given
mass of blue car 
velocity of blue car 
mass of the truck 
speed of truck 
After collision they stick and lock together
Let v be the velocity of combined system at angle \theta from vertical
Conserving momentum in east direction
------1
Conserving Momentum in Y direction
-------2
squaring and then adding 1 & 2 we get
v=10.95 m/s
initial momentum of car
Answer:
They have mass is always true.
