A small cart and one of larger mass collide and rebound off each other. The carts were initially moving with the same speed. Whi

Natalka [10]

the collision is elastic as the carts rebound off each other.

by conservation of momentum, the small mass will have a larger change in velocity.

so the ans is The small cart changes its velocity the most.

Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.

Nuetrik [128]

Wow ! This question reads like it might have come from one of
Faraday or Maxwell's original laboratory notebooks.

Choice-A is the correct one, when you consider what "conductance"
means. Conductance is just 1/resistance .

So when you see
"A) Current is proportionate to the conductance of the circuit and
precisely proportional to the voltage applied across the circuit."

what it's saying is
"Current is inversely proportional to the resistance of the circuit, and
directly proportional to the voltage applied across the circuit."

If you write the equation for all those words, it looks like

I = V / R

and that's correct.

You are in a hot air balloon, 350 m above the flat Texas plains. You look out toward the horizon. How far out can you see--that

pshichka [43]

Refer to the diagram shown below.

x = the distance (horizon) that you can see from the balloon,

Because the radius of the earth is 6400 km, and the balloon is 350 n above the earth's surface, therefore
h = 6400 + 0.350 = 6400.35 km.

From the Pythagorean theorem, obtain
x = √(6400.35² - 6400²) = 66.934 km

Answer: Your horizon is 66.934 km (or 66,934 m)
