Answer:
im pretty sure a collision is a transfer of momentum.
Explanation:
hope this helps :)
The circuit shown has a battery and two resistors, with R1>R2. Which of the two resistors dissipates the larger amount of power? Explain
Rank in order, from largest to smallest, the three currents I1 TO I3. And explain why?
The two batteries are identical and the four resistors all ahve exactly the same resistance.
a) Compare change in V(ab), V(cd), and V(ef). Are they all the same? In not, rank them in decreasing order. Explain you reasoning
b) Rank in order, from largest to smallest, the five currents I1 to I5, and ezplain why
Answer:
0
Explanation:
Given:
initial velocity, 
distance of telescope from the launch pad, 
time after which the observation starts, t = 3 min.
Now, from the equation of motion:
Which indicates that the after the given time the rocket would have fallen down on the ground if it did not had an acceleration of its own.
the first one Is right answer
Answer:
T = 125.30C
Explanation:
Using Stefan-Boltzmann law
P/A = e* Stefan-Boltzmann constant * T^4
Where p= radiant power in watts
e = emissivity
T = Temperature in kelvin
A= Surface area of the object measured in m^2
Considering that after painting the object have the radiant power then
0.83* A* Stefan-Boltzmann constant *(337.1^4) = 0.46 * A* Stefan-Boltzmann constant * Tnew^4
Cancelling the common terms yields
0.83*(337.1^4) = 0.426*Tnew^4
Fourthroot(0.83*(337.1^4)) = Tnew
Tnew = 398.3k = in degree Celsius 125.3
