For this problem, we use the conservation of momentum as a solution. Since momentum is mass times velocity, then,
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
where
v₁ and v₂ are initial velocities of cart A and B, respectively
v₁' and v₂' are final velocities of cart A and B, respectively
m₁ and m₂ are masses of cart A and B, respectively
(7 kg)(0 m/s) + (3 kg)(0 m/s) = (7 kg)(v₁') + (3 kg)(6 m/s)
Solving for v₁',
v₁' = -2.57 m/s
<em>Therefore, the speed of cart A is at 2.57 m/s at the direction opposite of cart B.</em>
Answer:
The total number of charge pair without double counting is 6.
Explanation:
Given that,
Number of proton = 2
Number of electron = 2
We need to calculate the total number of charges in Hydrogen atom
Using formula for number of charges
Number of charge in pair is
We need to calculate the total number of possible combination of pairs without double counting
Using formula of combination
Where, n = number of charges
r = number of charges per pair
Put the value into the formula
Hence, The total number of charge pair without double counting is 6.
The condition for maximum intensity is the same as that for a double slit. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. For a diffraction grating with lines/mm = lines/inch, the slit separation is d = micrometers = x10^ m.
Answer: the washer would slow down depending on how strong the magnet is even though the gravitational pull is the same. the change would be .6
Explanation: i don't really get it
Since this a position vs time graph, the velocity will be the slope of the line.
(5-3) / (3-0)
2/3 m/s
.6666 m/s
