Answer:
l=3.5 x 10^-10m
Explanation:
just toook the test got it right good luck!
Q = mc<span>∆t, where:
q = energy flow
m = mass, 120 000 g
c = specific heat capacity, 4.81 J/gC
</span><span>∆t = change in temperature, ~75 (100 - 25, which is room temperature)
Substituting in the values, we get:
q = 120000 x 4.81 x 75 = 43290000 Joules = 43.29 MJ
Hope I helped!! xx

Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
Train has the most momentum if they were all traveling 50 mph
<u>Explanation:</u>
- A train can have the most momentum even if it is moving slowly because it has a large mass if they were all traveling 50 mph.
- In simple words, momentum can be described as the amount of motion of a moving body, estimated as a product of its mass and velocity.
- <u>Momentum= mass x velocity</u>
