Answer:
your answer for this question is B
Answer:
d = 3.56 x 10⁻⁴ m = 0.356 mm
Explanation:
The diameter of the aperture can be found using the following formula:
where,
y = distance between dark rings = 1.65 mm = 1.65 x 10⁻³ m
λ = wavelength = 490 nm = 4.9 x 10⁻⁷ m
L = distance between screen and aperture = 1.2 m
d = diameter of aperture = ?
Therefore,
<u>d = 3.56 x 10⁻⁴ m = 0.356 mm</u>
Two in middle, so Newton's 2nd law. Equal and opposite force (both are moving). You have to assume no friction since it's an ice rink.
<span>Skater 1: 45kg 0.66m/s </span>
<span>Skater 2: xkg 0.81ms/ </span>
<span>Since force is equal, 45*0.66=x*0.81 </span>
<span>Solve for x. </span>
<span>So the answer would be 36.7kg</span>
Cricket chirping increases with an increase temperature.
the higher the temperature the higher the chirping
