Answer:
1] 8500000 = <u>8.5 × 10⁶</u>
2] .000072 = <u>7.2 × 10⁻⁵</u>
3] 5.3 × 10⁴ = <u>53000</u>
4] 2.8 × 10⁻³ = <u>0.0028</u>
5] Velocity = 
V = 
<u>V = 5 m/s</u>
6] Acceleration = 
A = 
A = 
<u>A = 3 m/s²</u>
Answer:
219.9208 m
Explanation:
The new length is given by
New length= Original length *(1-Temperature change*coefficient of
thermal expansion of steel)
Here, the change in temperature is 
New length= 
Therefore, the new length will be 219.9208 m
This is because of of the heating effect of a current. The glow is a result of current passing through the filament. The current experiences resistance as a result heat is generated. When resistance is at zero, there potential differences is not needed hence temperature generated will be at a constant.
Answer:
Wavelength is the distance between from one crest to another crest or from one trough to another trough. The amplitude is the distance from the midpoint to the crest or trough. Crest is the highest point of the or a wave. Tough is the lowest point of the or a wave. Rest position is the position where it lies on the midpoint line.
Explanation:
I need a diagram to label these parts.
