An iron pot is mostly magnetic
Answer:
-19.4 m
Explanation:
Given:
a = -1.77 m/s²
t = 3.33 s
v = -8.77 m/s
Find: Δx
Δx = vt − ½ at²
Δx = (-8.77 m/s) (3.33 s) − ½ (-1.77 m/s²) (3.33 s)²
Δx = -19.4 m
Answer: The De broglie's wavelength is 1.45×10^-14m
Explanation:
Using De broglie's equation
λ= h/mv
Where h= Planck's constant = 6.6×10^-34Js
m= mass in kilogram = 3.8×10^-28kg
V= velocity = acceleration ×time =
2.4×10^7 ×5
V= 1.2×10^8m/s
λ= is the De broglie's wavelength
λ= 6.6×10^-34Js /(3.8×10^-28kg ×1.2×10^8)
λ= 1.45×10^-14m
Therefore ,De broglie's wavelength=
1.45×10^-14m
Answer:
Mulching often acts as a soil insulator that helps to maintain soil moisture while promoting the growth of grass and plants. It is used as a temporary soil stabilizer. Moreover, with proper application, mulching can help to keep soil in place for a few days.
