The answer to the question is friction
Answer:
hello the answer is 47m/s
Answer:
Hence the weight of the person on the moon is 162.4, and the value of g used is 1.624 m/s²
Explanation:
from the question,
W = mg........................ Equation 1
Where W = weight of the man on Earth, m = mass of the man, g = acceleartion due to gravity of the man
make m the subject of the equation
m = W/g.............. Equation 2
Given: W = 1000 N,
Constant: g = 10 m/s²
Therefore,
m = 1000/10
m = 100 kg
Weight on the moon
W' = mg'
W' = 100(1.624)
W' = 162.4 N.
Hence the weight of tthe person on the moon is 162.4, and the value of g used is 1.624 m/s²
Answer:
The spacing is 5.15 μm.
Explanation:
Given that,
Electron with energy = 25 eV
Wave length = 0.25 nm
Separation d= 0.16 mm
Distance D=3.3 m
We need to calculate the spacing
Using formula of width
Put the value into the formula
Hence, The spacing is 5.15 μm.
It will be option G because from gas to solid the kinetic energy decreases which makes the molecule more stable because of this the solid is stable. so yeah.
