It is a scaler because it’s only fully describes by a magnitude and a numerical alone
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
<h2>When a mass on a spring that has been compressed 0.1 m has a restoring force of 20 N , then the value of spring constant (k) :- </h2><h2>200 N/m</h2>
Explanation:
Spring Constant :
According to Hooke's law, The force required to compress or extends spring is directly proportional to the distance it is compressed or stretched.
Given
x = -0.1 m
F = 20 N
F - -kx
k = -f/x
= -20 / -0.1 = 200 N/m
The value of spring constant is 200 N/m.
