Answer:
4.9 N/m
Explanation:
m = 0.1 kg
x = 0.2 m
Let k be the spring constant.
As teh weight is balanced by the tension in the spring
Weight = force = mass x acceleration due to gravity
F = m x g = 0.1 x 9.8 = 0.98 N
This force si balanced by spring force
F = k x
Where, k be the spring constant and x be the displacement in spring
0.98 = k (0.2)
k = 4.9 N/m
Answer:
b. equal in size and opposite in direction
Answer:
1800 m/s
Explanation:
The equation is v = fλ
λ= 0.75
f = 2400 Hz
V = 2400 × 0.75
V = 1800 m/s
[ you did not give units for wavelength, I assumed it would be m/s]
Luminosity : The quality of being luminous
emitting or reflecting light
I hope that's help !
