More empty space in mass !!
The answer is option D.
Area of sheet, A1 = length × breadth
= (8.5 inch * 2.54 cm) ×11 inch * 2.54 cm)
= 603.22
Now, Mass of sheet, M1 = 4.50 gms
Thus, Area of sheet A2, = 1
And, Mass of sheet, M2 = ?
Thus, Mass of M2 =
= 0.0073
Answer:
Explanation:
easy way
when system is all kinetic energy, velocity is at a maximum
E = ½mv²
v = √(2E/m) = √(2(25)/0.5) = √100 = 10 m/s
harder way
ω = √(k/m) = √(80/0.5) = √160 rad/s
When the system is entirely spring potential, the amplitude A is
E = ½kA²
A = √(2E/k) = √(2(25)/80) = 0.790569... = 0.79 m
maximum velocity is ωΑ = 0.79√160 = 10 m/s
Answer:
my brainly answer got deleted for no reason but its velocity thats the name of speed in 1 direction
