There is no SI "base unit" of density.
(Any unit of mass) divided by (any unit of volume) is
a valid unit of density.
The units of density that are seen most often are
(gram per cm³) and (kgm per meter³) .
The answer would be
C. Rods and Cones
Answer:
33.33 seconds
Explanation:
= Initial length pulled = 20 cm
b = Damping constant = 0.015 kg/s
k = Spring constant = 4 N/m
m = Mass of glider = 250 g
Time period is given by
Using exponential decay formula
Final amplitude = Initial times decay
The time taken is 33.33 seconds
Explanation:
G. gamma rays because they are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
hope this helps you
have a nice day:)
<span>This projectile has been thrown in an oblique movement, so it’s moving in x and in y at the same time. Vy varies due to gravity, and Vx is a constant as there is no gravity in the horizontal direction. In order to calculate Vx, you have to use the angle:
Vx=V*cosa=12m/s*cos(14.2)= 11.6m/s
So now you should use Vx the same way it is used in a uniform linear movement.
d=v*t
dx=vx*t
t=dx/vx=7m/(11.6m/s)=0.603s</span>
