S= 343m/s
F=256Hz
WL= 343ms/256-1
WL=V/F
= 1.339844m
<u>We are Given:</u>
Mass of the block (m) = 500 grams or 0.5 Kg
Initial velocity of the block (u) = 0 m/s
Distance travelled by the block (s) = 8 m
Time taken to cover 8 m (t)= 2 seconds
Acceleration of the block (a) = a m/s²
<u>Solving for the acceleration:</u>
From the seconds equation of motion:
s = ut + 1/2* (at²)
<em>replacing the variables</em>
8 = (0)(2) + 1/2(a)(2)²
8 = 2a
a = 4 m/s²
Therefore, the acceleration of the block is 4 m/s²
M=2.45 because you multiply out the equation on the right and divide by 10
Wind<span> power
holds great promise for the united states because of the great wind power (capacity),
and experts believe wind energy could meet as much as 20 percent of the
nation’s energy needs
. Texas is the state with most wind capacity. On the second place is Iowa and oh the third place Oklahoma. The wind farms produce clean energy that does not harm the environment.</span>
