The mass of the pendulum does not affect the period and frequency
The period can be determined using the formula:
T = 2π √(L/g)
where L is the length of the rope
and g is the acceleration due to gravity = 9.8 m/s2
Plugging in the values:
T = 2π √(5/9.8)
T = 10π/7 = 4.49 s
And for the frequency:
f = 1/T
f = 1/4.49
f = 0.22 Hz
Lucas rode 1,000 meters b/c
2 klm is = to 2000 meters.
and 1/4 of 2000 meters is 500 meters but then he had
to turn back to go home so that's another 500 meters and in total he rode 1,000 meters.
Answer is 64
64 = 8² ← <span>perfect square
64 = 4</span>³ ← <span>perfect cube</span>
The surface area of the pyramid is 576.
<em>The square base is 144. It's just a square, so you multiply 12 (length) and 12 ( width) , which equals 144. </em>
<em>Then you find the area of one of the triangles. The equation to find triangles goes like this: 0.5 x B (base: 12) x H (height: 18). That would be 6 x 18 which is 108.</em>
<em>Since you got the area of 1 triangle and there are 4 triangles you have to multiply 108 by 4. That'll give you 432.</em>
<em>SO since you have the area of all the triangles and the square base the last thing you have to do is just add it all up. </em>
<em>The area of the triangles plus the area of the square base = the surface area.</em>
<u>432 cm + 144 cm =576 cm.</u>
