Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines.
Explanation:
Muscles are attached to bones; they help us walk and run and smile. All the bones in our body make up our skeleton from the top of our skull to the tips of the phalanges at the end of our toes. Muscles stretch across our bones and are attached with tendons.
Answer:
6 beats
If one fork beats once and another twice in the same time period
you would hear 1 beat. (Same for 2 and 3 beats).
The general effort force equation for block and tackle to raise or pull a load can be expressed as
<span><span>S=<span>F/<span>μn</span></span></span>
</span>
where
<span>S
</span> is the effort force,
<span>F
</span> is the load force (often the weight of the object to be moved),
<span>μ
</span> is the mechanical efficiency of the system (1 in an ideal, massless, frictionless system of pulleys), and
<span>n
</span> is the number of ropes between the sets of pulleys.
Answer:
Volume of the wood = 120.615 cm3
Density of the wood = 0.457 g/cm3
Explanation:
By definition, density is the mass of a substance per unit volume and its units are kg/m3, g/l etc.
Volume of a cuboid = length * breadth * height
Length = 8.5 cm
Breadth = 3.3 cm
Height = 4.3 cm
Volume of the wood = 8.5 * 3.3 * 4.3
= 120.615 cm3
Mass of the wood = 55.120 g
Density = mass/volume
= 55.120/120.615
= 0.457 g/cm3
= 457 kg/m3
