Answer:
8 kg*m/s and 2m/s
Explanation:
momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.
4kg*12m/s = 48 kg*m/s
4kg*10m/s = 40 kg*m/s
48kg*m/s - 40 kg*m/s = 8kg*m/s
Fast-moving currents of air that occur above the friction layer are called jet streams.
A caldera is a large cauldron-like depression that forms following the evacuation of a magma chamber or reservoir. When large volumes of magma are erupted over a short time, structural support for the crust above the magma chamber is lost, and the entire structure caves in and forms a large bowl-like shape.
Answer:
505.62 mm
Explanation:
Young's modulus of a material is given by,
Stress is the force experienced by the material per unit area (which is why stress has the same units as pressure).
Strain is the ratio between the change in length/area/volume to the original length/area/volume of the material (and hence a dimensionless quantity). Basically, it gives us a measure of the change in dimensions due to the stress experienced.
So, for the given problem,
or, (since we need to find the compression of the bone at the critical stress point)
or,
Answer:
D. Satin Cloth
Explanation:
i thought it said glass, not grass lol
satin it the smoothest surface and therefore the least amount of friction.
