The volume of the block of wood is given by length × width ×height
= 2.75 × 4.80 × 7.5
= 99 cm³
Density is given by mass/volume
Thus = 84.0 g/ 99 cm³
= 0.848 g/cm³
Hence; since the block is less dense than water (1 g/cm³) it will float
Answer:
The process of soil formation generally involves the downward movement of clay, water, and dissolved ions, and a common result of that is the development of chemically and texturally different layers known as soil horizons. The typically developed soil horizons, as illustrated in Figure 5.16, are: O — the layer of organic matter A — the layer of partially decayed organic matter mixed with mineral material E— the eluviated (leached) layer from which some of the clay and iron
Explanation:
i'm built different
jetliner is moving with speed 146 mi/h
now we will have
now if it moves with this speed for 1.5 s
so the displacement for above time
now the deceleration of jet is given as
now by kinematics
so total displacement is given as
so displacement will be 555.7 m
Answer:
The impulse is -20kg m/s.
Explanation:
given mass of ball = 0.4 kg
The ball is moving towards left with the initial velocity = 30m/s
The momentum in left direction P1 = mv1
= (0.4)(30)
= 12 kg m/s
The given velocity towards right = -20 m/s ( negative sign shows inverse direction)
Momentum towards right, P2 = mv2
P2 = (0.4)(-20)
P2 = -8 kg m/s
The Impulse = change in momentum
= P2 –P1
= -8-12
= -20 kg m/s
