The voyage of the H.M.S what important because
yaroslaw [1]

C. Physicalist chemist and biologist conducted experience in gather collection that changed existing scientific knowledge about the oceans

Explanation:

The voyage of Her Majesty's Ship was highly important because it furnished scientists with rich evidence about a lot of phenomenon under study and this changed existing scientific knowledge about the ocean.

  • H.M.S II was an expedition to study and map the ocean floor using some sophisticated and newer devices.
  • It was through this expedition that the theory of plate tectonics was modified and became a theory
  • The bathymetry of the ocean floor was also carried out.
  • The mid-oceanic ridge was discovered through the expedition.
  • Some rare species of organisms were also obtained from the ocean floor in this process.
  • The H.M.S second expedition after the world war was very crucial and helped furthered scientific knowledge about the oceans.

the coefficient of kinetic friction between a couch and the floor is 0.65. if the couch has a mass of 42 kg and you push it with
Anna [14]

Explanation:

The net force along the horizontal direction is

\sum{F_x} = F_{applied} - f

where f is the frictional force. We can find the frictional force by looking at the vertical forces acting on the couch:

\sum{F_y} = N - mg = 0 \Rightarrow N = mg

From the definition of frictional force,

f = \mu{N} = \mu{mg} = (0.65)(42\:\text{kg})(9.8\:\text{m/s}^2)

\:\:\:\:= 267.5\:\text{N}

Therefore, the net force on the couch is

\sum{F_x} = 600\:\text{N} - 267.5\:\text{kN} = 332.5\:\text{N}

The emission of a Beta particle has the effect of?
Zarrin [17]

Answer: No change in mass

Explanation:

Beta-emission: In this process, a neutron gets converted into a proton and an electron. The electron is referred to as a beta-particle. The beta particle released carries a charge of -1 unit and has negligible mass.

General representation of an element is given as: _Z^A\textrm{X}

Z= Atomic number

A = mass number

X = chemical symbol of element

_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta
