How big is a ton? That is, what is the volume of something that weighs a ton? To be specific, estimate the diameter of a 1-ton r

ock, but first make a wild guess>: will it be 1 ft across, 3 feet, or the size of a car? (Hint: Rock has mass er volume about three times that of water, which is 1 kg per liter(10^3cm^3) or 62lb per cubic foot) ...?

<span>Short ton is equal to 2000 lb. A metric tonne is equal to 1000 kilograms.

T</span>o get the volume of a rock you should divide the mass (1000 kg) by the density. Assume the density is three times of water. You can assume the rock is a sphere or cube to get the approximate dimension from the volume. 

<span>The density of water is 1000 kg / m^3

Alinara [238K]

Answer:

D. To ensure common resources are not overused

Explanation:

  • The article of the antarctic treaty VII provides that all the consultative parties have a right to designate the observers and to undertake the inspection as of the protocol 14 of that provides the protection of the environment and to safeguard the ecological system.  
  • Since 1963, about 9 inspections have been conducted by the teams by visiting the stations, facilities, the vessels, and the protected areas across a wide area of East Antarctica, The most recent Antarctica expedition treaty inspection was done in Dec 2016.

A wire 95.0 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 40.0 mm
qaws [65]

Answer:

0.1040512455 N

36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

0.05925 N

29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

Explanation:

I = Current

B = Magnetic field

Separation between end points is

l=\sqrt{40^2+55^2}\\\Rightarrow l=68.00735\ mm

Effective force is given by

F=IlB\\\Rightarrow F=5.1\times 68.00735\times 10^{-3}\times 0.3\\\Rightarrow F=0.1040512455\ N

The force is 0.1040512455 N

tan\theta=\dfrac{55}{40}\\\Rightarrow \theta=tan^{-1}\dfrac{55}{40}\\\Rightarrow \theta=53.97^{\circ}

The angle the force makes is given by

\alpha=\theta-90\\\Rightarrow \alpha=53.97-90\\\Rightarrow \alpha=-36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

The direction is 36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

F=IlB\\\Rightarrow F=4.9\times \sqrt{20^2+35^2}\times 10^{-3}\times 0.3\\\Rightarrow F=0.05925\ N

The force is 0.05925 N

tan\theta=\dfrac{35}{20}\\\Rightarrow \theta=tan^{-1}\dfrac{35}{20}\\\Rightarrow \theta=60.26^{\circ}

\alpha=\theta-90\\\Rightarrow \alpha=60.26-90\\\Rightarrow \alpha=-29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

The direction is 29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

The nucleus of most atoms is composed of which of the following sub-atomic particles? (A) tightly packed neutrons
solmaris [256]

Answer:

(B) tightly packed protons and neutrons

Explanation:

  • Nucleus of any atom is the dense central part of any atom.
  • It consists of two sub-atomic particle namely proton and neutron.
  • These sub-atomic parts are tightly packed in nucleus which makes the nucleus dense .
  • This dense nucleus is responsible for most of the mass of atom.
  • The atomic mass for any atom is decided by sum of  the mass of proton and neutron

Thus, correct answer is

(B) tightly packed protons and neutrons
