Answer:

Substances that enhance the flow of current are called conductors

Substances that inhibit the flow of current are known as insulators

Substances that neither conduct nor inhibit are called semiconductors

Explanation:

  • Substances that enhance the flow of current are called conductors because they allow electrical charges to pass through them.
  • Substances that inhibit the flow of current are known as insulators because they prevent the flow of electrical charges through them.
  • Substances that neither conduct nor inhibit  flow of current as well are called semiconductors. These substances although they cannot conduct of prevent the flow of current, in certain conditions they can be made to conduct and reversed as well.

Absolute pressure in tank is P1 = 260 kPa and local ambient absolute pressure is P2 =100 kPa. If liquid density in pipe is 13600
Pavlova-9 [17]

Answer:

1.176m

Explanation:

Local ambient pressure(P1) = 100 kPa

Absolute pressure(P2)=260kPa

Net pressure=absolute pressure-local ambient absolute pressure

Net pressure=P1(absolute pressure)-P2(local ambient absolute pressure)

Net pressure=260-100=160kPa

Pressure= ρgh

160kPa=13600*10*h

h=\frac{160000}{136000}

h=1.176m

Imagine you were able to throw a ball in a frictionless environment
such as outer space.  Once you let go of the ball, it will travel forever
in a straight line, and at a constant speed.  (At least until it bumps into
something.)

A car accelerates down the road.  The reaction to the tires pushing
on the road is the road pushing on the tires.

Which statement describes a chemical property related to the particles that make up the material
Stells [14]

Answer: The correct answer would be C.  Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.

Explanation: All the other ones are chemical changes because a new substance is formed.

A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling west at 20.0 m/s. The cars stick together. What is
andriy [413]

Answer:

17.27m/s

Explanation:

M1U1 + M2U2 = (M1+M2)V

(900x15) + (750 x 20) = (900+750)V

13500+15000 = (1650)V

28500 = 1650v

V = 28500/1650 = 17.27m/s

V = 17.27m/s

A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing e
sergij07 [2.7K]

Answer:

9.60 m/s

Explanation:

The escape speed of an object from the surface of a planet/asteroid is given by:

v=\sqrt{\frac{2GM}{R}}

where

G is the gravitational constant

M is the mass of the planet/asteroid

R is the radius of the planet/asteroid

In this problem we have

\rho = 2.02\cdot 10^6 g/m^3 is the density of the asteroid

V=3.09\cdot 10^{12}m^3 is the volume

So the mass of the asteroid is

M=\rho V=(2.02\cdot 10^6 g/m^3)(3.09\cdot 10^{12} m^3)=6.24\cdot 10^{18} g=6.24\cdot 10^{15} kg

The asteroid is approximately spherical, so its volume can be written as

V=\frac{4}{3}\pi R^3

where R is the radius. Solving for R,

R=\sqrt[3]{\frac{3V}{4\pi}}=\sqrt[3]{\frac{3(3.09\cdot 10^{12} m^3)}{4\pi}}=9036 m

Substituting M and R inside the formula of the escape speed, we find:

v=\sqrt{\frac{2(6.67\cdot 10^{-11})(6.24\cdot 10^{15})}{(9036)}}=9.60 m/s
