Index fossils are the remains of species that were once abundant and

Answers

Answer 1

Answer: The question is asking to complete the sentence: index fossils are the remains of species that were once abundant and (...). Index fossils are used to be able to see that a certain layer of soil was from a particular period of time. This means that they could not have lived long - just for a short period in the geological history. Typically, index fossils were also geographically widespread, but it's not always the case

Answer 2

Answer:

Answer:

Geographically Widespread

What kind of energy does a rubber band have when it is stretched? a. elastic potential energy

b. gravitational potential energy

c. kinetic energy

d. chemical energy

Answers

Elastic potential energy. When you stretch a rubber band it has the "potential" to do work, to fly in a given direction. In doing so it changes it's elastic potential energy to kinetic energy.

Answer:

elastic potential energy

Which statement correctly describes mass-energy equivalence?

Answers

Mass-energy equivalence, as articulated in Einstein's E=mc² equation, indicates that mass can be converted to energy and vice versa. This theory has current practical applications such as the operations in nuclear power plants and in explaining natural phenomena like solar energy generation.

The principle describing mass-energy equivalence is most accurately presented by Albert Einstein's mass-energy equivalence equation, E = mc². In some processes, according to this equation from the theory of special relativity, mass can be converted into energy, and vice versa. This means that we consider mass to be a form of energy, not something distinct.

Examples of this conversion are seen in everyday life and nature. For instance, the sun's energy, the energy from nuclear decay, and even the heat in Earth's interior can be traced back to the mass-energy equivalence. Nuclear power plants and nuclear weapons provide practical examples of mass being converted into energy. In these cases, a tiny fraction of mass is annihilated to produce energy expressed as nuclear radiation.

Therefore, the theory of conservation of mass was supplanted by the more comprehensive theory of conservation of mass-energy which includes the phenomenon of mass-energy equivalence, and is described mathematically in the equation E= mc².

In a given circuit, the supplied voltage is 1.5 volts. One resistor is 3 ohms and the other is 2 ohms. Use Ohm's law to determine the current in the circuit. 0.3 amps 1.5 amps 7.5 amps 3.3 amps The purpose of a fuse or circuit breaker is _____. to speed up the current to slow down the current to stop current that is flowing too fast to stop current that is flowing too slow

Answers

Part #1:
You haven't mentioned whether the resistors are in series
or in parallel. It's going to make a difference.

-- If the resistors are in series, then their net effective resistance
is their sum.

   (3 ohms) + (2 ohms) = 5 ohms.

Current in the circuit is

(supply voltage) / (total resistance)

   =    (1.5 volts) / (5 ohms) = 0.3 ampere .

-- If the resistors are in parallel, then their net effective resistance
   is
   (their product) / (their sum)

      = (1 ohms x 2 ohms) / (1 ohm + 2 ohms)

    =    (2 ohms²) / (3 ohms) = 2/3 ohm .

Current in the circuit is

(supply voltage) / (total resistance)

   = (1.5 volts) / (2/3 ohm) = 1.0 ampere .

I guess your resistors are in series, because 0.3 amp
is one of the choices but 1.0 amp isn't.
______________________________________

Part #2.
When it comes to talking about electric current, the terms
"speed up", "slow down", "fast", and "slow" are somewhere
between meaningless and absurd.

The purpose of a fuse or circuit breaker is to shut down a current
that is too great ... too great a magnitude, too many electrons all
trying to crowd their way through the wire at the same time, like
100 lines of ants all carrying bread crumbs through a straw and
back to their hole, when there was only supposed to be one or
two lines.

Speed has nothing to do with it. All electric currents flow through
wires at the same speed, at least in high school. It's a matter of
Amperes, which has nothing to do with speed.

What type of force pulls in two opposite directions?a. tension (associated with normal faults)
b. normal (associated with longitudinal faults)
c. transform (associated with transform faults)
d. compression (associated with reverse faults)
Which is not a type of fault?
a. normal
b. reverse
c. diagonal
d. transform

Answers

Answer

a. tension (associated with normal faults)

c. diagonal

Explanation

A pull of spring or of string on both ends of an object is called tension. So for the question one, the answer is tension (associated with normal faults)

There are three types of faults. Faults are produced by stress or strain by moving plates. These faults are: normal faults, reverse faults and transcurrent or Strike-slip. Strike-slip faults can also be called transform fault. The answer to the second question is c. diagonal.

Answer:

Tension Force (associated with normal faults)

Explanation:

As we know that tension force is an internal force between the molecules which opposes the tendency of molecules to separate out.

The tension force of string is always in opposite directions at two ends of string and it is always along the length

Answer:

Diagonal

Explanation:

As we know that there are four types of vaults

1) Normal vaults

2) Longitudinal vaults

3) Reverse vaults
