Tigers and crocodiles are more closely related than tigers and sharks. Which statement about shared characteristics best supports this statement?
Answer: Crocodiles and tigers both have four legs
Explanation: Even when sharks and tigers are both meat eaters, the question is about similarities between tigers and crocodiles, so D is out. A is about crocodiles and sharks, so it's out also. B suits for sharks too, so it's out too. C is the most suitable answer, because both animals have four legs, which means that they belong to the group of quadrupede animals.
Answer:
Crocodiles and tigers both have four legs

A sealed can of soda contain a pressure of 1.15 atm at 23°C. What is the new pressure at 79 °C? Report your answer to the hundredths place (two decimal places) You do NOT need units in your answer
Answer:
P₂ = 1.37
Explanation:
Given data:
Initial pressure = 1.15 atm
Initial temperature = 23°C (23+273= 296 K)
Final pressure = ?
Final temperature = 79°C (79+273=352 K)
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.15 atm / 296 K = P₂/352 K
P₂ = 1.15 atm × 352 K / 296 K
P₂ = 404.8 atm. K /296 K
P₂ = 1.37 atm

Explanation:
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. first question Natural non-living things: They are found in nature and are not made by man. Examples: Sun, moon, stars, sky, clouds, rocks, mountains and many more. Man-made non-living things: They are made by man. Examples: Toys, chairs, tables, beds, houses, buildings, trains and many more. second question Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". third question. Sedimentary. fourth question and sorry I can't answer the last :(
Explanation:
Which characteristic is related to kinetic energy but not potential energy
Answer:
kinectic is movement and potential is still
Explanation:
While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.
Answer:an object’s speed
Explanation:
Match each form of energy with its correct description.
mechanical
involving the motion of atoms
chemical
involving electrical charges
thermal
involving the position and motion of
an object
electrical
involving energy stored in chemical

Answer
involving electrical charges: electrical
involving energy stored in chemical

involving the position and motion of
an object: mechanical
involving the motion of atoms: chemical

WILL GIVE BRAINLIEST Pam and Caroline determined the mass and volume of a piece of metal to be 34.16 g and 11.3 mL respectively. Determine the density of the metal. (Please show work and use significant figures.
Answer:
0.303kg/m
Explanation:
Density=m/v where m is mass
and v is volume
we then convert m in grams to kg
= 34.16/1000
=0.0342kg
converting ml to m
=11.3/100
=0.113m
then density=0.0342/0.113
=0.303kg/m
Sunlight heating the sand on the beach on a hot summer day is an example of
a. conduction
b. convection
c. radiation
d. none of these
Answer:
c
Explanation:
Sunlight heating the sand on the beach on a hot summer day is an example of radiation which is electromagnetic radiation.
What is electromagnetic radiation?
The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

A photon has an energy of 2.34x10-28 J. What is its frequency?
Answer:
f = 3.53×10⁵ s⁻¹
Explanation:
Given data:
Energy of photon = 2.34×10⁻²⁸ J
Frequency = ?
Solution:
h = 6.63 ×10⁻³⁴
Formula:
E = hf
2.34×10⁻²⁸ J = 6.63 ×10⁻³⁴ × f
f = 2.34×10⁻²⁸ J / 6.63 ×10⁻³⁴ Js
f = 0.353×10⁶ s⁻¹
f = 3.53×10⁵ s⁻¹

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.
Explanation:
Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.
Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.
In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.
The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.
The independent variable is the variable that you measure.

In what way do the atoms in the same row of the Periodic Table increase from left to right?
Answer:
As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.
