Two sphericle objects have masses of 8000 KG and 1500 KG their centers are separated by a distance of 1.5 M find the gravitational attraction between them
Answers
if I am correct I think its I'm am not 100 percent sure but I think this should be the answer
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N
Using the formula of gravitational attraction
F = G*M1M2/d²
where G = 6.67 * 10⁻¹¹ Nm²Kg⁻²
M1 = 8000Kg
M2 = 1500 Kg
F = 6.67 * 10⁻¹¹ * 8000 * 1500 / (1.5)²
F = 3.56 * 10⁻⁴ N
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answers
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.

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
Answers
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 Covalent bonds are insoluble in water (H2O) , but covalent compounds are. This is because some organic compounds (covalent) contain the polar −OH group which can bond to a hydrogen ion to form water.
BRAINLIEST! Please help me answer the following questions:
1) How do you find the valency of an element?
2) How do you determine if an element is nuetral/an isotope/ or an ion?
If you could help with 1 or both questions I would really appreciate it :)
Answers
Explanation:
1) from the periodic table for example if u looking for K it is from the group 1A so the valancey = +1 that is mean it loses one electron to reach a stable state. and this applied for the 1A , 2A, 3A groups.
if u looking for N it is from group 5A so its valency is -3
so it gain 3 electrons to reach a stable state to complete its orbital to 8 electrons. this applied to 5A, 6A,7A
for the transition metals and simimetals other rules.
2) neutral if the element does not hold any charge like
H2, O2, N2, Fe, Au, Cu ...
isotope : if the 2 elements have same symbol and atomic number but they differ in the mass number because the have different numbers of neutrons.
if the element is charged then it is considered as an ion ex: Fe2+ then it is iron cation ( +ion)
F- then it is fluoride anion (-ion)

The _____ law of thermodynamics states that when two objects of different temperature are in contact, heat energy will flow from the hotter to the cooler object.
Answers
Answer:
Second.
Explanation:
There are four types or kinds of the laws of thermodynamics, but in this question we are actually considering the second law of thermodynamics.
The second law of thermodynamics, in a simple sense means that energies can flow in an equilibrate manner. It can also be stated as the total entropy of the universe. The second law is normal refer to as Law concerning Entropy.
Thus, filling the gap in the Question above. Note that the word written in capital letters is the missing word.
"The SECOND law of thermodynamics states that when two objects of different temperature are in contact, heat energy will flow from the hotter to the cooler object."

Answers
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

A photon has an energy of 2.34x10-28 J. What is its frequency?
Answers
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
Brian is making a cake for his friend's birthday. He combines the ingredients for the cake and then pours the batter into two pans and bakes them for 45 minutes in the oven. While the pans are in the oven, he combines butter, sugar, and milk and mixes them together to make the icing. What type of changes created the cake and the icing?
A. Both the icing and the cake are formed by physical changes.
B. Both the icing and the cake are formed by chemical changes.
C. The icing is formed by a chemical change and the cake is formed by a physical change.
D. The cake is formed by a chemical change and the icing is formed by a physical change.
Answers
Answer:
it’s D.The cake is formed by a chemical change and the icing is formed by a physical change
Explanation:
It’s because when the cake was baking there was nothing physical about it so it was a chemical change the icing is formed by a physical change because all you did was mix three ingredients together
The type of changes that created the cake and the icing is;
Option D; The cake is formed by a chemical change and the icing is formed by a physical change.
This is about understanding type of changes in chemistry.
Physical change is defined as a change that affects the form of a compound or element but it doesn't affect its' chemical composition.Meanwhile, chemical change is defined as a change that affects the composition of a compound and a new substance is formed.Now, for brian's cake he has combined raw ingredients into two pans and bakes the cake. For the cake to be baked, it means the ingredients mixed have changed from liquid to solid and also a new substance has been formed. Thus, we can say that the cake was formed from chemical change.Meanwhile, the icing was formed by physical change because it did not undergo any chemical process and no new substance was formed as only butter, sugar and milk were mixed together.Read more at; https://brainly.com/question/19046658
