Suppose a high-flying jumbo jet with a mass of 45,000 kg cruises at constant velocity when the thrust of its engine is a constant 80,000 N. What is the acceleration of the jet?
Answer:
1.78 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{80000}{45000} = \frac{80}{45} \\ = 1.77777...[/tex]
We have the final answer as
1.78 m/s²Hope this helps you

what type of carbohydrates provide the body with a sustained release of energy?
Answer:
Fiber-rich, complex carbs
Complex carbs with fiber take much longer to digest than simple carbs. This helps to maintain stable blood sugar levels because sugar enters the bloodstream gradually . Complex carbohydrates provide sustained energy and help you feel fuller for longer because they are digested more slowly.
Which form of carbohydrates can your body use for energy?Glucose, also known as blood sugar, is the primary energy source for your body's cells, tissues, and organs. Glucose can be used right away or stored for later use in the liver and muscles.Carbohydrates are the body's preferred fuel source because they can be quickly converted to glucose. A light carbohydrate snack right before exercise is a good idea for quick energy. Eat protein with carbs to slow the rate at which your body absorbs them for longer-lasting energy.Fat is the most concentrated source of energy in the body, providing more than twice the potential energy of carbohydrate or protein (9 calories per gram versus 4 calories each per gram).To learn more about : Glucose

how does a phenol red-containing solution look if co2 level is low?
Answer:
The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.
Explanation:
is this correct
A phenol red-containing solution with low CO2 level will appear red.
Phenol red is a substance that serves as an indicator. It changes in colouration in response to the acidity or alkalinity of solutions.
In acidic solutions, phenol red turns yellow while the colour is red in basic solution.
Solutions with high CO2 levels are acidic while those with little to no CO2 concentrations are basic.
Thus, in a low CO2 solution, phenol red will turn red and the solution will generally appear red.

Answer: 1. (0.5 to 1)
2. (Fluorine)
3. (KNO3
4. (Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.)
5. (Fe and S have a covalent bond, and S and O have covalent bonds, too.)
Explanation:
Ye, have great day.
The periodic table is an arrangement of elements according to their periodic properties.
Polar covalent bonds are those compounds in which unsymmetrical electron distribution in bonds leads to polarity in the molecule. Examples of such compounds include; HCl, CHCl3, etc. A polar covalent bond occurs when the electronegativity differences between atoms lies within the range of 0.5 to 1.
Since electronegativity increases across the period and we also know that highly electropositive metals(having very low electronegativity) and highly electronegative nonmetals(having high electronegativity) form a strong ionic bond, it follows that fluorine (F) and cesium (Cs) will form a strong ionic bond.
A poly atomic ion is an ion that contains more than one atom. Given the options listed NH4^+ is an example of a polyatomic ion.
The difference between polar and nonpolar covalent bonds is that polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.
In FeSO4, Fe and S have an ionic bond, while S and O have covalent bonds.

Answer:
X has 9 Electrons, 9 Protons and 10 Neutrons
X is Fluorine
Explanation:
19 in X is Nucleon number
So, if you minus 19 by 9 down there (which is proton number) you'll get 10 (Neutron number).
Now, Proton = Electron. That's why Electron is 9 too. I figured that X is Fluorine bcuz it has 9 Electrons. If you venture around in the periodic table, fluorine is the ninth element innit.

when the orbitals or energy levels of an atom are full, it is considered to be stable. which atom in the ground state has a stable electron configuration?
Answer:
Noble gases, atoms which have complete filled outer orbits.
Explanation:
SInce, you have given no options elements like Neon, Helium,etc
Noble elements are the atoms which have stable electronic configuration in the ground state.
What is electronic configuration?
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

What kind of feature results from the convergence of two oceanic plates?
Answer: When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.
