Answer:

F = ma or Force = mass x acceleration.

Explanation:

Newtons second law is about the force put onto an object. To find this you would use the formula:

Force is equal to mass times acceleration (F=ma)

Answer : The equation most often associated with Newton's Second Law of Motion is, $a=\frac{F}{m}$

Explanation:

Newton's second law : It is defined as the acceleration of an object is directly proportional to the amount of force applied to it and it is inversely proportional to the mass of an object.

The equation used for Newton's Second Law of Motion is:

$a=\frac{F}{m}$

where,

a = acceleration of an object

F = force applied on object

m = mass of an object

How many liters of 4M solution can be made using 100 grams of lithium bromide

uysha [10]

Molar mass of LiBr (mm )= 86.845 g/mol

Molarity ( M ) = 4 M

Mass of solute ( m ) = 100 g

Volume ( V ) = in liters ?

V = m / mm * M

V = 100 / 86.845 * 4

V = 100 / 347.38

V = 0.2875 L

hope this helps!.

An airplane travels 2100 km at 1000km/hE. It encounters a wind and slows to 800 km/h E for the next 1300 km. What is the average

Deffense [45]

Answer:

The average velocity of the airplane for this trip is 1684.21 km/h

Explanation:

Average velocity is the rate of change of displacement with time. That is,

Average velocity = $\frac{Displacement }{Change in time}$ = Δx / Δt = $\frac{x2 - x1}{t2 - t1}$

Now we will calculate the time taken by the airplane for the first motion before it encounters a wind.

From,

Velocity = $\frac{Distance traveled}{Time taken}$

Time = $\frac{Distance traveled}{Velocity}$

Therefore, Time = $\frac{2100km }{1000km/h}$

Time = 2.1h

This is the time taken before the airplane encounters a wind.

Hence, t1 = 2.1h

Now, For the time taken by the airplane when it encounters a wind

Also from,

Velocity = $\frac{Distance traveled}{Time taken}$

Time = $\frac{Distance traveled}{Velocity}$

Therefore, Time = $\frac{1300km }{800km/h}$

Time = 1.625h

Hence, t2 = 1.625h

Now, to calculate the average velocity

Average velocity = $\frac{x2 - x1}{t2 - t1}$

x1= 2100, x2= 1300, t1= 2.1h and t2= 1.625h

Hence, Average velocity = $\frac{1300 - 2100}{1.625 - 2.1}$

Average velocity = 1684.21 km/h

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction tums them into gaseous products. The cylinder h

erastova [34]

Answer:

The reaction is exothermic

The temperature of the water bath goes up

Explanation:

An exothermic reaction is one in which energy flows out of the reaction system.

In this case, the system is the reaction vessel while the surrounding is the water bath. We see in the question that 300.1J of heat flows out of the system during the reaction. This is heat lost to the surroundings showing that the reaction is exothermic.

As energy is lost to the surroundings, the temperature of the water bath rises accordingly.

Alkynes have what in<br> common with alkenes ?

jonny [76]

Answer:

Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups. Alkanes are identified because the carbon chain has only single bonds. Alkenes have at least one double bond and alkynes have at least one triple bond. The most common alkyne is ethyne, better known as acetylene.
