Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
What is the mass of acetic acid, in measured grams, in 185 mL of vinegar?
The mass of acetic acid would be 9.435 grams, in 185 mL of vinegar if Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
Generally, the density of any substance is expressed by the greek symbol ρ. The density is the reciprocal of the specific volume of any substance.
.
By using the above formula for density
ρ = mass / volume
As given in the problem Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
The total mass of the vinegar
mass= ρ×volume
=1.02×185
=188.7
As given Vinegar contains 5.00% acetic acid (by mass)
the mass of acetic acid = 5×188.7/100
=9.435 gram
Thus, the mass of acetic acid comes out to be 9.435 grams

What are one of the ways the atmosphere recycle gases through interactions with the biosphere?
Through the usage of nitrogen and release oxygen into the atmosphere from plants.
Though the process photosynthesis
O Through available sunlight and release oxygen into the atmosphere.
The mineral content in the ground that plants rely on and release carbon dioxide into the atmosphere.
Answer:
Though the process photosynthesis
Explanation:
One of the important ways by which the atmosphere recycle gases through interactions with the the biosphere is by photosynthesis.
The biosphere is the living component on the earth. The atmosphere is the gaseous envelope round the earth.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water in the presence of sunlight to produce glucose and oxygen gas. This way, atmospheric carbon dioxide is exchanged for oxygen gas.This way, there is a sustained interaction between the atmosphere and biosphere.
Answer:
B. Through the process photosynthesis

Calculate the net acceleration acting on a 40 kg box being pushed across a horizontal floor. There is a 400 N normal force, a 195 N applied force, and a 55 N force of friction resisting any sliding motion. Assume g = 10 m/s ^ 2
Answer:
Net acceleration = 3.5m/s²
Explanation:
Given the following data;
Mass, m = 40kg
Normal force, Fn = 400N
Applied force, Fapp = 195N
Force of friction, Ff = 55N
Mathematically, the net force is given by the formula;
[tex] F_{net} = F_{app} - F_{f}[/tex]
Substituting into the equation, we have;
[tex] F_{net} = 195 - 55 [/tex]
[tex] F_{net} = 140 [/tex]
To find the acceleration;
[tex] F_{net} = ma[/tex]
Making acceleration "a" the subject of formula;
[tex]a = \frac {F_{net}}{m} [/tex]
[tex]a = \frac {140}{40} [/tex]
Net acceleration, a = 3.5m/s²

Water is falling from height of 84 m. If half of the energy of water is converted into heat, the increase in the temperature of the water at the bottom is:
Answer:
what are the options??? to choose the answer from?
Explanation:
Answer:
so its 0.098*C
Explanation:
Let m gram be the mass of water.
Then potential energy of water is:
P.E.=mgh
=m×980×8400
Since potential energy is converted to kinetic energy
P.E.=K.E.
K.E.=m×980×8400
Half of kinetic energy is converted into heat.
Then heat energy:
Heat energy=

×m×980×8400
Convert joule into calories
heat=

But heat is:
Heat=msΔT
∴msΔT=m×0.098
m×1×ΔT=m×0.098
ΔT=0.098C
Rise in temperature of water is =0.098

Which diagram represents a closed circuit with the least resistance?
Answer:Circuit B is the answer
Explanation:
The diagram B represents a closed circuit with the least resistance. Hence, option (C) is correct.
What is electrical circuit?Electric current travels along a circuit to be transmitted. A battery or generator, a device that provides energy to the charged particles that make up the current, a device that uses current, such as a lamp, an electric motor, or a computer, and the connecting wires or transmission lines make up an electric circuit.
Ohm's law and Kirchhoff's rules are two fundamental laws that quantitatively define how electric circuits function.
In diagram A, there has two external resistance.
In diagram B, there has no external resistance.
In diagram C, there has two external resistance.
In diagram D, there has three external resistance.
Hence, the diagram B represents a closed circuit with the least resistance.

A limousine driver notices a stop sign while traveling 55 km/h. What
is the acceleration (in m/s) of the limousine if it comes to a complete
stop in 4.3 52
Interpret the sign of the acceleration - what does it mean?
Answer:
a= -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.
Explanation:
The formula for acceleration is :
a= change in velocity / time
[tex]a=v_f-v_i/t\\[/tex]
where;
[tex]v_f=0km/h\\\\v_i=55km/h\\\\t=4.352s[/tex]
a= 0-55 /4.352 = -55/4.352 = -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.

The symbol used for magnetic field is: Q B F θ
Answer:
B
Explanation:
The symbol of the magnetic field is given as B.
The magnetic field is a force field.
It is a region of space where the action of the magnetic force is felt. The magnetic force is expressed as a non-contact force. One expression of this field is the geomagnetic field which covers the earth. The magnetic field can be produced by the action of the electric field.A 2300 kg sailboat is moving west at 5.5 m/s when an eastward wind
applies an average force of 950 N to is sail for 11.5 s. What is the speed
and direction of the boat after this force?
The boat is initially at equilibrium since it seems to start off at a constant speed of 5.5 m/s. If the wind applies a force of 950 N, then it is applying an acceleration a of
950 N = (2300 kg) a
a = (950 N) / (2300 kg)
a ≈ 0.413 m/s²
Take east to be positive and west to be negative, so that the boat has an initial velocity of -5.5 m/s. Then after 11.5 s, the boat will attain a velocity of
v = -5.5 m/s + a (11.5 s)
v = -0.75 m/s
which means the wind slows the boat down to a velocity of 0.75 m/s westward.
How much tension must a rope withstand if it is used to accelerate a 960 kg car horizontally along a frictionless track at 1.20 m/s²?
Answer:
The tension of the rope is 1152 N
Explanation:
Force
Newton's second law states that the acceleration of an object is directly proportional to the net force and inversely related to its mass.
The law can be written as:
F = m.a
The rope must apply a force F to accelerate the car of m=960 Kg at [tex]a=1.2~ m/s^2[/tex]. Given the track is frictionless, all the force applied produces acceleration, thus:
[tex]F = 960~Kg\cdot 1.2~ m/s^2[/tex]
F = 1152 N
The tension of the rope is 1152 N
Determine the launch speed of a horizontally launched cannonball that lands 26.3
meters from the base of a 19.3 meter high cliff.
Answer:
The cannon has an initial speed of 13.25 m/s.
Explanation:
The launched cannonball is an example of a projectile. Thus, its launch speed can be determined by the application of the formula;
R = u[tex]\sqrt{\frac{2H}{g} }[/tex]
Where: R is the range of the projectile, u is its initial speed, H is the height of the cliff and g is the gravitaty.
R = 26.3 m, H = 19.3 m, g = 9.8 m/[tex]s^{2}[/tex].
So that:
26.3 = u[tex]\sqrt{\frac{2*19.3}{9.8} }[/tex]
[tex](26.3)^{2}[/tex] = [tex]u^{2}[/tex] x [tex]\frac{38.6}{9.8}[/tex]
691.69 = [tex]u^{2}[/tex] x [tex]\frac{38.6}{9.8}[/tex]
[tex]u^{2}[/tex] = [tex]\frac{691.69*9.8}{38.6}[/tex]
= [tex]\frac{6778.562}{38.6}[/tex]
[tex]u^{2}[/tex] = 175.6104
⇒ u = [tex]\sqrt{175.6104}[/tex]
= 13.2518
u = 13.25 m/s
The initial speed of the cannon is 13.25 m/s.
1. An object accelerates 5.0 m/s when a force of 20.0 newtons is applied to it.
What is the mass of the object?
2. An object accelerates 2.0 m/s when a force of 12.0 newtons is applied to it.
What is the mass of the object?
3.An object accelerates 16.3 m/s when a force of 4.6 newtons is applied to it.
What is the mass of the object?
Answer:
1. mass = 4
2. mass = 6
3. mass = 0.28
Explanation:
All these questions require the equation:
F=ma
Where F is force, m is mass and a is accleration. If we do some algebra, we can modify this equation to find mass by dividing both sides by a.
[tex]F=ma --> \frac{F}{a} =\frac{ma}{a} --> \frac{F}{a} = m[/tex]
The a on the left side cancels out and leaves us with [tex]\frac{F}{a}=m[/tex]. Now we can plug in the numbers given to find the mass.
1.[tex]\frac{F}{a} =m-->\frac{20.0}{5.0}=m-->m=4[/tex]
2.[tex]\frac{F}{a} =m -->\frac{12.0}{2.0} =m -->m=6[/tex]
3.[tex]\frac{F}{a}=m--> \frac{4.6}{16.3}=m--> m=0.28[/tex]
So the answers are m=4, m=6, and m=0.28.
