An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration would be

Answers

Answer 1

Answer:

12.0 m/s²

Explanation:

Newton's second law:

F = ma

Solving for acceleration:

a = F/m

If force is doubled and mass is tripled:

a' = (2F)/(3m)

a' = ⅔ (F/m)

a' = ⅔ (18.0 m/s²)

a' = 12.0 m/s²

Answer 2

The new value of acceleration of object is 12 m/s².

Given data:

The magnitude of acceleration of object is, [tex]a =18 \;\rm m/s^{2}[/tex].

Let F be initial net force and m be the initial mass. Then as per the problem, the new values of each are,

F' = 2F

m' = 3m

Apply the Newton's Second law, which says that the product of mass and acceleration of object given net force. Then,

F = ma

F = m(18)

F/m = 18 .................................................(1)

Now, for new value of net force,

F' = m'a'

2F = (3m) a'

2F/3m = a'

a' =2/3× (18)                                                   (From equation 1)

a' = 12 m/s²

Thus, we can conclude that the new value of acceleration of object is 12 m/s².

In a series circuit, electrons only flow along one path. Given this information, which of the following is an advantage of series circuits?
A.
The voltage is the same everywhere in a series circuit.
B.
Less resistance is produced as more devices are added to the circuit.
C.
Series circuits are simpler than parallel circuits.
D.
If one part of the circuit breaks, the other parts will still be able to operate.

Answers

Answer:

C.  Series circuits are simpler than parallel circuits.

Explanation:

In series circuit, all the components are connected in single path of current flow. If one part of the circuit breaks, the whole thing would break and none of the other parts would work. The voltage is not the same everywhere. It is different across each component. In series circuit, net resistance is more as resistance of all the components connected in series are added up. So, the only advantage of a series circuit is that is simpler than the parallel circuits.

Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn

Answers

Answer:

Producing 300 L of ethanol from potatoes

Explanation:

From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.

1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.

1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material

About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.

In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.

what is mass times acceleration?

Answers

Answer:

Force

Explanation:

The mass of an object is the quantity of matter it contains. It is measured in kilograms.

Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].

When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.

i.e     F = m × a

where F is the force, m is the mass of the object and a its acceleration.

The two major classes of force are; contact force and field force.

Explanation:

The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.

What is the spring scale?

A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."

One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.

if 34.7 g of O2 reacts with iron to form 79.34 g of iron oxide, how much iron was used in the reaction?

A.
19.84 g

B.
44.64 g

C.
104.1 g

D.
114.04 g

Answers

Answer: B. 44.64 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g

Mass of product = mass of iron oxide = 79.34 g

As Mass of reactants = Mass of product

mass of iron + 34.7 g = 79.34 g

mass of iron = 44.64 g

Thus 44.64 g of iron was used in the reaction

What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?​

Answers

KE = 0.5 x mv^2

Kinetic energy equals 1/2 times mass times velocity squared.

Mass = 15kg

Velocity = 3m/s

Plug it into the formula.

KE = 0.5 x 15(3^2)

KE = 0.5 x 15(9)

Multiply the mass and velocity squared.

KE = 0.5 x 135

Then, multiply the result by 1/2 or 0.5

KE = 67.5

The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.

Answer:

67.5 J

Explanation:

Kinetic energy can be found using the following formula.

[tex]KE=\frac{1}{2}mv^2[/tex]

where m is the mass in kilograms and v is the velocity in m/s.

We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v

[tex]KE=\frac{1}{2}*15*3^2[/tex]

Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.

[tex]KE=\frac{1}{2} *15*9[/tex]

Multiply 15 and 9.

[tex]KE=\frac{1}{2} *135[/tex]

Multiply 1/2 and 135

[tex]KE=67.5[/tex]

Add appropriate units. Kinetic energy uses Joules or J as the units.

[tex]KE= 67.5 Joules[/tex]

The kinetic energy of the bike is 67.5 Joules

Which term is defined as the force applied to the object divided by the mass of the object?

speed

mass
acceleration

Answers

Answer:

acceleration

Explanation:

From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.  

Now, the second Newton's law says "F = m . a ", where a is acceleration.

If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:

a = F / m

acceleration = force / mass

Explanation:

Density is expressed in units of mass per volume, such as g/mL or kg/m3. Because the density of a substance does not depend on the amount of substance present, density is an “intensive property”. To measure the density of a sample of material, both the mass and volume of the sample must be determined.
