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

Answer:

It lasted two hours or 120 minutes, it would be smart to say that he was riding up it during the interval 20-60min and riding down it during the interval 60-80min. This is an assumption made because of his speed, when going up a hill our speed is slower while when riding down it, you gain a lot of speed.

Answer:

Difference

Explanation:

The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.

If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.

Answer:

1. 100N 2. 50N 3. 50N

Explanation:

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

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.

Answer:

D. Number of components

Explanation: hope this helps :)

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

Answer:

The efficiency of the machine is 40 %.

Explanation:

We have,

Output work by the machine is 4 joules and the input work is 10 joules.

It is required to find the efficiency of a machine. The efficiency of a machine is given by the ratio of output work to the input work. It is given as :

[tex]\eta=\dfrac{4}{10}\times 100\\\\\eta=40\%[/tex]

So, the efficiency of the machine is 40 %.

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

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.

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.

Visible Spectrum is the type of electromagnetic wave with a wave length between 700 and 400 billionths of a meter.

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:

Given that the

Mass M = 5 kg

Height h = 0.3 m

Let us take acceleration due to gravity g = 9.81 m/s^2

Substitute all the parameters into the formula above

P.E = 5 × 9.81 × 0.3

P.E = 14.715 J

P.E = 14.7 J approximately

Answer:

D. Density is independent of the

amount of the sample.

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.
