A machine produces a larger force than you exert to operate the machine. How does this input distance of the machine compare to its output distance?

Answer:(B) 25.0 N

Explanation:

This is what makes most since. You are wanting to look at the stress of the first wire. 25 *3 for the amount of balls handing of the string you get 75.0 N which is the max the top wire can hold without breaking! Hope this helps!

Answer:

Acceleration occurs when an object changes its VELOCITY or DIRECTION or both.

Explanation:

Answer:

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. answer velocity or direction.

Explanation:

Divide 200 by 40 to get the rate of speed in seconds

Answer:

≈ 10.23mph

Explanation:

1760yrds in 1 mile

200yrds to miles is:

200/1760 = .1136miles

3600sec in 1 hr

40sec to hours is:

40/3600 = .011111hrs

Now we find her speed in miles per hour:

.1136mi/.01111hrs ≈ 10.23mph

Answer:

Scientists replicate other scientists' experiments to test if the result of the original investigations being tested should become a law, therefore, meaning if it should be generally accepted or discarded.

However, using different conditions than the conditions used in the original investigations is a method employed by scientists usually to:

1. Check if the values, equipment, used by the original investigations can give similar results if the values are lowered or increased and to also test if the result of the original investigations can be the same even if conditions are adjusted.

2. Check the accuracy of some experimental results especially when those original investigations are the first to speak about a new topic/finding. Definitely, other scientists would use different conditions to provide a broad knowledge and a general acceptance.

Galileo's investigation on the moon rejected popular beliefs of the content of the moon paved the way for further investigations by other astronauts. Galileo performed his investigations with equipment centuries back, coupled with the fact that his investigation didn't support an existing belief that paved the way for his investigation to be replicated by other astronauts.

Explanation:

BY CALCULATION USING THE FORMULA S=FD

Answer:

solution

distance travelled : 500km

time taken:4 hour

speed:?

now

speed: distance travelled ÷ time taken

or, 500 ÷ 4

therefor,speed :125km/h

Answer:

The acceleration of the motorbike as it came to a stop was -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Explanation:

From the question,

A motorbike is traveling to the left with a speed of 27.0 m/s.

This is the initial speed, that is, initial speed = 27.0 m/s

Also, from the question,

The rider slams on the brakes and the bike skids 41.5 m, that is, the bike covers a distance of 41.5 m after the rider slams on the brakes.

Distance = 41.5 m

To determine the acceleration of the motorbike as it came to a stop,

Since, the bike came to a stop, then, the final speed is 0 m/s

From one of the equations of motion for linear motion

v² = u² + 2as

Where v is the final speed (velocity)

u is the initial speed (velocity)

a is the acceleration

and s is the distance

From the question

v = 0 m/s

u = 27.0 m/s

s = 41.5 m

Putting these into the equation

v² = u² + 2as

0² = 27.0² + (2×a×41.5)

0 = 729.0 + 83a

83a = -729.0

a = -729.0 / 83

a = -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Answer:

8.8 m/s^2

Answer:

I = 1.4 [amp]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.

Therefore:

V = I*R

where:

V = voltage = 14[V]

I = current [amp]

R = resistance = 10 [ohm]

I = 14/10

I = 1.4 [amp]

Answer:

A barcode reader (or barcode scanner) is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating for optical impulses into electrical signals.

Answer:

2.61 [tex]\frac{m}{s}[/tex]

Explanation:

v= d/t

v = 6m/2.3 s

v=2.61 [tex]\frac{m}{s}[/tex]

Answer:

[tex]\boxed {\tt v\approx2.61 \ m/s}[/tex]

Explanation:

Velocity can be found by dividing the displacement by the time.

[tex]v=\frac{d}{t}[/tex]

The displacement is 6 meters and the time is 2.3 seconds.

[tex]d= 6 \ m\\t= 2.3 \ s[/tex]

Substitute the values into the formula.

[tex]v=\frac{6 \ m}{2.3 \ s}[/tex]

Divide.

[tex]v=2.60869565 \ m/s[/tex]

Let's round to the nearest hundredth. The 8 in the thousandth place tells us to round the 0 to a 1.

[tex]v\approx2.61 \ m/s[/tex]

The velocity of the marble is about 2.61 meters per second.

Answer:

20kph

Explanation:

Since she travels 100kpm in 5 hours and 100 divided by 5 is 20 she would travel 20km in one hour

Mass of two bumper cars, m₁ = m₂ = 125 kg

Initial speed of car X is, u₁ = 10 m/s

Initial speed of car Z is, u₂ = -12 m/s

Final speed of car Z, v₂ = 10 m/s

We need to find the final speed of car X after the collision. Let v₁ is its final speed. Using the conservation of momentum to find it as follows :

[tex]m_1u_1+m_2u_2=m_1v_1+m_2v_2[/tex]

v₁ is the final speed of car X.

[tex]m_1u_1+m_2u_2-m_1v_1=m_2v_2\\\\m_2v_2=m_1u_1+m_2u_2-m_2v_2\\\\m_1v_1=125\times 10+125\times (-12)-125\times 10\\\\v_1=\dfrac{-1500}{125}\\\\v_1=-12\ m/s[/tex]

So, car X will move with a velocity of -12 m/s.
