Explanation:
The blade of a metal cutter is shorter than that of the scissors used by tailor.why
Answer:
It depends on the amount of pressure needed to cut your material. Metal is a tougher material to cut though, so the blades must be shorter to create more pressure to break through the metal. Cloth on the other hand is easier to cut through so the blades can be longer in order to cut more in each snip.
sigma F = T-10m but a = 0 in the equation sigma F = ma
Answer:
m = T/10 = (1/10) T
Explanation:
From the question given:
∑F = ma .... (1)
∑F = T – 10m .... (2)
a = 0 m/s²
m =?
Thus, we can obtain m in terms of T as shown below:
From equation (1)
∑F = ma
a = 0 m/s²
∑F = ma = m × 0
∑F = 0
Next, substitute the value of ∑F into equation (2) to obtain m. This is illustrated below:
∑F = T – 10m
∑F = 0
0 = T – 10m
Rearrange
0 + 10m = T
10m = T
Divide both side by 10
m = T/10
m = (1/10) T
Therefore, m is (1/10) T
Anna wanted to see what battery lasts the longest she put each batter into a clock and recorded the time that the clock stopped she use their sale energizer Kroger brand and everybody what is the constant
Answer:
The resistance of the clock circuit.
Explanation:
In electricity, the potential difference or voltage is the drive force. It is known as the electromotive force in a battery or generator. The potential difference is the difference in the higher terminal and the lower terminal of the circuit. The potential difference forces electrons to move in an orderly fashion, from the higher potential to the lower potential; this flowing electrons is what is called the current of the circuit. When the electrons flow, they meet a certain amount of resistance. This resistance is unique to the material of the circuitry, and does not change in a circuit. The value of the resistance of the circuit remains the same, even when the potential difference of the electrical energy source is depleted, and current stops to flow.
give an expression for the mechanical advantage of an inclined plane
Answer:
The mechanical advantage of an inclined plane, equal to the length of the plane divided by the height. The mechanical advantage for a ramp is the ratio of the force applied to the output force. By conservation of energy, the mechanical advantage can be expressed in terms of the distance traveled.

Some vehicles, like _____, have different rules for registration and renewal. A. trailers B. coupes C. sedans D. pickup trucks
Answer:
trailers
Explanation:
Some vehicles, like trailers, have different rules for registration and renewal
What is the registration process for trailers?Before registering a trailer, you will generally need to submit a signed title to verify your ownership. Alternately, you might be able to use a manufacturer’s statement of origin.
You will also need to sign and submit an application for the license and title of the trailer, along with receipts of applicable property taxes. Finally, you will need to pay the registration fees.
Before you make a trip to the DMV, make sure to have two forms of photo ID on hand to verify your identity when you speak with an agent. For example, your driver’s license might serve as the primary form of ID, and a passport could serve as the second.
If you do not have a passport, you could use a military identification card instead. If your only form of photo ID is your driver’s license, be sure to have other forms of identification on hand, such as your birth certificate and the card with your Social Security number.
Hence Some vehicles, like trailers, have different rules for registration and renewal.

5) Make the measurement equal by conversion. 2000 g = 2 kg 14000m = 14 km mm = 160 cm 0.8 m = cm 109 g = kg kg = 5.6 g L = 75 mL 16.5mm = cm
Answer:
1600 mm80 cm0.109 kg0.0056 kg0.075 L1.65 cmExplanation:
The relevant conversion factors are ...
1 m = 100 cm
1 cm = 10 mm
1 kg = 1000 g
1 L = 1000 mL
These are based on the meanings of the SI prefixes:

milli- = 1/1000
kilo- = 1000

A car accelerates uniformly from rest to a speed of 18 m/s in 12 seconds. Find the acceleration of the car over this period.
The correct answer is [tex]1.5 m/ s^{2}[/tex]
Explanation:
In general terms, the acceleration refers to how velocity changes or increases. This is measured in meters per second squared ([tex]m/s^{2}[/tex]) or similar units such as kilometers per hour squared ([tex]km/h^{2}[/tex]). Moreover, to calculate acceleration it is necessary to subtract the initial velocity from the final velocity and then divide this into the time. The formula and operation are shown below:
[tex]a (acceleration) = \frac{v (final velocity) - u (initial velocity)}{t (time)}[/tex]
[tex]a= \frac{18 m/s - 0 m/s}{12 s}[/tex] (Initial velocity is 0 m/s because the car was at rest)
[tex]a = \frac{18 m/s}{ 12 s}[/tex]
[tex]a = 1.5 m/s^{2}[/tex]
According to this, the acceleration of the car was [tex]1.5 m/s^{2}[/tex]

you must design a runway that allows planes to reach a ground speed of 65 m/s before they can take off. If the planes accelerate at 2.5m/s/s, what must the minimum length of the runway be?
Answer:
d = 845 m
Explanation:
This is an exercise in kinematics, specifically accelerated motion, let's use the equation
v² = v₀² + 2 a d
since airplanes start from rest their initial velocity is zero
v² = 2ad
d = v2 / 2a
let's calculate
d = 65² / (2 2.5)
d = 845 m
this is the minimum distance from the track

C: Mass x Velocity
D: Force a 5N Force B 10N Net force of forces A and B 15N
Answer:
option A is correct

acceleration the time rate of change of velocity or speed so
a=Δv/t
Δv=vf-vi
Δv= final speed-initial speed
now a=final speed-initial speed/time

please help! need a answer as quick as possible please. i need help with questions 1 and 2 ! thank you
Answer:
1.)When you arrive from school and you smell cookies baking in the kitchen your brain will tell you that you are hungry and that you should go to the kitchen at that point your sense organs like your nose helps you to detect that something is baking(cookies)and your nervous system (brain)will tell you that you are hungry and it will command/direct your brain to go to the kitchen then for you to eat the cookies and drink the milk the digestive system is going go help you to chew,swallow and digest the food which has been taken and when you also run to the kitchen at the beginning your brain will direct your skeletal and muscular system because the skeletons and muscles work hand in hand,and when you finish your meal the body will circulate some nutrients or minerals from the food or snack taken to other parts of the body for energy.
2.)When you sleep the whole body is asleep except the heart which needs to continue circulating blood around the whole system and sometimes the brain may not rest when you are sleeping it may continue to do it's work that's why some people usually sleep walk or sleep talk,it means the brain is not at rest and still doing some things....Thank you for the question I hope it is very useful to you.
An internal combustion engine has an efficiency of 22.3%. This engine is used to deliver 6.25x 40 J of work to drive the motion of the train. What is the total energy that needs to be put into the engine?
Answer:
Explanation:
efficiency = energy output x 100 / energy input
putting the values
22.3 = 6.25 x 10⁴ x 100 / energy input
energy input = .28 x 10⁶
= 28 x 10⁴ J
energy that needs to be put into the engine = 28 x 10⁴

Subtract 2.5×10^-5 from 8.0×10^-3 with regards to significant numbers.
Answer:
8.0 x 10⁻³
Explanation:
(8.0×10⁻³) - (2.5×10⁻⁵)
= (8.0×10⁻³) - (2.5 × 10⁻² x 10⁻³) (factor out 10⁻³)
= 10⁻³ [ 8 - (2.5 x 10⁻²) ]
= 10⁻³ [ 8 - 0.025 ]
= 10⁻³ [ 7.975 ]
= 7.975 x 10⁻³
however we can observe that both original numbers are expressed to 2 significant figures, hence we must express our answer also in 2 significant figures by rounding 7.975 to 8.0, thereby giving us:
8.0 x 10⁻³
If a force of 2 N applied over an area of 2 cm², calculate the pressure produced.
Answer:
10000 Pa

We know that,
Formula of pressure =
Pressure = Force/Area = 2N/0.0002 [tex]m^2[/tex] = 10000 Pascal
[tex]\boxed{\sf Pressure=\dfrac{Force}{Area}}[/tex]
[tex]\\ \sf\longmapsto Pressure=\dfrac{2}{0.0002}[/tex]
[tex]\\ \sf\longmapsto Pressure=10000Pa[/tex]
