Answer:

m = 0.5

Explanation:

Given that,

The length of the blade of scissors = 5 cm

The length of the handle = 2.5 cm

Here, effort arm is 2.5 cm and load arm is 5 cm. The mechanical advantage is the ratio of effort arm to the load arm as follows :

[tex]m=\dfrac{2.5}{5}\\\\m=0.5[/tex]

So, the ideal mechanical advantage of a pair of scissors is 0.5.

Convection

Explanation:

Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.

Answer:

what is the question

Explanation:

Answer:

Cold water slows down dissolving

Cold water slows down dissolving. Hence, option (A) is correct.

The basic relationship between solubility and temperature is as follows: A solid will dissolve more readily at higher temperatures.

Likewise, a solid element dissolves more slowly at lower temperatures. This is all due to the solvent becoming more and more excited by the heat, making it easier for it to split or break apart entirely.

for while in gases The solubility of gases decreases more rapidly as temperature rises. A gas is more soluble in water when the temperature is lower.

Henry's law, which states that the gas becomes more soluble as the pressure above the liquid solution increases, summarizes another characteristic of gas solutes.

#SPJ2

Explanation:

It is given that,

Delfino is pushing  the box with a force of 10 N to the left. Aleida is pushing the box with a force of 15 N to the right.

Aleida is exerting more force. He is the more stronger individual.

Net force is given by :

F = -10+15

F = 5 N

So, the net force is 5 N and it is in right direction.

Answer:

a) letting in-flowing and/or out-flowing tide flow through turbines in a dam.

Explanation:

Tidal power makes use of the energy from the tidal force and wave action in order to generate electricity. it is a predictable source of energy.

Tidal Barrages

The system allows tides to enter, seawater flows via the dam and is trapped into the basin when the tides subside and system’s gates close.

When the tides start to move out, the gates in the dam are opened up this consist of turbines and water begins to flow out, hitting the turbines this eventually turn to produce energy.

Power is produced when the tidal range, which is the difference between low and high tide, has to be more than 5 meters.

Answer:

Vertical velocity = 8.28 m/s

Horizontal velocity = 28.3 m/s

__________________________________________________________

We are Given:

Initial velocity of the ball = 40 m/s

Angle of elevation of the ball = 45°

Time interval = 2 seconds

__________________________________________________________

Vertical and Horizontal Components:

Vertical Component:

The vertical component of the ball can also be written as:

40*Sin(45°)

40*(1/√2)                                                          [since Sin(45°) = 1/√2]

40/√2 m/s

Horizontal Component:

The horizontal component of the ball can also be written as:

40*Cos(45°)

40*(1/√2)                                               [Since Cos(45°) = 1/√2]

40/√2 m/s

__________________________________________________________

Speed of the Ball after 2 seconds:

Horizontal Velocity:

Since the horizontal velocity is not affected by any force during the flight, the horizontal velocity after 2 seconds will also be 40/√2 m/s

Since √2 = 1.41:

Horizontal velocity = 28.3 m/s

Vertical Velocity:

v = u + at                            [First equation of motion]

v = 40/√2 + (-10)(2)          

[g is negative because it is acting against the direction of motion]

v = 40/√2 - 20

v = [tex]\frac{40-20\sqrt{2} }{\sqrt{2} }[/tex]                          [taking the LCM]

v = 8.28 m/s                    [√2 = 1.41]

Answer:

Answer. The big five factors of poverty (as a social problem) include: ignorance, disease, apathy, dishonesty and dependency. These, in turn, contribute to secondary factors such as lack of markets, poor infrastructure, poorleadership, bad governance, under-employment, lack of skills, lack of capital, and others.

Answer:

If a zero is found between important digits, it is important. Zeros are also used as (not salient) holders to the left of digits if the number is in fact a decimal. Example from www.rpi.edu: , a mass of 42 g has two significant digits. Expressed in kilograms, the mass of 0.042kg should still have two significant digits.

Answer:

Factories contribute to air and water pollution.

Explanation:

We are given:

Mass of the Paint bucket (with paint) = 7000 grams

Mass of the paint bucket (without paint) = 500 grams

Volume of Paint in the Bucket = 5000 cm³

Mass of Paint in the Bucket:

To get the mass of the paint in the bucket, we will subtract the mass of the bucket from the mass of the paint bucket (with paint)

Mass of Paint = Mass of Paint bucket (with paint) - Mass of the paint Bucket (without paint)

Mass of Paint = 7000 - 500

Mass of Paint = 6500 grams

Density of the Paint:

We know that density = Mass / Volume

Density of Paint  = Mass of Paint / Volume occupied by Paint

Density of Paint = 6500/5000

Density of Paint = 1.3 grams / cm³

Answer:

63J

Explanation:

The question tells us that they both have a kinetic energy of 126 J. What we are required to get is the rotation kinetic energy of the ring

Total kinetic energy =

1/2mv² + 1/2IW²

For ring,

I = mr²

And v = Rw for pure rolling

The total kinetic energy

= 1/2mr² + 1/2mv²

= 126J

126/2

= 63J

The rotational kinetic energy of the ring is therefore 63J.

Answer:

The answer is below

Explanation:

a) Given that the modulus of elasticity (E) = 317 GPa, to find the modulus of elasticity (in GPa) for the nonporous material ([tex]E_o[/tex]), we use the formula:

[tex]E_0=\frac{E}{1-1.9P+0.9P^2}\\\\where\ P=4.7\%=0.047,hence:\\\\ E_0=\frac{317}{1-1.9(0.047)+0.9(0.047)^2}\\\\E_0=347.3\ GPa[/tex]

b) If the porosity P = 11.1%, then the modulus of elasticity is:

[tex]E=E_0(1-1.9P+0.9P^2)=347.3(1-1.9(0.111)+0.9(0.111)^2)=278\ GPa[/tex]
