Answer:
0.1 mm
Explanation:
60 sheets = 6 mm
We want 1 sheet so we divide both sides by 60 :
1 sheet = 6/60 mm
1 sheet = 1/10 mm
1 sheet is 0.1 mm

Water is added to a measuring cylinder containing 100 cm3 of liquid paraffin. (the density of paraffin is 0.80 g/ cm3 and that of the water is 1.0 g / cm3 .) as the water is added, the level of the paraffin rises to 150 cm3 . the paraffin and water do not mix. what finally is the total mass of liquid in the measuring cylinder?
The total of the liquid in the measuring cylinder given the data from the question is 130 g
What is density?The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
How to determine the mass of paraffin Density of paraffin = 0.80 g/cm³Volume of paraffin = 100 cm³Mass of paraffin =?Mass = Density × Volume
Mass of paraffin = 0.8 × 100
Mass of paraffin = 80 g
How to determine the mass of water Density of water = 1 g/cm³Volume of paraffin = 100 cm³Volume of paraffin + water = 150 cm³Volume of water = 150 – 100 = 50 cm³Mass of water =?Mass = Density × Volume
Mass of water = 1 × 50
Mass of water = 50 g
How to determine the mass of the mixture Mass of water = 50 gMass of paraffin = 80 gMass of mixture =?Mass of mixture = Mass of paraffin + Mass of water
Mass of mixture = 80 + 50

A 84-kg man stands on a bathroom scale inside an elevator. the scale measures in units of newtons. (a) the elevator accelerates upward from rest at a rate of 1.20 m/s2 for 1.50 s. what does the scale read during this 1.50 s interval
Answer:
94 kg
Explanation:
The mass registered by the scale is based on the assumption that the force applied is due entirely to gravity. If the force is greater, then the indicated mass will be greater.
__
how many g'sAs a fraction of the acceleration of gravity, the elevator's acceleration is ...
(1.2 m/s²)/(9.8 m/s²) ≈ 6/49
net forceThe force required to produce a given acceleration is found by the formula ...
F = ma . . . . . . . force on mass m to produce acceleration 'a'
When the man is stationary on the scale, the upward force it supplies is balanced by the downward force on the man due to gravity. The force and the mass are proportional, and the constant of proportionality (the acceleration due to gravity) is used to calibrate the scale. More force is thus translated to a higher mass reading.
Since the man's net acceleration is upward at the rate of 6/49×g, the total force applied by the scale is (1 +6/49) = 55/49 times as great as when the man is stationary. This greater force gets translated to a greater mass reading.
The force is equivalent to what would be required to support a stationary man with a mass of ...
(84 kg)(55/49) = 94 2/7 kg
The scale would read about 94 kg during the upward acceleration period.
A conducting sphere with radius R carries total charge Q. What is the magnitude of the electric field at distances R/2 and 2R from the center of the sphere
Hello!
Distance of R/2:
Since a conducting sphere is referenced in this situation, all of its charge will be distributed along its SURFACE. Therefore, there is NO enclosed at a distance of R/2 from the center.
Using Gauss's Law:
[tex]\oint E \cdot dA = E\cdot A = \frac{Q_{encl}}{\epsilon_0}[/tex]
E = Electric field strength (N/C)
A = Area of Gaussian surface (m²)
Q = Enclosed charge (C)
ε₀ = Permittivity of free space C²/Nm²)
If the enclosed charge is 0, then:
[tex]E \cdot A = \frac{0}{\epsilon_0}\\\\\boxed{E = 0 \frac{N}{C}}[/tex]
Distance of '2R':
We can once again use Gauss's Law to solve. This time, however, a surface of radius '2R' encloses ALL of the charge of the sphere.
[tex]E \cdot A = \frac{Q_{encl}}{\epsilon_0}[/tex]
'A' is equivalent to the surface area of a sphere of radius '2R', or:
[tex]A = 4\pi (2R)^2\\\\A = 4\pi (4R^2)\\\\A = 16\pi R^2[/tex]
Substituting this expression back into Gauss's Law:
[tex]E \cdot 16\pi R^2 = \frac{Q}{\epsilon_0}\\\\E = \frac{Q}{16\pi R^2\epsilon_0}[/tex]
To simplify:
[tex]E = \frac{1}{4\pi \epsilon_0 } * \frac{Q}{4R^2}\\[/tex]
OR using k = 1/4πε₀:
[tex]\boxed{E = \frac{kQ}{4R^2}}[/tex]

Two astronauts are taking a spacewalk outside the International Space Station. The first astronaut has a mass of 85.2 kg. The second has a mass of 65.4 kg. Initially, both astronauts have zero velocity relative to each other. Then, the astronauts push against each other, giving the first astronaut a final velocity of 1.2 m/s to the left. If the momentum of the system is conserved, what is the final velocity of the second person?
A. 1.3 m/s to the left
B. 1.6 m/s to the right
C. 1.6 m/s to the left
D. 1.3 m/s to the right
The final velocity of the second person after the collision is determined as 1.6 m/s to the right.
Final velocity of the second person
The final velocity of the second person is determined by applying the principle of conservation of linear momentum.
m1u1 + m2u2 = m1v1 + m2v2
85.2(0) + 65.4(0) = 85.2(-1.2) + 65.4(v2)
0 = -102.24 + 65.4v2
65.4v2 = 102.24

An object whose mass is 0.092 kg is initially at rest and then attains a speed of 75.0 m/s in 0.028 s. What average net force acted on the object during this time interval?
Answer:
F = 246.4 N
Explanation:
Concepts:Newton's Laws Of MotionFirst Law: (Law of Inertia)
Inertia refers to the tendency of an object to resist any change in its state of motion. Inertia is a measure of the objects mass.Second Law:
refers to an object's motion when a net force does not equal zero. Acceleration is directly proportional to the net force and inversely proportional to the object's mass.Third Law: (Action - Reaction)
Whenever one object exerts a force on a second object, the second objects exert an equal but opposite force on the first.Weight:
Force of gravity is the weight of an object and is measured in Newtons.Friction:
Frictional forces always oppose motion. The frictional forces ([tex]F_f[/tex]) is proportional to the coefficient of friction (Ц) and to the normal force [tex](F_n) F_f=uF_n[/tex].The normal force is a contact force which acts perpendicular to the common surface of contact.Now onto the steps:
----------------------------------
F = mΔV ÷ t
F = 0.093 x 75 ÷ 0.028
F = 246.4 N
Therefore, the average net force acted on the object during this time interval is 246.6 Newtons.
