1.Two materials that can be scratched by an iron mail are ___, ___
2.What is the substance that can be scratched by an iron nail but not a penny?
Please answer
Answer:
1. Two materials that can be scratched by an iron nail are zinc and aluminum
2. A substance that can be scratched by an iron nail but not a penny is;
Nickel
Explanation:
The hardness of a material can be defined as its ability to resist being plastically deformed at a location due to mechanical scratching, abrasion or indentation
The Mohs hardness scale provides a ranking of materials in the order of hardness with a material having a higher Mohs hardness number being able to scratch other materials which have a lower Mohs hardness number
1. From the Mohs scale of hardness, iron which has an harness number of 4.5 can scratch zinc which has an harness number of 2.5, and iron can also scratch aluminum which has an hardness number of 2.5 to 3
2. A penny is made from copper plated material and will have an outer layer hardness of copper which has an hardness number of 3 on the Mohs scale
Therefore, a penny cannot scratch a material mode of nickel which has an hardness number of 4, while iron which has an hardness of 4.5 will scratch a nickel material
(1) Zinc and aluminum can be scratched by an iron nail.
(2) Nickel can be scratched by an iron nail but not a penny.
Hardness and deformation:The hardness of a material is defined as its ability to resist deformation due to mechanical scratching, abrasion, or indentation.
According to the Mohs hardness scale, a material having a higher Mohs hardness number is able to scratch other materials which have a lower Mohs hardness number.
From the Mohs scale of hardness, iron has a hardness number of 4.5, zinc has a hardness number of 2.5, and aluminum which has a hardness number between 2.5 to 3. So, iron can scratch both, Zinc and Aluminium.
A penny is made from copper-plated material copper has a hardness number of 3 on the Mohs scale. Whereas Nickel has a hardness number of 4. Therefore, a penny cannot scratch a material made of Nickel.

When a branch is added to a parallel circuit, the total resistance decreases, so the current in the circuit increases.
What is meant by a parallel circuit ?A parallel circuit is defined as the type of circuit in which the resistors are connected in parallel such that the current flowing through each of them is different.
Here,
The given circuit is connected in parallel combination of resistors. The current has different pathways to flow through. The voltage applied across each resistors will be the same.
Consider a parallel resistance circuit having a combination of n number of resistors with resistance R. The effective resistance of the parallel circuit can be given as,
1/Reff = 1/R₁ + 1/R₂ + 1/R₃ +....1/Rₙ
Since, the resistance is same on all resistors, we can write,
Reff = R/n
So, when adding a branch, the number of resistors, n increases. As a result, the effective resistance of the circuit decreases.
According to Ohm's law, as the resistance of a circuit decreases, the flow of current through the circuit increases.
Hence,
When a branch is added to a parallel circuit, the total resistance decreases, so the current in the circuit increases.

A bus as speed of 20m/s begin to slow at constant acceleration of 8.00m/s2 along a straight line find the average speed for the 5al.S interval
Answer:
the final velocity of the bus is -20 m/s.
Explanation:
Given;
initial velocity of the bus, u = 20 m/s
deceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
The final velocity of the bus is calculated as;
v = u + at
v = 20 + (-8 x 5)
v = 20 - 40
v = -20 m/s.
Therefore, the final velocity of the bus is -20 m/s.

A roller skater of 47kg moving with a velocity of 12 m/s to the east picks up a bag of 6.0 kg. What is the final velocity of the person traveling with the basket? show your work HINT: Use the law of conservation of momentum in the perfectly inelastic collision m1v1i + m2v2i = (m1+m2) vf
plz guys i have exam now answer her quikly
Answer:
v_f = 10.85 m/s
Explanation:
We will apply the law of conservation of momentum here:
[tex]m_{1}v_{1i} + m_{2}v_{2i} = m_{1}v_{1f}+m_{2}v_{2f}\\[/tex]
where,
m₁ = mass of roller skater = 47 kg
m₂ = mass of bag = 6 kg
v_1i = initial speed of roller skater = 12 m/s
v_2i = initial speed of the bag = 0 m/s
v_1f = final speed of the roller skater = ?
v_2f = final speed of the bag = ?
Both the bag and the skater will have same speed at the end because kater is carrying the bag:
v_1f = v_2f = v_f
Therefore, the equation will become:
[tex](47\ kg)(12\ m/s)+(6\ kg)(0\ m/s)=(47\ kg)(v_{f})+(5\ kg)(v_{f})\\564\ N.s = (47\ kg+5\ kg)(v_{f})\\v_{f} = \frac{564\ N.s}{52\ kg}\\[/tex]
v_f = 10.85 m/s

Write a short 6 sentence summary answering this: How did Newton alter the Solar System model proposed by Kepler and what other contributions did he make to Astronomy?
Thank you all for helping me! you saved my grade by a lot!
Answer:
If Kepler’s laws define the motion of the planets, Newton’s laws define motion. Thinking on Kepler’s laws, Newton realized that all motion, whether it was the orbit of the Moon around the Earth or an apple falling from a tree, followed the same basic principles. “To the same natural effects,” he wrote, “we must, as far as possible, assign the same causes.” Previous Aristotelian thinking, physicist Stephen Hawking has written, assigned different causes to different types of motion. By unifying all motion, Newton shifted the scientific perspective to a search for large, unifying patterns in nature. Newton outlined his laws in Philosophiae Naturalis Principia Mathematica (“Mathematical Principles of Natural Philosophy,”) published in 1687.
Law I. Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed theron.
In essence, a moving object won’t change speed or direction, nor will a still object start moving, unless some outside force acts on it. The law is regularly summed up in one word: inertia.
Law II. The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.
Newton’s second law is most recognizable in its mathematical form, the iconic equation: F=ma. The strength of the force (F) is defined by how much it changes the motion (acceleration, a) of an object with some mass (m).
Law III. To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.
As Newton himself described: “If you press a stone with your finger, the finger is also pressed by the stone.”

The smallest bird is the Cuban bee hummingbird, which has a mass of only 1.7 g. If this bird did 8.8 10 –4J of work by exerting an upward force of 3.4 10 –4 N, how far did it fly?
Answer:
The distance the bird flew is approximately 2.59 meters
Explanation:
We list out the parameters in the question, and the required measurement as follows;
The mass of the Cuban bee hummingbird, m = 1.7 g = 0.0017 kg
The amount of work the bird does, W = 8.8 × 10⁻⁴ J
The amount of upward force the bird exerts, F = 3.4 × 10⁻⁴ N
Let 'd' represent the distance flown by the bird
(The downward force, [tex]F_g[/tex] = The weight of the bird, W
W = The mass of the bird, m × The acceleration due to gravity, g
The acceleration due to gravity, g ≈ 9.81 × 10 m/s²
∴ [tex]F_g[/tex] ≈ 0.0017 kg × 9.81 m/s² = 0.016677 N > F)
Given that the weight of the bird is larger than 'F', we assume that the force exerted by the bird is the net force, [tex]F_{NET}[/tex] = F
Therefore;
Work done, W = Net Force, [tex]F_{NET}[/tex] × Distance, d
∴ W = [tex]F_{NET}[/tex] × d
d = W/[tex]F_{NET}[/tex] = 8.8 × 10⁻⁴ J/(3.4 × 10⁻⁴ N) = 2.58823529 meters
The distance the bird flew, d ≈ 2.59 m.
