Answer:
Hey mate.....
Explanation:
This is ur answer.....
Sound travels faster in steel than in water. Similarly, sound travels faster in water than in air. This is because in solids, the distances between the molecules are closer and thus the atoms are more densely packed than in gases and liquids

A 3.00 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 124 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 11.9 m/s, while the spring is initially unstrained. What is the amplitude of the resulting simple harmonic motion
Answers
Answer:
[tex]A=0.185m[/tex]
Explanation:
From the question we are told that
Mass of Block [tex]M=3*10^-2kg[/tex]
Spring constant [tex]\mu=124 N/m[/tex]
Initial Speed [tex]V_1=11.9m/s[/tex]
Generally the equation for Kinetic Energy is mathematically given by
[tex]K.E=1/2 mv^2[/tex]
Therefore
[tex]K.E_1=1/2*0.03*11.9^2[/tex]
[tex]K.E_1=2.12J[/tex]
Where
[tex]Initial K.E_1=Final K.E[/tex]
Generally the equation for Final Energy stored is mathematically given by
[tex]K.E_2=0.5\mu a^2[/tex]
Therefore
[tex]K.E_1=K.E_2[/tex]
[tex]0.5\mu A^2=2.12J[/tex]
[tex]A=\sqrt{\frac{2.12}{0.5*124}}[/tex]
[tex]A=0.185m[/tex]
Therefore the amplitude of the resulting simple harmonic motion is
[tex]A=0.185m[/tex]

C. The higher temperature increases the forward reaction rate, and
the higher pressure increases the reaction rate.
D. The higher temperature decreases the reaction rate, but it also
favors the forward reaction.
Answers
Answer: B
Explanation: The higher temperature increases the reaction rate but also favors the reverse read on.
The higher temperature increases the reaction rate, but it also favors the reverse read on. So, option B.
What is meant by rate of a reaction ?The pace at which the products are created from the reactants in a chemical reaction is referred to as the rate of reaction.
Here,
Generally, reactions progress more quickly as the temperature rises.
The average kinetic energy of the reactant molecules will rise with a rise in temperature. The number of molecules having threshold energy rises, increasing the quantity of efficient collisions that actually occur.
Therefore, as the temperature of the reaction is increased, the rate of the reaction increases. But also favors the reverse reaction.
Hence,
The higher temperature increases the reaction rate, but it also favors the reverse read on.

Around the turn of the twentieth century, inventor Robert Shuman was engineering products that used energy directly from the Sun to power motors and farms. He stated that coal and oil would eventually run out and that humans needed to learn how to use the more-abundant energy resource of the Sun. During which stage of technological design did Shuman identify that using oil and coal would be a problem? first second third fourth

Answer: First stage
Explanation:
The four stages of technological design include:
• identifying a problem.
• Designing a solution.
• Implement, build, and test the design.
• Determine if solution met the need.

D. (- 6.94x10-12 C) and (- 6.94x10-12 C)
Answers
Answer:
A: -2.6 × 10^(-6) C and 2.6 × 10^(-6) C
Explanation:
According to coulombs law, the formula for the force between 2 charged particles is;
F = kq1•q2/r²
Where;
F is Force = |1N|
q1 and q2 are the charges of both particles
k is coulombs constant = 9 × 10^(9) N.m²/C²
r is distance between particles = 0.25
Now, the force |1N| means -1 or +1
Thus;
-1 = 9 × 10^(9) × q1•q2/(0.25)²
Or
1 = 9 × 10^(9) × q1•q2/(0.25)²
Thus;
q1•q2 = -6.94 × 10^(-12)
Or q1•q2 = 6.94 × 10^(-12)
Now, we are told that the magnitude of both charges are the same.
Thus;
q² = 6.94 × 10^(-12)
q = √(6.94 × 10^(-12))
q = 2.6 × 10^(-6) C
Since from earlier, we saw that;
q1•q2 = -6.94 × 10^(-12)
Or q1•q2 = 6.94 × 10^(-12)
Thus means that one of the charges will be negative while the other will be positive.
Thus, the charges are;
-2.6 × 10^(-6) C and 2.6 × 10^(-6) C
Four 29-ohm resistors are connected in series to an ideal 10-volt battery. What is the equivalent resistance of the circuit?
Answers
Answer:
Equivalent resistance of the circuit is 116 ohm.
Explanation:
Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so
→ Equivalent resistance = R_1 + R_2 + R_3 + R_4
→ Equivalent resistance = (29 + 29 + 29 + 29) ohm
→ Equivalent resistance = 116 ohmA grocery shopper tosses a(n) 8.6 kg bag of rice into a stationary 18.1 kg grocery cart. The bag hits the cart with a horizontal speed of 5.2 m/s toward the front of the cart. What is the final speed of the cart and bag

Baseball from pitch to hits
Answers
The correct answer to this open question is the following.
Unfortunately, you did not attach the article or the text. You also forgot to attach the options for the question.
However, trying to help you we did some deep research and can comment on the following.
The statement that describes the central idea of the text is "Baseball can be explained and improved by collecting data and studying the natural laws at play in the sport."
You are referring to the article written by Stephen Ornes, of August 21, 2013, for Science News for Students.
The author refers to the idea that baseball and physics are related and can be understood through the "eyes" of science. Statistics bring interesting data to help understand the game.
And this idea is correct because today, baseball coaches and other sports coaches as is the case of football, use a series of statistics and data to better hire talent for their respective teams, as well as to better create plans and game strategies derived from the results and interpretation of data.
Can you tell from an FBD if an object is moving or not? Explain your response.
Answers
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.

What would be the force required to accelerate an object that weighs 35 N up at a rate of .60 m/s^2?
Answers

Explanation:
Given
Force required to accelerate the object at the rate of [tex]0.6\ m/s^2[/tex]
The weight of the object is [tex]W=35\ N[/tex]
Mass of the object can be identified by dividing the weight by acceleration due to gravity
[tex]\Rightarrow m=\dfrac{W}{g}\\\\\Rightarrow m=\dfrac{35}{9.8}\\\\\Rightarrow m=3.57\ kg[/tex]
[tex]\therefore \text{Force F=}m\times a\\\Rightarrow F=3.57\times 0.6\\\Rightarrow F=2.14\ N[/tex]

A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 18 A of current: through the torso of person in 2.0 ms- (a) How much charge moves during this time
Answers
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
[tex]q=It[/tex]
Put all the values,
[tex]q=18\times 0.002\\\\q=0.036\ C[/tex]
So, 0.036 C of charge moves during this time.
