An astronaut in space pushes a piece of equipment to get it into the correct position. What does Newton's third law of motion tell us about this? Question 5 options: The equipment would have accelerated much faster if the astronaut had applied a much greater force to it. The equipment will "push back" on the astronaut with the same amount of force. The equipment would have stayed in the same exact location indefinitely until the very moment the astronaut applied force to it. The equipment will continue moving in the same direction indefinitely unless another force is applied to stop it.
Answer:
Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
Explanation:
Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
What is equal and opposite according to Newton's third law?According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

Which law describes the magnetic field in a nonlinear wire? A. Faraday's law B. Gauss's law C. Ohm's law D. Ampère's law
Answer:
D. Ampère's law
Explanation:
I got a 5 on plato
The law that describes the magnetic field in a nonlinear wire is Ampère's law. The correct option is D.
What is Ampère's law?Ampère's law is a fundamental law of electromagnetism that describes the relationship between the electric current flowing through a wire and the magnetic field it produces. It states that the magnetic field around a closed loop is proportional to the electric current passing through the loop.
Mathematically, Ampère's law can be expressed as:
∮ B ⋅ dl = μ0I
Where B is the magnetic field, dl is an element of the closed loop, μ0 is the magnetic constant, and I is the current passing through the loop. The integral is taken around a closed path that encloses the current-carrying wire.
Ampère's law is useful in calculating the magnetic field produced by a current-carrying wire or a system of wires. It also helps to understand the behavior of magnets and how they interact with each other.
It is important to note that Ampère's law only applies to steady currents and does not take into account the effects of changing electric fields. For this, Faraday's law of electromagnetic induction is used.
Here in the Question,
A. Faraday's law: This law describes the relationship between a changing magnetic field and an induced electric field. It states that the magnitude of the induced EMF is proportional to the rate of change of magnetic flux.
B. Gauss's law: This law deals with the electric field and its relationship with electric charges. It states that the electric flux through a closed surface is proportional to the charge enclosed within the surface.
C. Ohm's law: This law describes the relationship between current, voltage, and resistance in a conductor. It states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.
Therefore, The correct answer is D i.e. Ampère's law.

2. Elizabeth drove 30 miles to the south, then drove 50 miles to the east. Draw a
vector diagram that shows her resultant displacement. Be sure to label all vectors.
Answer: R = 58.3 miles
Explanation:
Displacement is a vector quantity. That is, it has both magnitude and direction.
As Elizabeth drove 30 miles to the south, then drove 50 miles to the east. The resultant displacement can be achieved by using pythagorean theorem
R^2 = 30^2 + 50^2
R^2 = 900 + 2500
R^2 = 3400
R = sqrt(3400)
R = 58.3 miles
The vector diagram that shows her resultant displacement is attached as a file.

When leaving a fish tank, a ray moving at 31.0 deg in glass (n = 1.50) exits into the air. At what angle does it enter the air?
Answer:
50.5
Explanation:
Using Snell's Law, you can rearrange the equation to solve for the 2nd angle. The most important part of this question is remembering to use the 1.50 n in the numerator and 1.00n in the denominator. The reason for this is because 1.50's degree is already found: 31.0. You're looking for the degree where the ray hits air, which would be the 1.00 n. So, the equation looks like this: Sin^-1 (1.50sin(31)/ 1.00). After solving the equation, you get 50.5 or 50.6 if you round up. I hope this was helpful! :)

Americium-241 is used in smoke detectors. It undergoes alpha decay with a half life of 432 years. The alpha particles ionize some of the air near the americium-241 source, and these charged ions are collected on a metal plate that has a small voltage applied to it. The collected particles cause a small electric current to flow in the detector. If smoke particles get in between the americium-241 source and the detector and reduce the current, the alarm is triggered. A typical smoke detector experiences 370000 alpha decays each second. How much time is needed for the number of decays to reduce to 93000 decays per second?
Answer:
860.6 years.
Explanation:
The parameters given are;
Initial detector activity = 370000 alpha decays per second
Final detector activity = 93000 alpha decays per second
Formula for time to change in activity is given by the following relation;
[tex]t_{93000} = \dfrac{-ln\dfrac{A}{A_0} }{\lambda} = \dfrac{-ln\dfrac{93000}{370000} }{5.08 \times 10^{-11}} = 2.72 \times 10^{10} \, seconds[/tex]
t₉₃₀₀₀ = 2.72 × 10¹⁰ seconds = 860.6 years.

How many kW*h (kilowatt hours) of electricity is consumed by a 500 w light bulb that burns
for seven hours?
Answer: 3.5 kWh
Explanation:
Given that the
Power P = 500 W
To convert watt to kilowatt, divide it by 1000
Power P = 500/1000 = 0.5 kw
Time t = 7 hours
Power is the rate at which work is done. That is,
P = WD/t
Cross multiply
WD = Pt
Where workdone WD is the energy E consumed in kWh .
Substitute P and t in the formula above.
E = 0.5 × 7
E = 3.5 kWh
Therefore, 3.5 kWh (kilowatt hours) of electricity is consumed by a 500 w light bulb that burns.

A 60 kg man jumps down from a 0.8 m table. What is the speed when he
hits the ground? ( Take g= 10 m/s2)
Answer: Speed = 4 m/s
Explanation:
The parameters given are
Mass M = 60 kg
Height h = 0.8 m
Acceleration due to gravity g= 10 m/s2
Before the man jumps, he will be experiencing potential energy at the top of the table.
P.E = mgh
Substitute all the parameters into the formula
P.E = 60 × 9.8 × 0.8
P.E = 470.4 J
As he jumped from the table and hit the ground, the whole P.E will be converted to kinetic energy according to conservative of energy.
When hitting the ground,
K.E = P.E
Where K.E = 1/2mv^2
Substitute m and 470.4 into the formula
470.4 = 1/2 × 60 × V^2
V^2 = 470.4/30
V^2 = 15.68
V = square root (15.68)
V = 3.959 m/s
Therefore, the speed of the man when hitting the ground is approximately 4 m/s
Was the object accelerating during the time interval labeled “B”?
A) Yes
B) No
There's not enough information in the graph to determine whether it was or it wasn't. It could have been, but we can't tell.
Before I explain this answer, it's VERY important to know exactly what "accelerating" means:
-- "Accelerating" does NOT always mean "speeding up".
-- "Accelerating" means ANY change in velocity.
-- That can be ==> speeding up, or ==> slowing down, or ==> turning.
This graph is labeled "Velocity vs Time", but it isn't really. "Velocity" means speed AND direction. The graph only shows us the object's speed, but nothing about its direction.
During time-interval-B, the speed isn't changing, but the object could still be changing direction, like turning a corner, or on a curved path. We don't know. The graph doesn't show us that information.
The object could be accelerating during time-interval-B. It's true that the speed wasn't changing. But maybe the direction was. If the direction was changing, then we have to say the object was 'accelerating' during the interval labeled B .
Two identical cows fell into a muddy hole. One fell on its side and the other on its feet.
Which one sunk furthest into the mud and explain your answer
Answer: The one that fell on its feet.
Explanation: The sinking of the two cows will depend on the pressure exert on the mud.
Pressure is the ratio of force to area.
The one which fell on its side would exert lower pressure because of its larger side of area. While the one that fell on its feet will exert greater pressure because of small area of its feet.
Therefore, the one that fell on its feet will sink furthest into the mud because of the ratio of the force to area of its feet ( pressure) is higher.

What is the basic premise of the universal gravitational law? Question 7 options: Each object in the universe that has mass attracts every other object that has mass. The motion of an object in a circular path is kept along that path due to gravitational force. The force of an object is equal to the mass of the object multiplied by its acceleration. The acceleration of an object in freefall will always be 9.8 meters per second squared, due to gravitational pull.
The correct answer is A. Each object in the universe that has mass attracts every other object that has mass.
Explanation:
The gravitational law proposed by Newton explains how the gravitational force works. The basic idea or premise in this law is that the gravitational law exists in all the universe, and occurs with all objects that have a mass. This includes the fact all objects or particles that have a mass attract all other objects with mass but this is also influenced by the distance between the objects, and the masses of each object. In this way, the gravitational force is equal to the gravitational constant multiplied by the mass of the two objects and divided by the distance between the objects.
Answer:
A. Each object in the universe that has mass attracts every other object that has mass.
Explanation:
The universal law of gravitation states that every object in the universe that has mass attracts every other object in the universe that has mass. The force increases as the mass of the objects increases, and decreases as the objects become further and further apart.
Light of wavelength 525 nm passes through a double slit, and makes its second maximum (m = 2) at an angle of 0.482 deg. What is the separation of the slits , d, IN MILLIMETERS ?
Answer:
d = 0.124 mm
Explanation:
It is given that,
Wavelength of light is 525 nm
It makes second maximum at an angle of 0.482 degrees
We need to find the separation of the slits.
For 2nd maximum, the equation for double slip experiment is given by :
[tex]d\sin\theta=n\lambda[/tex]
d = separation of the slits
[tex]d=\dfrac{n\lambda}{\sin\theta}\\\\d=\dfrac{2\times 525\times 10^{-9}}{\sin(0.482)}\\\\d=0.124\ mm[/tex]
So, the separation of the slits is 0.124 mm.
