3) Magnets are used to separate steel cans from aluminum cans in recycling plants. How can
they be used for this?
(Will give brainliest if it's a proper answer)
Answer:
Since steel contains iron (a magnetic metal), the magnets will attract the steel cans since aluminum is not magnetic. This is used to separate the steel cans from the aluminum cans so they can be recycled separately.

Answer:
4. Force = 178.6 Newton.
5. Acceleration = 2.28 m/s².
6. Force = 178.6 Newton.
Explanation:
4. Given the following data;
Acceleration = 3.8 m/s²
Mass = 47kg
Force = mass * acceleration
Force = 47 * 3.8
Force = 178.6 Newton.
5. Given the following data;
Force = 785N
Mass = 345kg
Acceleration = force/mass
Acceleration = 785/345
Acceleration = 2.28 m/s²
6. Given the following data;
Acceleration = 6m/s²
Force = 32N
Mass =force/acceleration
Mass = 32/6
Mass = 5.33 kilograms

A book that weighs 0.35 kilograms is kept on a shelf that’s 2.0 meters above the ground. A picture frame that weighs 0.5 kilograms will have the same gravitational potential energy as the book when it’s raised to a height of ____
meters.
(Use PE = m × g × h, where g = 9.8 N/kg. )
Answer:
E p = m · g · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J
( same gravitational potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9 h
h = 6.86 : 4.9
h = 1.4 m
Answer: 1.4 M

He does a battery generate electrical energy?
A uniform meter rule is balanced by 80N and 20N from its ends. Find the position of its pivot from the 20N end. Show your working please
Answer:
80 cm
Explanation:
From the diagram attached,
Sum of clockwise moment = sum of anticlockwise
ΣACW = ΣCW
20x = 80(100-x)
Solve for x
20x = 8000-80x
20x+8x = 8000
100x = 8000
x = 8000/100
x = 80 cm.
The position of its pivot from the 20 N end is 80 cm.

1. Infer how the height of the lines on a seismograph change with an increase in
earthquake magnitude.
Answer:
his movement is proportional to the intensity of the earthquake,
Explanation:
An earthquake is a record of the intensity of an earthquake as a function of time.
Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.
And the in x corresponds to time
The lines on a seismograph indicate the magnitude of an earthquake. The lines from the seismograph are indicative of seismic waves that the seismograph has recorded.
When there is a straight line on the seismograph, it means there are no earthquakes. However, if the lines become wiggly, it means that the ground is shaking.
How Earthquake Magnitude is measuredThe magnitude of the earthquake is determined from the logarithm of the amplitude of waves recorded by the seismographs.
In order to understand the amplitude of waves, you'd have to be versed with the anatomy of waves. Once the logarithm is computed (after adjustments for the distance between the seismographs and the epicenter of the earthquakes), it is checked against the Richter Magnitude Scale in order to place the earthquake in a category.
For example, an earthquake may be considered moderate if the adjusted amplitude of the waves recorded on the seismograph records 5.3 on the Richter Scale. On the other hand, a rating of 6.3 is considered a strong earthquake.

a student is supplied with the following pieces of equipment:
• a small metal ball
• table tennis ball
• metre rule
• stop clock
• calculator
• light gate
• data logger
describe how the student can use this, or other additional equipment, to determine an accurate value for the acceleration of free fall (g). the student need not use all the equipment. show clearly what measurements should be taken and how the students should use these in determining (g). describe one source of error and how this might affect the value of (g).
(6 marks/year9/gcse)
Explanation:
Use a meter stick, small metal ball, stopwatch, calculator.
Have the students mark off a vetrtical distance from which to drop the metal ball. Ready the stopwatch, and start when the object is dropped and stop when the object contact the ground. Repeat 5 times and average the stopwatch times.
Now, use the formula d=vo+(1/2)at^2
There's no initial velocity, so d=(1/2)at^2
We know time and distance, so we can solve for a, acceleration.
2d=at^2
(2d)/(t^2)=a
Now, input the numbers gathered in the experiment in meters and seconds.
One source of error is human error (stopwatch timing)
Air resistance (although pretty negligible)
How to calculate the period of a wave?
Answer:
The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ. The wave frequency and the period are inversely related to one another.
Explanation:
T = 1 / f is the formula to calculate the period of a wave.
What is the period of the wave?The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds.
The calculation of period of wave is:
The formula for period is T = 1 / f ,
where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.
To get period from frequency, first convert frequency from Hertz to 1/s.
Period refers to the time for something to happen and is measured in seconds/cycle.
In this case, there are 11 seconds per 33 vibrational cycles.
Thus the period is (11 s) / (33 cycles) = 0.33 seconds.
Therefore,
T = 1 / f is the formula to calculate the period of a wave.

Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of wood is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling?
Answer:
22.22m/s
Explanation:
The momentum before a collision = momentum after collision so...
work out the momentum of the first object (the bullet)
its p = mv
0.04 kg × 300 m/s = 0.54 kg × v
rearrange this to find v which is 0.04 x 300 = 12
so 12 = 0.54 x v
12/0.5 = v
v = 22.22m/s
