This took me a short while to figure out, but I am still not entirely sure if this is correct, this is just from my basic understanding of Newtons Second Law of Motion.
You have a 4kg cart with a force of 20N acting on it.
The formula for working out the acceleration is.
a=Fnet÷mass
Substitute in the information.
a=20N÷4kg
Now you solve it to give you.
a=5m/s
So now what you should be able to do is figure out that after 10 seconds the cart travelling at 5m/s would have travelled 10 metres.
This is achieved by finding out how many 5's go into 10 which is 2.
So you do 5×2 which equals 10.
The 4kg cart has travelled 10 meters in 10 seconds with a force of 20N acting upon it.
I hope that this has helped you.
Answer:
They all burn fossil fuel is the correct answer.
Explanation:
Cars, power plants, and furnaces all burn fossil fuels such as coal, natural gas, heavy oils, petroleum, oil.
Burning of these fossil fuels results in a release of a huge amount of carbon dioxide and sulfur dioxide gas, into the surrounding that causes air pollution, global warming, acid rain, and these gases present in the environment are highly corrosives and makes suffocating in the environment.
The magnetic flux is 2.6 x 10-3 Wb
<h3>
What is Magnetic flux?</h3>
Magnetic flux is the measurement of the total magnetic field that passes through a given area.
It is a useful tool for helping to describe the effects of the magnetic force on something that occupies a given area.
Area of triangle inside the field, A = 1/2 x 0.1 x 0.2 x sin 60 = 0.00866 m2
therefore, magnetic flux = B x A = 0.3 x 0.0086 = 2.6 x 10-3 Wb
(B) Applying Lenz's law, the direction of the current will be clockwise

My teacher taught me that besides the type of wave, wavelength doesn't change unless you shorten the wave, and she used string as an example. Making the string shorter causes the wavelength to decrease so it can't be B. Your answer is A
