Answer:
3.5 m
Explanation:
The wording at the end is not very clear, but I am pretty sure that the question is asking for the total distance moved from the starting point. If this is the case, the answer is found by subtracting the two vectors from each other because they are in opposite directions. This gives you 3.5 m. If the question was asking for the actual total distance moved, you would just add them together and get 14.3 m, but I don't think that is what the question is asking for. Hope this helps! :)
Answer:
|q1| / |q2| = 1/7
Explanation:
We are told that both particles are in the same magnetic field, B.
The charge of the first particle is q1
The charge of the second particle is q2
Let the speed of particle 1 be v1.
Let the speed of particle 2 be v2.
The magnetic force acting on particle 1 due to the magnetic field, B, is:
F1 = |q1| * v1 * B
The magnetic force acting on particle 2 due to the magnetic field, B, is:
F2 = |q2| * v2 * B
We are told that both particles experience the same magnetic force. This means that F1 = F2
Therefore:
|q1| * v1 * B = |q2| * v2 * B
=> |q1| * v1 = |q2| * v2
|q1| / |q2| = v2/v1
We are told that the speed of particle 1 is seven times that of particle 2. Hence:
v1 = 7 * v2
Hence:
|q1| / |q2| = v2 / (7 * v2)
|q1| / |q2| = 1/7
The factors affecting the terminal speed of a falling object include:
its mass.
its surface area.
the acceleration due to gravity
Answer:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work? We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
