Answer:
The magnitude of the Force is and the direction is South
Explanation:
From the question we are told that
The magnetic field point due west and since East point toward the positive x -axis then this magnetic field would be mathematically represented as
Now from the question we are told that the kinetic energy is
Now this kinetic energy can be mathematically represented as
Where m is the mass of proton which has a general value of
Now making the subject of the formula
Substituting values we have
Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive
So the velocity would be
Now the magnetic Force can be mathematically represented as
Where q is the charge on the proton which has a general value of
Now substituting the value
Now according to Fleming's left hand rule the direction of the magnetic force is south toward the negative Y - direction
So the force can be denoted as
mass/volume = density.
if bigger than water, sinks
less than water floats.
Archimedes' principle, floatation, icebergs etc
Answer:
Statement 2 is wrong
Explanation:
To check the statements in this exercise, let's describe the main properties of electromagnetic waves. Let's describe the characteristics
* they are transverse waves
* formed by the oscillations of the electric and magnetic fields
* the speed of the wave is the speed of light
with these concepts let's review the final statements
1) True. Formed by the oscillation of the two fields
2) False. They are transverse waves
3) True. Can travel by vacuum as they are supported by oscillations of the electric and magnetic fields
4) True. They all have the same speed of light
Statement 2 is wrong
Answer:
Explanation:
Think about the equation for velocity. Its the change in position over the change in time. And now think about the formula for slope, its the change in y over the change in x. Now, if you have a position vs time graph, the slope is position over time, the direct formula for velocity. Therefore, the slope of a position vs time graph gives the velocity in that interval. You could take the derivative at that point and get the instantaneous velocity.
In the first argument, the only way to get a negative slope is if youre moving to the left of your initial position as you pass through time. So the claim isnt necessarily true. When you move away from the origin, that simply means youre moving through time.
In the second argument, a horizontal slope means the value is 0. That means there is a value of 0 for your velocity, aka standing still.
In the third argument, a positive slope means youre moving to the right of your initial position as you go through time.
The fourth one is incorrect. Speed is the magnitude of velocity, and the slope can be determined an any point besides vertical slopes, which would require time to literally stop.
I dont understand the very last part of what you posted, so try to make a decision based on what I just explained to you
Answer:
2.815 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Time taken with the acceleration is 94.25 seconds
Time = Distance / Speed
Difference in time = 97.065-94.25 = 2.815 seconds
