Answer:
The new electric field strength of this charge is half of the strength of the other charge.
Explanation:
The electric force acting on the charge particle is given by :
F = q E
Where
q is the charged particle
E is the electric field
If the magnitude of a charge is twice as much as another charge, q' = 2q, but the force experienced is the same, then the new electric field is given by :
So, the new electric field strength of this charge is half of the strength of the other charge. Hence, this is the required solution.
Answer:
B
Explanation:
to see how fast she is going per second, you would have to divide the distance traveled by the seconds it took to travel the distance
To develop this problem it is necessary to apply the concepts related to Broglie hypothesis.
The hypothesis defines that
Where,
P = momentum
h = Planck's constant
The momentum is also defined as,
P = mv
Where,
m = mass
v = Velocity
PART A) Replacing at the first equation
Our values are given as,
Re-arrange to find v, we have:
PART B) From the kinematic equations of movement description we know that velocity is defined as displacement over a period of time, that is
Re-arrange to find t,
the age of the universe.
Answer:
average and instant
Explanation:
The average speed is the ratio of the <u>total path traveled and the time it took to travel that path</u>, that is why the first space must be average speed, this because it takes into account the total amount of distance, and the total amount of time.
Instant speed, is the speed an objet (in this case a car) has in <u>a particular moment in time</u>, for this speed it doesn't matter the distance or the time that the car has traveled, it only matters the speed in that moment, that is what the speedometer measures, thus the second blank space must be instant speed.
