Answer: this answer is D. That's what I think it is
Explanation:
Answer:
Explanation:
The oil drop remains stationary when the electric force on it and the gravitational force are balanced, so we have:
where
q is the charge of the oil drop
E is the electric field strength
m is the mass of the drop
g is the acceleration due to gravity
here we have
So the charge of the drop is

The magnitude of a velocity vector is 60 m/s.
To find the magnitude, the given values are,
x - components = 36 m/s
y - components = 48 m/s
<h3>What is magnitude?</h3>
- The term magnitude can be defined as “ quantity ”.
- For instance, the magnitude can be used for describing about the comparison of speeds.
- It can also be used to explain the distance travelled by an object or to explain the amount of an object in terms of its magnitude.
- Magnitude of the velocity vector is total value which is square root of the value.
The magnitude of the vector can be,
| a | = √ ( x² + y² )
Substituting the values of x component and y component given,
= √ ( 36² + 48² )
= √ ( 1296 + 2304)
= √ 3600
= 60 m/s
The magnitude is found to be 60 m/s.
Hence, Option B is the correct answer.

When action potentials reach the end of the axon, they stimulate opening of Ca2+ channels, causing a release of neurotransmitters to the post-synaptic cell. How does and impulse propagate down the axon? The stimulus causes a start of the action potential and it moves down the axon without the ions moving down
