Information travels at 120 metres per second in neurones. Calculate the time it would take for the information to travel 2.3 m along a neurone. Give your answer in milliseconds.
Answer:
5 remainder 5
Explanation:
divide 120 by 2.3
To calculate the time it would take for information to travel a certain distance along a neuron, you can use the formula: Time = Distance / Speed.
Given that the information travels at 120 meters per second and the distance is 2.3 meters:
Time = 2.3 m / 120 m/s
Time ≈ 0.019167 seconds
To convert seconds to milliseconds, multiply by 1000:
Time in milliseconds ≈ 0.019167 s * 1000 ms/s ≈ 19.167 ms
So, it would take approximately 19.167 milliseconds for the information to travel 2.3 meters along a neuron.

A raindrop was 16meters above the ground, falling straight down at a constant velocity. It took the raindrop 2seconds to fall half the distance to the ground. What was the raindrop's velocity?
what is the answer
Answer is 4 m/s
Step-by-step explanation:-Let :-
Constant velocity = v
Time (t) = 2 seconds
Height (h) = 16 metres
As the raindrop has constant velocity, we can write that :
[tex] \frac{h}{2} = vt[/tex]
Substituting the values, we get,
[tex] \frac{16}{2} = v \times 2[/tex]
[tex]8 = v \times 2[/tex]
[tex] \frac{8}{2} = v[/tex]
[tex]v = 4 \: m/s[/tex]
Therefore, the velocity of the raindrop is 4 m/s.

which particle is transferred from one object to another to create a static charge?
Answer:
The answer is A: Electron
Because they are loosely bounded and can be easily transferred. The protons are bounded to the nucleus so they cant be transferred.
It cant be an atom or a molecule.
Explanation:
Can some one help me whith the answer
→ The charge in electron charge Q(e) is equal to the charge in coulombs Q(C) times 6.24150975⋅1018:
1C = 6.24150975⋅10¹⁸e
Q(e) = Q(C) × 6.24150975 × 10¹⁸
Q(e) = 96,500 × 6.24150975 × 10¹⁸
Q(e) = 6.02305690875 × 10²³
which is round off to
→ 6.03 × 10²³ electrons

Be affectionate. Most girls love getting showered with affection and compliments from a guy they care about. Some girls can be insecure, and love being reassured a lot. To be affectionate, just give her a gentle touch, put your arm around her, hold her hand, or do whatever you can do to give her a little bit of physical touch. This doesn't mean you have to use everything you have on her, pick the right moments to let her know you care and it'll mean a lot more than having your arm around her for four hours.DO YOU KNOW SHE LIKE YOU?Look for open body language. When a girl likes you, she will face in your direction. If a girl has her torso turned towards you in an open manner, this means that she is confident talking with you. If she has a closed body position, namely crossed arms or legs, she may be shy or nervous to talk to you or she may simply be creating a barrier to signal that she is uninterested.[1]When she is sitting with her legs crossed, watch her feet. If they are pointed towards you, it might mean that she likes you and wants to get closer to you.[2]Generally speaking, a girl will stand closer to you and will have more relaxed body language if she feels comfortable around you — for example, she'll have relaxed shoulders and she won't cross her arms, But, everyone's personality and cultural upbringing are different, so don't take it as a sign she's not into you if this isn't the case.[3]Calculate the average force a 60.0-kg sprinter exerts backward on the track to accelerate from 2.00 to 8.00 m/s in a distance of 2.50m
Hi there!
Because of Newton's Third Law, the force exerted by the sprinter on the track is equal and opposite to the force exerted by the track on the sprinter.
We can begin by calculating the sprinter's acceleration. Use the equation:
vf² = vi² + 2ad
Rearrange for acceleration:
(vf² - vi²)/2d = a
Plug in values:
(8² - 2²)/2(2.5) = 60/5 = 12 m/s²
Calculate the force:
∑F = ma
∑F = 60 × 12 = 720 N. This is the amount of force exerted by the track on the sprinter in causing him to accelerate forward.
Thus, the backward force exerted by the sprinter on the track is the opposite, or -720 N.

What resistance does a 25 W light bulb have if 12.6 V is applied to it?
(3 marks)
Answer:
Explanation:
W = 25 Watts
V = 12.6 Volts
I = ? I is the current in amperes.
Solution
25 = 12.6 * I
I = 25 / 12.6
I = 1.98 amperes
V = 12.6
I = 1.98
R = ??
V = I * R
12.6 = 1.98 * R
R = 12.6 / 1.98
R = 6.35 ohms

the process of submerging an object to determine its volume is called
Answer:
Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method. Often taught in chemistry or other science classes, this method is known for its simplicity and accuracy.
Explanation:
Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.
What is displacement?Shortest distance between two point are called as displacement, or we can say that when a body moves between two points the total lengths between two points are called as distance but the shortest distance between two point is called as displacement. Displacement is measured in meter and it is a vector quantity. Displacement may became zero but distance never became zero.
In above problem we cam say that in a race car start form a point and reaches at the same point then it's displacement is zero because there is no shortest distance. Displacement is measured in meter and it is a vector quantity. Displacement may became zero but distance never became zero.
Therefore,Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.

What role does a volcano play in our planets dynamic internal activity
Answer:
Volcanic activity acts as a window to a planet's interior. The type of volcanism and the composition of the lava give scientists a peak underneath the crust.

15. Starting from rest, an object rolls freely down an incline that is 10 m long in 2 s. The acceleration of the
object is approximately?
Answer:
a = 5m/s^2
Explanation:
Vi=0 m/s
ΔY=10m
Δt=2s
find acceleration
With the givens and the acceleration being the only one missing, we can safely use the Δy = Vi Δt + 1/2 a (Δt)^2 formula
Plug it in and we get:
10 = 0 x 2 + 1/2 a (2)^2
10 = a2
10/2 = a 2/2
a = 5 m/s^2
