Answer:A
Explanation:
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.

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
how is the lens able to change its refractive power?
Answer:
The lens can sharpen the curvature of its front and back surfaces, increasing its focusing power.
Explanation:
A lens can change its refractive power through sharpening of the curvature of its front and back surfaces, thereby increasing its focusing power.
What is refractive power of lens?The optical power of a lens is the degree to which the lens is able to converge or diverge light.
The optical power of a lens is measured in Diopters, and obtained by taking the reciprocal of the focal length in meters.

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.

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

A plane mirror moves towards the object with a velocity of 2m/s and the object itself moves towards the mirror with a velocity of 5m/s. What is the velocity of the image approaching towards the object..
Answer:
3.33 m/s
Explanation:
1/2 = 1/5 + 1/x
1/x = 1/2 - 1/5
1/x = 5/10 - 2/10
1/x = 3/10
x = 10/3

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.
