Explanation:
5. Fill in the blanks with either "More," "Less," or "The Same."
a) If an object has more mass than another object, it will accelerate_less____
b) In order to accelerate an object more, one would need to apply_more____ force.
c) If an equal force is applied to two different objects, the less massive object will accelerate_more___
The answer is less, more and more.
Relationship between mass and accelerationIf an object has more mass than another object, it will accelerate less. In order to accelerate an object more, one would need to apply more force. If an equal force is applied to two different objects, the less mass of an object will accelerate more
The acceleration of an object depends directly on the force acting upon the object, and inversely on the mass of the object.

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.
You escape the evil car pushing cat and leave him back behind you in the road. He tries to chase you, though. He weighs 2kg and his legs apply 50N of force. How fast does he accelerate?
Answer:
25 m/s²
Explanation:
F = m × a
50 N = 2 kg × a
a = 50 N : 2 kg
a = 25 N/kg
a = 25 m/s²

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.

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.

Sue and Jenny kick a soccer ball at exactly the same time. Sue’s foot exerts a force of 68.9 N to the north. Jenny’s foot exerts a force of 85.4 N to the east.
a) What is the magnitude of the resultant force on the ball?
Answer in units of N.
Explanation:
the magnitude of the resultant force =
√(68.9² + 85.4²)
=√(4,747.21 + 7,293.16)
=√12,040.37
= 109.7 N
»Sue's style feet (north) = 68.9N
»Jenny style feet (East) = 85.4N
So, the resultant force on the ball is
= √(68.9² + 85.4²)
= √(4,747.21 + 7,293.16)
= √(12,040.37)
≈ 109.72N✅

Blue bumper car, traveling east with a force of 100 N, runs into a yellow bumper car traveling west with a force of 300 N. Because the net force will be -200 N. one of the cars will be pushed backward. Which one?
Answer:
the blue bumper car
Explanation:
because the yellow bumper car is coming in with much more force
and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N
then it almost because a fight between 300N vs 100N
and obviously, the 300N will win and the 100N will be pushed back
