Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg
Answers
Answer
To understand this concept it is necessary to understand Newton's Second Law
According to Newtons Second law applied force is equal to rate of change of momentum of a body.
Mathematically,
here, is rate of change of momentum with respect to time
It means If two eggs fall from same height,one on softer surface and other on hard surface that time the momentum of both eggs will remain equal at both the surfaces. But, impact time will be different. On hard surface egg will stop almost instantly so impact time will be small and hence the force on egg will be large therefore the egg will breakup.
On the other hand on the soft surface like a cotton, egg will not stop instantly but it will slow down for a few seconds and then stop due to which the time of impact will increase. Therefore the force on egg will be less and it won't break up.

When Tyler drives 50 km north and then drives back 30 km south, we have:
1. The distance that he covers is 80 km.
2. Tylor's displacement is 20 km.
1. The distance is a scalar that is given by the sum of the kilometers traveled by Tyler as follows:
Hence, the distance traveled by Tyler was 80 km.
2. The displacement is a vector that depends on the direction of travel. Takin the north direction as positive we have:
Therefore, Tyler's displacement is 20 km.

I hope it helps you!
Answer:
80 km is distance and 30km north is displacement
Explanation:
distance= 50+30=80km
displacement= 50-20=30
his displacement is 30km north
4 minutes. What is its speed?
Answers
It's speed is exactly 6.4 meters per 4 minutes.
In the more familiar units, that's
(6.4 m / 4 min) = 1.6 meters per minute
(1.6 m / min) (100 cm/m) ( 1 min / 60 sec) = 2-2/3 cm per sec.
(1.05 inch per second, rounded)
(160.3 furlongs per fortnight, rounded)
The speed of the tortoise can be calculate as follows:
where
S is the distance travelled by the tortoise
t is the time taken
In this problem, S=6.4 m, while we should convert the time into seconds:
Substituting the numbers into the equation, we find the speed:
b. False

The statement ‘An electromagnet is a strong magnet that can be turned on and off’ is true. The answer is letter A. An electromagnet can be made through wrapping the wire that has an electric current around a nail. It can be increase through the number of loops wrapped around the metal.
Answer:
true
Explanation:
Answers
the situation is called "free fall".
The motion is uniformly accelerated. The object falls
straight toward the center of the other object in whose
gravity it shares, and its speed increases at a constant
rate.
When this happens on or near the surface of the Earth,
the rate is (9.8 meters per second greater) for each
second of falling.
True free-fall is never observed in daily life. Whenever
we see an object falling, it is always falling through air,
which counteracts the force of gravity to a greater or
lesser degree, depending on the object's size, shape,
weight, surface texture, and speed through the air.
