how is force spread over long and short durations of time?
I think you're having trouble with it only because of how you're trying to look at it.
Don't try to imagine "spreading force" over time. Just think about how long the force lasts !
Like . . .
If you push your doll stroller for 5 seconds, you'll get it up to a certain speed.
Next time, if you push it again with the same force, but you keep pushing for TEN seconds, you'll get it up to a faster speed.
Technically:
(force • time) = impulse.
You gave it more impulse the second time, so it got more momentum from you.
A net force of 20 N is applied to a 5 kg object. What is the acceleration of the object?
Answer:
[tex]4ms^{-2}[/tex]
Explanation:
F = ma
Rearrange to get acceleration on its own:
a = [tex]\frac{F}{m}[/tex]
Substitute 20 for F and 5 for m:
a = [tex]\frac{20}{5}[/tex] = 4 meters/second/second
Find the average net force.
Answer:
givenmass= 3.5 kg
distance covered= 0.4m
inital speed = 1.5 m/sec
final speed = 0 m/sec
To findnet force
solutionformula for force :
[tex] \fbox{f = m.a}[/tex]
In order to find the force we need to find the acceleration.
According to third equation of Kinematics-
[tex] \bold{ {v}^{2} = {u}^{2} + 2as}[/tex]
where,
v= final velocity
u=inital Velocity
a=Acceleration
s=Distance covered
put the value in the above equation
0= (1.5)²+ 2a x 0.4
-2.25= 0.8a
a = -2.25/0.8
a= - 2.8125 m/sec²
now put the value 0f accleration in formula of force
F = m.aF = 3.5 x - 2.8125
F= -9.84375 N
A car increases velocity from 30 m/s to 60 m/s in 4 seconds. Calculate the average acceleration of the car over this time.
0.3 m/s2
7.5 m/s2
0.6 m/s2
4.8 m/s2
Answer:
B.7.5m/s2
Explanation:
average acceleration=change invelocity/time taken
a=(60-30)/4
=7.5m/s2
The average acceleration of the car 7.5 m/s²
The parameters given in the question are;
initial velocity= 30 m/s
final velocity= 60 m/s
time= 4 seconds
The formula that can be used to calculate the average acceleration is
= final velocity-initial velocity/time
= 60-30/2
= 30/2
= 7.5
Hence the average acceleration is 7.5 m/s²

A student is given an investigation of the human body. The student is to predict how new cells are created. According to cell theory, which prediction is correct?
A.Cells grow and develop, but are never replaced.
B. New cells are created from pre-existing cells in the human body.
C. New cells are created but quickly die during cell growth.
D. Humans are born with all the cells they will ever need.
Answer:
B. New cells are created from pre-existing cells in the human body.
Explanation:
According to the cell theory, the correct assumption from the student's investigation is that "new cells are created from pre-existing cells in the human body".
One of the postulates of the cell theory is that all cells originated from pre-existing cells. Also, a cell is the fundamental unit of life.So, the student is correct to say that new cells are created from pre-existing cells in the human body.

True or False. A loud noise gives off less energy than a quiet noise.
Answer:
True
Explanation:
A loud noise cancels out
A loud noise gives off less energy than a quiet noise : False
Meaning of loudnessLoudness is the intensity of sound heard in a given period. it is dependent on the amplitude of the sound waves.
The loudness of a sound is proportional to the square of the amplitude of the sound wave, meaning that the larger the amplitude of wave, the more the intensity and the more the sound.
Since waves carry energy along, it means a wave with a large amplitude transfers more energy and therefore loud sound.
In conclusion, the louder the sound the more energy it gives off and the quieter the sound the less energy it gives off.

1. In your own words explain what happens at a subduction zone. 2. In your own words explain what happens at a mid-ocean ridge. 3. At a subduction zone what causes magma to rise?
Answer:
1. The subduction zone serves as the meeting point for two tectonic plates.
2. At the Mid- Ocean ridge, decompression melting occurs.
3 What causes the magma to rise is the increase in pressure caused by collection of gases by the magma.
Explanation:
Subduction zone is define as a zone where tectonic plates ( an oceanic plate slides beneath a continental plate) meets and contributes to the rise of magma to the surface in geological sciences.
At the Mid - Oceanic ridge, decompression melting occurs. As mantle ascends beneath the mid-ocean ridge, less and less rock lies above it, so large pressure changes occur, which leads to melting. The melt is less dense than the solid, and rises to the surface to form the oceanic crust.
At the subduction zone the magma that is formed is usually made up of silica rich lava. Thick silica rich magma does not release the gasses very easily so they build up inside the magma chamber. As the gasses collect in the chamber, the pressure rises. It is possible for the pressure to rise so much that the chamber cannot contain the magma and it erupts explosively.
Ashley is flying a plane that has to reach a gradient of 360m/km in order to take off and not crash. Her goal is to travel from sea level to an elevation of 1000m at a distance of 2.8km. Calculate the gradient of Ashley’s flight and determine if she will crash!
Answer:
She is likely to crash because her flight gradient is lesser than the flight gradient required gradient to avoid crashing
Explanation:
The given parameters are;
The required gradient of the plane Ashley is flying needs to reach in order to take off and not crash = 360 m/km
The initial elevation of the plane Ashley is flying = Sea level = 0 m
The goal Ashley intends to make = Elevation of 1000 m at 2.8 km. distance
∴ Ashley's goal = Traveling from sea level to 1000 m at 2.8 km horizontal distance
We have;
The gradient = Rate of change of elevation/(Horizontal distance)
Therefore;
The gradient of Ashley's flight = (1000 - 0)/(2.8 - 0) = 357.143 m/km
The gradient of Ashley's flight ≈ 357.143 m/km which is lesser than the required 360 m/km in order to take off and not crash, therefore, she will crash.
Two balls have the same mass. One ball moving along the positive x–axis and the other ball moving along the positive y–axis undergo perfectly inelastic collision. What can you say about the motion of the balls after the collision?
A.
The balls stick and move together.
B.
The balls separate immediately.
C.
The first ball stops while the other ball starts moving.
D.
The two balls travel off in opposite directions, 180° apart.
Answer:
A. The balls stick and move together.
Explanation:
When a bodies undergo perfectly inelastic collision, the two bodies stick together after the collision and begins to move.
In this collision, kinetic energy is not conserved. For perfectly elastic collision, the two bodies conserve kinetic energy and begin to move apart.
Kinetic energy is not conserved because some of the energy gets converted into other forms of energy.
How does the initial vertical velocity (right after it starts moving) of a horizontally launched projectile compare with it's final vertical velocity (right before it hits the ground)?
They are equal
The initial velocity is greater
The final velocity is greater
Answer:
The final vertical velocity is greater than the initial vertical velocity
Explanation:
Horizontal Motion
When an object is thrown horizontally with a speed vox from a height h, it describes a curved path ruled by gravity.
The resultant motion is the composition of the vertical motion and the horizontal motion.
The speed in the horizontal direction is always constant:
vx=vox
The speed in the vertical direction starts from zero and gradually increases in time:
vy=g.t
When the object was just launched, t=0, and its vertical velocity is 0
After some time has passed, the object is about to hit the ground, and its vertical velocity is greater than zero, thus:
The final vertical velocity is greater than the initial vertical velocity
