Answer:
Impulse=18Ns
Explanation:
Impulse= force*time
Plug in known values...
I=6N*3s
I=18Ns
The impulse produced by the force is 18Ns
What is Impulse?
Impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse= force*time Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.Given:
F= 6.0N
t= 3.0 s
On substituting these values in the above formula:
[tex]I=6N*3s\\ \\I=18Ns[/tex]
Thus, The impulse produced by the force is 18 Ns.

Now set the tension to low and wiggle the wrench to create more waves. Can you explain how moving the first point on the string, the one closest to the wrench, affects the next point on the spring? How does this fit with your understanding of the force of a stretched spring?
Answer:
When the string moves, it creates a very small change in the distance to the next point, th
Explanation:
When the string moves, it creates a very small change in the distance to the next point, this generates a restoring force that tends to push the string back, this small disturbance propagates along the string and is what creates the pulse.
This is similar to what happens when a spring is stretched and a restoring force is generated shaved by the law of shortening.
F = k Dx
Answer:
As the first particle travels upward, it pulls on the next particle, which follows the first particle upward. Then next in line is pulled up in turn, and so on. The motion of each particle follows the one before it, either up or down, with a slight lag in time. This succession of particles moving up or down travels along the string as a wave. Eventually, it pulls every particle along the string up and down in series.
Explanation:
Which of the following statements describes the electric force between a positive particle and a negative particle as they approach each other?
Answer:
They will Attract each other and act like magnets
Explanation:
When 2 positive or 2 negative particles are near each other they repel. When 2 neutral particles are together they do nothing, but when a positive and a negative are together their charges sort of overlap each other and they attract.
Distance and direction of an object's change in position from a starting point are:
Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.

Answer:
1. The human exerts a force when he pulls the bow back and launches it.
2. Gravity causes the arrow to fall down, and air resistance slows the arrow down, as it is in the opposite direction.
3. If the arrow has more mass, it would require to have a greater force exerted on it to make it fly farther. So the archer would most likely not reach as high of a top speed.

Bibek went to the swimming pool. he saw the pool to be shallower and is redy to jump into the swimmingpool . is it proper for him to jump? if not why ?
Answer:
A swimming pool appears shallower than it really is due to the phenomenon of REFRACTION. Due to refraction, from rarer medium( Air ) to denser medium ( water ), the pool looks shallower

Which part of the drum (Instrument)vibrates when it produces sound?
Answer:
Striking the head of the drum changes its shape and compresses the air inside the shell. the compressed air presses on the bottom head and changes its shape. then these changes are transmitted to the drum shell and reflected back and this action is repeated created a vibration.

Answer:
A. consumers
B. multi-cellular
Explanation:
Only plants have chlorophyll and only plants have a cell wall so C and D are out of the window. They are consumers because, they don't have photosynthesis so they have to eat. They are multi-cellular because, animals all have at least a brain, body, etc. Which all need millions of cells.
1)A 2.0 kilogram wooden object is a on a wooden surface. What is the maximum force of friction that can be produced in this system?
Answer:
fr = 7.84 N
Explanation:
To solve this exercise we must use Newton's second law, the case of translational equilibrium
F -fr = 0
F = fr
where F is the applied force and fr the friction force
for the Y axis
N -W =
N = W
N = m g
the friction force has the equation
fr = μ N
fr = μ m g
in this case they indicate the two materials that are in contact with wood on wood, so when reviewing the tables the coefficient of static friction is μ=0.4
let's calculate
fr = 0.4 2.0 9.8
fr = 7.84 N

Complete the statements about convection currents. Convection currents occur in fluids because of temperature and differences. Convection currents transfer energy throughout a fluid. They continue until all of the fluid is at the same temperature.
Answer:
density; thermal
Explanation:
Convection currents occur in fluids because of temperature and density differences. Convection currents transfer thermal energy throughout a fluid.
When a fluid is heated, the molecules closest to the heat source gets heated first and their temperature is raised. The rise in temperature lowers their density and as such, they move to the upper portion of the fluid to be replaced by yet-to-be-heated molecules at the upper portion.
When the replacement molecules also get heated, the same process occurs and a to-and-from rotational movement of molecules, also known as convection current, is created within the fluid. The to and from movement, thus, transfer thermal energy within the fluid until all the molecules within the fluid are at the same temperature.
Answer
density; thermal

9. During an egg toss, a catcher must cushion the egg by maximizing the time it takes to stop the
egg. Find the impulse applied to a 60.0-gram egg, if the egg has an initial velocity of 6.0 m/s as it
first touches the catcher's hand, and the egg is stopped within 50.0 cm.
Answer:
the impulse experienced by the egg is 0.053 kgm/s.
Explanation:
Given;
mass of the egg, m = 60 g = 0.06 kg
initial velocity of the egg, u = 6 m/s
height moved by the egg, h = 50 cm = 0.5 m
Determine the final velocity of the egg as it moves upward;
v² = u² + 2(-g)h
v² = u² - 2gh
where;
v is the final velocity
-g is negative acceleration due gravity as it moves upward
v² = 6² - 2(9.8 x 0.5)
v² = 26.2
v = √26.2
v = 5.12 m/s
The impulse applied to the egg is the change in linear momentum;
J = ΔP
ΔP = mu - mv
ΔP = m(u - v)
ΔP = 0.06(6 - 5.12)
ΔP = 0.053 kgm/s
Therefore, the impulse experienced by the egg is 0.053 kgm/s.
