Explanation:
A 3500 N is force is applied to a spring that has a spring of constant of k= 14000 N/m. How far from equilibrium will the spring be displaced?
Answer:
the spring be displaced by 25.0 cm
Explanation:
The computation is shown below:
As we know that
F= -K × x
So,
[tex]x = \frac{-F}{K}[/tex]
Now
[tex]x = \frac{-3500}{14000} \\\\[/tex]
= -0.250m
= 25.0 cm
Hence, the spring be displaced by 25.0 cm
Which of the following describes a reference point?
A. The location of an object before its motion begins
B. The center point of a grid
C. The point at which the direction of motion changes
D. The position of an object after its motion has stopped
3. Which of the following is determined by the
force of gravity?
A weight
B momentum
C mass
D distance
Answer:
A) weight is determined by the force of gravity.
Answer:
A weight
Explanation:
The answer is weight. That's why someone would weigh more on a different planet, because the planet would have a higher/lower force of gravity.

Which type of earthquake waves are responsible for most of the damage caused by an earthquake? Why?
please helppppp its due tomorrow
Answer:
Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Answer:
surface waves
Explanation:

32. Increasing the amplitude of a sound wave produces a
sound with
1. lower speed
2. higher pitch
3: shorter wavelength
4. greater loudness
Answer:
4
Explanation:
because amplitude of a sound wave is related to loudness of the sound, so the higher the amplitude, the louder the sound
hope this helps

How does an increase in thermal energy affect the kinetic energy of the particles in each state of matter
Explanation:
when there is an increase in thermal energy, the kinetic energy if the matter increases as well.

is boiling water in a kettle on a stove kinetic or potential energy?
Answer:
Boiling a kettle is an example of both thermal and kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object.
it's kinetic!
As Clinton walks he pushes his shoe against the track.
Which of the following best describes the reaction force to Clinton's shoe pushing against the track?
OA. The track pushes back on Clinton's shoe with the same force.
ОВ.
The track pushes in the same direction as Clinton's shoe with the same force.
OC. The track pushes against gravity with the same force.
The track pushes in a different direction with a different force.
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.
pls help, i really dw fail :(
Answer:
Using the Newton equation
V²=U² +2as
Given; V=9.2m/s U = 0m/s( because it starts from rest)
S=26.2m.
9.2²=0²+2(26.2)a
a =9.2²/2(26.2)
a=84.6/52.4
a=1.60m/s²
Answer:
2.A

While standing at home plate, a batter swung a 2.5kg bat at 2.5 m/s toward an incoming mass. The mass was a 0.4 kg blob of clay, thrown toward the batter at 26 m/s, which stuck the the bat in an inelastic collision. What velocity of the velocity of the bat and blob of clay (which are stuck together) after the collision? Help fast will give brainliest
Show work
Answer:
5.74 m/s
Explanation:
m1v1+m2v2=(m1+m2)*vf
2.5*2.5+0.4*26=(2.9)vf
16.65=2.9vf
vf=5.74 m/s

Do you think we might have problems with not enough water to supply our needs (water scarcity) in the
ture? Why or why not? If you answered yes, what might the causes be?
Answer:
Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution. This was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] Two-thirds of the global population (4 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world's largest cities experience water scarcity.[5]
