Where do you weight more on top of Mt. Everest (Highest Mt. in the world) or at the beach
They are the same
Mt Everest
The beach
Not enough information
You weigh slightly more at the beach than on top of a mountain, because at the beach, you're closer to the center of the Earth.

According to Newton's second law equation, what is the relationship between net force applied and the acceleration of the object
Acceleration is inversely proportional to the net force
if acceleration goes up forces goes down
if acceleration goes down mass goes down
Acceleration is directly proportional to the net force
Answer:
Acceleration is directly proportional to the net force
Explanation:
The net force acting on an object is given by :
F = ma
Where
m is mass
and
a is acceleration
It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).
Neon has 10 electrons; two in the inner level and 8 in its outermost level. Will neon form bonds with other atoms?
Answer:
no
Explanation:
this is because its valency shell is full so it wont want any other electrons in its valence shell.

A child pushes a 2.2kg swing that is initially at rest. The net force on the swing over time is shown below. What's the swings speed at t= 40ms
Answer:
The answer is "[tex]\bold{0.36363 \ \frac{m}{s}}[/tex]"
Explanation:
Please find the attached file of the complete question:
Given:
[tex]m= 2.2 \ kg\\\\t= 40 \ ms[/tex]
Using formula:
[tex]\to F=ma[/tex]
[tex]= 2.2 \ (a)\\\\= 2.2 \ \frac{dv}{dt}[/tex]

What will happen in the next moment for the girl on the swing?
1.Fill in wether quantities will increase, decrease, or stay the same.
2. Support your answer in the table below
Answer:
Increase, same, same
Explanation:
As wavelength decreases, frequency and energy _________________;
a) increase b) decreases c) remain the same
Answer:
Increase
Explanation:
The best way for me to visualize the relation between wavelength, frequency, and energy is to think about actual ocean waves. Wavelength is a measure of the distance between two equivalent points on consecutive waves (think wave peak to wave peak). Lets say you are building a sand castle and want to see how many waves hit your castle over a period of 10 seconds. If the distance between each wave is 10 ft and the wave is traveling at 1 foot per second then you will only have one wave hit your castle. If the wavelength is 1/2 that (5 ft) then you will have 2 waves hit your castle in the same amount of time. This is the same concept behind waves in physics. The smaller the distance between each wave, the more waves and therefore more energy that will be delivered.
An 80 kg skier stands at the top of a 40-meter slope. She then skis down the slope. What is her approximate speed at the bottom of the slope if friction is negligible and her kinetic energy is 31360 J?
Thank you for that information. If we know her mass and kinetic energy, then we don't need any of that other business about the height of the slope, her skiing ability, the friction of the snow, what she uses to wax her skis, the color of her parka, or what she had for lunch at the chalet. The mass and kinetic energy are enough to answer the question.
Kinetic Energy = (1/2) · (mass) · (speed)²
31,360 J = (1/2) · (80 kg) · (speed)²
speed² = (31,360 J) / (40 kg)
speed² = 784 m²/s²
speed = 28 m/s

What is Newton's Second Law?
1.The attraction between objects
2.An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force
3.An object's acceleration depends on its mass and on the net force acting on it.
4.For every action there is an equal and opposite reaction
Answer:
An object's acceleration depends on its mass and on the net force acting on it.
Explanation:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Answer:
3.An object's acceleration depends on its mass and on the net force acting on it.
the force required to lift a load of 800 Newton by using a Lever having a mechanical advantage of 1.6 is
Answer:force required to lift the load = 500N
Explanation:
Mechanical advantage for a lever is given by the formulae
= force output/force input
or
Mechanical Advantage = Load / Effort
where
Force output / Load= 800 N
mechanical advantage = 1.6
Force input / Effort =??
Force input= Force output /Mechanical advantage
= 800N / 1.6
=500N
OR
Effort = Load/ Mechanical Advantage = 800/ 1.6 = 500N

What is the only part in our body we do not stretch?
Answer:
The quadriceps consists of four muscles: the skinny rectus femoris and the three huge “vasti” — vastus lateralis/intermedius/medialis. The vasti are only elongated by knee flexion, which is limited to about 120˚ when the calf hits the hamstrings. The vasti cannot be stretched strongly.
Answer:Masseter and temporalis
Why it’s unstretchable: The jaw can only open so far.
Why it’s a dang shame: Jaw tension is epidemic, and trigger points in these muscles cause a wide array of strange face and head pains, including toothaches, headaches, and earaches.
