You've given the answer, right there in your question.
The "magnitude of gravity" is described in terms of the acceleration
due to it, and you just told us what that is.
We can also notice that the figure you gave is about 0.66 of the
acceleration due to gravity on the Earth's surface. That tells us that
the distance from the Earth's center at that height is about
(1 / √0.66) = 1.23 times
the Earth's radius, so the height is about 910 miles above the surface.
Answer:
This is because we are surrounded by positive ions from electromagnetic fields generated by computers, cell phones, and other electronic devices which can impair brain function and suppress the immune system causing symptoms such as: anxiety, breathing difficulty, fatigue, headaches, irritability, lack of energy, poor concentration, nausea, and vertigo,
Explanation:
Answer:
F₂ = -7.3 N
Explanation:
Given that,
The mass of an object, m₁ = 3.7 kg
First force, F₁ = 11 N
The net acceleration of the object is 1 m/s².
We know that,
F₁+F₂ = ma
11+F₂ = (3.7)(1)
F₂ = 3.7-11
F₂ = -7.3 N
so, the other force is 7.3 N and it is acting in west direction.
a) 32.3 N
The force of gravity (also called weight) on an object is given by
W = mg
where
m is the mass of the object
g is the acceleration of gravity
For the ball in the problem,
m = 3.3 kg
g = 9.8 m/s^2
Substituting, we find the force of gravity on the ball:
![W=(3.3)(9.8)=32.3 N](https://tex.z-dn.net/?f=W%3D%283.3%29%289.8%29%3D32.3%20N)
b) 48.3 N
The force applied
![F_{app} = 36 N](https://tex.z-dn.net/?f=F_%7Bapp%7D%20%3D%2036%20N)
The ball is kicked with this force, so we can assume that the kick is horizontal.
This means that the applied force and the weight are perpendicular to each other. Therefore, we can find the net force by using Pythagorean's theorem:
![F=\sqrt{W^2+F_{app}^2}](https://tex.z-dn.net/?f=F%3D%5Csqrt%7BW%5E2%2BF_%7Bapp%7D%5E2%7D)
And substituting
W = 32.3 N
Fapp = 36 N
We find
![F=\sqrt{32.3^2+36^2}=48.3 N](https://tex.z-dn.net/?f=F%3D%5Csqrt%7B32.3%5E2%2B36%5E2%7D%3D48.3%20N)
c) ![14.6 m/s^2](https://tex.z-dn.net/?f=14.6%20m%2Fs%5E2)
The ball's acceleration can be found by using Newton's second law, which states that
F = ma
where
F is the net force on an object
m is its mass
a is its acceleration
For the ball in this problem,
m = 3.3 kg
F = 48.3 N
Solving the equation for a, we find
![a=\frac{F}{m}=\frac{48.3}{3.3}=14.6 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BF%7D%7Bm%7D%3D%5Cfrac%7B48.3%7D%7B3.3%7D%3D14.6%20m%2Fs%5E2)
The choices above are social psychology terms
that help describe the people’s actions in their everyday interaction with
people. The sentence example is:
Those computer geeks are all the same.
They
spend all day playing video games and programming their computers to serve them
breakfast. I don't think I've ever seen one reading a real book or throwing a
baseball. Why, they're almost like machines!

happens when a person applies a single group behavior or minority behavior to a
whole group ‘s behavior sharing the same characteristic.</span>
