Answer:
a= g = - 9.81 m/s2.
The following equations will be helpful:
a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad
When you substitute the specific acceleration due to gravity (g), the equations are as follows:
g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd
If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:
g = vf /t d = 1/2 gt2 vf2 = 2gd
The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.
hope this info helps you out!
It depends on the angle of the earth, and our point of view. A full moon would occur if we were to be right in front of it.
Answer:
Answer is C.
Explanation:
To calculate the IMA for a wheel and axle, find the ratio of the larger radius to the smaller radius:
IMA = R/r
IMA = 9/3
IMA = 3
Elements have balanced protons and electrons, so the answer is 88.
Explanation:
4.he invented the atomic model with all different electrons proton and neutrons
5. this was important as this was developed and is still used in the modern day
