Answer:
Transferred from one atom to another
Explanation:
In a binary ionic compound, the electrons are transferred from one atom to another, thus forming positive and negative charges on the respective atoms involved, and thereby creating electrostatic forces which thus form the ionic bond.
Answer:
F₁ = 499.61 N , this is the force that Bubba support
Explanation:
The trunk is in equilibrium with the two forces applied by man, let's use the equilibrium relation
let's set a reference frame at the extreme left and assume that the counterclockwise rotations are positive
Let's write the expression for the translational equilibrium
subscript 1 is for Bubba's mass and subscript 2 for his partner
F₁ + F₂ -W = 0
F₁ + F₂ = W
the expression for rotational equilibrium
∑ τ = 0
F₁ 2.2 + F₂ (6.2-0.9) - W 6.2/2 = 0
2.2 F1 + 5.3 F2 = 3.1 W
let's write our system of equations
F₁ + F₂ = W
2.2 F₁ + 5.3 F₂ = 3.1 W
we solve for F₁ in the first equation and substitute in the second
F₁ = W-F₂
2.2 (W- F₂) + 5.3 F₂ = 3.1 W
F₂ ( -2.2 +5.3) = W (3.1 - 2.2)
F₂ = 704 0.9 / 3.1
F₂ = 204.39 N
This is the force that the partner supports
we look for F1
F₁ = W-F₂
F₁ = 704 - 204.39
F₁ = 499.61 N
This is the force that Bubba support
Answer: 45000 m/s^2
Explanation:
First, we know:
Bullet's Initial Velocity (Vo) = 0 m/s
Distance Travelled (D) = 1 m
Final Velocity (Vf) = 300 m/s
We need to know the bullets acceleration to reach the final velocity on that distance. Because the bullet stars from rest, his Initial Velocity is equal to zero.
We dont know on how much time it takes for the bullet, but we know the acceleration on the barrel is constant.
We can use the following equation for this
Because Vo is zero, the equation simplify, so we have.
Searching for the accelaration we obtain
Changing values
This is the acceleration needed to reach the velocity at the end of the barrel.
Answer:
Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.
Idk if this helps but plz mark brainliest if it does
Answer:
Newton gives us force
F=-G*M*m/R^2
Divide by the mass of the object to get acceleration
a=F/m = GM/R^2
You are solving the distance where the force from the moon equals the force from the Earth -
a= G*(mass of earth)/R^2 - G*(mass of moon)/(384400000-R)^2=0
Or in other words
G*(mass of earth)/R^2=G*(mass of moon)/(384400000-R)^2
Divide by G*(mass of the moon) and multiply by R^2 to get terms on both sides
G*(mass of earth)/(G*(mass of moon))=R^2/(384400000-R)^2
Since the mass of the moon and earth are fixed, the left side is a number
81.3 = R^2/(384400000-R)^2 → R^2/(384400000-R)^2–81.3 = 0
simplify
R/(384400000-R) = 9.01665
R=346024000 = 346,024 km.
