Answer:
Carbon
Explanation:
because carbon dioxide is the combination of element and radical whereas in air different gases can be founded and in water hydrogen and oxygen are found
Full moon!
when Earth is exactly between the Moon and Sun, Earth's shadow falls upon the surface of the Moon, dimming it and sometimes turning the surface red over the course of a few hours.
Answer:
μ = 0.109
Explanation:
Draw a free body diagram of the crate. There are four forces:
Weight force mg pulling down.
Normal force N pushing up.
Applied force P pulling at θ above the horizontal.
Friction force Nμ pushing to the left.
Sum of the forces in the y direction:
∑F = ma
N + P sin θ − mg = 0
N = mg − P sin θ
Sum of the forces in the x direction:
∑F = ma
P cos θ − Nμ = ma
P cos θ − ma = Nμ
μ = (P cos θ − ma) / N
μ = (P cos θ − ma) / (mg − P sin θ)
Given:
P = 585 N
θ = 28.0°
m = 125 kg
a = 3.30 m/s²
μ = (585 cos 28.0° − 125 kg × 3.30 m/s²) / (125 kg × 9.8 m/s² − 585 sin 28.0°)
μ = 0.109
The electric potential at that point in space is 8 v is 32uj
what is electric potential energy?
Potential energy is the energy within an object relative to its position and proximity to other objects within a field.
The electric potential of a point charge is V=kQ/rV=kQ/r , or V = k Q / rV=kQ/r . Electric potential is a scalar while the electric field is a vector. While the total electric field can be computed by adding individual fields as vectors, the voltage resulting from a collection of point charges can be calculated by adding voltages as integers.
It is decided to set the potential at infinity to zero.
but V for a point charge reduces with distance while decreasing with distance squared. Remember that the electric field E is a vector, but the electric potential V is a scalar with no direction.
The electric energy is (8×4)=32 uj
