Answer:
μ = 0.31
Explanation:
The friction force must provide the needed centripetal force
mω²R = μmg
μ = ω²R/g = (2π/1.8)²(0.25) / 9.8 = 0.31
Answer:
W= 565.42 J
Explanation:
Given that
mass , m =20.5 kg
displacement = 5.93 m
Applied force ,F= 95.3501 N
Coefficient of friction ,μ = 0.389
We know that work done by force F is given as
W= F .d
d=Displacement
F=Force
W=Work
W= 95.3501 x 5.93 J
W= 565.42 J
Therefore the work done by applied force will be 565.42 J.
Answer
Hi,
In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.
Explanation
When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation.
Good luck!
Answer:
In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact.
