To find a change from weight to mass, one must divide weight by gravity (represented by 9.8 m/s².) Thus, the equation will be 24.5 N divided by 9.8. This will equal 2.5 N.
Answer:
A star uses fusion as an energy source by building larger atoms from smaller atoms.
Explanation:
Nuclear fission and fusion are two processes at which an atomic nucleus is changed to produce energy. Fission is the process splitting heavy atomic into lighter atomic nuclei.
So, fusion is the combination of smaller atoms to form larger atoms and star uses this as source of energy.
Fusion is the process at which light atomic nuclei are merged or fused together to form heavier nuclei.
The energy source for all stars is nuclear fusion. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom.
Well gravity is always a factor on the friction of objects.
Answer:
F = 591.8 N
Explanation:
Force on a moving charge in constant magnetic field is given as
so we can say
here we know
now we have
Now concentration of Sodium ions is given as
total volume of blood = 110 cc
now total number of ions is given as
now total force on the hand is given as
Answer:
Force of kinetic friction, Fk = 6N
Explanation:
Given the following data;
Coefficient of kinetic friction, μ = 0.2
Normal force, Fn=30N
To find the Force of kinetic friction;
Mathematically, the force of kinetic friction is given by the formula;
Fk = μFn
Where;
- Fk represents the force of kinetic friction.
- μ represents the coefficient of friction.
- Fn represents the normal force.
Substituting into the equation, we have;
Fk = 0.2*30
Fk = 6N
Therefore, the force of kinetic friction is 6N.
