Answer:
The formula for force according to Newton's second law of motion is F=ma or force for an object to move is equal to mass times acceleration.
Acceleration or average acceleration defined as change in velocity per time.
F=ma
F=1.2x10³kg*(20m/s)(1/5s)=4.8x10³ Newtons
Explanation:
fthat's not the answer then i'm sorry
Given data;
Fn = 10 N
Fs = 7 N
Fe = 4 N
force in X direction (Fx) = 4 N
force in Y direction (Fy) = 10-7 = 3 N
Net force (Fnet) = Sq.root[(Fx)² + (Fy)²]
= Sq root [ 4² + 3² ]
= 25 N
<em> Net force acting = 25 N</em>
The answer is C
All other statements are correct but C
Answer:
Principal quantum numbers are denoted by the symbol 'n'. They designate the principal electron shell of the atom. The positive whole number values starting from 1,2,3 and so on..
Explanation:
All orbitals that have the same value of n are said to be in the same shell (level). For a hydrogen atom with n=1, the electron is in its ground state; if the electron is in the n=2 orbital, it is in an excited state. The total number of orbitals for a given n value is n2.
C. 340
Frequency is the number of wavelengths per second and since the length is 0.5 you multiply 0.5*686 and get 343.
the question not allowing for one position thus the answer is c
