Answer:
W = 637 N
Explanation:
For this exercise we will use Newton's second law
F -W = m a
where F is the force, m the mass and the acceleration
in this case the force is the weight of the body and as the elevator goes at constant speed the acceleration is zero
F = W
a = 0
F = W
W = m g
W = 65 9.8
W = 637 N
Answer:
The magnitude of the electric field is 8.47 N/C
Explanation:
Given;
uniform charge density, λ = 100 nC/m³
inner radii of the cylinder, r = 1.0 mm and 3.0 mm
distance from the symmetry axis, R = 2.0 mm

Area = 2πrl
Area =2π(2 x 10⁻)l
Volume = A x d
d = Volume / Area

the magnitude of the electric field

Therefore, the magnitude of the electric field is 8.47 N/C
Low mass lives long .
Because High mass loss his energy sooner and it will die . so low mass longer live
Substract two consecutive terms of the sequence to see if there is a common difference:

As we can see, there is a common difference of -6.
Then, if a number of the sequence is given, the next one can be found by adding -6 (which is the same as subtracting 6).
Notice that the first term of the sequence is 3.
Then, the rule for the sequence is to start with 3 and add -6 repeatedly.
Therefore, the correct choice is option A) Start with 3 and add -6 repeatedly.
