This question is asking: Why does gravity occur? why will your notebook get pulled towards you?
Answer: 20.4m
Explanation:
Mass = 0.145kg
Initial velocity, Vi =20m/s
Initial kinetic energy K =1/2mv^2
Initial potential energy Ui = mgx = 0joules
: From conservation of energy,
Uf + Kf = Ui + Ki ( where f represent (final) )
Thus
mgXf + 0 = 0+1/2 mv^2
Xf = Vi^2/ 2g
= (20m/s) ^2/ 2(9.81m/s)^2
=20.4m
0.12244898 is the value obtained when solving the given.
<u>Explanation:</u>
Given:
3 times 10 to the 8th power can be expressed in equation format as (3 times symbolizes ‘multiplication’ then it is to the tenth power of 8)
2.45 times 10 to the 9th power can be expressed in equation format as (2.45 times symbolizes ‘multiplication’, then it is to the tenth power of 9)
Asked to find the solution when dividing the above,
When the tenth power of any value goes from denominator to numerator and vice-versa, presents in opposite sign to that it possess (like when ‘ ' goes to numerator changed as ' ').
Now by solving the above equation, we get
Answer:
5.39 N
Explanation:
Given
the string has a mass of 47.3 g and a length of 0.93 m.
mass holder (M_holder = 50.0 g) that carries a weight of 5.00x10^2 g.
g= 9.80 m/s^2
By the FBD we write
Tension in the string = (M_holder+mass of weight)×g
= [(50.0+5.00×10^2)×10^-3×9.80] N
= 5.39 N
