I don't know what the question is but if its true or false then it is true.
Answer:
400N
Explanation:
If you have 2 forces (200N) and (200N) pushing an object the same direction in a one dimensional force vectors, the answer would be 400N
Answer;
At the top of group 17
Explanation;
Reactivity in chemistry deals with whether something will react with another substance. The reactivity of an element can be predicted based on its location on the periodic table.
The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive nonmetals. This is because they all have one empty space in their valence electron shells. Of the halogens, fluorine's empty space is closest to the positively charged nucleus. This means it pulls harder on another atom's electrons to fill that empty space.
Explanation:
here u = 50m/s
v = 60m/s
t = 58 s
then a = (60-50)/58 m/s2
= 0.17m/s2
now s= ut+1/2at2
so , 50×58+0.5×0.17×(58)^2 m
= 3185.94 m
= 3.18 km
Answer:
14.69
Explanation:
The circle of radius R = 11.0m
Force f = 3 times her Weight
= 3W = 3mg
Then the net force acting on her
F = W + F(centripetal)
= mg + mv²/r
= Mg + mv²/r = 3mg
Then her speed is going to be
V = √2gr
Where g =9.81m/s²
R = 11.0
When we put these values into the formula we get:
V = √2x9.81x11.0
V = √215.82
V = 14.69
