Answer:
V= 6.974 m/s
Explanation:
Component( box) weight acting parallel and down roof 88(sin39.0°)=55.4 N
Force of kinetic friction acting parallel and up roof = 18.0 N
Fnet force acting on tool box acting parallel and down roof
Fnet= 55.4 - 18.0
Fnet=37.4 N
acceleration of tool box down roof
a = 37.4(9.81)/88.0
a= 4.169 m/s²
d = 4.90 m
t = √2d/a
t= √2(4.90)/4.169
t= 1.662 s
V = at
V= 4.169(1.662)
V= 6.974 m/s
All forms of matter are comprised of atoms. Wind in itself is the movement of particles(air). Wind does not have particles since it is an action and not a form of matter.
Answer:
it has 3 electrons. brainliest please
Newton's Second law of motion is
F = m * a ( force = mass * acceleration).
So if a is constant then a = F 1 / m1 and a = F2 / m2 then
F1 /m1 = F2 / m2 and if m1 > m2 then
F1 must be greater than F2.
Answer is C.
