Answer:
Evaporation
Explanation:
Evaporation is a form of mass tranfer phenomena where by water are moved from the earth surface into the atmosphere as vapours,it is path of the water cycle a decription of the path moved by land water until it turns into rain, humidity,air and temperature are factors that influence evaporation though evaporation can happen at all temperature
==> Object A travels for 60 seconds before Object B starts out.
==> Object A moves at 2 m/s.
==> So Object A has a lead of 120 m when Object B starts out.
==> Object B moves at 3 m/s . . . 1 m/s faster than Object A.
==> So Object B catches up on Object A by 1 m every second.
==> Object B closes up Object A's lead of 120 m in <em>120 seconds</em>.
-- Gravity adds 9.8 m/s to the downward speed of any object, every second ... as long as there are no other forces messing with it.
-- In 0.6 sec, gravity added (0.6x9.8)= 5.88 m/s to the downward speed of this ball.
-- This ball didn't start from zero. You threw it down with an initial speed of 1 m/s. So after 0.6 sec, with the help of gravity, its speed is
(1) + (5.88) = 6.88 m/s .
Pick choice-C .
Notice that we don't care how high it was off the ground when you threw it, just as long as it was high enough to keep falling for 0.6 sec without hitting the ground.
The air inside the Tyre causes pressure because the particles bump into each other and cause pressure the more they bump into each other or their container the higher the pressure is.<span />
Answer:
option a is correct
net force = 28.7 N and 70º
Explanation:
given data
first force= 17.0 N
angle = 58.0º
2nd force = -19.0 N and 12.5 N
to find out
magnitude and direction net force
solution
we know here 1st force is at angle 58.0º is 17 N
so here x component of force is F1 cosθ and y component of force is F1 sinθ
so 1st force
x component of force = F1 cosθ = 17 cos(58) = 9.0086 N ...............1
y component of force = F1 sinθ = 17 sin(58) = 14.4168 N ..............2
and 2nd force
x component of force = -19 N .................3
y component of force = 12.5 N ..................4
so net force is
net force = √(Fx²+Fy²)
net force = √((9-19)²+(14.41+12.5)²)
net force = 28.7 N
and
magnitude
tanθ = Fy / Fx
tanθ = 26.92 / 10
θ = 70º
so option a is correct
