Answer:
false
Explanation:
Because the sun has ultraviolet rays
Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion
First let us calculate for the angle of inclination using
the sin function,
sin θ = 1 m / 4 m
θ = 14.48°
Then we calculate the work done by the movers using the
formula:
W = Fnet * d
So we must calculate for the value of Fnet first. Fnet is
force due to weight minus the frictional force.
Fnet = m g sinθ – μ m g cosθ
Fnet = 1,500 sin14.48 – 0.2 * 1,500 * cos14.48
Fnet = 84.526 N
So the work exerted is equal to:
W = 84.526 N * 4 m
<span>W = 338.10 J</span>
Tere would be too many so there would be more fighting. Thye could overpopulate the world and destroy our stuff for example if it is a pig they can easily destory crops. We would all have to go hunting. There would also be less food so that is why they would start going out and destroying stuff.
