Answer:
Time moves slower and length decreases.
Explanation:
The most necessary condition to build a glacier is: <span>More snow must fall in the winter than melts in the summer.
</span><span>when More snow fall in the winter than it melts in the summer, the snow will start to accumulate on the top of the higher terrain. This accumulation will form an abundant amount of snow on higher terrain, which will fall as glacier as soon as its temperature drop.</span>
Answer:
A system of two co-axial cylindersof different diameters which rotate together is called wheel and axle example; the door knob , knob of the tap ,screw driver,water tap
We have that the maximum rank of the kangaroo is given by:
R = v0 ^ 2 sin (2θ) / g
where,
v0 = initial velocity
θ = angle of the velocity vector formed from the horizontal
g = gravity
Clearing the speed we have:
v0 ^ 2 = (R * g) / (sin (2θ))
Substituting values
v0 = root (((11) * (9.8)) / (sin (2 (21 * (pi / 180)))))
v0 = 12.69 m / s
answer
its takeoff speed is 12.69 m / s
