Answer: I think it’s D i really hope this helps!!!!
Explanation:
The correct answer would be to express large and small numbers.
The planet MARS is visible without a telescope on many clear nights. The planets JUPITER, MERCURY, VENUS and SATURN are also viewable without the aid of magnification.
Answer:
v = 17.15 m/s
Explanation:
given,
angle of ramp = 17.0°
length of ramp(l) = 30 m
height of the ramp =
h = 15 m
using energy of conservation
v = 17.15 m/s
speed of block reaching at the bottom = v = 17.15 m/s
