Answer: 16.8 m
Explanation:
The motion of the lemming is a projectile motion, consisting of two independent motions:
- on the horizontal (x) axis, a uniform motion, with constant speed v = 2.87 m/s
- on the vertical (y) axis, an accelerated motion, with constant acceleration (downward)
The lemming lands in the water at x = 5.32 m away from the bas of the cliff, so we can calculate the time it takes to hit the water:
And now, by considering the motion on the vertical direction:
we can find the height of the cliff (h) by requiring that y(t)=0:
The tilt of Earth's axis hope this helps
The number of valence electron information on the periodic table is used to complete electron dot diagrams. One can obtain the number of valence electron information on the periodic table by determining the column number of the periodic table. The first column number has 1 as the number of its number of valence electron and so on.
Answer:
a) l = 24 cm
b) υ = 2.5 × 10⁹ Hz
Explanation:
given,
wavelength of microwave = 12 cm
length of microwave
= 2 × λ
= 2 × 12
l = 24 cm
microwave is an electromagnetic wave speed is 3 × 10⁸ m/s
v = υ λ
υ =
υ =
υ = 2.5 × 10⁹ Hz
Answer:
elastic potential energy
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.
