Answer:
a. active volcanoes river valleys feeding into surface lakes of liquid water surfaces with very few impact.
Explanation:
Answer:
63.36 kJ
Explanation:
Potential energy (PE) is the energy stored within an object, due to the object's position, arrangement or state.
Since the Boulder is now on a height , it has a potential energy
<em>Potential Energy = mass * gravitational acceleration * height</em>
(Assume the gravitational acceleration = 10ms⁻²)
Answer:
Refraction
Explanation:
Refraction, meaning passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped it help..
Answer:
initial velocity (u) = 200m/s
final velocity (v) = 350 m/s
time (t) = 15s
acceleration (a) = ?
NOW,
a=v-u/t
a= 350-200/15
a= 50/15
a= 3.3333
Explanation:
it's too easy just u need to understand the question . and go according to it's content .
main thing to memorize is it's simple formula.
