They both move in the opposite direction in which they hit
Answer:
fluorescent bulb
Explanation:
A fluorescent bulb is what produces light.
It produces light by passing electric current through a gas to
A fluorescent lamp, is a low-pressure mercury vapor and a gas-discharge lamp that uses fluorescence to produce visible light. like the ones we see. An electric current in the gas excites mercury vapor, and that produces a short wave ultraviolet light and well that causes a phosphor coating on the inside of the lamp to glow. i tried making this sound as simple as possible.
i hope this really helps you !! thanks this and mark this as brainliest !!!
Answer:
200 K
Explanation:
0 °C = 273 K
-73°C = 273 K - 73 K = 200 K
A geologic event causes changes to the physical makeup of a particular place and occurs slowly.
Geological events are what causes numerous changes and phenomena on the Earth's surface. Examples of these events include cliff erosion, volcanic eruption, or sedimentation at a mouth of a river.
Geological processes are extremely slow. However, because of the immense lengths of time involved, huge physical changes do occur - mountains are created and destroyed, continents form, break up and move over the surface of the Earth, coastlines change and rivers and glaciers erode huge valleys.
Geological events are both classified as internal and external. This means that these events occur both in the Earth's surface and interior.
Answer:
Explanation:
h = height of the cliff
Consider upward direction as positive and downward direction as negative
Consider the motion of rock thrown straight up :
Y = vertical displacement = - h
v₀ = initial velocity = 8.63 m/s
a = acceleration = - 9.8 m/s²
t = time taken to hit the ground = 3 s
Using the equation
Y = v₀ t + (0.5) a t²
- h = (8.63) (3) + (0.5) (- 9.8) (3)²
h = 18.21 m
Consider the motion of rock thrown down :
Y' = vertical displacement = - 18.21
v'₀ = initial velocity = - 8.63 m/s
a' = acceleration = - 9.8 m/s²
t' = time taken to hit the ground = ?
Using the equation
Y' = v'₀ t' + (0.5) a' t'²
- 18.21 = (- 8.63) t' + (0.5) (- 9.8) t'²
t' = 1.2 s
