Answer:
6.65m/s
Explanation:
Using the equation of motion
S = ut + 1/2gt²
S is the height of fall
t is the time
u is the horizontal velocity
g is the acceleration due to gravity
Given
S = 300 + 50
S = 350m
t = 7.8seconds
g = 9.8m/s^2
Get S
S = 7.8u + 1/2(9.8)(7.8)²
S = 7.8u + 298.116
350 = 7.8u + 298.116
7.8u = 350 - 298.116
7.8u = 51.884
u = 51.884/7.8
u = 6.65m/s
Hence the rock's horizontal velocity was 6.65m/s

Answer:
the car will slow down due to the change in speed
Answer:
There are 5 of 'em.
It's so amazing.
1. The electric eel; It can generate about 370-650 volts of electric current from it's body.
2. The electric catfish!
About 350-450volts of electric current.
3. The electric Ray.
Say no more. It can generate about 37-220volts.
4. The electric stargazer (really stargazer, lol, and you live down the sea)
About 50volts
and
5. Skate.
Just 4volts.
You know more than to be careful when you go diving in the sea.
I love your question btw. I learnt also.
if you're shopping for a rack switch, the component on the switch that tells you it can be mounted to a rack is the:
<h3>What are rack ears?</h3>
Rack ears are L-shaped objects that can be used to hold a rack switch firmly to the support walls. Rack ears are often found at the front panel of the rack which is to be mounted.
When a person purchases a rack switch and finds the rack ears there, it is a signal that the item can be secured firmly to rails. Sometimes, the rack ears also appear as extensions.
