Answer:
The velocity just before hitting the ground is 
Explanation:
From the question we are told that
The initial speed is 
The final speed is 
From the equations of motion we have that
Where s is the distance travelled which is the height of the cliff
So making it the subject of the the formula we have that
Where a is the acceleration due to gravity with a value 
So
Now we are told that was through horizontally with a speed of
Which implies that this would be its velocity horizontally through out the motion
Now it final velocity vertically can be mathematically evaluated as
Substituting values
The resultant final velocity is mathematically evaluated as
Substituting values
Answer:
810 mA
Explanation:
In a series circuit, the current is the same through the system, so if the current through one resistor is 810 mA, the current supplied by the source will be 810 mA.
So, the answer is 810 mA
Answer:
B. Acceleration in the direction of motion speeds you up
Explanation:
Acceleration is defined as when something gains speed. For example, when a car speeds up. Deceleration is when the car slows down, and looses speed. When defining these terms, think of a car going faster, then slowing down at a red light.
Answer:
The answer is
Explanation:
A.
Daniela had a 5 meter head start, and Leonard caught up to her at 25 meters.
brainiest would be cool
Answer:
The electron microscopes are uses the electron to produce the image of the any object.The area where the electron passes then that area appeaser white but on the other hand where the electron does not pass that area appears black.But this does not give any information about the color of light it shows only white and black areas.We also know that color is the property of photons ( light).So the microscopes does not produce color of the image.
