<span>Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric charge flows in a constant direction, distinguishing it from AC. A term formerly used for direct current was galvanic current.</span>
Invention is the creation of a product and innovation is when someone improves on or makes a significant contribution to an existing product.
The problem is a free fall problem as the camera drops. The vertical velocity is zero. It is the action of gravity that takes place here. To calculate the time it takes to reach the ground, we do as follows:
t = √2y/g = √(2)(70)/9.81 = 3.78 s
The velocity as it impacts the ground would be,
v = √2gy = 37.04 m/s
Hope this helps.
You get the color yellow :)
Heya!!
For calculate final velocity, lets applicate formula
<u>Δ Being Δ</u>
V = Final Velocity = ?
Vo = Initial velocity = 0 m/s
a = Aceleration = 5 m/s²
t = Time = 12 s
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The velocity after 10 sec is <u>60 meters per second (m/s)</u>
Good Luck!!
