Traditional is the old way of doing stuff, Command is a system ruled by one person, Market is having buyers and sellers make economic decisions
You can reason it out like this:
-- The car starts from rest, and goes 8 m/s faster every second.
-- After 30 seconds, it's going (30 x 8) = 240 m/s.
-- Its average speed during that 30 sec is (1/2) (0 + 240) = 120 m/s
-- Distance covered in 30 sec at an average speed of 120 m/s
= 3,600 meters .
___________________________________
The formula that has all of this in it is the formula for
distance covered when accelerating from rest:
Distance = (1/2) · (acceleration) · (time)²
= (1/2) · (8 m/s²) · (30 sec)²
= (4 m/s²) · (900 sec²)
= 3600 meters.

When you translate these numbers into units for which
we have an intuitive feeling, you find that this problem is
quite bogus, but entertaining nonetheless.
When the light turns green, Andy mashes the pedal to the metal
and covers almost 2.25 miles in 30 seconds.
How does he do that ?
By accelerating at 8 m/s². That's about 0.82 G !
He does zero to 60 mph in 3.4 seconds, and at the end
of the 30 seconds, he's moving at 534 mph !
He doesn't need to worry about getting a speeding ticket.
Police cars and helicopters can't go that fast, and his local
police department doesn't have a jet fighter plane to chase
cars with.
B. True give me branliest
Answer: Change in velocity: -10 m/s, acceleration=-2.5m/s
Explanation:
The question in english is written below:
The end of a robotic arm moves to the right at 8m s. Four seconds later it moves to the left at 2m/s. What is its change in velocity and what is its change in acceleration?
We have the following data:
Initial Velocity of the robotic arm: (to the right)
Final Velocity of the robotic arm: (to the left)
Variation in time:
Firstly we have to calculate the change in velocity , which is given by the following equation:
This means the resultant velocity is to the left
Now, we can find the acceleration , given by:
This means the acceleration is also to the left, however its magnitude is always positive:
Answer:
Explanation:
Given
Electric Field Strength
Potential Difference between Plates is given by
In conducting plates a Potential difference exist between two plate which accelerate the charge when put between the conducting plates
The potential difference is given by
where E=Electric Field strength
d=distance between Plates
