A control is something you don't touch/change in a exprement, a constant is the same as the control, the independent is the one the you do vhange, the dependet is the one that you observe/ use your 5 sences with.
Answer:
Explanation:
Given that
Speed ,v= 2 x 10⁵ m/s ( - y direction)
B= 0.6 T (- z direction)
The resultant force on the proton given as
F= m a
For uniform motion acceleration should be zero.
F = 0
Electric filed should be apply in the negative x direction.
A good way to determine the property of a substance would be it's boiling and melting point, its conductivity, and how hard or soft that substance is.
The average force applied by the ground on the Aeroplane is 16.664 kN.
<h3>What is Newton's second law of motion?</h3>
It states that the force F is directly proportional to the acceleration a of the body and its mass.
F =ma
Given is the mass of aeroplane, m =400 kg and the velocity v = 5000 m/s,
It takes t = 2 min to come to rest, then the acceleration will be
a = velocity /time
a = 5000/(2x60)
a = 41.66 m/s²
According to the Newton's second law of motion.
F = 400 kg x 41.66 m/s²
F = 16.664 kN
Thus, the average force applied by ground on aeroplane is 16.664 kN
