Displacement=-21
Distance=39
(Sorry if this didn’t help)
I would assume gamma rays because they have the fastest moving partials out of all of them
Answer:
mass=56.12kg
Explanation:
PE=mgh
4620=m×9.8×8.4
make m subject of the formula...
m =4620/(9.8×8.4)
m=4620/82.32
m=56.12kg
Answer:
Horizontal component of velocity = 241.61 m/s
Explanation:
Given that,
Velocity of a jetliner is 245 m/s
The vertical component of the plane's velocity is 40.6 m/s, 
We need to find the magnitude of the horizontal component of the plane velocity.
The resultant velocity is given by :
Where, 
is the horizontal component of the plane velocity
So, the magnitude of the horizontal component of the plane velocity is 241.61 m/s.
Answer:
Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.
Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.
So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:
At,
t=0, v=0 m/s
t=1, v=0+10 m/s;
t=2, v=0+10+10 m/s;
t=3, v=0+10+10+10 m/s;
This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:
v = u + at
