1.3s
Explanation:
Given parameters:
Height = 1.4m
Gravity on moon = 1.67ms⁻¹
Unknown:
Time for feather to fall = ?
Solution:
To solve this problem, we are going to use one of the motion equation that relates time, gravity and height.
H = ut + 
Sine the body was dropped from rest, initial velocity is zero;
H = height
u = initial velocity
t = time
g = acceleration due to gravity
since u = 0;
H = 
1.4 =
x 1.67 x t²
t = 1.3s

Answer:
If a body is constantly accelerating the graph would be one-quadrant
an element can make a molecule. so technically yes.
Answer: Electrons move around the nucleus in fixed orbits of equal levels of energy
Explanation:
The statement that accurately represents the arrangement of electrons in Bohr’s atomic model is that the electrons move around the nucleus in fixed orbits of equal levels of energy.
It should be noted that the electrons have a fixed energy level when they travel around the nucleus in with energies which varies for different levels.
Higher energy levels are depicted by the orbits that are far from the nucleus. There's emission of light when the electrons then return back to a lower energy level.

The likelihood of reaching 40 miles per hour is very slim. Several factors are related to how quickly somebody can run, which is why only one person has ever run 28 miles per hour.Catch a sprinter smashing a speed record and they look like they could keep up with a car chase. 40 MPH: The fastest speed humans can run. The current fastest human in the world is Usain Bolt, who can run at nearly 28 miles per hour.Steve in Davis, Calif. So far, the fastest anyone has run is about 27½ miles per hour, a speed reached (briefly) by sprinter Usain Bolt just after the midpoint of his world-record 100-meter dash in 2009.
