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:
The magnitude and direction of the centripetal acceleration will be:
m/s² (towards the center of the circle).
Explanation:
Given
Using the formula to determine the centripetal acceleration
m/s²
As the truck is moving in a circle, therefore the direction is towards the center of the circle.
Hence, the magnitude and direction of the centripetal acceleration will be:
m/s² (towards the center of the circle).
Answer:
0.001 liter
Explanation:
Milliliter to liter formula-
Divide the volume value by 1000.
1 ml. divided by 1,000 is 0.001.
This is the correct formula and answer.
Hope this helps!
Answer:
This question is incomplete but the completed question is below
A ray of light parallel to the principal axis of a spherical mirror passes through its _____ after reflection.
(a) focus (b) pole (c) centre of curvature (d) imaginary centre of curvature
The correct option is (a)
Explanation:
After reflection, a ray of light will usually appear to diverge after they hit a spherical mirror, extending behind the mirror to meet at a point (called the focus or focal point) between the pole and the centre of curvature of this mirror. Hence, option a is the correct option.
Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
