Answer:
The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.
Explanation:
Independent
Answer:
acceleration = 22.14 m/s²
time = 2.80 s
Explanation:
given data
initial velocity = 31.0
final velocity =
time = 1.40
solution
we get here acceleration that is
acceleration =
...............1
acceleration =
acceleration = 22.14 m/s²
and
by kinematic equation of motion
v = u +at .........2
t =
time = 2.80 s
Answer:
Retina is the part of eye which is used to see things in high details
Explanation:
The energy stored in an elastic objects as a result of deformation is called elastic potential energy. The energy stored in a spring is given by :

Where
k = spring constant
x = compression or stretching in an spring
While gravitational potential energy is given by :
PE = mgh
where
m = mass
g = acceleration due to gravity
h = height from ground
So, the factor affecting elastic potential energy but not gravitational potential energy is " spring constant ".
Charge = 0.2 Ah is the correct answer...
