Answer:
F = -11199.63 N
Explanation:
given,
mass of the brick = 12 Kg
height of the fall, h = 1.9 m
thickness of the carpet = 2 cm = 0.02 m
average force = ?
velocity of brick just before hitting mat
v = 6.11 m/s
velocity of brick just before hitting ground= 6.11 m/s
final velocity = 0 m/s
using equation of motion for acceleration calculation.
v² = u² + 2 a s
0² = 6.11² + 2x a x 0.02
a =-933.3025 m/s²
now, average force is equal to
F = m a
F = 12 x (-933.3025)
F = -11199.63 N
negative sign represent the decelerating force.
It’s 10 joules. W=FD, W=5•2=10
Answer:
64 ohms =R
Explanation:
R is directly proportional to V
R is inversely proportional to I(Current
Sorry don’t know hope you gave the answer to your questions
Answer:
<em>The less mass an object has, the </em><u>less</u><em> its gravitational [force.]</em>
Explanation:
Newton's Law of Gravity states that 
. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em> 
. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em> !
I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?
