Answer:
Einstein's 1915 general theory of relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. The scientist proposed that objects such as the sun and the Earth change this geometry.
Explanation:
Answer:
Final velocity will be 7.31 m/sec
Explanation:
We have given applied force F = 150 N
Mass of the object m = 11 KG
Distance traveled by the object s = 2.5 m
Coefficient of kinetic friction 
Acceleration due to gravity 
So frictional force applied on the object 
So net force = 150-32.34 = 117.66 N
As work done us equal to 
So work done = 
Now according to work energy theorem work done is equal to change in kinetic energy
So 
v =7.31 m/sec
So velocity final velocity will be 7.31 m/sec
All of it until it breaks down into 1 piece
Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals that scientists describe as elliptical. It is one of Kepler's laws. The sun is the focus of all the planets. The correct answer is D.
<h2>Answer</h2>
option D)
2.4 seconds
<h2>Explanation</h2>
Given in the question,
mass of car = 1200kg
speed of car = 19m/s
Force due to direction of travel
F = ma
= 12000(a)
Force to due frictional force in reverse direction
-F = mg(friction coefficient)
= -12000(9.81)(0.8)
<h2>
-mg(friction coefficient) = ma </h2>
(cancelling mass from both side of equation)
g(0.8) = a
(9.81)(0.8) = a
a = 7.848 m/s²
<h2>Use Newton Law of motion</h2><h3>vf - vo = a • t</h3>
where vf = final velocity
vo = initial velocity
a = acceleration
t = time
0 - 19 = 7.8(t)
t = 19/7.8
= 2.436 s
≈ 2.4s
