Solution for this problem is we will be using the following
formula:
Work done by applied force) = Force (applied) x s x cos θ
Where:
Force applied = 12 N
s = 13 m long
Angle = 17
So plugging in the values:
=>W (a) = 12 x 13 x cos 17
= 12 x 12.43196182
= 149.1835 J
Friction is the force that opposes motion.
<h3>What is friction?</h3>
The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.
1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.
2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.
3) The students repeated the investigation there times in order to ensure accuracy of the results.
4) The energy of the ball changes from potential energy at the top of the ramp to kinetic energy as it rolls down the ramp.

Answer:
A placebo refers to a substance or treatment that is often used in an experiment but does not have an actual medicinal or experimental benefit.
Explanation:
Answer:
C
Explanation:
The answer is obvious from the given figure
Answer:
If you meant 2.34, 2.34 meters = 23.4 decimeters.
Formula: multiply the value in meters by the conversion factor '10'.
So, 2.34 meters = 2.34 × 10 = 23.4 decimeters.
