Force (in newtons) = mass (in kg) x acceleration (m/sec)
Therefore Force = 3kg x 5m/s ==> 15 newtons
----------------------------------
75 newtons = m x 10 ==> 7.5kg
I believe...?
Answer:
mind the angle that the ball is at and subtract the answer from where the goal post is. You probably know that but my brain cant function what the answer is.
The examples of levers are seesaw, door and corkscrew
Answer: Option A, B, and C
<u>Explanation:</u>
A simple machine which is capable of rotating or moving with respect to a fixed point at the center of mass is termed as lever. Lever is made up of a rigid rod which acts as the beam or the object on which the effort can be applied based on the load and a fixed hinge like thing named as fulcrum or the center of mass.
The fulcrum will be fixed and the beam will be rotating or moving with the support of fulcrum at the center for given load or effort. So among the given options, ramp is not falling under the categories of lever as door also have a fulcrum. But the ramp is only an inclined plane without fulcrum. But the Seesaw, door and the corkscrew has both fulcrum and beam which confirms them falling in the category of lever.
