James is trying to prove Newton's 2nd law of motion. He tries to move four different objects with different masses, shapes, and

sizes from point A to point B. The objects are a toy car, a car, a refrigerator, and a kitchen table. After some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. The object that takes the most force to move is the

The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.

Answer:

A car

Explanation:

Newton’s second law of motion states that the rate of change of linear momentum is directly proportional to the applied unbalanced force. It also gives the measure of force i.e.

F = m.a.... (1)

Where

m is the mass of body

a is the acceleration produced

In this case, James is trying to prove Newton's 2nd law of motion. He moves four object namely, a toy car, a car, a refrigerator, and a kitchen table with different masses, shapes, and sizes from point A to point B.

It is clear from equation (1), that the force depend only on the mass of body not on its shape and size.

So, the force that takes the most force to move is ''a car'' due to its more mass.

How do i find the number of leptons in an atom??
Serjik [45]

Answer:

In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.

5) A person holds a 1.7 kg bucket and lets it move down at
Elena L [17]

Answer:

12.5J

Explanation:

Given parameters:

Mass of bucket  = 1.7kg

Height  = 75cm  = 0.75m

Unknown;

Work done on the bucket by the person  = ?

Solution:

To solve this problem, we use the work done equation;

  Work done  = force x distance  = mgh

 m is the mass  

  g is the acceleration due to gravity

  h is the height

Now, insert parameters and solve ;

     Work done  = 1.7 x 9.8 x 0.75  = 12.5J

A carriage of 20 kg is pulled with a force of 35 N. How far the carriage will go
Gennadij [26K]

Answer:

2.71 m

Explanation:

Force is the product of mass and acceleration

F=m*a

Work done is the product of force and distance

Work done=F*d

In this case;

F= 35 N

Work done = 95 J

95 =35 * d

95 /35 = d

2.71 m= d
