<span>Henry Moseley established a periodic table that arranges the elements by atomic number;The atomic number increases from left to right on the periodic table;Metalloids have the characteristics of both metals and nonmetals.</span>
3 Newtons toward the right because Newton’s second law:
F = ma
15N - 12N = ma
3N = ma
(With the right being the positive direction and the left the negative direction)
Hello
1) The work W is calculated as the product between the force F applied to the cart and the distance d covered by the cart:
2) The force is the product of the mass m of the cart and its acceleration a:
If we use this into the formula of the work, we get
3) The cart is moving by accelerated motion. For this kind of motion, we have the following relationship:
where
and
are the final and the initial velocity of the cart.
Re-arranging we have
4) Therefore, we can subsitute
into the original formula of the work, and we get
Answer:
Explanation:
The 3 kg box will have a downward force of its weight (Mg) and a balancing upward force of the normal force from the table. It will have a horizontal force T pointed towards the hanging mass side from the connecting cable.
The 2 kg hanging box will have a downward force of its weight (mg) and an upward force T from the connecting cable
2,450 Joules, kinetic energy is 1/2 mass x velocity squared.
