You apply a 56.3N force to a 4.2Kg cart towards the right. The cart accelerates towards the right at a rate of 0.8m/s2. What is

the magnitude, in Newtons, of the net frictional force (the sum of the only other forces, besides the 56.3N one you apply)? Please enter only a numerical answer, no units necessary.

Answer:

52,94N

Explanation:

Frictional force is the opposing force that is created between two surfaces that try to move in the same direction or that try to move in opposite directions. The main purpose of a frictional force is to create resistance to the motion of one surface over the other surface.

Calculation:

Le the value of frictional force be Fk, therefore acceleration a = (F- Fk)/m

where :

F is the applied force

m the mass of the cart

a = (F- Fk)/m = 0.8

F - Fk = 0.8m

Fk = F - 0.8m

Fk = 56.3 - (0.8×4.2)

Fk = 52.94 N

The magnitude, in Newtons, of the net frictional force is therefore 52.94N

The work done on a box is 532 joules. The force applied to the box was 48 N. What was the displacement of the box? *
Semenov [28]

Explanation:

Work = force × displacement

532 J = 48 N × d

d ≈ 11 m

In a circuit, energy is transferred to a charge.<br> Where is this energy transferred from?
vladimir1956 [14]

Answer:

Electric current.

Explanation:

The energy result from electric current resulting from potential differences between terminals which form an Electric circuit. This energy could come from different sources like chemical, wind, light

An electric circuit is one where there is movement of electrons;this electrons acquire charge which is energy. The electrons flow due to a potential difference; you have heard water flows from a higher position to a lower one freely. The highest height is said to be at higher potential and the lower point low potential.

So it's the same with electrons.

The formular for energy on charge is Q= I × t where I is electric current and t is time.

We have discovered some exoplanets that are still forming from a nebula. How might those planets change over time?
Rudik [331]
Based on several theories made by scientists, planets are formed because of the accumulation of gases and other particles that are attracted to each other. These accumulated gases form into clumps and eventually the clumps get bigger and turn into a big orbital mass. The exoplanets may experience change over time through the observance of its orbit in a particular axis, and if there are other debris that might affect the planet's continuous growth.
