A student pulls a 2.0-kg object to the left with a force of 30 N, while another student is pulling against the object in the opp
alex41 [277]

Answer:

5 m/s2, left

Explanation:

We can solve the problem by applying Newton's second law of motion, which  states that:

\sum F=ma

where:

\sum F is the net force acting on an object

m is the mass of the object

a is its acceleration

In this problem, we have:

\sum F=30 N - 20 N = 10 N (to the left) is the net force on the object

m = 2.0 kg is the mass

So, the acceleration is:

a=\frac{\sum F}{m}=\frac{10}{2.0}=5.0 m/s^2

in the same direction as the force (left).

Explain in detail what specific factors affect the momentum of a bicycle going down hill.
Crazy boy [7]

Mass and velocity are the two terms which affect momentum of a bicycle going hill down.

Explanation:

As we know that Momentum describes the motion of an object. It is the combination of the objects mass and velocity.

So, obviously with no doubt mass and velocity are the two terms which affect momentum.

Momentum(p) = Mass(m) * Velocity(v)

The momentum also depends upon the mass and speed of the object.

More the mass of the object more is the momentum.

Depending upon the gravity and bicycle's motion speed momentum varies.

Bicycle moves faster the down hill if it moves with some speed as it has lesser mass the momentum also will be less.

With thermodynamics, one cannot determine ________. Question 6 options: the speed of a reaction the direction of a spontaneous r
pantera1 [17]

Answer:

A.  the speed of a reaction

Explanation:

The thermodynamic aspect of a reaction will show you the energy needed for a reaction to occur. If the energy difference(ΔG)  is positive, which means the reaction is absorbing energy and it called endothermically. The opposite will be an exothermic reaction that will release energy, which means it doesn't need energy and the energy difference (ΔG) will be negative.  

Thermodynamic can be used to determine a few things of a reaction, like the direction of the reaction, the extent, or temperature in which the reaction is spontaneous. But thermodynamic not used to find the speed of a reaction.
