It has to be the last one because whenever lights are turned on it decreases because all lights are on at the same time. It's good to just have one light on. It doesn't use as much electricity.

Suppose the carts collided on a surface that had a slight incline to it. Would you expect the momentum to be conserved

lesantik [10]

Momentum is conserved when carts are collided on a slanting plane.

To find the answer, we need to know about the conversation of momentum.

<h3>What's the conversation of momentum?</h3>

Conservation of linear momentum says the total momentum before the collision and after the collision remains the same.
Mathematically, m1u1+m2u2 = m1v1+m2v2

<h3>How is the momentum conserved when collision occurs on a slanting plane?</h3>

On a slanting plane, the velocity has two components,

horizontal component
horizontal component Vertical component

So, its momentum has also similar two components.
The momentum is conserved along horizontal direction and vertical direction separately.

Thus, we can conclude that the momentum is conserved when carts are collided on a slanting plane.

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.

"How do changes in voltage or resistance affect current in an electric circuit?"

kicyunya [14]

We can answer the question by looking at the Ohm's law, which gives us the relationship between voltage (V), current (I) and resistance (R) of a circuit:
$V=IR$
equivalently, we can rewrite it as
$I= \frac{V}{R}$

by looking at the equation, we can make the following observations:
1) The current is proportional to the voltage: therefore, if the voltage increases, the current increases as well; if the voltage decreases, the current decreases too.
2) The current is inversely proportional to the resistance: if the resistance increases, the current decreases, and if the resistance decreases, the current increases.

One side of a triangle is increasing at a rate of 5 cm/sec and a second side is increasing at a rate of 7 cm/sec. If the area of

Vanyuwa [196]

Answer:

The rate of angle is 26.25 rad/sec.

Explanation:

Given that,

First side of triangle a= 20 cm

Second side of triangle b= 50 cm

One side of a triangle is increasing at a rate = 5 cm/sec

Second side is increasing at a rate = 7 cm/s
