Answer:

Explanation:

Forces can change speed of motion, the more force that's applied when you push a ball for example, the faster the ball will go. Force can also change the shape of objects by applying pressure to them too. The inertia from force can change direction, as when you let's say hit a tennis ball, it won't go perfectly straight. So all of the above are correct

A constant unbalanced force is applied to an object for a period of time. Which graph best represents the acceleration of the ob

balu736 [363]

Answer:

Here is an image attached with similar questions.

The correct answer is D where acceleration is function of time.

Explanation:

The force acting on the object is constant.

There is no change in the application of forces.

And we know that Force is the product of acceleration and masses.

Newtons second law: $F=m\times a$

Regarding mass we know that it can neither be created nor destroyed.

So in $F=m \times a$ we have two constant terms, constant divided by constant will give the same result as $a=\frac{Force}{mass}$

There is no change in acceleration $(a)$ with respect to time $(t)$ .

So the most appropriate graph where time (t) is changing on $x-axis$ but acceleration doesn't changes is D.

The graph will be similar to $y=any\ constant$ and will be horizontal to the $x-axis$ .

Option D depicts the same.

Water vapor can react reversibly with solid carbon to yield a mixture of hydrogen gas and carbon monoxide. Suppose you continual

umka2103 [35]

Answer:

Product side

Explanation:

When water vapor reacts reversibly with solid carbon to yield a mixture of hydrogen gas and carbon monoxide and we continually add more water vapor to the reaction the equilibrium of the reaction shifts to the product side.

Because gaseous water is reactant that appears in the reaction quotient expression.

$H_{2}O+ C_{s}\leftrightharpoons H_{2}_{g}+ CO$

When we add more water vapor to the reaction the product formation is increased. The reaction goes in forward direction affecting the equilibrium.

What limits the amplitude of motion of a real vibrating system that is driven at one of its resonant frequencies?

andriy [413]

To find limits of the amplitude of motion of real vibrating system that is driven at one of its resonant frequencies, Here the damping of vibrations turns the energy of vibration into internal energy.
