The complete statement is 

As a solid element melts, the atoms become more separated and they have less attraction for one another. 

Let me explain to you how this happens. In solid phase. Its molecules are arranged in a very compact manner that is why it takes a definite shape and volume. When it is heated, the kinetic energy of the molecules increases. This is characterized by more frequent collisions. The rise in temperature causes the molecules to move rapidly by vibrating. When it reaches an amount of energy that causes the solid to change phase, this is called the latent energy. The molecules break their form and move farther away from each other until it resembles that of a liquid melting. At this point, the molecules would have lesser attraction because of the distance between them.

What is the acceleration of the the object during the first 4 seconds?
AVprozaik [17]

Answer:

Velocity (m/s) over time (s) graph

Velocity (m/s) over time (s) graph

We could write out our average acceleration as:

a = Δv/ Δta=Δv/Δta, equals, Δ, v, slash, Δ, t

a = (15 m/s - 0 m/s) / 0.2 seconds

a = 15 m/s / 0.2 seconds

a = 75 m/s / second

Explanation:

What this formula is telling us is that if we know the acceleration of an object, and the ... we can plug in our acceleration of 12.5 m/s2 for a, and 4 seconds for t.

A pair of oppositely charged parallel plates is separated by 5.38 mm. A potential difference of 623 V exists between the plates.
Salsk061 [2.6K]

Answer:

115799.256V/m

Explanation:

Given V = 623v, d = 5.38mm = 0.00538m

Strength of electric field E = V/d

E = 623/0.00538

= 115799.256V/m

A machine exerts a 100 N force to the right over a 5.00 meter length in 4.00 seconds. Calculate the power output of this machine
bixtya [17]

125 W is the power output of this machine.

Answer:

Explanation:

Power is defined as the amount of work done on the system to move that system from its original state within the given time interval. So it can be determined by the ratio of work done with time interval. As work done is the measure of force required to move a system to a certain distance. Work done is calculated as product of force with displacement.

So in the present case, the force is given as 100 N, the displacement is given as 5 m and the time is given as 4 s, then power is

Power = \frac{Work done}{Time}

As Work done = Force acting on the machine × Displacement

So Power = \frac{(Force * Displacement)}{Time}

Power = \frac{(100*5)}{4}=125 W

So, 125 W is the power output of this machine.

Read each scenario and then answer the question scenario a 120 J of work is done in 6 seconds Scenario b 160 J of work is done i
Zielflug [23.3K]

Answer:

all scenarios are using the same power

Explanation:

we know that power is defined as P(Watts)=W(Joules)/t(seconds).

When applying this formula to each of the scenarios we find:

\frac{120J}{6s}=\frac{160J}{8s}=\frac{200J}{10s}= 20W

Done
