Metals, Metalloids, and Nonmetals These elements can be classified as metals, nonmetals but metalloids ,Metals are good conductors of heat and electricity, and are malleable they can be hammered into sheets and (ductile- they can be drawn into wire.)

Answer:

The value of $\dfrac{dU}{dM}$ is $6\times10^{-29}\ J/unit$ .

Explanation:

Given that,

Number $N=10^{8}$

Energy difference = 6\times10^{-21}\ J[/tex]

Temperature T =300 K

We need to calculate the value of $\dfrac{dU}{dM}$

We know that,

$\dfrac{dU}{dM}=\dfrac{energy\ difference}{Change\ in\ number\ of\ system}$

$\dfrac{dU}{dM}=\dfrac{6\times10^{-21}}{10^{8}}$

$\dfrac{dU}{dM}=6\times10^{-29}\ J/unit$

Hence, The value of $\dfrac{dU}{dM}$ is $6\times10^{-29}\ J/unit$ .

Net force and direction answer

Contact [7]

Answer:

7. Net force: 14 N

Direction: Right

8. Net force: 360 N

Direction: Right

Explanation:

For Nm 7 the most force is on the right side so it has more power then left side and so its gonna pull towards the right side cancelling the force on the left. So it becomes 26-12 N = 14N

For Nm 8 all the force is on the right side so they add up.

According to Newton's 2nd law, when something is traveling 50cm with changing forces (in Newtons), why does acceleration = 1/t^2

creativ13 [48]

The relation between acceleration and mass is inversely proportional, according to Newton's second law, and there is a direct relationship between acceleration and net external force.

<h3>What are the relation in forces and acceleration?</h3>

One of the most significant laws in all physics is Newton's second law. F = ma, where F (force) and a (acceleration) are both vector values, can be used to represent a body whose mass m is constant. A body is accelerated according to the equation if there is a net force acting on it.

Therefore, An object will remain at rest or move in a straight path at constant speed in the absence of acceleration. A force that is not balanced causes an object to accelerate.
