Answer:

Atoms form chemical bonds to satisfy the Octet rule and become Stable element.

Explanation:

Every atom desires to achieve total eight valence electron in their outermost shell to become stable. This rule is known as octet rule.
During the chemical reaction process, every element goes through the process of receiving or donating the element to complete the octet rule to become stable.

The electronic configuration of element having eight electrons in its valence shell is the noble gases.

A truck has a velocity of 25 m/s and a momentum of 25.000 kg*m/s. What is its<br> mass?

Andrew [12]

Answer:

1000kg

Explanation:

We can use the equation "p=mv"

p is the momentum in kg m/s
m is the mass measured in kg
v is the velocity measured in m/s

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

p=25,000 kg m/s
v= 25 m/s

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg

Hi :) I don’t really understand why it’s A

Troyanec [42]

Answer:

Explanation:

1. When the block moves across a table top, F(pulling) = - F(frictional).

Sum of this forces = 0, so the block moves with uniform speed.

2. When the block is pulled on top of the table covered with beads

F(pulling) > - F(frictional).

So, the sum of forces (∑F) is a number that is more than 0 and directed to the direction of movement.

So, a = ∑F / m is positive and constant. Speed is increasing because

v(t) = v(0)+at

a is constant and directed forward.

That means a is acceleration, and constant.

At the instant the traffic light turns green, an automobile starts with a constant acceleration a of 2.70 m/s2. At the same inst

kifflom [539]

Answer:

66.85 m

Explanation:

We are given that

Acceleration ,a= $2.7m/s^2$

Speed of truck, v=9.5 m/s

We have to find the distance beyond which the traffic signal will the automobile overtake the truck.

Initial speed of automobile, u=0

We know that

$s=ut+\frac{1}{2}at^2$

Using the formula

$s=0+\frac{1}{2}(27)t^2=\frac{27}{2}t^2$

For constant speed

Acceleration, a=0

Again

$s=vt+0=9.5t$

$9.5t=\frac{27}{2}t^2$

$t=\frac{9.5\times 2}{2.7}=7.037s$

Substitute the value of t

$x=9.5(7.037)=66.85m$

Hence, the distance beyond which the traffic signal will the automobile overtake the truck=66.85 m

Which force changes the lithosphere by building up the surface?

Sunny_sXe [5.5K]

Answer:

volcanic eruptions

Explanation:

The volcanic eruptions are the ones that manage to cause changes to the lithosphere by building up new material on the surface. Through the volcanic eruptions we have release of pyroclastic material on the surface, and more importantly and in much higher amount lava flows. The lava flows quickly cool off on the surface on the Earth, and as they do they pile up new layers of igneous rocks, thus new crust on the surface of the Earth, causing changes on the lithosphere and shaping it for the foreseeable future.
