Explanation:

Volcanic Eruption

Cracks in the earth’s crust are called faults. Volcanoes and earthquakes usually occur along these faults. A volcanic eruption can lead to landslides, ash falls, mud-flows, pyroclastic flows (can burn everything in their way), and steam explosions. okay for example volcanoes people have to keep a close eye out when they live by an active search up valcanic damage and you will see what i mean

A) Fill in the blanks in the following paragraph to correctly describe the nucleus of an atom.
nydimaria [60]

Answer:

<u>Protons</u> and <u>Neutrons</u> are the two types of nucleons that make up a nucleus. The <u>electrostatic</u> force exists between <u>protons</u> in the nucleus because of their charge. Because it is repulsive, this force tends to make a nucleus <u>unstable</u>. However, the <u>strong nuclear</u> force acts between protons, between neutrons, and between protons and neutrons. This force helps to make a nucleus <u>stable</u>, because it is always attractive.

Explanation:

The nucleus of an atom contains two types of particles, protons and neutrons. Proton has a positive charge, while neutron has no charge. The protons have a repulsive electrostatic force between each other, due to like charges. Due to this repulsive force protons tend to scatter away making the nucleus unstable. In order to overcome this, a force inside the nucleus binds these protons and neutrons together. This attractive force is called strong nuclear force. This force acts on very short ranges.

Erica (39kg \;kg ) and Danny (45kg \;kg ) are bouncing on a trampoline. Just as Erica reaches the high point of her bounce, Dann
Scrat [10]

Answer:

2.57142857143 m/s

Explanation:

m_1 = Mass of Danny = 45 kg

m_2 = Mass of Erica = 39 kg

u_1 = Velocity of Danny = 4.8 m/s

v = Combined velocity

In this system the linear momentum is conserved

m_1u_1=(m_1+m_2)v\\\Rightarrow v=\dfrac{m_1u_1}{m_1+m_2}\\\Rightarrow v=\dfrac{45\times 4.8}{39+45}\\\Rightarrow v=2.57142857143\ m/s

The speed of Erica and Danny is 2.57142857143 m/s
