Answer:

Increasing temperatures evaporate water faster, causing an increase in salinity.

Explanation:

When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity.

A mass-spring system oscillates with an amplitude of 4.60 cm. If the spring constant is 234 N/m and the mass is 524 g, determine
gizmo_the_mogwai [7]

Answer:

Mechanical energy, U = 0.247 Joules

Explanation:

Given that,

Spring constant of the spring, k = 234 N/m

Mass, m = 524 g = 0.524 kg

Amplitude, A = 4.6 cm = 0.046 m

To find,

The mechanical energy of the system.

Solution,

We know that the sum of kinetic energy and the potential energy is equal to its mechanical energy. In mass-spring system, it is given by :

U=\dfrac{1}{2}kA^2

U=\dfrac{1}{2}\times 234\times (0.046)^2

U = 0.247 Joules

So, the mechanical energy of the system is 0.247 Joules.

In 2002, Colorado was suffering from extreme drought. Which technology will help Colorado reduce the effects of future droughts?
Vika [28.1K]
I would say C: Dam

Sea walls and levees stop water from overflowing onto something. Which can we good but has no impact on droughts.

Storm shelters wont impact droughts either. They are men't to protect people from storms.

A Dam on the other hand can contain and keep water in one given place. Which will save water, to be used to prevent future droughts.

Hope this helps!

In a science fiction novel two enemies, Bonzo and Ender, are fighting in outer spce. From stationary positions, they push agains
Hoochie [10]

Answer:

\frac{m_B}{m_E}=1.18

Explanation:

m_B = Mass of Bonzo

m_E = Mass of Ender

u_B = Initial Velocity of Bonzo = 2.2 m/s

u_E = Initial Velocity of Ender = -2.6 m/s

From conservation of linear momentum

m_Bu_B=m_Eu_E\\\Rightarrow \frac{m_B}{m_E}=\frac{u_E}{u_B}\\\Rightarrow \frac{m_B}{m_E}=\frac{2.6}{2.2}\\\Rightarrow \frac{m_B}{m_E}=1.18

\therefore \frac{m_B}{m_E}=1.18
