Answer:

Explanation:

chemical because first of all its simply not possible to create mass. second of all a physical; change is not done by creating a new substance, you can shred paper thats physical, you burn paper, thats chemical. and finally a change of state is the three stages of matter, solid liquid and gas. none of these are changes that will always happen when there is a new substance is made.

A 65.0 kg ice skater standing on frictionless ice throws a 0.15 kg snowball horizontally at a speed of 32.0 m/s. What is the vel

spin [16.1K]

Answer:

(d) 0.07 m/s

Explanation:

Given Data

Snowball mass m₁=0.15 kg

Ice skater mass m₂=65.0 kg

Snowball velocity v₁=32.0 m/s

To find

Velocity of Skater v₂=?

Solution

From law of conservation of momentum

$m_{1}v_{1}=m_{2}v_{2}\\ v_{2}=\frac{m_{1}v_{1}}{m_{2}}\\ v_{2}=\frac{(0.15kg)(32.0m/s)}{65.0kg}\\ v_{2}=0.0738m/s\\or\\v_{2}=0.07 m/s$

So Option d is correct one

Why is salt water a better conductor of electricity than river water?

Tamiku [17]

Answer: The conductivity of water depends on the concentration of dissolved ions in solution. ... This is because the Sodium Chloride salt dissociates into ions. Hence sea water is about a million times more conductive than fresh water.

Help ASAP please (: The waves with the MOST energy have

tino4ka555 [31]

Answer: C

high; large

Explanation:

The wave energy is related to its amplitude and frequency.

The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.

Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.

Therefore, The waves with the MOST energy have high amplitudes and large

frequencies.
