Which of the following would have more momentum than fiona, a 313kg hippo, running at 8m/s?

kap26 [50]

Let's calculate the momentum of Fiona, given by the product between its mass and its speed:
$p=mv=(313 kg)(8 m/s)=2504 kg m/s$

Now let's compare it with the momentum of the other animals:
a) the mass of the sea turtle is missing, so we cannot calculate its momentum.
b) the momentum of the dolphin is
$p=mv=(150 kg)(18 m/s)=2700 kg m/s$
c) the momentum of the horse is
$p=mv=(380 kg)(4 m/s)=1520 kg m/s$
d) the momentum of the lion is
$p=mv=(190 kg)(11 m/s)=2090 m/s$

And we can see that the correct answer is b), because the momentum of the dolphin is greater than the momentum of Fiona.

A sealed beaker of what you are told is aqueous nickel sulfide was given to you by the local chemist and you put it on the windo

Masteriza [31]

Answer: D. It is a SUSPENSION

Explanation:

SUSPENSION

This is a combination of two or more single substances. The properties of the components involved are not however changed or lost as is the case with compounds.

For this reason this mixture can be separated due to sedimentation or filtering.

After a few days, this occurs in the aqueous nickel sulfide because the solid nickel sulfide is separating from the water.

The closer the charged particles, the... the electrostatic force.

Anna35 [415]

Answer:

please give me brain list and follow

Explanation:

Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.
