In my opinion, the answer would be d: a universal language. D would technically be more important because there are so many foreign scientific companies and to get the information we need to study the universe, we should communicate and give eachother what we have of our resources as we work for it.

A girl performed 50 J of work lifting a heavy box. It took her 5 seconds to lift the box. What was her power?
MAXImum [283]
The formula for power is:
P = W / T (Power = Work / Time).

We have 50 Joules of work.
We have 5 seconds of time.

Let's plug in our numbers.
P = 50 / 5

Divide 50 / 5
50 / 5 = 10.

Your power is 10 Joules per second.

I hope this helps!

How much force is required to hold an empty carton of volume 1.5 L beneath the surface in a sink of water? Assume the carton is
Gwar [14]

Answer:

It will require 14.715 N of force to hold the cartoon beneath the water.

Explanation:

Given the the volume of cartoon is 1.5 liters.

We need to find the force required to hold this cartoon beneath the water.

As we know from the Archimedes principle that the net force is equal to the volume of liquid displaced.

Given volume of the cartoon is 1.5 liters. So, 1.5 liters of water will be displaced.

And we know the density of the water is 1000\ kg/m^3. That is 1\ kg/L

And g=9.81\ m/s^2

F_N=\rho Vg\\F_N=1\times 1.5\times 9.81\\F_N=14.715\ N

So, it will require 14.715 N of force to hold 1.5 liter volume of cartoon beneath the water.
