Explanation:
Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. ... Because continental crust is less dense than oceanic crust it floats higher on the mantle, just like a piece of Styrofoam floats higher on water than a piece of wood does.
The continental crust is by far the older of the two types of crust.
Hope this helps you out ; )
whether or whether the conclusions apply to people whose location and circumstances differ from those of the study's participants need to asked to ensure both the external and internal validity of your results
<h3>How can external validity be guaranteed?</h3>
Broad inclusion criteria that produce a study group that more closely mimics real-life patients and, in the case of clinical trials, selecting interventions that are practical to implement can both boost external validity.
<h3>What steps would you take to make sure your study is reliable and valid?</h3>
The development of a solid study design, the selection of suitable methodologies and samples, and the meticulous and consistent execution of the research are all necessary for the reliability and validity of your findings.

Answer:
2000 kg/m³
Explanation:
Density = (mass[kg])/(volume[m³])
Density of the brick = (.128kg)/(.02•.04•.08) = 2000 kg/m³
Answer:
a) Team A will win.
b) The losing team will accelerate towards the middle line with 0.01 m/
Explanation:
Given that Team-A pulls with a force , 
and Team-B pulls with a force , 
∵ 
The rope will move in the direction of force 
.
∴ Team-A will win.
b) Considering both the teams as one system of total mass , 
Net force on the system , 
= 50-45 = 5N
Applying Newtons first law to the system ,
F = ma , where 'a' is the acceleration of the system.
Since , both the teams are connected by the same rope , their acceleration would be the same.
∴ 5 = 499×a
∴ a = 0.01 m/
