Answer:
Weight = 3.924 N
Bouyant force = 2.5N
Apperent weight= 1.424N
Explanation:
Radius of the sphere = 0.0165 m
Volume of sphere = (4πr³)/3
Volume = 4.189*(4.49*10^-6)
Volume = 1.88*10^-5
For the weight.
Mass = density* volume
Mass = 2.14*10^4 *(1.88*10^5)
Mass = 0.4 kg.
Weight = mass * acceleration due to gravity
Weight = 0.4*9.81
Weight = 3.924 N
For the buoyant force Fb
Fb = volume * density of fluid* acceleration
Fb = (1.88*10^5)*1.36 × 10^ 4*9.81
Fb = 2.5N
For Apperent weight
True weight - buoyant force = Apperent weight.
3.924- 2.5N= 1.424N
In the given problem, explain why the types of technology valued varies
from location to location.
There are a lot of factors that could determine the evolvement of
technology from a certain place or location:
1. Resources. One is resources and its
availability is one crucial factor.
2. Accessibility. Other areas are
fairly secluded from industrialization and urbanization.
3. People and culture. Humans are the
resources that determines the flow of technology if they want it or not in
their area.
Answer:
<h3>The answer is 150 J</h3>
Explanation:
The work done by an object can be found by using the formula
<h3>workdone = force × distance</h3>
From the question we have
workdone = 15 × 10
We have the final answer as
<h3>150 J</h3>
Hope this helps you
B) The transfer of energy from the hydrosphere to the atmosphere
This is because oceans are part of the hydrosphere. As the air warms it flows up into the atmosphere.
Hope this helps!
Answer:
8381
Explanation:
Workdone=Force x distance
W= 289x 29
W=8381J
