Answer:
a.
b.
Explanation:
Given:
Using the equation to find the force so replacing
a.
b.
I think since applied force and displacement are perpendicular to each other, then the work done is zero. I hope this helps.
In Oder to determine the density of an object, you must measure
the object's mass and its volume.
With those two numbers in hand, the density may then be calculated,
thusly:
<em>Density = (mass) </em>divided by<em> (volume)</em>.
Answer:
From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's continents/ surface in the present and the past. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle called convection, the rocky inner layer above the core which has a high density.
Explanation:
The first option is true, water vapor helps keep the Earth's heat from escaping into space.
