Answer:
Gravitational energy
Explanation:
when over head , when it hits the floor thermal energy
Answer:
- magnitude : 1635.43 m
- Angle: 130°28'20'' north of east
Explanation:
First, we will find the Cartesian Representation of the and vectors. We can do this, using the formula
where its the magnitude of the vector and θ the angle. For we have:
where the unit vector points east, and points north. Now, the will be:
Now, taking the sum:
This is
Now, for the magnitude, we just have to take its length:
For its angle, as the vector lays in the second quadrant, we can use:
<h2>
a) Volume of anchor is 0.019 m³</h2><h2>
b) Weight of anchor in air is 1463.17 N</h2>
Explanation:
a) Weight loss in water = Volume of object x density of water x acceleration due to gravity
183 = Volume of anchor x 1000 x 9.81
Volume of anchor = 0.019 m³
b) Weight = Mass x acceleration due to gravity = Volume x Density x acceleration due to gravity
Weight of anchor in air = Volume of anchor x Density of anchor x acceleration due to gravity
Weight of anchor in air = 0.019 x 7850 x 9.81 = 1463.17 N
Weight of anchor in air = 1463.17 N
