A convenient way to show how a fixed quantity is broken down into parts is by using a circle graph.
A circle graph shows different fixed parts in relation to the whole. All of the parts make up the whole.
Answer:
The volume of the block is equal to the volume of water displaced by the block.
Explanation:
Volume refers to the amount of space occupied by a given object (in this case the block). When an object such as the block is immersed in water, it displaces its own volume of water. This volume of water displaced is equal to the volume of the block. Hence we can write;
Final Volume of water - Initial Volume of water= Water Displaced = Volume of the block
Recall that the density of a body is given by;
Density= mass/volume
If we obtain the volume of the block by measuring the volume of water displaced by the block, then we weigh the block using a weighing balance, we can obtain the density of the block easily from the relationship shown above.
I think it’s the third law “for every action, there’s an equal and opposite reaction”
Answer:
First, we need to convert Wh to joules. This can be easily done. Wh means that you are doing 1W of work per hour. We need to find out how much work this is.
We lost 60% of this energy on friction and other losses which means that this leaves us with:
We are going to use this energy to do work against the force of gravity. This means that when we reach our maximum height all of our energy will be used and thus converted the potential energy in the gravitational field.
