Answer:
Efficiency = 90 %
Wasted energy = 10 %
Explanation:
Since we have the input energy and useful output energy of the electric kettle, the only thing we are required to calculate here is its efficiency. This is gotten from
E = useful output energy/input energy × 100
E = 9/10 × 100 = 90 %
The percentage of wasted energy is
W = wasted energy/input energy × 100
W = 1/10 × 100
W = 10 %
A = (v - u) / t
a = acceleration
v = final velocity
u = initial velocity
t = time
45 = (v - 300) / 10
45 × 10 = v - 300
450 + 300 = v
v = 750 m/s
Hope this helps!

It depends on your weight, your hieght, and how fast you are falling
Answer:
newton's first law
Explanation:
this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it.

<h3><u>Answer;</u></h3>
- Make up tissues
- The simplest level of organization of life
<h3><u>Explanation;</u></h3>
- <em><u>Cells are the smallest part of an organism that can carry out all of life functions. They are the basic functional unit of all living organisms.</u></em>
- According to cell theory all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
- <em><u>A group of cells make up tissues. Tissues are a group of cells that are specialized to carry out specific functions in plants and animal bodies. </u></em>
