Answer:
Nope not all
Explanation:
As scientists says that not all give a solution.
Answer:
5m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s due east
Final velocity = 30m/s due east
Time = 4s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
Mathematically;
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
Acceleration =
= 5m/s²
Explanation:
What is the purpose of the scientific method?
<em><u>ans/</u></em>
the goal of any scientific method is to solve a problem or to better understand an observed event.
b.
i. What does the law of conservation of energy say?
<em><u>ans/</u></em>
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
ii. List two different kinds of energy.
<em><u>ans/</u></em>
Potential energy.
Kinetic energy.
iii. What does the law say about changes energy can undergo?
<em><u>ans/</u></em>
The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.
Crest, trough, amplitude and wavelength
Answer:
I believe it's D. FE2+ and MgCl2...
