We all know that a soccer ball is composed of matter, and matter is made up of particles of atoms such as protons and electrons, and matter of soccer ball can also be made up of waves of electrons and protons. This is now in a realm of quantum mechanics were everything defies our logic and common sense. Atoms can be defined as particle and also as a wave, they called it particle wave duality, it means atoms behave as wave and a particle. This is the trickiest part, Imagine that you are not observing the flight of the soccer ball, it actually behave as a wave as it moves in its trajectory, but at the moment that you are going to observe the flight of the soccer ball, it will behave as a particle as you see on its trajectory, becoming a ball or a particle, and that is the weird of part of quantum mechanics, the world of subatomic particles defies all common sense or logic. Remember that we will never see the wave like motion of any particle, because nature always plays a trick on our mind or senses.
ANSWER 1: The manipulated variable is the fertilizer since the other factors (water and sunlight) are given in equal
amounts.
It is a controlled experiment because one group receives fertilizer while the other does not. Any
differences in growth should be due to either having fertilizer or not.
ANSWER 2: In order for it to be a theory, it has to be tested numerous times by multiple scientists.
Hope it helps. God bless
Answer:
291.1 Nm
Explanation:
Torque is simply the force required to cause a rotation, it is also sometimes referred to twisting force. In simple terms Torque is the rotational equivalent to the linear moment.
Calculating torque is a very simple process and is done with the following formula
T = F x d x SinФ
where
T = Toque (Nm)
F = Applied Force (N)
d = Distance from the axis of rotation (m)
Ф = Angle between F and d (Degree)
hence the torque is
T = 41 x 7.1 x Sin90
T = 291.1 Nm
Answer:
The answer is D.
Explanation:
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
The kinetic energy increase because as temperature warms up particles move faster
