When you brew a coffee you're creating a Solution.
Tiny particles from coffee grounds, or solutes, are dissolved in water, the solvent.
Answer:

Explanation:
A simple pendulum is a system consisting of a mass attached to a string, and oscillating in a periodic motion, back and forth, along an equilibrium position.
The period of a pendulum is the time it takes for the pendulum to complete one oscillation.
The period of a pendulum is given by the equation

where
L is the length of the pendulum
g is the acceleration due to gravity
From the formula, we see that the period of a pendulum does not depend on the mass.
Therefore, the only 2 factors affecting the period of a pendulum are:
- The length of the pendulum: the longer it is, the longer the period of oscillation
- The acceleration due to gravity: the greater it is, the shorter the period of the pendulum
You use energy from your body and press the pedals on the bike that has chains and the chains are connected to a circular ish shape and is also connected to the wheel and it spins
Answer:
F=
Explanation:
The magnitude of force required to pull the lid off the box by air pressure.
We know that Pressure, P= Force(F)/Area(A)
Force, F= P×A
Given: A=
P=
.
Therefore, F=
.
F=
Answer:

Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.

The mass of the stone is 0.2 kilograms and the acceleration is 10.0 meters per square second.
Substitute the values into the formula.

Multiply.

Convert the units.
- 1 kilogram meter per square second (kg*m/s²) is equal to 1 Newton (N)
- Our answer of 2 kg*m/s² is equal to 2 N

The force is <u>2 Newtons.</u>
