The only way to decrease the inertia of an object is to remove some of its mass. (B)
It would be the temperature of her hand and also because it is going through the process of the water cycle it is changing from a solid to a liquid
centimeter or millimeter.
Explanation:
The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.
Length refers to how long a material is.
- There are different units of length.
- Smaller units that are microscopic are used to measure length dimensions that are very small
- For example, nanometre is used to express microscopic length values.
- Centimeters and millimeters are used for small dimensions that we can easily see.
- Longer lengths can take the order of a yard, kilometer, miles e.t.c

Force is the product of mass and acceleration .
The question is ask to find acceleration.
But acceleration is the ratio of the force and the mass.
where 600kg is the mass and 7kN is the force
NB: kilo is 1000
now we have to multiply 7N by 1000
by doing so you will have 7000N
which is the force.
Now to find the acceleration: force/ mass
which is 7000/600
therefore the maximum acceleration is 11.667
The frequency stays the same and the wavelength increases.
Explanation;
Sound waves are a type of mechanical wave which requires a material medium for transmission. The transmission of such waves occurs as a result of vibration of particles in the material medium. The faster the vibration of the particles the higher the speed of the sound waves.
When a sound enters a new medium where the sound travels faster, it means the vibration of particles is high, and the wavelength of the waves increases which means the speed of the wave has increased. The frequency on the other hand will remain constant.
