Answer:
Three ways that waves may interact with matter are reflection, refraction, and diffraction. Reflection occurs when waves bounce back from a surface that they cannot pass through. Refraction occurs when waves bend as they enter a new medium at an angle and start traveling at a different speed.

8.908 G/cm^3 is the density of a nickel
Hello!
The statements that are characteristics of matter in the gaseous state are
A, B, C, and EAll these statements describe gases. Statement D is the only one that doesn't describe a gas. The pressure of a gas
depends on the temperature. This is described in the
Ideal Gas Law (
), and also in the
Gay-Lussac's Law (
). These Laws describes how the pressure of a gas changes with temperature.
Have a nice day!
Answer:
F = 50 N
Explanation:
Given data:
Mass of car = 250 Kg
Acceleration of car = 0.20 m/s²
Force required = ?
Solution:
Formula:
F = m×a
F = applied force
m = mass
a = acceleration
Now we will put the values in formula.
F = 250 Kg × 0.20 m/s²
F = 50 Kg.m/s²
Kg.m/s² = N
F = 50 N
