Answer:
500 meters per squared second
Explanation:
The difference in speed between 2000 and 6000 is 4000. You divide the velocity by the time, which in this case is 8. So 4000 divided by 8 is 500 meters per second squared.
Answer:
λ = 4.2x10^-13 m
Explanation:
c = λν
c is speed of light 3x10^8 m/s
λ is wavelength
ν is frequency
3.10^8 = λ . 7.13 × 10^20
λ = 4.2x10^-13 m
Answer False
Explanation: Friction makes it stop at some point. For it to have an unlimited speed goes against beset is first law that states an object in motion with stay in motion unless acted upon by an external force, your force will be the friction of the wheels on the roller coaster
Answer:
Barium
Explanation:
The specific heat of a material is a property defined as the amount of energy required to increase the temperature of 1g of this material in 1°C = 1K
In this way, the metal that takes the least amount of energy to increase its temperature is the metal that has the lowest specific heat.
In the problem, this metal is Barium (Ba = 0.201J/gK)
B)The number of protons.
c) their atomic masses are different.
