Yes since the heavy truck it’s way bigger it can cause more damage to the passenger car
Answer:
3.75 billion years
Explanation:
From the question given above, the following data were obtained:
Half-life (t½) = 1.25 billion years
Number of half-lives (n) = 3
Time (t) =?
The time taken for the sample of potassium-40 to contains one-eighth the original amount of parent isotope can be obtained as:
n = t / t½
3 = t / 1.25
Cross multiply
t = 3 × 1.25
t = 3.75 billion years.
Therefore, it will take 3.75 billion years for the sample of potassium-40 to contains one-eighth the original amount of parent isotope
Given that,
At 3.00 m from a source that is emitting sound uniformly in all directions, the sound level is 60.0 dB.
To find,
The distance from the source would the sound level be one-fourth the sound level at 3.00 m.
Solution,
The intensity from a source is inversely proportional to the distance.
Let I₁ = 60 dB, r₁ = 3 m, I₂ = 60/4 = 15 dB, r₂ =?
Using relation :

So, at a distance of 6 m the sound level will be one fourth of the sound level at 3 m.
The acceleration of gravity on Mars is about 3.7 m/s². (b)
So anything located on the surface of Mars weighs about 38% of what it would weigh if it were on Earth.

Explanation:
Scientific use: The Einstein's THEORY of relativity states that "Time Is Absolute".
Everyday use: Einstein's LAW of relativity says that time is not the same at all places and events.
