Answer:A
Explanation: number that shows the total atomic mass of the substance
Answer:
a)
b)
c)
d) Δs=4428ft
Explanation:
From the exercise we know the equation of position
a) To calculate the velocity we need to derivate the equation of position
So, v(0) is:
b) To find the two times where the particle stops A and B we need to solve the quadratic equation:
Solving for t
and
c)
d) Δs=4428ft-0ft=4428ft
Answer:
Explanation:
We know that,
Neptune is 4.5×10^9 km from the sun
And given that,
Earth is 1.5×10^8km from sun
Then,
Let P be the orbital period and
Let a be the semi-major axis
Using Keplers third law
Then, the relation between the orbital period and the semi major axis is
P² ∝ a³
Then,
P² = ka³
P²/a³ = k
So,
P(earth)²/a(earth)³ = P(neptune)² / a(neptune)³
Period of earth P(earth) =1year
Semi major axis of earth is
a(earth) = 1.5×10^8km
The semi major axis of Neptune is
a (Neptune) = 4.5×10^9km
So,
P(E)²/a(E)³ = P(N)² / a(N)³
1² / (1.5×10^8)³ = P(N)² / (4.5×10^9)³
Cross multiply
P(N)² = (4.5×10^9)³ / (1.5×10^8)³
P(N)² = 27000
P(N) =√27000
P(N) = 164.32years
The period of Neptune is 164.32years
Therefore, it is safe to say that as the mass of an object<span> increases so does </span>its <span>inertia. ... Mass and </span>velocity<span> are both directly proportional to the </span>momentum<span>. </span>If<span> you increase either mass or </span>velocity<span>, the </span>momentum<span> of the </span>object<span> increases proportionally. </span>If<span> you </span>double<span> the mass or </span>velocity<span> you </span>double<span> the </span>momentum<span>.</span>
