To solve this problem we will apply the theoretical concepts and definitions given for the specific weight, density and specific gravity. Consider also that a barrel contains 159 liters or
Consider the net weight of the oil which would be
The specific weight is defined as the proportion of weight by volume thereof, therefore
Through the information given we could find mass and density through the following relations:
Mass
Density
Specific gravity,
Answer:
axb
Explanation:
because the singular order
Answer:
3.94784176044N/m
Explanation:
The period of a spring is found using the formula T=2π, where m is the mass and k is the spring constant.
The period can also be found using the formula T=, where f is the frequency.
T=T
∴2π=
2π=1/0.1
=10/2π
10/k=1.59154943092²
10/2.53302959106=k
k=3.94784176044N/m

Answer:
<em>The green car had the greatest momentum</em>
Explanation:
<u>Momentum</u>
Momentum can be defined as "mass in motion" and is calculated as the product of the mass of the object by its velocity.
Being v the magnitude of the velocity and m the mass of the object, the momentum is calculated with:
p = mv
The green car had a mass of m1=1200 kg and crossed the finish line at v1=53 m/s. Hence, its momentum was:
p1 = 1200 Kg * 53 m/s = 63600 Kg.m/s
The red car had a mass of m2=1100 kg and crossed the finish line at v2=55 m/s. Hence, its momentum was:
p2 = 1100 Kg * 55 m/s = 60500 Kg.m/s
Since p1 > p2, then the green car had the greatest momentum
