The change in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy of a body due to its motion.
To calculate the increase in the kinetic energy of the monster truck, we use the formula below.
Formula:
- ΔK.E = m(v²-u²)/2............. Equation 1
Where:
- ΔK.E = Increase in kinetic energy of the monster truck
- m = mass of the monster truck
- v = final velocity of the monster truck
- u = initial velocity of the monster truck.
From the question,
Given:
- m = 5000 kg
- v = 18 m/s
- u = 11 m/s.
Substitute these values into equation 1
- ΔK.E = 5000(18²-11²)/2
- ΔK.E = 2500(324-121)
- ΔK.E = 2500(203
- ΔK.E = 507500 J
Hence, The increase in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500.

Force is defined as the push or pull applied to the body. Its unit is Newton. The net force will be 10 N on the right side.
What is force?
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
F₁ is forced by person 1 = 100 N
F₂ is forced by person 2= 90 N
Fₓ is the net force
Fₓ = F₁ -F₂
Fₓ = 100-90
Fₓ= 10 N
Hence the net force will be 10 N on the right side.

Explanation:
Solution:
Let the time be
t1=35min = 0.58min
t2=10min=0.166min
t3=45min= 0.75min
t4=35min= 0.58min
let the velocities be
v1=100km/h
v2=55km/h
v3=35km/h
a. Determine the average speed for the trip. km/h
first we have to solve for the distance
S=s1+s2+s3
S= v1t1+v2t2+v3t3
S= 100*0.58+55*0.166+35*0.75
S=58+9.13+26.25
S=93.38km
V=S/t1+t2+t3+t4
V=93.38/0.58+0.166+0.75+0.58
V=93.38/2.076
V=44.98km/h
b. the distance is 93.38km
They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.
Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.
Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.
