if im wrong im very sorry
Answer:
2838
Explanation:
We know that,
kilometre = 1000 metre
1000 can be written as 10³ which is kilo.
Given,
88.0km = 88.0×1000
= 88.0×10³m
When Tyler drives 50 km north and then drives back 30 km south, we have:
1. The distance that he covers is 80 km.
2. Tylor's displacement is 20 km.
1. The distance is a scalar that is given by the sum of the kilometers traveled by Tyler as follows:
Hence, the distance traveled by Tyler was 80 km.
2. The displacement is a vector that depends on the direction of travel. Takin the north direction as positive we have:
Therefore, Tyler's displacement is 20 km.

I hope it helps you!
Answer:
80 km is distance and 30km north is displacement
Explanation:
distance= 50+30=80km
displacement= 50-20=30
his displacement is 30km north
What is the focal length of this lens in air?
Answer:
The focal length is 12 cm and the lens is converging.
Explanation:
Given that,
Radius, R ₁=10 cm
R₂ =15 cm
Index of refraction n= 1.5
We need to calculate the focal length of the lens
Using formula of focal length
Put the value into the formula
The focal length of the lens is positive so the lens is converging.
Hence, The focal length is 12 cm and the lens is converging.
A biconvex lens is a type of converging lens. Using the Lensmaker's formula and the given values, the focal length of the lens in air is calculated to be 30cm.
A biconvex lens, which is defined by both surfaces of the lens bulging outwards, is a form of converging lens due to its ability to bend parallel light rays toward a single focal point after they pass through the lens. The focal length of the lens can be calculated using the Lensmaker's formula, which is 1/f = (n-1)[(1/R1) - (1/R2)]. Applying the given values, we find that the focal length f = 1/[(1.5-1)[(1/10)-(1/15)]] = 30cm.
Therefore, this biconvex lens is a converging lens with a focal length of 30cm in air.

Answer:
Mass, m = 16.02kg
Explanation:
Given the following data;
Force, F = 157N
Since it's a free fall, acceleration, a = g = 9.8m/s² (acceleration due to gravity).
To find the mass;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
Making mass (m) the subject of formula, we have;
Substituting into the equation;
Mass, m = 16.02kg
Therefore, the mass of the rock is 16.02kg.
