At sea level, you're 6400 km away from the earth's center. Where gravity is 0.4 fewer,
in other words 0.6 its sea level value, you're x km from the center, where:
(6400 / x) ^ 2 = 0.6)
Take note that gravity is an opposite square force.
So 6400 / x = 0.7746
so x = 8262 km from the Earth's center
so you're 8262 – 6400 = 1862 km above the Earth's surface
<u>Answer:</u> The momentum of the car is 16000 kg.m/s
<u>Explanation:</u>
Momentum is defined as the force that keeps the object moving. It is also defined as the product of mass and velocity of an object.
Mathematically,
where,
p = momentum of the car = ?
m = mass of the car = 800 kg
v = velocity of the car = 20 m/s
Putting values in above equation, we get:
Hence, the momentum of the car is 16000 kg.m/s
Adding oil to the moving parts of machines can do that because it makes it smoother and takes the rust off of it.
Answer:
Total distance = 6.5 km
Explanation:
Let the distance be denoted by the vectors drawn from A, B, C, D, E, and F.
Then the distance covered can be calculated by adding the vectors in the direction given.
Total distance = 3km + 1km+ 1.5km+ 0.5km+ 0.5km
Total distance = 6.5 km
If we were to find the displacement ( shortest distance) then the head to tail rule would be applied using the vectors.
