10cm=14cm which well give you something idont know lol
Answer:
Gradient of the hill is 53.33m/km which is lesser than the 500 m/km. So, he will be able to climb the hill conveniently.
Explanation: Given that
Maximum gradient = 500 m/km
Total distance = 1.5 km
Starting elevation = 20 m
Final elevation = 100 m
Gradient = change in elevation/ total distance.
Now, substitute the values into the formula.
Gradient = (100m - 20m)/1.5km
= 80m/1.5km
= 53.33m/km
Gradient of the hill is 53.33m/km which is lesser than the 500 m/km. So, he will be able to climb the hill conveniently.
Explanation:
Geocentric model said that the Earth is at the center of the universe and everything revolves around it. It was considered to be stationary. Galileo proved this model incorrect with the help of his astronomical observations. Some of the key observation that he used to support the heliocentric model were:
1. He proposed the theory that the tides on the Earth occur because of its motion.
2. He observed the phases of the Venus which meant that the Venus revolved around the Sun and not the Earth.
3. He observed other planets and thus noted that they also move around the Sun and not Earth.
4. He discovered the Moons of other planets.
Answer:
Kinetic energy, E = 40 Joules
Explanation:
Given that,
Mass of the object, m = 2 kg
It is released from rest from a height of 3 m above Earth's surface,
We need to find the kinetic energy the object have when it reaches a height of 1 m,
It is a case of conservation of mechanical energy. It states that the total energy of the system remains constant. The kinetic energy is given by :
E = 40 Joules
So, the kinetic energy of the object when it reaches a height of 1 m is 40 joules. Hence, this is the required solution.
