Explanation:
The atmosphere is heated in several ways - heat from the core of the Earth, by radiation from the Sun, conduction from contact with warm land and water, convection to even out the temperature and by absorption of infrared radiation from the warm land and water. The core of the Earth is very hot.
Answer:
The compress of the spring is 0.495.
Explanation:
Given that,
Mass = 50 kg
Spring constant = 8000 N/m
height = 2.0 m
We need to calculate the compress of the spring
Using law of conservation of energy

Where, m = mass
g = acceleration due to gravity
h = height
k = spring constant
x = distance
Put the value into the formula



Hence, The compress of the spring is 0.495.
Answer:
<h3>10.0m</h3>
Explanation:
The displacement of the dog is the distance moved in a specified direction. It will be gotten using pythagoras theorem as shown;
d² = 8²+6²
d² =64+36
d² = 100
square root both sides
√d² = √100
d = 10m
Hence the displacement of the dog to the nearest tenth is 10.0m
