Answer:
245.25 Newtons
Explanation:
the gravitational force of the earth is 9.81 N/Kg
And so to work this out you would multiply 25 by 9.81 to give you 245.25
Answer:
Exercise combined with a diet can help manage weight, or you can contact a doctor
Explanation:
Answer:
Mirages happen when the ground is very hot and the air is cool. The hot ground will have a warm layer of air just above it. when the light moves through the cold air and into the layer of hot air it is refracts (bent).
The earths system includes the atmosphere, which contains all of the planet's air. These spheres are closely connected. For example, many bird (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere).

Answer:
Explanation:
Given
mass of sled =26 kg
coefficient of static friction
coefficient of kinetic friction
In order to move sled from rest we need to provide a force greater than static friction which is given by
After Moving Sled kinetic friction comes in to play which is less than static friction
therefore minimum force to keep moving sledge at constant velocity is 18.34 N
