Troposphere is much warmer than the Stratosphere.
<u>Explanation:</u>
- The troposphere is the last and the lowest level of the atmosphere, so it is in close contact with the Earth's surface.
- On the other hand, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface.
- So from the above discussion, the troposphere is warmer than the stratosphere.
Answer:
Metals are lustrous, malleable, ductile, good conductors of heat and electricity.
Luster: Metals are shiny when cut, scratched, or polished.
Conductivity: Metals are excellent conductors of electricity and heat.
Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped.
Ductility allows structures to bend and deform to some extent without rupturing.
Luster: Metals have the quality of reflecting light from its surface and can be polished e.g., gold, silver and copper
Explanation:
It’s newton’s 2nd law of motion
Answer:
3.2N
Explanation:
Given parameters:
Mass of block = 1.5kg
Coefficient of kinetic friction = 0.6
Force of pull on block = 12N
Unknown:
Net force on the block = ?
Solution:
Frictional force is a force that opposes motion:
Net force = Force of pull - Frictional force
Frictional force = umg
u is coefficient of kinetic friction
m is the mass
g is the acceleration due to gravity
Frictional force = 0.6 x 1.5 x 9.8 = 8.8N
Net force = 12N - 8.8N = 3.2N
