it should be better than me not then me
Answer:
B) a kinetic friction
Explanation:
The force of friction in a movement object its called kinetic friction force (<em>fk). </em>The net force acting in the direction of the movement its express, according to the Newton second law, like this: F- <em>fk. </em>That expression says that the net force produces an aceleration in the direction of the movement of the object.
Now if the force its removed, the <em>fk</em> its continue acting in the object but now in the opposite direction. And according to the Newton second law this <em>fk </em>it going to continue acting until the object stay in a still state.
<u>In conclusion</u>, if an object moves in some direction the kinetic friction force always be opposite to that direction of movement, according to the Newton second law
Things for entertainment aren't needs. For example, designer clothes, the new iPhone that just came out, fancy dining, that expensive shirt that has the same model somewhere cheaper, and sports cars are all wants, not needs.
Needs are like water, a shelter to live in, food, clothing, and running electricity. Water is essential for survival, since you could die of thirst in 2 days. A shelter will protect you from insects, weather, and uninvited guests. Living without food will kill you in 2 weeks, as you need food for energy and so let your body repair itself faster if you got injured. You need clothing to keep you warm and to cover your private parts. Running electricity is needed because electricity makes most of your needs easier to acquire.
I hope this helps! Good luck!
Of course they are needed because without them the society wouldn’t be as nice as it is right now and plus there would be no more buildings ! :)
Answer:
Gs = 2.647
e = 0.7986
Explanation:
We know that moist unit weight of soil is given as

where,
= moist unit weight of the soil
Gs = specific gravity of the soil
S = degree of saturation
e = void ratio
= unit weight of water = 9.81 kN/m3
From data given we know that:
At 50% saturation,
puttng all value to get Gs value;

Gs - 1.194*e = 1.694 .........(1)
for saturaion 75%, unit weight = 17.71 KN/m3

Gs - 1.055*e = 1.805 .........(2)
solving both equations (1) and (2), we obtained;
Gs = 2.647
e = 0.7986
