Answer:
friction is when two objects tough with force basically. when an object is rubbed against something. when an object comes in contact with something else. or ig u can call it hot air rubbing off the inevitable force lol that works too , bud
whatever helps u rememeber
Answer:
In an earthquake prone area, the things that are needed to be considered for the buildings to stand constant and no cause of damages are as follows-
- The foundation of the building must be made strong, using large amount of concretes so that it can hold the entire load of the building.
- The pillars of the buildings are also should be firmed, rigid, strong and thick.
- The buildings are needed to be construct in such a way that during any seismic event, the forces can be redistributed easily through the body of the building without causing any damage.
- The buildings must be overall comprised of holding high strength and stiffness.
Answer:
(a) θ = 55.85 degree
(b) 7.89 km
Explanation:
Using vector notations
A = 1.88 km south = 1.88 (- j) km = - 1.88 j km
B = 9.05 km 47 degree north of east
B = 9.05 ( Cos 47 i + Sin 47 j) km
B = (6.17 i + 6.62 j) km
Net displacement is
D = A + B
D = - 1.88 i + 6.17 i + 6.62 j = 4.29 i + 6.62 j
(a) Angle made with positive X axis
tanθ = 6.62 / 4.29 = 1.474
θ = 55.85 degree
(b) distance = 
distance = 7.89 km
Explanation:
No. Surface contact area also no. The main issue is the types of materials in contact. Surface roughness somewhat matters. Certain surfaces such as ice are special in that pressure melts the ice.
Pot conducts heat
Bin Insulates from heat
Plate Insulate from heat and brittle
Explanation:
Any material that is able to conduct heat is known as a conductor. Also, most heat conductors also allows electric current to pass through.
Most metals are categorized as heat conductors. A pot is usually made of conductors which helps to transfer heat to cook food.
Any material that does not conduct heat is called an insulator. Likewise, they do not allow electric current to pass through.
Most non-metals, plastics, rubber, wood, paper are insulators.
A brittle material that breaks into many pieces is a plastic. Their elastic limit is obviously exceeded and they lack internal cohesion and order. A glass used in making plate is also plastic and brittle.
