You are standing on a street corner with your friend. You then travel 14.0 m due west across the street and into your apartment
Margarita [4]

Answer:

Explanation:

We shall express each displacement vectorially , i for each unit displacement towards east , j for northward displacement and k for vertical displacement .

14 m due west = - 14 i

22.0 m upward in the elevator = 22 k

12 m north = 12 j

6.00 m east = 6 i

Total displacement = - 14 i + 22 k + 12 j + 6 i

D = - 8 i + 12 j + 22 k

magnitude = √ ( 8² + 12² + 22² )

= √ ( 64 + 144 + 484 )

= √ 692

= 26.3 m

Net displacement from starting point = 26.3 m .

What change does this cause concerning weather?
Vika [28.1K]

Answer:

More extreme weather.

Explanation:

The Conveyor Belt of tides functions on a local and global level to spread out the cold and hot temperature differences on the planet. It is a delicate but important process that is easily disrupted, which causes it to slow down. And when it slows down, all those temperature differences will become more concentrated, causing colder places to be colder and hotter places to be hotter, ultimately leading to more extreme weather events as these cold and hot spots collide more violently than before.

Here's a picture I found on it:

Question
MariettaO [177]
Electrical Energy to ThermalEnergy Conversions. 
1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electriccharges into heat (thermal energy) in the filaments that turn red hot to cook your toast.

Part 2:
the law of conservation of energy states that the total energy of an isolated system in a given frame of reference remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another.

When a driver touches a car’s steering wheel on a hot day, heat is transferred to the driver’s hands by ___________?
Alik [6]

The correct answer to this question is : C) Conduction

EXPLANATION:

Before coming into any conclusion, first we have to understand conduction.

Conduction is the mode of transmission of heat in which heat will flow from a body at high temperature to a body at low temperature in contact or from hotter part of the body to its colder part, without any actual transport of particles.

As per the question, the heat is transferred to driver's hand when he touches the steering wheel.

As there is actual contact between hand and steering wheel, the heat transmission will be conduction.
