A car moved 60 km East and 90 km West. What is the displacement?

Physics
1 answer:
Reptile [31]3 years ago
7 0

Answer:

We have been given that car is moving 60 km in east

And 90 km in west

That means we are given two different directions  

So, if distance in East is taken to be positive 60 km

Then the distance when car is moving in west direction will be taken as -90 km

So, the displacement means how far the object is from to initial to final position.

So, the displacement will be  (-90)+60 = -30

So, it will be in -30 km (minus is west direction).

How do scientists know the continents were once closer than they are today? Explain your answer in 2-3 complete sentences.
WITCHER [35]

Answer:

Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. 

 

The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.

1.      A rocket is forced forward by the ______ force of its engines, expelling gases out the rear of the rocket.​
AURORKA [14]

There are two forces acting on a rocket at the moment of lift off: Thrust pushes the rocket upwards by pushing gases downwards in the opposite direction.Weight is the force due to gravity pulling the rocket downwards towards the centre of the earth.So I'm thinking the answer is THRUST.

A neutral copper block is polarized as shown in the figure below, due to an electric field made by external charges (notshown).
Fudgin [204]

Answer:

As point B is located inside the copper block so net electric field at point B is j.

Explanation:

Consider the figure attached below. The net electric field at location B,that is inside the copper block is zero because when a conductor is charged or placed in an electric field of  external charges, net charge lies on the surface of conductor and there is no electric field inside the conductor. As point B is located inside the copper block so net electric field at point B is zero as well direction of net electric field at point B is zero.
