A spider is crawling on a wall. First it crawls 1 meter up, then 1 meter to the left, and then 1 meter down. what is its total displacement

Answers

Answer 1

Answer: 1 meter up, 1 meter to the left and then 1 metter down.
It goes 1 meter up and 1 meter down, so its in the same place. The only displacement is 1 meter to the left.

Look at picture:

(hope this helps)

Answer 2

Answer: 1 meter up and then 1 meter left, and then 1 meter down. The total displacement would be 1 meter. See Ayah's pic to help you understand more better:)

Answers

The answer is the option B. a a group of stars. So the complete sentence is "A constellation is a group of stars that forms a pattern resembling animals, mythological characters, or objects. Most names of constellations originated in ancient times and took their names from the patterns that observer could watch in the sky. Some examples of constellations are Orion, Aquarium, Cancer, etc.

When a physical change occurs, the mass of the substance is conserved. This means that the total mass of the substance remains the same from beginning to end. The physical properties of the substance, such as size and shape, may change, but the amount of matter in the substance does not change.

Which of the following is a form of mechanical energy?a. internal energy
c. gravitational potential energy
b. chemical potential energy
d. electrical energy

Answers

Gravitational potential energy is a form of mechanical energy.

What is Gravitational potential energy?

Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field.

If an object is at rest and doesn't involve elastic energy, then mechanicalenergy can be equal to gravitational potential energy.

Okay so i believe that potential energy is mechanical but there are two answers with potential energy in it. Its a tough one but I think I would go with gravitational potential energy. Hope this helped!

Five race cars speed toward the finish line at the Jasper County Speedway. The table lists each car’s speed in meters/second. If each car has the same mass, which car will require the longest time to come to a full stop?Car A Car B Car C Car D Car E
890 m/s 850 m/s 790 m/s 895 m/s 870 m/s

Car A

Car B

Car C

Car D

Car E

Answers

Answer:

Car C

Explanation:

It is given that,

Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :

Car A = 890 m/s

car B = 850 m/s

Car C = 790 m/s

Car D = 895 m/s

Car E = 870 m/s

The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.

$s=(d)/(t)$

Where

d = distance

t = time required by the car to come to a full stop

$t=(d)/(s)$

So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.

Answer:

Car D

Explanation:

The mass of the car is given the same. The initial velocities are also given. eventually all the cars come to a stop. The finish line would be crossed first by the fastest car. But If all the cars decelerate at the same rate then, we can find out the time taken to come to a full stop by first equation of motion,

$v-u = at$

final velocity, v = 0

$t \propto u$ if a is same for all cars.

Car D has maximum speed ( 895 m/s). So, Car D will take the maximum time to come to a stop.
