What is the difference between distance and displacement? Give an example of a situation where distance and displacement both have the same magnitude. Give another example, where distance and displacement have different values. Make sure to address the terms "vector" and "scalar" in your response.

Answers

Answer 1
Answer:

Explanation :

Distance is total path travelled by an object during its entire journey. It is a scalar quantity i.e only magnitude.

Displacement is the shortest distance covered by an object. It is basically the change in position of object. It is a vector quantity i.e direction as well as magnitude.

When an object is travelling in a straight line and stops at the end point, then both distance and displacement are same.

When an object is travelling in a straight line and then changes its direction or we can say come backwards then the magnitude of distance and displacement are different.

Why is saturn still giving off extra energy?Please help!!!!!!!!

Homework due tomorrow!

Last question!!!!!

Answers

There is not a "for sure" answer yet, but scientist thinks that it might be due to Saturn's cloud cover, if the cloud cover fluctuated, then Saturn would scatter infrared light differently, giving off more energy than it needs to. 

a truck is moving around a circular curve @ a uniform velocity of 13m/s. if the centifrical force on truck is 3,300N with truck mass of 1600kg. What is curve radius?

Answers

Answer

81.94 m


Explanation

The centripetal force of an object moving in a circular path is given by:

F = mv²/r  Where m is the mass of the object, v is the constant velocity and r is the radius of the curve.

F = mv²/r

3,300 = (1600×13²)/r

3,300 = 270,400/r

r = 270,400/3,300

  = 81.94 m

An 100W light bulb is on 6 hours work out the energy (kWh) used and the cost of it (1kWh = £0.1359) with working out please

Answers

1,000 W  =  1 kW
100 W  =  0.1 kW

           (0.1 kW) x (6 h) = 0.6 kWh    <=== energy

           (0.6 kWh) x (£0.1359/kWh)  =  £0.0815     <=== cost of it
