What is the magnitude of the displacement?

aleksklad [387]

A) 20 m

<h3>What is called magnitude of displacement?</h3>

The magnitude of displacement is defined as the shortest distance between the initial and final position of the object.

For a particle in motion, the magnitude is either less than or equal to the distance travelled.

Also,

Velocity is simply defined as the rate of change of displacement with time.

Mathematically, it can be expressed as:

Velocity = displacement / time

According to the question,

The following data were obtained:

Time = 5 s

Velocity = 4 m/s

Displacement =?

Velocity = displacement / time

4 = d / 5

D = 4 × 5

D= 20 m

Hence,

20 m is the magnitude of the displacement of the object after it travelled for five seconds.

When spray is applied to a car, the paint has a negative charge and the surface of the car has a positive charge. Some processes

RUDIKE [14]

Answer:

Based on the properties electrically charged particles, we have that unlike charges attract and like charges repel each other. In order for proper application of an electrostatically negatively charged paint to be properly applied on the metal body surface of a vehicle, require that for attraction, the surface of the vehicle should be grounded and positively charged so as to effectively attract the negatively charged paint particles as it exits the nozzle, to form a strong attachment with the positively charged surface of the vehicle

Consider a household that uses 22.0 kW-hour of electricity per day on average. Most of that electricity is supplied by fossil fu

Lelu [443]

Answer:

$A_{net} = 13.469\,m^{2}$

Explanation:

The daily energy consumption of the household is:

$\Delta E_{day} = (22\,kWh)\cdot (\frac{3600000\,J}{1\,kWh} )$

$\Delta E_{day} = 79200000\,J$

The needed area of solar panel to power the household is:

$\Delta E_{day} = \eta\cdot G\cdot A_{net}\cdot \Delta t$

$A_{net} = \frac{\Delta E_{day}}{\eta\cdot G\cdot \Delta t}$

$A_{net} = \frac{79200000\,J}{(0.181)\cdot (376\,\frac{W}{m^{2}} )\cdot (86400\,s)}$

$A_{net} = 13.469\,m^{2}$

What is the number at the end of an isotope’s name?

Lera25 [3.4K]

Explanation:

The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope's name is the -mass number. While looking at xenon (Xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group.

20 cm long 10 cm wide and 5 cm thick as a mass of 500 g determine the greatest pressure that can be exerted by block on the flat

uysha [10]

100000 Pascal

Explanation:

pressure= force/area

Max pressure= force/min area

so f=5

min area= 5×10^-5

5÷5*10^-5 = 100000pascal
