The object represented by this graph is moving

Vinil7 [7]

The object represented by this graph is moving toward the origin at constant velocity.

Option 3.

Explanation:

In the figure, x-axis is representing increase in the time and y-axis is presenting increase in the distance from bottom to up. But the line in the graph which is plotted is decreasing from high distance to small distance with increase in time. So this indicates that as the time is increasing, the distance is decreasing.

And the object is moving toward the origin as the distance of the object motion is found to decrease with increase of time as per the graph. But the slope of the graph is found to be almost constant, this indicates that the velocity of the object is constant. Thus, the object represented by this graph is moving toward the origin at constant velocity.

Materials that conduct heat and electricity well in the solid state result when

MA_775_DIABLO [31]

Materials that conduct heat and electricity well in the solid state result when metals bond with metals. This type of bonding is called metallic bonding. Metallic bonding is when positive ions (metals) are in a 'sea of negative electrons'. The electrons are delocalised, which means they can move around easily and carry charge, and this enables it to conduct electricity, even in a solid state.

The location movement and intensity of precipitation can be found by using?

vaieri [72.5K]

Answer: Doppler radar
Doppler radar or weather radar is used to locate precipitation, forecast future intensity, calculate or detecting its motion and estimates precipitation whether it is a rain, snow, hail or storm. They are also helpful in determining the structure of storms and its potential to cause severe weather.

Moreover, if a portion of the atmosphere becomes saturated with water vapor, it will condense and precipitate allowing Doppler radar to analyze and observe precipitation.

A 780 g , 54-cm-long metal rod is free to rotate about a frictionless axle at one end. While at rest, the rod is given a short b

evablogger [386]

Answer:

The angular velocity is 35.5 rad/s.

Explanation:

Step 1: Find the moment of Inertia for the rod

The moment of inertia, I, of a rod:

$I=\frac{1}{12} ML^{2}$ .......... (1)

where M = mass of rod (0.78 Kg); L = Length of rod (0.54 m).

$I=\frac{1}{12} (0.78)(0.54)^{2} =0.019\frac{Kg}{m^{2} }$

Step 2: Calculate the angular acceleration from Rotational kinetic notation

F.r = I.α ........... (2)

where F is the force acting upon the rod; r is the half length of the rod; I is the moment of Inertia and; α is the angular acceleration.

∴ (1000 N)(0.27 m) = 0.019α

α = 270 Nm / 0.019 Kgm²

α = 14210.5 rad/s

Step 3: We find the angular velocity by using the equation below:

ωf = ωi + αt ......... (3)

where

ωf is the angular velocity after the blow

ωi is the angular velocity before the blow = 0

t is the time taken for the blow to occur = 2.5 ms

ωf = 0 + (14210.5 rad/s)(2.5 ms) = 35.5 rad/s.
