A car that increase its speed from 20 km/h to 100 km/h undergoes -------acceleration,

Difference between regular and irregular object.

DaniilM [7]

<h2>Answer:</h2><h2>Regular object</h2>

Those substance which have fixed geometrical shape are called regular object.
For example: books,pencils, basketball etc.

<h2>Irregular object</h2>

Those substance which do not have geometrical shape are called irregular object.
For example: a piece of stone,a broken piece of brick,leaf etc.

Hope this helps....

Good luck on your assignment.....

A bicycle tire is spinning counterclockwise at 3.00 rad/s. During a time period Δt = 2.30 s, the tire is stopped and spun in the

emmasim [6.3K]

Answer:

Δω = -6.00 rad/s

α = -2.61 m/s²

Explanation:

Step 1: Data given

A bicycle tire is spinning counterclockwise at 3.00 rad/s

Δt = 2.30 s

In theopposite (clockwise) direction, also at 3.00 rad/s

Step 2: Calculate the change in the tire's angular velocity Δω

Δω = ωf - ωi

ωf = - 3.00 rad/s

ωi = 3.00 rad/s

Δω = ωf - ωi = -3.00 - 3.00 = -6.00 rad/s

Step 3: Calculate the tire's average angular acceleration α

α = Δω / ΔT

α = -6.00 rad/s /2.30s

α = -2.61 m/s²

A negative angular acceleration means a decreasing angular velocity

A 200g of iron at 120 degrees and a 150 g piece of copper at -50 degrees are dropped into an insulated beaker containing 300 g o

kodGreya [7K]

Answer:

T = 15.03°C

Explanation:

given data:

copper specific heat = Sc = 0.385 J/g °C

iron specific iron = Si = 0.450 J/g °C

specific heat of ethanol = Se = 2.46 J/g °C

net heat loss is equal to zero

$(m*S*\Delta T)_{copper} +(m*S*\Delta T)_ {iron} +(m*S*\Delta T)_ {ethanol} = 0$

$150*0.385 *( T - (-50)) + 200*0.450*(T - 120) + 300*2.46 * (T -20) = 0$

$57.75( T - (-50)) + 0.90(T - 120) +738(T -20) = 0$

$57.75T + 2887.5 + 0.90T - 108 + 738T - 14760 = 0$

$57.75T + 0.90T+738T = - 2887.5 + 108+14760$

$796.65T= 11980.5$

T = 15.03°C

ruslelena [56]

Answer:

Emotions. The amygdala is part of the limbic system of the brain, which is involved with emotions and other reactions to stimuli. The amygdala is a processing center that is hooked up to receive incoming messages from our senses and our internal organs. It is highly involved with different emotional responses
