Several different incandescent radiation sources are listed in the table below, along with their respective temperatures. Sunlig

ht is provided as a baseline measurement at the top of the table. You will determine the peak intensity for each source with respect to its visible color spectrum. You also estimate the amount of emitted energy that falls in the visible light spectrum. To do so drag the slider to reach the temperature listed in the first column of the table. You can also type in the temperature value in the text box above the temperature slider. use the buttons to zoom in or out on either the vertical or horizontal axis to easily observe the curve (and the peak). The peak should be as high as possible, while still being visible on screen. You should extend the scale far enough to the right to see the curve reach very close to zero emission on the right. estimate the percentage of emitted energy that appears to fall within the visible spectrum and enter that value in the table. You can do this by estimating the area under the energy curve in the visible region as compared to the total area under the curve.

A 1.20 kg solid ball of radius 40 cm rolls down a 5.20 m long incline of 25 degrees. Ignoring any loss due to friction, how fast
sladkih [1.3K]

Answer:

1.6s

Explanation:

Given that A 1.20 kg solid ball of radius 40 cm rolls down a 5.20 m long incline of 25 degrees. Ignoring any loss due to friction,

To know how fast the ball will roll when it reaches the bottom of the incline, we need to calculate the acceleration at which it is rolling.

Since the frictional force is negligible, at the top of the incline plane, the potential energy = mgh

Where h = 5.2sin25

h = 2.2 m

P.E = 1.2 × 9.8 × 2.2

P.E = 25.84 j

At the bottom, K.E = P.E

1/2mv^2 = 25.84

Substitutes mass into the formula

1.2 × V^2 = 51.69

V^2 = 51.69/1.2

V^2 = 43.07

V = 6.56 m/s

Using the third equation of motion

V^2 = U^2 + 2as

Since the object started from rest,

U = 0

6.56^2 = 2 × a × 5.2

43.07 = 10.4a

a = 43.07/10.4

a = 4.14 m/s^2

Using the first equation of motion,

V = U + at

Where U = 0

6.56 = 4.14t

t = 6.56/4.14

t = 1.58s

Therefore, the time the ball rolls when it reaches the bottom of the incline is approximately 1.6s

1. If a model train car with a momentum of 12 kg•m/s collides with a 2 kg model train car that is not moving, what is the total
wariber [46]

Answer:

P_{f} = 12 \ kg.m/s

Explanation:

Given data:

Momentum of moving model train, P_{1} = 12 \ kg.m/s

Mass of the stationary model train, m = 2 \ kg

Initial speed of the stationary model train, v = 0

Assume there is no external force is acting on the given train system.

In this case, the total linear momentum of the trains would be conserved.

Let the final linear momentum of the trains be P_{f}.

Thus,

P_{i} = P_{f}

P_{1} + P_{2} = P_{f}

P_{1} + mv = P_{f}

12 + 2 \times 0 = P_{f}

\Rightarrow \ P_{f} = 12 \ kg.m/s.

Looking at this barometer, is the air pressure high or low? What type of weather can be predicted?
ASHA 777 [7]
It really depends on the altitude of the barometer.

-- If the picture was taken in Denver, Colorado, where the long-term
average atmospheric pressure is around 24.5", then this barometer
is showing slightly higher than normal, and good weather can be
predicted.

-- If the picture was taken anywhere along the east coast of the US,
where standard "sea level" pressure is 29.92", then this barometer
is reading alarmingly low !  There's either a hurricane in progress
right now, or one can be predicted to arrive very soon and you'd best
pick up your barometer and head inland as fast as you can.
