Answer:
The answer is C 0.0
Explanation:
Because its sitting still on the ground.
Before answering this question it is necessary to know the conversion factors for temperatures.
<em>273 k = 0 ° C
</em>
To transform a temperature from Kelvin to ° C we use the following Formula
T ° C = T Kelvin - 273
<u>For 373 K</u>
373K -273 = 100 ° C
<em>373 Kelvin equals 100° C.
</em>
To transform a temperature from ° C to ° F we use the following formula:
(T° C x 9/5) + 32 = T ° F
Then:
<u>For 0 ° C
</u>
(0° C x 9/5) +32 = 32 ° F
<em>0° C equals 32 ° F.
</em>
<u>For 100° C
</u>
(100 ° C x 9/5) +32 = 212 F
<em>100 ° C equals 212 ° F.
</em>
Therefore, the correct option is the first:
373 Kelvin = 100 ° C = 212 ° F
Answer:
Explanation:
Mass of the bucket, m = 23 kg
Radius of the pulley, r = 0.050 m
The bucket is released from rest, u = 0 m/s
The time taken to fall, t = 2 s
Speed, v = 8.0 m/s
Moment of Inertia of the pulley, I = ?
Using the equation of motion:
v = u + at
8 = 0 + 2a
a = 8/2
a = 4 m/s²
The relationship between the linear and angular accelerations is given by the equation:
Angular acceleration, 
Since the bucket is falling, it can be modeled by the equation:
mg - T = ma
T = mg - ma = m(g-a)
T = 23(9.8 - 4)
The tension, T = 133.4 N
The equation for the pulley can be modeled by:
The force of gravity that the sun
exerts on a planet is directed toward the sun. I am hoping that this answer has
