Answer:
0.038 m/s, 0.0096 m/s²
0.101
0.103
Explanation:
The speed is given by
v = 2πr / T
v = (2 * π * 0.15) / 25
v = 0.9426 / 25
v = 0.038 m/s
Acceleration, a is given by
a = v² / r =
a = 0.038² / 0.15
a = 0.001444 / 0.15
a = 0.0096 m/s²
Ratio of apparent weight to true weight at the top
w = m (g - a) / (m g)
w = 1 - a/g
w = 1 - 0.0096 / 9.81
w = 0.9904 / 9.81
w = 0.101
Ratio of apparent weight to true weight at bottom
w = m (g+a)/ (m g)
w = 1 + a/g
w = 1 + 0.0096 / 9.81
w = 1.0096 / 9.81
w = 0.103
Heat energy required to change the temperature is given by
here we know that
now from above formula we will have
So it will remove 28255.5 J heat from the water
Paper..pencils...tables, walls...everything that is man made science played a huge factor in it because the first science was when some hairy dude was like i wonder what happens when i do this...same thing with food and drinks..how do you think milk was made..some dude was like hmmm..i wonder..and i think you can figure out the rest..hope i helped
It is a comet that was a comet
Answer:
Explanation:
Initial angular speed of the ferris wheel is given as
final angular speed after friction is given as
now angular acceleration is given as
now torque due to friction on the wheel is given as
Now the power required to rotate it with initial given speed is
