Retrograde. Planets seem to move forward and then backward sometimes. This is really because we pass them as we move in our orbit but astronomers wanted to try to describe the solar system with earth at the center so elaborate models were employed.
Hello!
I'm just going to ignore the name of the building and just do the math
1 foot is equivalent to 0.3048 meters
if the building is 1368 feet tall, multiply it by 0.3048 to get 416.9664 meters
I hope this helps, and have a nice day!
Answer:
a = 5
Explanation:
F = M × A
15 = 3 × a
a = 15 / 3
a = 5
This is only if the toy can is pushing the book or smth coz the question looks incomplete...?
Answer:
50% of unpolarised light passes through the first filter because, on average, 50% of the waves are aligned with the fiter's axis. Intensity is reduced by a factor 0.5.
The second filter then reduces the intensity by a factor cos²(θ)
Explanation:
Answer:
α = 11.05 rad/s^{2}
Explanation:
torque (T) = 2.1 N.m
moment of inertia (I) = 0.19 kg.m^{2}
angular acceleration (α) = ?
from torque = moment of inertia x angular acceleration
2.1 = 0.19 x α
α = 11.05 rad/s^{2}
