Impulse=force*time
impluse=120N*2.0s
impluse=240 Ns
Answer:
J = 14.4 kg*m^2
Explanation:
Assuming that the wheel is not moving anywhere, and the kinetic energy is only due to rotation:
Ek = 1/2 * J * w^2
J = 2 * Ek / (w^2)
We need the angular speed in rad / s
566 rev/min * (1 min/ 60 s) * (2π rad / rev) = 58.22 rad/s
Then:
J = 2 * 24400 / (58.22^2) = 14.4 kg*m^2
Answer:
A. The time it takes for the water to boil
It is because salt was added into the water. So the responding variable is the time taken to boil the water.
hope this help u. good luck
Space probes send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. Whereas, an analog device transmits through electromagnetic waves and electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. The natural space radiation environment can damage electronic devices so an analog device cannot be used. Hope this helps!
But they would be able to use analog devices in the future, if they create suitable protection for it.
