Answer:
a. Doppler and transit observations.
Explanation:
By means of the dopler effect, the radial velocity of an extrasolar planet can be measured, this is achieved by observing Doppler shifts in the spectrum of the star around which the planet orbits. This measure, combined with the transit observations, makes possible determine the density of the planet.
An image that can be projected on a screen is a real image. A real image can be larger than the original object.
good luck
Answer:
The automated system that uses an automated work cell controlled by electronic signals from a common centralized computer facility is "Robotics"
Explanation:
Robotics is an advanced technology fully automated which uses electronic sensors incorporated with the combination of control into mechanical systems greatly enhancing the performance and flexibility of the systems. This is possible with the advances in hardware, software, and control programming systems which amounts to extensive automation from a common centralized computer facility.
Answer:
each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance
Explanation:
d = Diameter of the wheel
The distance traveled in one rotation of the wheel is the circumference of the wheel
When diameter is 24 inches
Therefore, each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance
Power is energy/time where energy is in joules and time is in seconds. The units for power is watts, W.
P = 500J/30s = 16.67 W
Hope this helps!
