To answer the question the antenna would probably burn up in the atmosphere. I have no idea how to get that thing on Earth if it's by itself. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
- Velocity is a vector quantity, which consists of a magnitude (the speed) and a direction. In the case of the circular motion, as in this problem, the speed is constant (45 m/h), but the direction is constantly changing, so the velocity is changing as well.
- Acceleration is also a vector quantity, whose magnitude is equal to the rate of change of the velocity, and the direction is given by the change in direction of the velocity. Therefore, since the velocity is changing, the acceleration in this problem is changing as well.
Answer:
Explanation:
The final angular speed of the system is given by the help of the Principle of the Angular Momentum Conservation:
The final angular speed is:
Finally, the change in the rotational kinetic energy is:
Answer:
Explanation:
Given
No of lines in the grating (N)=900 slits per centimeter
Distance between screen and grating(L)=2.78 m
Slit width(d) =
We know distance between two maxima
therefore
<u>for instance, steel has a higher thermal conductivity than plastic. Hence, the steel plate gives away heat to the ice block faster than a plastic block does. As a result, ice melts faster on a steel plate than on a plastic one. Faster an object draws heat, the colder it feels.</u>
