D. The density of the sir increases and the air rises.
When coming in contact with the kettle, it becomes hot, it expands and rises up, due to lesser density as compared to the surrounding air.
Answer:
radio telescope, because it captures radio waves from space
Explanation:
The technology the scientists used to capture the image is likely to be a radio telescope. This telescope is able to produce images from electrical signals transmitted by the radio waves the trail of the asteroid generates.
- Telescope are used to study very far and distant bodies.
- So, due to their special design, it is the best instrument to use for this kind of study.
- The radio telescope picks radio waves produced from astronomical bodies in space.
Winter weasels, also called ermines or short-tailed weasels, have coats that turn from light brown to white in the winter. The color change begins at their stomachs and works its way outward, occurring in both spring and fall. Other species, like the long-tailed weasel, may turn at least partially white as well.
The length of daylight, not temperature, prompts the color change. As a result, weasels in winter may be stark white against a brown landscape before snow starts to fall. During warmer winters, this makes them easy prey for larger predators such as foxes, martens, and badgers.
Answer:
23.8 N
Explanation:
Given that
Mass of the first box, m = 24 kg
Mass of the second box, M = 62 kg
Pushing force, F = 33 N
There is an acceleration, a in between the system and another force, f in between both blocks. Thus, we can say, using Newton's law
F - f = m.a
f = M.a
If we add both equations together, we have
F = m.a + M.a
F = (m + M) a
33 = (24 + 62) a, making a subject of formula, we have
a = 33 / 86
a = 0.384 m/s²
Recall, from the second equation,
f = M.a, now, if we substitute for both, we get
f = 62 * 0.384
f = 23.8 N
The magnitude of force the 24 kg applies to the 62 kg is 23.8 N
