Answer:
Stretch and moving away from us, with more distant ones moving faster
Explanation:
Astronomers observed that the entire universe is getting bigger because distant galaxies appears to be moving away from us
Answer: Yes
Explanation:
A ruber band can be described by his mas, M, the spring constant K, and his rest radius, wich is the radius of the circular rubber band when there is no force applied to it, so yes, a uniform thin circular rubber band of mass M and spring constant k has an original radius R
Answer:
- collecting information
- imaging
Explanation:
Remote sensing means we do not have to be physically present in that particular area that we're studying by taking certain measurements. Several tools have been developed overtime to enable us to make this feat possible. Satellites in orbit have a major role to play in this regard. They exist to gather information from outer space and captures images that help us know more about our universe.
Hope that answers the question, have a great day!
Answer:
work done is 470400 J
Explanation:
given data
long = 3 m
wide = 2 m
deep = 4 m
density = 1000 kg/m³
to find out
Find the amount of work in joules
solution
we know here volume = area × length
so
area = 0.5 ×base×height
area = 0.5 ×2×4
area = 4 m²
so volume = 4 × 3 = 12 m³
and
weight of water = volume ×density×g
weight = 12 × 1000 × 9.8
weight = 117600 N
so
work done = weight × height
work done = 117600× 4
work done = 470400 J
