Answer:
2
Explanation:
length of the raft, L = 2 m
Width of the raft, W = 2.5 m
height of the raft, H = 9.8 cm = 0.098 m
mass of each person, m = 75 kg
Density of wood = 650 kg/m^3
volume of raft, V = L x W x H = 2 x 2.5 x 0.098 = 0.49 m^3
let there are N persons
According to the principle of floatation
Buoyant force acting on the raft = True weight of the raft
Volume x density of water x g = volume x density of wood x g + N x mg
0.49 x 1000 x g = 0.49 x 650 x g + N x 75 x g
490 = 318.5 + N x 75
N = 2.28
So, the maximum number of person is 2.
inflation theory
steady state theory
big bang theory
Answer: oscillating universe theory
Explanation:
The Oscillating Universe Theory suggests that for every big bang there is a big crunch, imagining the universe as undergoing endless cycles of expansion and contraction.
The theory that suggests that for every big bang, there is a big crunch is known as the oscillating universe theory. This theory proposes that the universe undergoes endless cycles of expansion (Big Bang) and contraction (Big Crunch). It's like a ongoing cosmic heartbeat, where our universe alternatively expands and contracts.
The other three theories mentioned, the inflation theory, the steady state theory, and the big bang theory, each have their own illustrations of the universe's formation. None of them, however, necessarily involve the concept of a big crunch following a big bang.

Answer is D.the distance between the focal point and the center of the lens.
Answer:
it is B i took the test and got it wrong when someone said it was A
Explanation:
it is the one that says the sizing of the objects will appear unusual
False
False
If the object weighs more than the buoyant force then the object will sink.
This is because the buoyant force "pushes" the object upwards and the weight of the object "pushes" the object downwards. Since the force downwards is greater than the force upwards the item will sink, so this statement is False.
