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.

B. density=mass*volume
C. density=volume/mass
D. density=mass + volume
Answer:
My answer is A.
Explanation:
by using a density triangle, you would have to cover up the density and then it will show you, m over v. so that means you would have to divide.
Answer:
The friction coefficient is .
Explanation:
Given that,
Mass of first box = m
Mass of second box = 3m
Let the static friction force on the less massive box is .
Since the small box is not slide, they have the same acceleration.
We need to calculate the acceleration
Using balance equation
....(I)
....(II)
Adding both the equation
Put the value of a in equation (II)
We need to calculate the friction coefficient
Using formula of frictional force
Hence, The friction coefficient is .
-The momentum of player A is greater than that of player B.
-The momentum of player A is less than that of player B.
Answer:
the momentum of player A is greater than player B.
Therefore, Option 2 is correct.
Step-by-Step explanation:
We have been given the velocity of the players and mass of the players.
Player A:
Velocity is 5m/hr
Mass 210 pounds
Player B:
Velocity is 3m/hr
Mass 190 pounds
We have a formula for momentum:
p is momentum
m is mass
v is velocity
We will find momentums for both the players:
Momentum of player A:
on substituting the values we get:
Momentum of player B:
on substituting the values we get:
Hence, the momentum of player A is greater than player B.
Therefore, Option 2 is correct.
The equation for momentum is p = mv where p is the omentum, m is the mass and v is the velocity. Calculating the momentum for each football player, player A will have a momentum of 1050 lb-mi/h and player B will have a momentum of 570 lb-mi/h. Therefore, momentum of player A is greater than that of player B.
b. no waste
c. radioactive waste that can be released into local water supplies
d. air pollution
Nuclear power plants produce radioactive waste that must be stored properly in other to prevent pollution and health hazards.
Nuclear power plant refer to the thermal power station in which power is generated and the the heat source is a nuclear reactor. In any thermal power stations, heat is used to generate steam that spin up steam turbine connected to a generator that produces electricity.
Therefore, Nuclear powerplants produce radioactive waste that must be stored properly.
