Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
Answer:
a. Big Bang Theory explains the beginning of the universe. The entire matter of the universe is believed to be concentrated in a single point. This point had infinite density. At time, t = 0, at the big bang, universe started expanding and cooling down. This theory is most widely accepted theory describing the beginning of the universe. It is not considered as hypothesis because of the evidences received by the scientists- detection of cosmic microwave background, red shift of the light received from the galaxies indicating that universe is expanding.
b. Cosmic Microwave background radiation is a faint radiation having average temperature of 3 K detected every where around from the sky. This is a residual radiation from 400,000 years after the beginning of the universe. The universe was very hot and dense at the beginning and thus, opaque. Hence, detection of the CMB has provided the evidence of Big bang theory.
c. Scientists have proposed three models of the universe:
1. closed universe- The universe has finite volume and curves around itself. The space-time has positive curvature.
2. open universe - The universe has infinite volume and has a negative curvature.
3. flat universe - The universe has zero curvature. It has infinite volume. The actual density of the universe is equal to the critical density of the universe. The expansion rate slows down over time. This is the most widely accepted model.
Answer:
Explanation:
Given:
m=0.504kg
r=5.37mm
metal cylinde factor=2.31
we know that
Upward force = Downward force
Net force
Answer:
Explanation:
Hello.
In this case, since the force is defined in terms of the mass and acceleration by:
We can easily compute the mass by solving for it:
Whereas the force is 182 N (kg*m/s²) and the acceleration is 13 m/s², therefore, we obtain:
Best regards.
In order to answer that question, we would need to know something about the rocket's climb.
Any of these would do it:
-- its speed when it reaches 85 km
-- its acceleration on the way up
-- the time it takes to reach 85 km.
