Just assume that the sun has the average mass of all the stars
Then divide the mass of the galaxy by the mass of the sun.
<span>10^30 has 30 zeroes after it. 10^42 has 42 zeroes.
The answer would have 12 zeroes which concludes a trillion stars. </span>
C. a lot of inertia.............................. :-)
30*3*60=5400
300*2=600
1500*3=4500
200*10*60=120000
the computer uses more energy.
(you can multiply all results by 60 to get the energy in J, but it's not necessary for the comparison)
Explanation:
The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.
Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units
Answer:
The back end of the vessel will pass the pier at 4.83 m/s
Explanation:
This is purely a kinetics question (assuming we're ignoring drag and other forces) so the weight of the boat doesn't matter. We're given:
Δd = 315.5 m
vi = 2.10 m/s
a = 0.03 m/s^2
vf = ?
The kinetics equation that incorporates all these variables is:
vf^2 = vi^2 + 2aΔd
vf = √(2.1^2 + 2(0.03)(315.5))
vf = 4.83 m/s
