Speed is measured in miles per hour. You have miles, so convert minutes to hours.
90 minutes x 1 hour / 60 minutes = 1.5 hours
540 miles/ 1.5 hours = 360 miles / hour
Hope I helped, even though this isn't Chemistry :)
Density is defined as Mass per unit volume of an object ~
And hence, the correct choice is ~ 1
Using the specific heat capacity formula:
q = mc ∆ t
60.0 J = (6g)(x)(11*C)
x = 0.9 J/g*C
Aluminum
Answer:
2
Explanation:
energy produced in nuclear fusion or even fission is due to mass defect and it can be calculated by Einstein equation e=mc2
Thrust acts on the spacecraft and propels in the space.
<h3>How space shuttles move?</h3>
1. The force created by the shuttle's engines in expelling the burning fuel produces an equal thrust in the opposite direction. This thrust acts on the spacecraft and propels in the space.
2. The thermosphere and the stratosphere are our hottest atmosphere layers because these two layers are present near the sun as compared to other layers of atmosphere.
3. When the meteors hit the atmosphere, meteors rub against air particles and create friction which is heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
