A couple of things, if the shuttle burned all of it's fuel before entering Earth's atmosphere then that means that the shuttle was accelerating towards Earth until it ran out of fuel. At that point, there is little to no air resistance (friction) by the lack of an atmosphere so it keeps accelerating due to Earth's gravitational force. The closer the shuttle gets to Earth the stronger the gravitational pull the shuttle experiences. Note that, once the shuttle reaches Earth's atmosphere it will cause significant amount of friction and thus will cause the shuttle to slow down.
You look up the element in the periodic table. Subtract the atomic number (small number) from the mass number (big number). The answer is the number of neutrons.
Answer:
The
Explanation:
The horizontal distance covered is known as the range expressed as;
R = U√2H/g
U is the speed = 200m/s
H is the max height = 800m
g is the gravity = 9.8m/s²
R = 200√2(800)/9.8
R = 200√1600/9.8
R = 200√163.27
R = 200(12.78)
R = 2555.54
Hence the package should be released at a distance of 2555.54m
The second law of thermodynamics states that whenever energy changes occur, DISORDER always increases.
The magnitude of the acceleration of block m2 is 0.09 m/s² and the tension in the cord is 1.8 x 10⁻³ N.
<h3>Acceleration of the blocks</h3>
The acceleration of the blocks is calculated from the net force on the blocks.
∑F = ma
a = ∑F/m
a = (F) / (m₁ + m₂)
where;
- F is the horizontal force applied
- m₁ is mass of first block = 40 g = 0.04 kg
- m₂ is mass of the second block = 20 g = 0.02 kg
a = (0.03)/(0.04 + 0.02)
a = 0.09 m/s²
<h3>Tension due to block m₂</h3>
T = m₂a
T = (0.02 x 0.09) = 1.8 x 10⁻³ N
Thus, the magnitude of the acceleration of block m2 is 0.09 m/s² and the tension in the cord is 1.8 x 10⁻³ N.
