Explanation:
003 (part 1 of 2)
Pressure is force divided by area.
P = F / A
P = (117 kg × 9.8 m/s²) / (2 × (0.05 m)²)
P = 229,320 Pa
003 (part 2 of 2)
There are approximately 6895 Pa in 1 psi.
P = 229,320 Pa × (1 psi / 6895 Pa)
P = 33.3 psi
004 (part 1 of 2)
Since the collisions are elastic, the angle of reflection is the same as the angle of incidence (it bounces off at the same angle).
Impulse = change in momentum
F Δt = m Δv
F (36 s) = (300 × 0.003 kg) (5.2 sin 57° m/s − (-5.2 sin 57° m/s))
F = 0.218 N
004 (part 2 of 2)
Pressure is force over area.
P = F / A
P = 0.218 N / 0.712 m²
P = 0.306 N/m²
<span>LOCATION Z, because it is only 2 away from the coast.
The rest are farther inland

They don't need gas because satellites rotate around the world using our planet's gravitational force as centripetal force. That as well as since there is no air in space, it doesn't have to work against air resistance. This way it doesn't lose energy by going around and around the Earth.
Hope this helps, have a BLESSED day! :-)
Answer:
0.240 J/g/°C
Explanation:
q = mCΔT
47.3 cal = (55.00 g) C (15.0°C)
C = 0.0573 cal/g/°C
Usually, specific heat is measured in J/g/°C, so we can convert:
C = 0.0573 cal/g/°C × 4.184 J/cal
C = 0.240 J/g/°C
Any true element (including copper) is by definition a "pure" substance. As there are no other elements in it, if you were to include any other elements it would become a compound or mixture of elements.
are kilograms (kg)
are metres (m)
