Answer

Delta Q = change in thermal energy = c M * change in temperature

change in temperature = Q / (c * M)

change in temperature = -12 J  / (390 J / Kg*deg * .012 kg

change in temp = -12 / (390 * .012) =  - 2.56 deg C

The acceleration of gravity on Earth is approximately 10 m/s2 (more precisely, 9.8 m/s2). If you drop a rock from a tall buildin
mars1129 [50]

Answer:

30 m/s

Explanation:

Velocity is v_{final}=v_{initial}+at since we know that the initial velocity is 0, and the acceleration is 9.8 \frac{m}{s^2} \approx 10 \frac{m}{s^2} then we also know that time is 3 seconds it follows that: v_{final}=v_{initial}+at=0+10\frac{m}{s^2}*3s=30\frac{m}{s}

A container has a large cylindrical lower part with a long thin cylindrical neck open at the top. The lower part of the containe
Brums [2.3K]

Answer:

8.6*10^5N

Explanation:

Pressure of the water = density of water * height of the water * acceleration due to gravity

Pressure of water = 1000*9.81*(2.5 + 8.50)

Pressure of the water = 107910 = 1.08*10^5

And Pressure = force / A

Force = Pressure * A(surface area of the container)

Force = 1.08*10^5 * 8 = 863280 = 8.6*10^5N

A satellite with mass 500 kg is placed in a circular orbit about Earth (Mass= 5.98 x 10^24 kg), radius = (6.4 x 10^6), a distanc
gizmo_the_mogwai [7]

Explanation:

a) F = GmM / r²

F = (6.67×10⁻¹¹) (500) (5.98×10²⁴) / (6.4×10⁶ + 1.5×10⁶)²

F = 3200 N

b) F = ma

3200 = 500a

a = 6.4 m/s²

c) a = v² / r

640 = v² / (6.4×10⁶ + 1.5×10⁶)

v = 7100 m/s
