This problem is asking for the required heat to change the temperature of 500 g of water by 50 °C. At the end, the result turns out to be 25,000 cal as shown below:
<h3>Calorimetry</h3>
In science, calorimetry is the process whereby objects lose or gain energy according to the decrease or increase of their temperature. Thus, for these problems, we need to use the following equation:
Where Q stands for the heat, m for the mass, C for the specific heat of the object and T for the temperature (final and initial). Thus, for this problem, since it is about water, one fixes its specific heat as 1 cal /(g-°C) in order to obtain the following:

Bob gained (80lbs x 14ft) = 1120 ft-lbs of energy.
Fred gained (110lbs x 14ft) = 1540 ft-lbs of energy
Since they both took the same amount of time, Fred's power (rate
of doing work) was greater than Bob's power (rate of doing work).
Answer:
Explanation: p = mass x velocity = m x v. • p = 1000 x 30 . The product of the force (F) acting on an object and applied force) A 1000 kg Civic is traveling at 30 m/s and ... What is the momentum of the car after accelerating for ... If a 5kg object experiences a 10 N force . Solve: Honda, Camry, collision ... v = -15 m/s
Answer:
Explanation:
Let the length of the string is L.
Let T be the tension in the string.
Resolve the components of T.
As the charge q is in equilibrium.
T Sinθ = Fe ..... (1)
T Cosθ = mg .......(2)
Divide equation (1) by equation (2), we get
tan θ = Fe / mg
As θ is very small, so tanθ and Sinθ is equal to θ.
Answer:
One of the leading theories of hot-Jupiter formation holds that gas giants in distant orbits become hot Jupiters when the gravitational influences from nearby stars or planets drive them into closer orbits. They formed as gas giants beyond the frost line and then migrated inwards.
Explanation:
In the migration hypothesis, a hot Jupiter forms beyond the frost line, from rock, ice, and gases via the core accretion method of planetary formation. The planet then migrates inwards to the star where it eventually forms a stable orbit. The planet may have migrated inward smoothly via type II orbital migration.
Hot-Jupiters are heated gas giant planets that are very close to their stars, just a few million miles distant and orbiting their stellar hosts in just a few days. The reason why there isn't one in our Solar System is down to its formation. All gas giants form far from their star but then some migrate inwards.
Hot-Jupiters will just happen to transit about 10% (that is, since orbital planes) this is consistent with the rate expected from geometry of . The actual frequencies of hot Jupiters around normal stars is surprisingly hard to figure out.
