A solid is a firm shaped with packed components
Ex.
- Ice
- Wood
- Brick
- Crayon ( not yet melted)
Given:
P = 1000 W, power input
c = 4190 J/(kg-K), the specific heat of water
m = 1 kg, mass of water
ΔT = 10 °C = 10 K, temperature rise.
Let t = time required to raise the temperature f the water.
Then
P*t = m*c*ΔT
(1000 J/s)*(t s) = (1 kg)*(4190 J/(kg-K)*(10 K)
1000t = 41900
t = 41.9 s
Answer: 41.9 s or 42 s (approximately)
Answer:
I believe it is C
Explanation:
When the water freezes the kinetic energy decreases because it is staying in place instead of moving around, which also causes thermal energy to decrease.
Answer:
Explanation:
Unstable nucleus tends to emit small particles of matter(alpha or beta particles) with an attendant emission of electromagnetic radiation and some amount of energy.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures stability of the nucleus.
Any nucleus with a neutron/proton combination different from its stability ratio (i.e either too many neutrons or too many protons) will be unstable and split.
The will emit some small particles and radiations until they become stable.
Answer:
HP = 27.08 hp
Explanation:
The complete question has a theoretical flow rate of 18.2 GPM. So, to find the input horsepower, we will use the following formula:
HP = QP/1714(E)
where,
HP = Input Horse Power = ?
Q = Volume Flow Rate in Gallons Per Minute (GPM) = 18.2 GPM
P = Outlet Pressure in psi = 2372 psi
E = Mechanical Efficiency = 0.93
Therefore,
HP = (18.2 GPM)(2372 psi)/(1714)(0.93)
<u>HP = 27.08 hp</u>
