Micheal told me in the closet I got some chicken I'm so sad
Answer:
Sam's momentum as he leaves the jump is 1350 kg *m/s.
Explanation:
To solve this problem, we must remember the formula for momentum:
p = mv
Where p represents the momentum of the function, m represents the mass of the object, and v represents the velocity of the object
Now, to solve, we must simply plug in our values into this equation.
p = mv
p = (75 kg)(18 m/s)
p = 1350 kg *m/s
Therefore, your answer is 1350 kg * m/s.
Hope this helps!
Answer: 1560632 joules
Explanation:
The change in thermal energy (Q) required to heat ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = ?
Mass of frozen water (ice) = 1kg
C = 4184 J/(kg K)
Φ = (Final temperature - Initial temperature)
= 100°C - 0°C = 100°C
Convert 100°C to Kelvin
(100°C + 273) = 373K
Then, Q = MCΦ
Q = 1kg x 4184 J/(kg K) x 373K
Q = 1560632 joules
Thus, the change in thermal energy is 1560632 joules
