Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
Explanation:
Answer:
Correct answer: F = 5.075 N
Explanation:
The formula for Newton's Second Law is
F = m · a = 0.145 · 35 = 5.075 N
God is with you!!!
The answer would be 5.6x10^5
Answer:
1) Li = 0048678 kg -m^2/s
2) 0.129483 joule
3) 3.4745 Rad/s
4) 0.08456 joule
Explanation:
1) INITIAL ANGULAR MOMENTUM
we know that
2) INITIAL ROTATIONAL KINETIC ENERGY
3) FINAL ANGULAR VELOCITY
from conservation of angular momentum
Li =Lf
= 3.4745 Rad/s
4) FINAL ROTATIONAL KINETIC ENERGY
A 2.0 kilogramme chunk of heated copper is cooled by being lowered into 5.0 kg of water. Water goes from 30 degrees Celsius to 52 degrees Celsius in only a few hours. determine the copper's temperature before submerging it in water. In this case, the water's temperature is 24 degrees, and when we plug this number into equation 2 for water, we get the copper's temperature as 100 (0.387) (200-x) = 400 (4.187). ( x-20)
100 (0.387) (200-x) = 400 (4.187) ( 24-20)
: to give (something) over to the power or control of another : surrender The troops would not yield the fort to the enemy. 2 : to give in He yielded to temptation. 3 : to produce as a natural product These trees yield fruit.
Solving it yields x = 26.89 degrees, indicating that the temperature of ;copper is 26.89 degrees.
