Answer:
360 J/kg/°C
Explanation:
Heat lost by metal = heat gained by water
-m₁ C₁ (T − T₁) = m₂ C₂ (T − T₂)
-(0.059 kg) C (27.4°C − 221°C) = (0.409 kg) (4186 J/kg/°C) (27.4°C − 25°C)
(11.4 kg°C) C = 4109 J
C = 360 J/kg/°C
Por the impulse, use the formula:
I = F * t
Now, we know:
4000 N = 4000 kg*m/s²
Replacing we have:
I = 4000 kg*m/s² * 0,200 s
Resolving:
I = 800 kg.m/s²
The impulse is <u>800 kg.m/s²</u>
Answer:
It is hard to explain, but just go on YT, and look up how to draw a heating curve.
Explanation:
Tectonic plates under the ground ,either go on top of each other or crash.
Answer:
Momentum of bullet

momentum of baseball

Explanation:
As we know that momentum is defined as the product of mass and velocity
here we know that
mass of the bullet = 8 gram
velocity of bullet = 340 m/s
momentum of the bullet is given as



Now we have
mass of baseball = 0.2 kg
velocity of baseball = 40 m/s[/tex]
momentum of baseball is given as
