Momentum before collision must be equal to momentum after collision
(m1<span> + m</span>2)v = m1v1<span> + m</span>2v<span>2</span>
3.62g*270 m/s=2.30kg* (x)
convert the units to be the same that is convert the kg mass to grams
1kg=1000g
2.30kg=y
230/100*1000=2300g
3.62*270=2300X
977.4g/m/s=2300X
977.4/2300=0.4250M/S
Finding a velocity after the gun is embedded on the block of wood
3.62*270+2300g*0.425=(3.62+2300)*V
977.5+977.5=2303V
1955=2303V
V=1955/2303
V=0.8489M/S
Answer:
I think c is correct options....
Explanation:
The resistance of the wire increases with increase in temperature. The resistance does not depend on the weight of the wire. Therefore, the correct option is weight.
Momentum and inertia,
Momentum=P. P=MV. M=mass and V=velocity. Mass is related to inertia so inertia=F. F=MA. A=acceleration.
The answer is A bc when warm, moist air from the Gulf of Mexico and cool and dry air from Canada
