X = v0+ 1/2 a t^2
X= 0+1/2(12 m/s^2 ) ( 7 s)^ 2
X= 6 m/s^2 ( 49 s^2)
X= 294 m
The gas will remain a gas and the energy will be transformed into heat raising the temperature
(Some very rare exceptions might occur)
Answer: velocity = 50m/s
Distance moved=5m
Explanation:
Using the formula Ft=Mv i.e impulse= momentum
Where F= force ,t= time, M= mass, v = velocity
In this case we need to find v,
F,t,M are all given in the question.
Therefore, substituting the values we have
250N×0.1s=0.5kg×v. Mass=500g= 0.5kg
v=25/0.5= 50m/s
The distance the puck will move when it is on his stick.
D= Velocity × time
D=50m/s × 0.1s
D=5m
Goodluck...
Answer:
Cuolomb is SI unit of charge
1 e=1.6022E-19 C
1 C = 6.2415E+18 e
Explanation:
Coulomb(C) is the SI unit for measuring electric charge and is given as the product of current and time. To convert Cuolomb to electron, we multiply each cuolomb of charge by 1 C = 6.2415E+18 e while to convert electron into charge, we multiply the electrons by 1e=1.6022E-19 C
