Answer:
the answer is a)5.82s
Explanation:
Hello!
The first thing we must understand to solve this exercise is that a capacitor has the following characteristic function
where
Vo=initial voltage
V=voltage in an instant of time
t=time
R=resistance=4000Ω
C=capacitance=2.1-mF=0.0021F
we must consider that the final voltage is half of the initial voltage so we deduce the following equation
V=Vo/2
Now we replace in the initial equation, and start an algebraic process to find t
finally with the equation ready, we use the resistance and capacitance values to find the time value
the answer is a)5.82s
Answer:
0.47922 kgm/s and will move right to left
Explanation:
= Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g
= Mass of veggieburger-on-a-bun = 351 g
= Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s
= Velocty of veggieburger-on-a-bun = -2.47 m/s
Left to right is considered positive direction and the opposite is negative direction
Net momentum is
The combined dish has a momentum of 0.47922 kgm/s and will move right to left
