Answer:
C
Explanation:
Definition of drug: a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body
Answer:
A capacitor with capacitance C is initially charged with charge q. At time t=0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (see image below)
What is the current I0 that flows through the resistor immediately after the switch is thrown? Express your answer in terms of any or all of the quantities q, R, and C.
Explanation:
charge on the capacitor,
q = CV
C is the capacitance of the capacitor
V is the voltage across the capacitor
Determine the current flowing through the resistor after the switch is thrown
According to Ohm’s law, current flowing through the resistor is ,
V is the voltage across the resistor
R is the resistance of the resistor
since
Current through the resistor immediately after the switch is thrown
Acceleration of the cabinet= 0956 m/s²
Explanation:
Total force=25+18=43 N
mass of cabinet=45 kg
now F = m a
a= F/m
a=43/45
a=0.956 m/s²
Thus the acceleration of the cabinet=0.956 m/s²
Answer:
56.25 watts
Explanation:
P = F * d / t
P = Power (it's an unknown at this point).
F = 450 N
d = 25 steps each 10 cm = 25 steps 0.1 m/step = 2.5 m
t = 20 s
Solution
P = 450 * 2.5 / 20
P = 1125/20
P = 56.25
