Answer:
0.0365 A
Explanation:
Data provided in the question:
Peak value of the voltage, V = 17.0 volts
Resistance of the resistor, r = 329.0 ohm
Now,
The rms current () is given by the relation as:
on substituting the respective values, in the equation, we get
or
= 0.0365 A
Hence, the rms current is 0.0365 A
Answer:
Explanation:
It is given that Hair dryer , Toaster and coffeepot are working simultaneously with power 1200 W , 700 W and 800 W respectively.
So the total power of system is
it is given that they work properly until toast is on.
By switching on the toast, appliance stop working because it may cause the circuit to break to safeguard the circuit.
Circuit breaker frame are used in home to prevent the short circuit
Explanation:
760 mmHg (millimeters of mercury) is a measure of atmospheric pressure. It represents the height of a column of mercury at which the static pressure at the bottom is equal to the atmospheric pressure.
1 atm = 760 mmHg = 101,325 Pa = 14.7 psi
Answer:
The correct option is;
B. Subtract vectors A from C; = 12 N
Explanation:
The given parameters are;
The weight of the dresser = 250 N
The force applied by the man = 20 N = C
The frictional force provided by the carpet = 8 N = The component of the weight resisting motion = A
Therefore, the net force tending to put the dresser in motion, , is given as follows;
= The force applied by the man, C - The frictional force provided by the carpet which is the component of the weight resisting motion, A
= C - A = 20 N - 8 N = 12 N
= 12 N
The resulting net force, = 12 N.
