Answer:
Explanation:
Amount of gold deposited = 0.5 g
Gold's molar mass = 197 g/mol
Time duration, t = 6 hours
= 6 × 3600
= 12600 s
Calculation of moles: mass/molar mass
= 0.5/197
= 0.00254 mole
Assuming
Au --> Au+ + e-
Faraday's constant = 9.65 x 10^4 C mol-1
Charge, Q = 96500 × 0.00254
= 244.924 C
Relation: Q = I × t
Thus, I = 244.924/12600
= 0.011 A
= 11.34 mA.
Conclusion:
The total net force acting on the objects is 16 N, directed towards the right.
Clarification:
It is stated that,
The force exerted by the dog, 
(to the right)
The force exerted by Simone, 
(backward)
Here, assume the backward direction is negative and the right direction is positive.
The net force will move in the direction where the larger force is present. The net force can be calculated as:
F = 16 N
Thus, the net force amounts to 16 N, acting towards the right.
Answer:
v = 66.4 m/s
Explanation:
We know that the aircraft starts off moving at a speed of
now we have
in the Y direction, we can apply kinematic equations
as there is no acceleration along the x-axis, the velocity in this direction remains unchanged
thus yielding
Mike will get an electric shock. Explanation: The human body acts as a conductor of electricity. When lightning strikes the rod, it acquires a negative charge and immediately discharges this charge when contacting the ground through conductive materials. As a result, Mike is likely to endure a significant electric shock as the negative charge travels through his body to the other rod and into the ground, potentially leading to numbness or even loss of consciousness.
The response is 176 minutes. The translation of 456 g equals 0.456 kg. The specific heat of ice is 2093 J kg⁻¹, used to calculate heat required for a 25-degree rise, determined by mass multiplied by specific heat and temperature increase. The necessary calculations yield a total heat load of 176164 J. Finally, by dividing heat required by heat supply rate, we ascertain that it will take approximately 176.16 minutes.
