The first object also has half the inertia.
Answer: Option A
<u>Explanation:</u>
Inertia is the tendency of an object to remain in its state. It resists the change in the state of object due to any external forces. So the inertia is the property of an object to resists the change in its state due to any kind of external force. Thus as the mass decreases, the central mass of inertia of the object will also decrease as both are directly proportional to each other.
Answer:
d.all of the above
Explanation:
The physical feature of the planet Earth affect people's activities in the following manner -
- Choice of Occupation - the process of occupation is completely a land depended process , hence any changes on the physical features of Earth , like the climate , temperature , rain etc , will hinder the occupations process .
- Method of transportation - it is also a Climate dependent process , so any change in climate may obstruct the transportation facility .
- Recreational activities - also depends on the physical feature of the planet Earth .
Complete question is;. A 73mH solenoid inductor is wound on a form that is 0.80m long and 0.10m in diameter a coil having a resistance of 7.7 ohms is tightly wound around the solenoid at its center the mutual inductance of the coil and solenoid is 19μH at a given instant the current in the solenoid is 820mA and is decreasing at the rate of 2.5A/s at the given instant what is the induced current in the coil
Answer:
6.169 μA
Explanation:
Formula for induced EMF is given by the equation;
EMF = M(di/dt). We are given;
di/dt = 2.5 A/s
M = 19μH = 19 × 10^(-6) H
Thus;
EMF = 19 × 10^(-6) × 2.5.
EMF = 47.5 × 10^(-6) V
Formula for current is;
i = EMF/R. R is resistance given as 7.7 ohms.
Thus; i = 47.5 × 10^(-6)/7.7
i = 6.169 μA
Answer:
The apparent weight of the person as she pass the highest point is 
Explanation:
From the question we are told that
The radius of the Ferris wheel is 
The period of revolution is 
The weight of the person is 
Generally the speed of the wheel is mathematically represented as
substituting values
The apparent weight (the normal force exerted on her by the bench) at the highest point is mathematically evaluated as
Where m is the mass of the person which is mathematically evaluated as
substituting values
So
