Answer:
TRUE
Explanation:
When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.
Answer: it’s B -3x-5
Explanation: just answered it and got it correct.
Answer:
2.5 g/cm³
Explanation:
To find density, divide the mass by the volume. In this case, 15 grams divided by 6 cm³ equals 2500 kg/m³, or simplified, 2.5 g/cm³. Hope it helps! To type ³, turn on Num Lock and then press Alt+0179. Have a good day!
Answer:
The value is 
Explanation:
From the question we are told that
The mass is 
The diameter is 
The angular speed is 
The mass of each of the blocks is 
Generally the radius of the turntable is mathematically represented as

=> 
=> 
The moment of inertia of the turntable before the blocks fell is mathematically represented as

=> 
=> 
The moment of inertia of the turntable after the blocks fell is mathematically represented as

=> 
=> 
Generally from the law of angular momentum conservation

Here
is the initial angular momentum of the turntable before the blocks fell which is mathematically represented as

and
is the initial angular momentum of the turntable after the blocks fell which is mathematically represented as

So

=>
