Solid because the particles vibrate in place
Answer:
Magnetic field, 
Explanation:
It is given that,
Velocity of proton, 
Magnetic force, 
Charge of proton, 
We need to find the strength of the magnetic field if there is a 45° angle between it and the proton's velocity. The formula for magnetic force is given by :
B = 0.0000416 T
Hence, this is the required solution.
Answer:
R = 150 ohms.
Explanation:
According to Ohm's law,
V = IR
V = voltage across the walkman = 1.5 V (we assume that the battery has no internal resistance)
I = current used by the walkman = 0.01 A
R = resistance of the circuit = ?
1.5 = 0.01 × R
R = (1.5/0.01)
R = 150 ohms
Hope this Helps!!!
Coal is founded in regions that had dense forest (mainly rainforests). Fue to natural causes, they gpt buried deep under the ground and due to extreme pressure and temperature, they got converted into coal.
The regions that had relatively less dense forests, have less coal today.
