Answer:
yes
Explanation:
The metal is closer than 20 cm to the magnet which is in the magnetic field.
Answer:
We know that loudness is directly proportional to amplitude and SI unit of amplitude is Decibel So unit of loudness is decibel
Answer:
60 m/s (in the opposite direction)
Explanation:
By conservation of momentum,
Initial momentum of board + Initial momentum of man = Final momentum of board + Final momentum of man
=> 0 + 40*12 = 8*(-v) + 0
=> v = -60 [ Negative indicates opposite direction ]
<h2> Charge = 25.9
</h2>
Explanation:
Given,
The average current (I) = 
and
Time period (T) = 0.133 s
The charge is calculated by multiplying the current to the time period.
Hence,
To find, the charge delivered to the ground by the lightning bolt(Q) = ?
By applying the formula of charge that is-
Charge(Q) = 
∴ Charge(Q) = 
= 25.89111 
= 25.9 
<h3>Thus, the charge of 25.9
is delivered to the ground by the lightning bolt.</h3>
Answer:
Thermal energy
Explanation:
I believe it is because the movement of particles has a connection with the temperature. Example: Since gas particles move very fast, it must be hot and freshly occurred through heating process.
